Explaining what mufflers do is pretty easy, they make a vehicle run quieter. However, explaining how a muffler does this is harder than you think. Believe it or not, inside your common muffler are chambers as finely tuned as a musical instrument.Sound is a wave formed from pulses of alternating high and low air pressure, basically air molecules in motion. In an engine, the pulses are created when exhaust valves open and high-pressure exhaust gas bursts into the exhaust system. Now comes the interesting part: It is possible to produce a sound wave that is exactly the opposite of another sound wave.

muffler

If this is done right and you can get the two to hit each other, they cancel out. That’s right, the sound actually disappears.

This noise cancellation technique is not the only thing going on in your muffler. For example: the body of a muffler is generally constructed in three layers. This allows the body of the muffler to absorb some of the pressure pulses so they don’t cause the muffler body to act like a drum.

Engineers have to be careful when they design mufflers, though, because they don’t want too much “backpressure”. This subtracts a little from the power of the engine. For those that this is a big disadvantage, like high performance and sports cars, there are other types of mufflers that can be used that have minimal backpressure.

Several car manufacturers have been experimenting with high tech active noise-canceling mufflers. These systems actually incorporate microphones and speaker devices in the exhaust pipe. The speaker device is positioned in the pipe and a computer monitors the noise. By knowing some things about the length and shape of the pipes, the computer can generate a signal to cancel out exhaust noise.

The battery in your car is probably going to need a “jump” at some point because it has run out of power.

This usually happens when headlights or an internal light have been left on for a long time.

It can especially quickly in the wintertime. Never done it before? Here’s a quick guide.

  1. Find someone with a battery under the hood of their car to jump you (some cars have batteries in the trunk. These are generally quite hard to get to.)
  2. Make sure someone has a good pair of jumper cables.
  3. Bring the two cars close together. Head to head is ideal but side-by-side is OK too.
  4. Make sure both cars are turned off. Put automatic transmission cars in Park, manuals in Neutral. Engage the parking brakes on both cars.
  5. On the batteries, look for “+” sign (red) indicator for positive, and “-” sign (black) indicator for negative.
  6. Attach one end of the positive cable (red) clamp to the positive terminal of the “dead” battery. Attach the other end of the positive cable to the positive terminal of the “good” battery.
  7. Attach one end of the negative cable to the negative terminal of the “good” battery. Attach the other end of the negative cable to the negative terminal of the “dead” battery.
  8. Start the engine of the good car. Allow it to run for 1-2 minutes while reving the engine slightly by pressing on the gas pedal lightly.
  9. Attempt to start the engine of the dead car. It may take more than one try, but do not try to restart it more than three or four times.

The dead car still won’t crank:

If the dead car doesn’t make a loud clicking sound when you turn the key, the booster cables may not have good connections. Try rocking the cable clamps slightly back and forth to get the clamps to dig into the terminals.

If the engine still won’t start, allow the good car to run for 10 or so minutes while hooked up to the dead car. Rev the engine slightly. This may build enough of a charge in the dead battery to allow you to restart. If these steps do not work after three or four more tries, stop trying to jump-start. There is probably something else that is preventing the car from starting.

You’ve finally decided that the next vehicle you get is going to be an crossover sedan. You’ve done all your research; you’ve picked out the model, engine size and trim you want but one decision remains: do you go for the 2WD or the 4WD version?First, let’s consider a fact- many crossovers never go off-road. Even though they look like they are ready to tackle muddy backroads, most are only used to go shopping or hauling the kids. Frankly, in applications such as these, you really don’t need a 4WD. But, that being said, let’s look at the technical differences between 2WD and 4WD vehicles.

2WD Vehicles

Important data point, most 2WD vehicles are really 1WD. What? Under slippery conditions, a single wheel transfers power from the differential to the road and the other one coasts. This can be problematic when conditions are slippery – especially when stuck in snow. To make a vehicle a true 2WD, a limited slip differential is required. Limited slip differentials make sure that both wheels receive power. If you opt for a 2WD crossover, be sure the manufacturer offers the option of a limited slip rear differential.

There are other reasons that a 2WD is an excellent option also. They are typically lighter than 4WD vehicles (no 4WD components) and get slightly better gas mileage. Maintenance costs are typically lower over the life of the vehicle also as there are fewer moving parts to wear out.

