The working principle of the turbocharger is not complicated. In short, it is to drive the turbine through the exhaust gas emitted by the engine, and then drive the turbofan connected to it on the same connecting shaft through the turbine to turbocharger shaft continuously the engine cylinder. The fresh air is pressed inside, so that the more air the cylinder enters per unit time, the higher the working efficiency.
The turbocharger is a high-temperature component because the gas that drives it runs directly from the exhaust gas discharged from the cylinder, the temperature is as high as 900 ° C -1000 ° C, and under full load, the turbine speed can reach 180,000-20 per minute. Ten thousand turns. Turbines have to do such high speeds at such high temperatures, naturally requiring particularly efficient and stable lubrication conditions. Moreover, in the high temperature and high pressure environment, the various components of the supercharger and the lubricating oil must have good high temperature resistance and sealing, so we should start from the following aspects for its maintenance:
Many car owners don't know how to choose when changing oil. The damage of the turbocharger is generally caused by the seal seal between the oil and the intake pipe, resulting in large-scale burning of oil. The professional investigation found that a large part of the damage of the oil seal is because the owner did not change the oil on time, or used inferior oil, which caused the floating main shaft of the turbine to not properly lubricate and dissipate heat, thus damaging the oil seal at high temperature and causing oil leakage. .
Therefore, it is recommended that the turbocharged engine should choose high-quality oil with high temperature resistance and oxidation resistance, and pay attention to shortening the oil replacement period.
The fit clearance between the turbocharger shaft and the bushing is small, so if the oil used is not clean or if the oil filter is dirty, impurities will enter, which will cause excessive wear of the turbocharger. In addition, if the inhaled air contains a large amount of impurities, once the dust particles enter the high-speed supercharger impeller, the dust particles will hit the turbocharger impeller, resulting in unstable turbine operation, bushing and seal wear. Pay special attention to the timely replacement of the oil filter and air filter to keep the turbine clean.
The turbocharger system is divided into a single turbo system and a twin turbo system. Only one turbocharger booster system is a single turbocharger system. In addition to the turbocharger, the turbocharger system includes an intake bypass valve, turbocharger shaft an exhaust bypass valve, and an exhaust bypass valve control device.
A twin-turbocharged system with a six-cylinder gasoline injection engine. Two of the turbochargers are arranged side by side in the exhaust pipe, and the cylinders of 1, 2, and 3 are grouped as one group, and the 4, 5, and 6 cylinders are used as another group. A turbocharger.
Since the exhaust intervals of the three cylinders are equal, the supercharger rotates smoothly. In addition, grouping the three cylinders together also prevents exhaust interference between the cylinders. In addition to turbochargers, intake bypass valves, exhaust bypass valves, and exhaust bypass valve controls, the system includes intercoolers, resonant chambers, and boost pressure sensors.
The vehicle turbocharger consists of a centrifugal compressor, a radial turbine and an intermediate. The supercharger shaft is supported within the intermediate body by two floating bearings. The intermediate body has oil passages for lubricating and cooling bearings, as well as seals for preventing oil from leaking into the compressor or turbine.
