A turbocharger is actually an air compressor that uses compressed
air to increase the amount of intake air. It uses the inertial
force of the exhaust gas from the engine to push the turbine in the
turbine chamber. The turbine drives the coaxial impeller. The
impeller presses the air sent by the air filter pipe to pressurize
it into the cylinder. When the engine speed increases, the exhaust
gas discharge speed and the turbine speed also increase, the
impeller compresses more air into the cylinder, and the increase in
air pressure and density can burn more fuel, correspondingly
increase the fuel amount and adjust the engine speed. It is
possible to increase the output power of the engine.
The turbocharger has five main advantages:
1. Increase the engine power. In the case of constant engine
displacement, the engine can be injected with more fuel, thereby
increasing the power of the engine. The power and torque of the
engine after the supercharger is increased by 20% to 30%.
Conversely, under the same power output requirements, the cylinder
bore of the engine can be reduced, and the size and weight of the
engine can be reduced.
2. Improve engine emissions. The turbocharger engine reduces the
displacement of harmful components such as particulate matter and
nitrogen oxides in the engine exhaust by improving the combustion
efficiency of the engine. It is an indispensable configuration for
diesel engines to meet Euro II emission standards.
3. Provide the function of altitude compensation. In some
high-altitude areas, the higher the altitude, the thinner the air,
the engine with a turbocharger can overcome the power drop of the
engine caused by the thin air of the plateau.
4. Improve fuel economy and reduce fuel consumption. Since the
engine with turbocharger has better combustion performance, it can
save 3%-5% of fuel.
5, with high reliability and good matching characteristics, high
transient response characteristics.