4WD Vehicles

Drivers who want 4WD vehicles typically have many variations to choose from. “Part-time 4WD” refers to one of the most commonly used 4WD systems. It employs a simple high/low transfer case which routes power equally to the front and rear differentials. When engaged, both sets of front and rear wheels turn at the same rate of speed. This is great for slow speed travel but not good for highway travel. For highway travel, it is best to turn a part-time 4WD system off.

“Full-time 4WD” use front, rear and center differentials to allow the speed of individual wheels to vary. vehicles so equipped can operate in the 4WD mode at all times and on any surface condition. When disengaged, full-time 4WD operates as normal 2WD and thus save fuel.

All-wheel drive (AWD) systems are very popular today. AWD means the system is permanently engaged at all times. Power is sent to any or all wheels, controlled by a series of electronic gears that detect wheel slippage. AWD on crossovers and other smaller vehicles is not intended for off road use.

Lasers have an illuminating power 1,000 times more powerful than LEDs – which up until just recently provided the greatest illumination power of all the automotive technologies.

Laser technology has some compelling advantages over standard illumination system too.

For example: laser automobile lights can be much smaller than conventional lighting systems and they look pretty darn cool (a big selling factor).

Audi Sport quattro laserlight concept-1

We know what you are thinking, can’t lasers hurt your eyes? Not a problem here, because of the way that the beam energy is directed, and then ultimately is displayed out of the headlight housing, is “indirect”. What happens with each headlight is that three blue lasers positioned at the rear of the assembly fire onto a set of mirrors closer to the front. Those mirrors focus the laser energy into a lens filled with yellow phosphorus. The yellow phosphorus, when excited by the blue laser, emits an intense white light. That white light shines backward, onto a reflector then the reflector bounces the more diffused white light forward to illuminate the road. No direct laser beams exit the assembly.

Because laser-powered headlight systems can be much smaller than standard headlights, they open up a new world for automotive designers. Designers now have a larger palate to use when crafting the front of new automobiles. They have more flexibility to make more aerodynamic shapes or just to fit more stuff into the engine compartment with the freed-up space.

None of the major automobile manufacturers have said when laser-powered headlights will be a regular option on their production vehicles. Given the “arms-race” nature of the auto business, it’s probably a safe bet that all of them are working on them. We will likely be seeing a great deal more about automotive laser illumination systems in coming years.

When it comes to increasing engine performance, there are a wide variety of performance parts on the market, and most are designed to do one thing: increase the amount of air and fuel the engine can pull into the cylinder on the intake stroke. The more air and fuel the engine can pack into the cylinders on the intake stroke, the greater the peak horsepower of the engine.There is another method, though, that doesn’t require standard hot rodding tricks like changing blocks, pistons, camshafts and such engine hardware. It simply introduces a gas called nitrous oxide into the engine and this can create an astonishing amount of additional power.

BMW Z4 by MB Individual Cars-1

To understand how nitrous oxide works, let’s quickly review how an engine operates. A gasoline engine’s operation depends on three factors: fuel, air and spark. The engine takes in air and fuel and ignites it with the spark. The ignited mixture results in hot, exploding gases that push pistons down their cylinders, turning the crankshaft rapidly and transferring power downstream to the wheels.

Nitrous oxide is a gas composed of two nitrogen molecules bonded to one oxygen molecule, hence, the chemical name of N2O. It stays in liquid form under pressure and converts to a gaseous state when released into the atmosphere. Nitrous oxide is an oxidizer. An oxidizer enhances combustion by supplying additional oxygen to the burning process. Initially, the nitrous doesn’t help the process. Only after nitrous has been exposed to the heat of the combustion process will the chemical bond between the three atoms be broken allowing the free oxygen molecule to contribute to the combustion process. The end result is more horsepower being created pretty much the same way a blower or turbocharger does.

There are two main types of nitrous systems for automotive performance use – wet and dry systems. Wet nitrous systems come with their own fuel hardware which allow you to introduce more fuel to your intake charge and increase horsepower. Dry nitrous systems, on the other hand, don’t come with hardware and use your existing fuel system components. Dry nitrous systems are generally easier to set up between the two simply because you don’t have the added fuel components to install. Most do-it-yourselfers prefer dry systems

Cost? You can purchase a nitrous kit, brand new for around $500 with everything you really need to start using it, maybe as much as $700 if you get all the bells and whistles. With kits in this price range you can instantly add some 15, 35, 55, 65, 75, 125 or even 150 horsepower to your car. The nitrous refills are about $40-50 or so at the time of this writing.

