1. Improve engine power performance. The lower intake air temperature increases the engine charging efficiency, thereby improving the engine power performance.
2. Reduce engine fuel consumption. The improved charging efficiency of the engine allows every drop of fuel to form a good flammable mixture with the air, and every drop of fuel is fully burned.
3. Reduce the possibility of engine deflagration. High temperature and high pressure air and fuel form a high temperature and high pressure combustible gas mixture, which is prone to deflagration in the engine cylinder. Reducing the intake air temperature can effectively suppress the engine knocking. Detonation can cause abnormal engine vibration and damage engine accessories.
4. Better adapt to the high-altitude working environment. The oxygen content at high altitude is low, and the charging efficiency is improved, so that the engine power can be continuously output.
The intercooler generally works in conjunction with the gas supercharger. The temperature of the intake air of the naturally aspirated engine is usually not too high, and the temperature of the gas compressed by the supercharger is very high. Especially the exhaust gas turbocharger, its power comes from the exhaust gas emission, and the exhaust gas temperature is extremely high, so that the temperature of the turbocharger body is also extremely high, and the air temperature passing through the exhaust gas turbocharger is naturally higher. For supercharged engines, the intercooler is a must exist mechanism.
