Turbocharger is actually an air compressor to increase air flow through the air. It is the use of engine exhaust turbine inertia momentum to drive the turbine chamber, turbine and driven coaxial the impeller, the impeller pressure delivery pipe sent by the air filter air, so that pressurized into the cylinder. Faster when the enginespeed, exhaust emissions are also synchronous speed and turbine speed faster, impeller to compress more air into the cylinder, the air pressure and density increase can burn more fuel, increase the amount of fuel and adjust the engine speed , you can increase the output power of the engine.
Introduction
Participate in sports car competition generally in the engine is equipped with turbochargers to burst out of the car more power. Engine by the combustion of fuel in the cylinder to produce power, the amount of fuel input by the inhalation of air within the cylinder limit, the power generated will be limited, if the engine’s operating performance has been at its best, to increase the output power only by compressing more air into the cylinder to increase the amount of fuel to improve combustion acting ability. In the current technical conditions, the turbocharger is the only way the efficiency of the engine in the case of constant output power increase of the mechanical device.
Advantage
The biggest advantage of turbochargers is no increase in engine displacement will be able to sharply increase the engine power and torque, in general, after the installation of booster engine power and torque to be increased 20 % to 30%. Turbocharger lag disadvantage is that, due to the inertia of the impeller when sudden changes in throttle response on the slow, delayed increase or decrease the engine output power, which to a sudden acceleration or overtaking a car, the moment will not pull its weight a little to mention feeling.
In the last 30 years, turbochargers have been spread to many types of vehicles, which make up a number of inherent naturally aspirated engine, the engine displacement in the case does not change can increase the output power of 10% or more. So many car manufacturing companies are using this technology to improve the engine’s turbocharger output power, in order to achieve high performance cars.
China is currently on the market of vehicles with turbochargers are Audi 1.8T, Passat 1.8T.