Safety and legality is one concern that should be addressed. Nitrous is not without risk. Compressed gas has to be treated with respect. A punctured compressed gas container can become a rocket, and excessive heat can cause a compressed gas container to explode. Check your local laws because in some states it is illegal to have nitrous in the vehicle, in others it’s legal with certain rules (can’t be open/hooked up), and in others there are no regulations on the books at all.

If you are considering a nitrous system for your car you will find a huge amount of information on the web. There are many reputable nitrous system dealers in addition that can provide you with invaluable support if you decide to “add the juice”.

In the summer of 2014 the Ford Fiesta officially became the best-selling car of all time in Great Britain after 38 years on the market. Ask a sample of ten UK car owners and it’d be surprising if at least one of them didn’t own one of the many versions of this acclaimed vehicle.

Not every version of the Fiesta has been hailed a classic yet it has remained extremely popular, consistently leading car sales throughout the past four or so decades. So what is it about this car that has helped it sell so well?

Ford Fiesta Red and Black Editions-1

Economical

As a supermini the Ford Fiesta needed to be affordable to become a success. Now in its seventh generation, relatively it is still as affordable as when it launched, both in terms of price and fuel economy. Most new versions are far heavier than the original Mk1 but also give back almost double the mpg of the original.

New Ford Fiestas have also been released at the right time. Even during financial slumps their sales have remained steady due to attractive prices, decent quality and sheer popularity. Leasing options through places such as LeaseCar.co.uk have made brand new models affordable for those on a tighter budget too.

Reliable

Few things become so popular without good reason and the Ford Fiesta has plenty to back up its popularity. A reliable runner, the fact so many people drive them encourages those looking for new vehicles that they must be good, reliable cars. Word of mouth soon spreads too and the car’s genuine reliability furthers its appeal. With so many produced and on the roads parts and insurance are cheap as well. Feedback from faults has led to further improvements on newer models, helping it go from strength to strength.

Stylish

From its boxy origins to the sleek and modern design of its latest incarnation, the Ford Fiesta has always been in fashion. Numerous variations of each model has made it popular as everything from a family car to a souped up boy racer.

Never possessing any bold features that may put off potential owners, settling on a solid base and updating it to a more rounded and now swished back look has kept the Fiesta’s aesthetic stylish. Even the older Mk 1 and 2 models now hold a certain amount of retro appeal. It may not be British owned but the Ford Fiesta has become a staple of the country’s automobile landscape.

There is no car manufacturer more synonymous with speed and style than Lamborghini. The Italian car giant has been going since 1963 and over the past half a century, Lamborghini has released some of the greatest cars the world has ever seen. They combine luxury, speed and incredible designs in a totally unique way. Even a car novice can spot a Lamborghini from a mile away!That didn’t happen by accident though. The Lamborghini brand has seen a gradual progression through the years. Each model seems to build upon the one that came before while remaining identifiably related to one another. Here is the history of Lamborghini in 4 essential cars.

Lamborghini

Lamborghini 350 GT – 1964

The 350 GT was the very first car to be driven off the production line at Lamborghini. And what a start it was, it was evident from the very beginning that Lamborghini was a manufacturer to be reckoned with. It was revealed at the Geneva motor show in March 1964. It was well received, and its success gave the young company the kick start it needed.

At that point in time, the big player in the sports car market was Ferrari. Ferrari knew they had a serious challenger for the first time when the 350 GT landed though. It wasn’t yet the angular Lamborghini we’ve come to know now, but its style was undeniable.

Lamborghini-350GT

Lamborghini Countach – 1974

Although the 305 GT was great and iconic, you could say that the Lamborghini we now know and love really arrived in 1974 with the Countach. It was the first model to employ the iconic angular, wedge-shaped design that the manufacturer has since become synonymous with. The Countach pushed the boundaries of the mid-size sports car like no other before it.

It was also one of the first sports cars to reach 200 miles per hour. That’s no small achievement, and ti managed to cement the place of Lamborghini in the annals of sports car history. The car was even illegal in the United States until 1982, showing how advanced the car was seen as being.

Lamborghini Diablo – 1990

Unfortunately, the Countach ran out of steam and its production ended in 1988. But that paved the way and left the door open to the Lamborghini Diablo, which arrived at the very start of the nineties. A lot of people might see the Diablo as being a stepping stone between the Countach and the Murcielago. I think that position underestimated the power and beauty of the Diablo though.

