A Small Excursus Into The History Of Creation Of Turbochargers.

Posted: 11 Oct 2010 10:01 AM PDT

Engine builders, starting with Otto and Diesel, have always dreamed of as much as possible the filling of cylinders with air. But the engine had to “pump” itself with compressed air to avoid wasting energy. The more air in the cylinders, the more energy is that ultimately results in a significant increase in horsepower and torque.

Of course, the inventors have seized upon the idea of using energy of exhaust gases for pumping an air. While all this sounds simple, but it took many years before this idea could be realized – turbo appeared one hundred years after the invention of the internal combustion engine.

The first who described and patented the principle of the turbocharger was Alfred Buchli in 1905. Engineers have never faced with a problem of shortage of air, because even a small compressor can transmit a large amount of air. The problem was in the other, namely, how to control the boost pressure between the gears. Originally turbochargers mounted on aircrafts and ships. On these vehicles the engine speed changes smoothly. Then they started to install turbochargers on diesel engines. In 50 years of last century they began to install the turbines on racing cars, where the speed was approximately constant. In the same years, General Motors engineers equipped serial models with turbo engines, but then it was discovered pitfalls. During acceleration from low speed the compressor reacted very slowly. This fact was named “turbo lag” or “turbo hole”. At high speed turbochargers gave too much pressure.

By the end of 60-ies the Swiss engineer Michael May advanced the idea that the turbochargers needed to be done in small sizes, then they will give a smaller amount of air on the one hand and, on the other hand a small unit had a low weight, and that is why has less inertia and respond quicker to the change of the speed.

At the same time the company Porsche was also interested in the idea of a turbocharger. It jointly with the firm KKK in the early 70's initiated the era of automotive turbochargers. In the turbo engines, when you press the pedal of accelerator, pressure should to increase sharply, and when you release the bulldog – to fall sharply. They did in such a way: when the pressure became bigger, exhaust gases past bypass the turbine. When the throttle is closed, exhaust gases encounter. In this vane turbocharger is spinning, but not at full strength. When the boost pressure is necessary again, the bypass valve closes and the turbine spins faster.

There were many other problems, such as the temperature in the turbo-compressors of petrol engine reaches 1000 degrees, but all of these problems have been solved, and in our time turbochargers honestly serve to the good of mankind.

Long time ago car changed into not only a vehicle but also a luxury and entertainment object. Many people want to have powerful sport car but not everybody can afford it. There is a way out – turbo kits. Those who want to know how to make their car a unique masterpiece, go to this site. Lots of info about performance parts and how to order them.

The Main Advantages Of Turbochargers.

Recall how you felt having done several dozen of push-ups or having run through the three-kilometers of cross. Engine of your car feels the same when you go uphill or drive quickly on the highway.

More and more modern vehicles get a crisp air, which gives them an additional “force” from the turbocharger. Although the unit was used in the automotive, aircraft and other engines for most of the century, only about ten years ago the turbo was still considered only a “toy” for “exotic” and “very powerful” machines.

Together with the growing attention of the consumer to a higher and economical power of modern cars, turbochargers argued their high efficiency and practicality. Along with the low aerodynamic body shape of modern cars, their engines became less, and emphasis was placed on fuel economy.

The concept of turbo systems is as follows: turbine is an air pump driving by the exhaust gases. Due to this it is increased pressure of the air flow entering a motor, causing the air-fuel mixture enters the engine and there is an increase of power.

In some automotive engines the atmospheric pressure is the maximum possible pressure at which air flow can enter the engine. Number of burned fuel in the cylinders is limited because of the amount of air entering the engine at atmospheric pressure (such motors are not suitable for turbo).

The engine at the same speed can produce more power if more air-fuel mixture will get in the cylinders. The higher number of air-fuel mixture gives more pressure in the cylinder and a greater return. This is one of the ways to increase engine power. Turbocharged engine produces power by 30-60% more than the same engine without the turbine.

Turbocharger is an air compressor, which absorbs air and then compresses it and blows it into the engine. The compressor spins up to 100.000 rpm. through the turbine. Turbine with a compressor is combined with the shaft. When the turbine starts to rotate, it rotates the compressor through the shaft. The turbine rotates at the expense of the exhaust gas coming from the engine, after which the exhaust gases enter the exhaust system.

As mentioned above, the turbocharger increases the effective engine power by 30-60 percent. That is, after its installation, 4-cylinder aggregate provides the power options of 6 – and even 8-cylinder engines, and all this while maintaining high efficiency!

Benefits of the turbocharged engine.

The balance “weight / power” in the engine with turbocharger is higher than in atmospheric.

Turbocharged engine is smaller than atmospheric engine of the same capacity.

The curve of engine torque with the turbocharger can be better tailored to the specific conditions of operation. In this case, for example, the driver of a heavy truck can rarely change gears on a mountain road, and driving itself would be more “soft”.

Engine with turbocharger “does not notice” a change of height, when the atmospheric one at high altitude loses power.

Engine with turbocharger provides optimum combustion. Confirmation of this is the decrease of fuel consumption by trucks on the high mileage. Since the turbocharger improves combustion, it also helps to reduce emissions.
