The temperature is increased, which not only affects the charging efficiency, but also easily causes knocking. Therefore, it is necessary to install a device that reduces the intake air temperature, which is an intercooler. It is installed between the turbocharger outlet and the intake pipe to cool the air entering the cylinder. The intercooler acts like a radiator, cooled by air or water, and the heat of the air is dissipated into the atmosphere by cooling. According to tests, a good performance intercooler can not only keep the engine compression ratio at a certain value without detonation, but also reduce the temperature to increase the intake pressure and further improve the effective power of the engine.
Due to the wide range of gasoline engine speed and large change of air flow, the shape of the compression impeller of the turbocharger is a complex ternary curved surface ultra-thin impeller blade. Generally, there are 12 to 30 blades arranged in a radial curve. The thickness of the blade is Below 0.5 mm, aluminum is made by special casting method. The shape of the blade directly affects the performance of the turbocharged engine. The more reasonable the angle of the impeller shape, the lighter the mass, the more sensitive the start of the impeller, and the smaller the "lag of reaction" of the turbocharger's natural defects.
In addition to lowering the temperature to reduce the possibility of detonation, a knocking sensor is also used. Its function is that when the knocking occurs, the sensor feels abnormal vibration will immediately feed back information to the engine ECU (electronic control unit) control system, which will ignite The timing is slightly delayed, and the normal ignition timing is resumed when no knocking occurs.
Since the car gasoline engine has a higher rotational speed than the diesel engine, the air flow rate is fast and the range of variation is large, its turbocharger has higher requirements. The electronic injection system has been widely used in modern car engines. With the combination of electronic control technology and new materials, the application of turbochargers on gasoline engines will become more and more popular.