The Diablo was a striking and remarkably fast car even before the GT version arrived. It wasn’t called Diablo, which means devil in Spanish, for no reason. It looked menacing with its orange, low to the ground body, and it had the speed too.

Lamborghini Diablo

Lamborghini Gallardo – 2003

For me, the best of Lamborghini’s most recent output is the Gallardo. It only arrived in 2003 but quickly became one of the most iconic cars the company ever made. There aren’t many prestige Lamborghini vehicles that have this much pull and sway with the consumer. And it wasn’t just a hit with customers either, it goes around the track like no Lamborghini before it.

No car arrives without influence, but Lamborghini have made it their mission to create a continuing line of cars, each one building on the one before it.

The nature of the enthusiast means they’ll always be on the look out for ways they can improve the performance of their car. The problem is, making what seemed like a small adjustment can spiral into a situation that leaves you with a pricey mechanics bill.While an interest in car tuning and modification certainly opens up the door to an interesting hobby, it’s typically advised that those without sufficient knowledge do some research the subject before getting their hands dirty. Here’s some must-know tips before you get started on your first project.

Start with a Professional Servicing

Before invest any of your time and money, you should start by having your car serviced by a professional. You should start by asking your mechanic to make sure that all of the critical components are operating correctly. Tuning the engine can induce compromises that reduce the lifespan of the components. Because of this, you’ll want to ensure that the engine is in good mechanical order beforehand so you don’t waste your effort on something that’s already burned out.

Make Sure You Plan Ahead

As with any project, it’s crucial that you plan ahead of time. It’s not enough to just to know how to make the changes, you should also know how to reverse them if the situation comes to that. If you are knowingly making a modification that is permanent, make sure you know what you’re getting yourself into ahead of time. This is even more important if you are working on the vehicle that you use for day-to-day use. Consider what you’re doing an investment, and invest in the right parts and evaluate the different options available to you.

Invest in the Proper Tools

Even an experienced mechanic wouldn’t be able to do the job right without the proper tools. This is why it’s important to buy the right equipment from reliable suppliers. SGS Engineering stock a variety of tools, from air wrenches, drills, and cut saws, to get the job done whether you’re planning on tuning the engine, altering the interior, or modifying the bodywork of the vehicle. While you shouldn’t make alterations that drastically outweigh the value of the vehicle, it’s also not an area where you want to cut cost on the essentials.

Modifying your car is a great way to express your creative side and also learn about how your vehicle works. It shouldn’t be taken lightly, though, so make sure acknowledge the risks.

Leasing a car brings with it many advantages over buying the same vehicle.

Not only do you get the chance to spread the cost of the vehicle out over several years, at the end of the contract you can upgrade to something even better.

However, there are several mistakes people often make when leasing vehicles.

Running into Excess Mileage

As well as the length of your contract and the make and model of your vehicle, one of the most important factors in determining your monthly rate is the mileage limit that you agree to. Many leasing companies set a maximum of between 12,000-15,000 miles per year so it’s crucial that you understand how far you travel on an annual basis. If you drive more than this, leasing a vehicle may not be for you. If you’re worried about exceeding your limit, though, consider going slightly over your usual rate. This will give you some leeway if you professional or personal situation changes over the course of the contract.

Fair Wear Agreements

The “fair wear” agreement determines what you will have to pay should you return your vehicle in substandard condition. Fair wear often refers to things like small dents or scratches, light carpet wear, and slight wear to instruments like the gear stick or steering wheel. What it doesn’t cover is damage caused by misuse or an accident. If you want to learn more about this agreement, take a look at this helpful guide that covers all the usual questions. Remember, if you damage the vehicle, you still have the opportunity to have it repaired before you hand it over. Leaving it to the leasing company to assess the value may end up costing you more.

Terminating Your Contract Early

Leasing contract are generally last between two and four years. If you find yourself in a situation where you would like to end the contract early—for instance, if you can no longer afford the monthly rate or even if you would prefer to switch to another vehicle—you can choose to terminate your contract early. However, this will come at a high cost and should only be done when absolutely necessary. Depending on your lender, there may be a clause you can add at the beginning of the contract to slightly lower this fee.

Leasing a car can be a great alternative to buying outright, but it’s not without problems. Make sure you know what you’re getting in to before you sign the dotted line.

