1. Increase the engine power. Under the condition that the engine displacement is constant, the engine can inject more fuel by increasing the intake air density, so as to improve the engine power. The power and torque of the engine with supercharger should be increased by 20% ~ 30%. On the contrary, under the same power output requirements, the cylinder diameter of the engine can be reduced, and the volume and weight of the engine can be reduced.

2. Improve engine emissions. The turbocharger engine reduces the emission of harmful components such as particulate matter and nitrogen oxides in the engine exhaust gas by improving the combustion efficiency of the engine. It is an indispensable configuration for the diesel engine to meet the emission standards above Euro 2.

3. Provide plateau compensation function. In some high altitude areas, the higher the altitude, the thinner the air. The engine with turbocharger can overcome the power reduction of the engine caused by the thin air on 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. It has high reliability, good matching characteristics and high transient response characteristics.
