What is the role of auto intercooler?


1.The temperature of the exhaust gas discharged by the engine is very high, and the heat conduction through the supercharger will increase the temperature of the intake air. Moreover, the density of air will increase in the process of being compressed, which will inevitably lead to an increase in air temperature, thereby affecting the charging efficiency of the engine. If you want to further improve the charging efficiency, it is necessary to reduce the intake air temperature. Data shows that under the same air-fuel ratio, the engine power can be increased by 3% to 5% for every 10°C drop in the temperature of the supercharged air.
2. If uncooled supercharged air enters the combustion chamber, in addition to affecting the charging efficiency of the engine, it is also easy to cause the engine combustion temperature to be too high, causing malfunctions such as knocking, and it will increase the NOx content in the engine exhaust gas. Cause air pollution.

Therefore, in order to solve the adverse effects caused by the temperature increase of the supercharged air, it is necessary to install an intercooler to reduce the intake air temperature.