Those who have them know it better, the problem is not acquiring the ride; maintenance is. Keeping your car in good working condition and perfect shape is not easy. Just like a child, it needs to be under close supervision nearly every time. Making the car retain its sleekness and perfect design is therefore not an easy task. However, you can always make a choice of having your car remain awesome in all seasons and throughout the year. The secret is in the accessories you add to it.There are always different car accessories often available for cars.

Porsche 911 (991) Carrera S by KTW Tuning and TechArt-1

It remains your choice on which one to go for. Regardless of your interest, however, there are always some accessories that will go down in most cars and still make them maintain their perfect look without many efforts. Some of them are included below.

New 2X Car 8 LED DRL Driving Daytime Running Day LED Light Head Lamp Super White

This is one of those accessories that every car should have. Most people would not see their importance, but those who have in the past tried them out know how good these accessories are. It is so easy to use and quiet simple to install. It mainly features super beam daytime running light to driving safety. The LED itself guarantees longer lifetime. On average, it can go for over 50,000 fully operational hours. What makes them amazing is their minimal power consumption making them very energy effective. Compared to a standard bulb, it consumes far much less power yet the light output is better than that of the bulb. This means it is a very good deal to go for and there is no doubt about it. The maintenance cost is also minimal making it quite a perfect cost effective accessory.

It majorly focuses on enhancing the total appearance of the extra cool white beam to the car at daytime. For oncoming motorists, it increases reaction time meaning you will be safe in case of incidents requiring attentions. It slim design is super attractive and more its adjustable brackets which fits different car models. With is a waterproof reflector for all weather road conditions. You can, therefore, rely on them whether or not there is sunshine. It is so easy to install and you will no doubt find easy time doing so. During the installation, however, precautions should be taken not to start the process without first disconnecting the power. This way, you will remain safe during the short time that installation takes. It is approximated to cost $7.7 or less. You can, therefore, acquire it for your car without any financial constraints.

Car Tire Pressure Gauge Metal Auto Truck Racing

At least every time before leaving the house, it is wise knowing the pressure gauge of your tires. It can be disappointing realising the pressure in the tires is low when you are in the middle of nowhere. The experience itself isn’t such a pleasant one and those who have gone through it know better. This can always be avoided and that is the good news. By having your own pressure gauge metal, you can know when the pressure of your tires are enough or some adjustments are necessary. You can always achieve this by using Car tire barometer. This particular one is efficient for all types of cars. It is confirmed to contain a pressure gauge with a range of 10-100 psi and accuracy of 3psi. That implies you are less likely to go wrong when it comes to measuring the car pressure.

For accurate results and proper usage, always ensure that the gauge is set to zero. Before use, you need to push the nozzle onto the tyre valve in order to make a good seal between the valve and the nozzle. Doing otherwise might result in inaccurate reading which is worse off than no reading at all. Before taking the measurements, ensure that the pressure reading is stabilised. The gauge can then be removed from the valve stem and the measurements noted down. The numbers within this device are largely inscribed so you can always take a look without unnecessarily straining. To ensure it last longer, it comes with a metal protect shell. You will, therefore, be assured of having it for a considerable span of time without it getting spoilt. It is very light in weight and therefore easily portable. You can as well carry it on your journey so that you use it just in case the need for it arises. It barely costs $4, a price that is considerably low.

Car Cigarette Lighter Socket Splitter Charger USB 3 Sockets

In your car, you should have everything you might possibly require for both leisure and work. These include both the basics and even leisure accessories like cigarette lighters. Everyone else is doing the small portable one so you can as well decide to acquire the cigars lighter socket splitter. This accessory comes with a wide range of applications. For one, it can be used in lighting cigars as the name suggests. When you use it this way, it increases, your cigarette lighter from 1 to three sockets. It also has an additional USB port which you can use for various duties. The connection is always very simple. You only need to plug it into the car cigarette lighter socket and it will start working without any efforts.

You can have it running multiple accessories all at the same time. It is, therefore, multipurpose and can serve a wide range of duties. It is so convenient to use. With it is a Triple socket with 12V/24V output. It also comes with LED charging indicator. In addition, it has a built-in fuse to help in the prevention of over current. That means your electronic devices are as well protected. Mostly, it comes in the dominant black colour but there are always options of other colours which are not so common though. It is estimated to cost $3.90 dollars, which are very cost effective. It is worth trying out; you will live to appreciate acquiring it.
