The purpose of the intercooler installation is mainly to reduce the intake air temperature, the working principle of turbocharging, simply by using the exhaust gas of the engine to impact the exhaust vanes, and then driving the other side of the intake vanes, forcing the compressed air and sending it to the combustion chamber. In the middle, since the temperature of the exhaust gas is usually as high as 8, 9 Baidu, the turbine body is also in an extremely high temperature state, so that the temperature of the air flowing through the intake turbine end is increased, and the compressed air is also generated. Heat (because the distance between the compressed air molecules becomes smaller, they will squeeze each other and rub to generate thermal energy). If this high temperature gas is not cooled into the cylinder, it will easily lead to excessive combustion of the engine, and then the gasoline will be pre-ignited. The knocking occurs, the engine temperature is increased, and the volume of the compressed air is also greatly reduced due to thermal expansion. As a result, the supercharging efficiency is reduced, and the power output is naturally not generated.
The high temperature of the intercooler is also the stealth killer of the engine. If you don't try to lower the operating temperature, you will be able to increase the chance of engine failure if you encounter a hot weather or a long drive. The cooler is used to lower the intake air temperature.
The intercooler is installed with the radiator of the water tank and installed in front of the engine. The air is cooled by the suction fan and the wind driven by the car. If the intercooler is poorly cooled, the engine will be insufficiently powered and the fuel consumption will increase. Therefore, it should be periodically The intercooler is inspected and maintained. The main content is: external cleaning. Since the intercooler is installed in the front, the intercooler fin passage is often blocked by leaves, sludge (hydraulic oil that overflows in the oil tank), etc. The heat dissipation is blocked, so it should be cleaned regularly. The cleaning method is to use a water gun with a low pressure to hang vertically from top to bottom or bottom to top at an angle perpendicular to the plane of the intercooler, but never to prevent it from damaging the intercooler.
