1, improve the engine power. In the case of the same engine displacement can be increased by increasing the intake density, so that the engine can fuel injection, so as to improve the power of the engine, the power and torque of the engine after installing the supercharger to increase by 20% ~ 30%. On the contrary, under the requirements of the same power output, the cylinder diameter of the engine can be reduced, and the volume and weight of the engine can be reduced.
2. Improve engine emissions. By improving the combustion efficiency of the engine, the turbocharger engine can reduce the emission of harmful components such as particulate matter and nitrogen oxides in the engine exhaust gas. It is an indispensable configuration for diesel engines to reach Euro 2 or above emission standards.
3. Provide the function of plateau compensation. In some high altitude areas, the higher the altitude is, the thinner the air is, and the engine with turbocharger can overcome the power loss caused by the thin air at high altitude.
4, improve fuel economy, reduce fuel consumption. Because engines with turbochargers burn better, fuel savings of 3 to 5 percent can be achieved.
