Questions about the high temperature of the turbochargerThe component is operated by a pressing strategy, and then it is pushed by an inherent force, but there is a problem that deserves our attention during the operation, that is, the high temperature problem of the supercharger, if abnormality occurs, it will be serious Affect the use of equipment. High temperature problem of turbocharger: The turbocharger rotor manufacturer introduces that the general high temperature mainly comes from the exhaust gas temperature. The exhaust gas temperature of a gasoline engine can reach 750 to 900 degrees at full load, and it is nearly 700 degrees under normal working conditions. These exhaust gases will cool down when they push the turbine to rotate. Where does this temperature go? It is absorbed by the turbine blades. Secondly, the rotating shaft connecting the turbine and the impeller rotates at a high speed of more than one hundred thousand revolutions, and the friction between the rotating shaft and the bearing will generate a lot of heat. After ^, the intake impeller continuously sucks in air, compresses the air, and its own temperature also rises. These factors add up to make the entire supercharger in the "hot".Turbine failure caused by high temperature is mainly due to the deformation and ablation of turbine blades and the failure of rotating shaft strain. Over the years, many people who know how to deal with this problem have come up with various methods. In general, there are nothing more than two: use more heat-resistant materials and Use more effective cooling methods. In order to prevent problems, it should be noted that after the engine is started, especially in winter, it should be left idling for a period of time so that the lubricating oil can fully lubricate the bearings before the turbocharger rotor runs at high speed. The throttle should not be blasted violently after starting to prevent damage to the turbocharger oil seal. After the engine is under heavy load and running for a long time, it should be idle for 3 to 5 minutes before stalling.
