Car turbocharger can lower engine emissions by burning fuel more completely and cleanly. This is because the turbocharger can make the engine take in more air, thereby increasing the oxygen content of the combustible mixture, making the fuel burn more fully in the cylinder, and reducing the harmful substances such as unburned hydrocarbons, carbon monoxide and particulate matter. emission. At the same time, the turbocharger can also reduce the operating temperature of the engine, thereby reducing the formation of temperature-sensitive pollutants such as nitrogen oxides. Therefore, after using the turbocharger, the engine can emit less pollutants under the same power, so as to achieve the purpose of environmental protection and cleanliness. Automobile turbocharger is a technology to reduce engine emission performance, which can effectively improve engine emission level and meet the standards.
