Universal Exhaust helps to boost the performance of your car engine. They are long lasting and priced reasonably at a low cost. The exhausts are meant to squeeze out as much power as possible from the engine of the car. Since the engine works properly and efficiently, it means that it does not use as much fuel as it did earlier. This helps in attaining fuel economy. A good system is quite affordable. They are also quite easy to install. With the ever-increasing rise in the cost of gas, exhaust systems come as a great way to gain fuel economy. Car manufactures have to balance a lot of aspects while designing a car. They have to take care of cost, performance, weight, gas mileage noise and innumerable other factors. Thus they will not be able to provide you the best of exhaust system, as that would send the price of the vehicle skyrocketing.

The manufacturers also have to abide by various EPA noise restrictions. Thus they cannot customize cars for all its buyers as they have a huge customer base. But on the other hand, the moment you buy the vehicle, you are free to carry out any kinds of modifications. You can install Exhausts - Universal Exhaust in the car to give your vehicle an energy boost. Many people do not give too much importance to exhaust systems. They feel that the exhaust systems are there just to discharge the waste products. True. This is exactly what the exhaust system does. But the way the wastes are flushed out of the car engine is crucial to the performance of your vehicle. Exhaust performs basically three functions.

The first is to canal out the wastes from the process of burning so that the engine is able to continue with the process and as a result performs smoothly. A good exhaust system permits the waste products to get out of the system rapidly. If these waste products get clogged in the engine, then the whole system will choke. it also helps to reduce the noise that is produced in the engine. The waste gases and compounds go out of the engine at very high pressure. If these gases were allowed to escape from the engine directly, then it would generate tremendous amount of noise. So in order to reduce the noise, exhaust systems channels the gases via metal plates and tubes known as muffler. The muffler ensures that the noise is minimized.

Another important task of the exhaust is to clean up all the emissions that may prove harmful to the environment. When the engine burns the fuel, it emits harmful gases like hydrocarbons, nitrogen oxides and carbon monoxide. The exhaust system, with the help of the catalytic converter, cleanses these gases by breaking down the damaging gas compounds. The chemicals present in the catalytic converter act as catalyst. They change the extremely dangerous gas compounds into less destructive ones. In this era of environment conservation, it is almost a criminal offence in some countries not to have a catalytic converter. The converter is very important for the better performance of any exhaust system. Thus if your catalytic converter is not up to the mark, then you need to replace it immediately.

If your exhaust system is not designed properly, then it will make a lot of noise. Also it may harm the performance of your car. So, if you want your car to perform at its optimum, then you must invest in a good exhaust system. The systems are quite reasonably priced, so you need not worry.

Modern Car exhaust system are a much needed item.

Hcci, General Motors’ Clean and Efficient Engine in One

A dark blue Saturn Aura is turning around the ovals of General Motors. It may look like any fresh model set for drive testing, but under the hood of this vehicle is an experimental engine that General Motors believe is the next milestone for fuel economy and emission control. Together with this Aura, GM is introducing the world the homogeneous-charge compression ignition engine (HCCI). Aside from other electrical connectors, this engine sets the Saturn Aura from other engineering prototypes.

According to GM’s researchers, the HCCI engine runs on a combustion process that holds the potential for advancements in fuel efficiency. Although several auto companies are developing the same system, GM is one of the pioneers.

The HCCI engine has the finest engine qualities, diesel engines that offer low fuel consumption and technology controlled low emissions.

As of now, further refinements will be needed for the engine. When it will be ready for the road, is the question that GM cannot answer at the moment. GM’s engineers and computers will maintain the engine on its operating range. According to experts, the works will be worth the investment.

In a New York Times interview with Chris Gerdes, associate professor of mechanical engineering at Stanford University, he was quoted saying “I believe H.C.C.I. represents the next great advance of the internal combustion engine,” The renowned

University is part of the HCCI research with GM.

“With minimal changes to the engine hardware, H.C.C.I. gasoline engines should be able to produce diesel-like efficiencies while simultaneously lowering emissions,” he further stated on the same interview.

The engine has the potential to raise fuel efficiency by 15 percent to 20 percent and at the same time, it will cause oxides of nitrogen reductions said Dennis Assanis, director of the Walter E. Lay Automotive Laboratory at the University of Michigan.

The 2.2 liter engine used in the Aura test was basically based from the GM Ecotec 2.4 liter four cylinder engine available in the Aura next year. A power of 180 horsepower and 170 pound-feet of torque is expected to be generated from the HCCI engine. On the other hand, the engine of the 2008 Aura will be generating a lesser power of 164 horsepower and 159 pound-feet.

The HCCI engine works by igniting an equal distribution mixture of fuel, air and exhaust gas. Like how diesel engine works, combustion is spontaneous from the heat in the cylinder.

“H.C.C.I. relies on a very delicate balance of chemistry happening thousands of times per minute in the cylinder,” said Paul Najt, a manager in G.M.’s powertrain research laboratory in his interview with the NYT.

“Controlling the chemistry is the difficult part to implement,” he said. “If the temperature and gas composition aren’t precisely correct, either nothing happens or something very bad happens.” He added. Mr. Najt had been working on the HCCI project for more than 30 years.

Aside from GM (factory manufacturer of Geo Catalytic Converter), other international auto companies are on their works for engine development. Volkswagen is developing their Combined Combustion System; Mercedes-Benz will be publicizing the details of their Controlled Auto Ignition Sytem and Honda with their own HCCI which was originally for racing motorcycles and is now tested in a four-cylinder car engine.

Was told i need to change my Catalytic Converter on my 1999 Mercury Cougar?

was searching on line for parts, but when looking at the description i see front passenger and back converter? are there two that's needed for this car? and universal converters are opinions on those?
thanks
definitly going to let a shop do it, i just want to go in with my own part and pay only for labor. i have been taken before on parts alone and always come out cheaper when i come in with my own parts. i ask about the universal converters because i don't plan on keeping the car but so long. so there are two converters on this car?

Go with a cheap converter and when you have it changed, ask for the old one. A lot of shops will try to sell you one even if you don't need it due to the fact that the material inside the converter is expensive and a top dollar scrap metal. Some are worth upwards of 600 bucks and some are worthless. I do believe yours is bad due to the age, but be aware of your trashes worth.

2002 Nissan Altima S review from North America
What things have gone wrong with the car? The first problem was that the headlight case literally melted at 50,000 miles. It was replaced by Nissan under a recall, but only after the problem had occurred.
