Why supercharger is the most vulnerable assembly on Cummins engine? Because the rated working speed of the supercharger is more than 130,000 rpm, and it is at the outlet of the exhaust manifold, the temperature is extremely high (above 800°C), and the inlet and exhaust pressure is also large, high temperature, high pressure and high speed. Therefore, the requirements for lubrication, cooling and sealing of the supercharger are relatively high. In order to ensure the service life of the supercharger, it is necessary to ensure the lubrication and cooling of the turbocharger floating bearing. At the same time, in use, it is required to: a. The engine should idle for 3-5 minutes after starting. Do not add load immediately to ensure good lubrication of the supercharger. The main reason is that the supercharger is located at the top of the engine. If the supercharger starts to run at high speed immediately after the engine starts, it will cause the oil pressure to fail to rise i...
