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.
