Many cars running on the street today are marked with a "T" at the end. This is the increasingly popular cars with turbocharged engines. The biggest advantage of turbocharging is that it can greatly increase the engine power and torque without increasing the engine displacement. When an engine is equipped with a turbocharger, its maximum output power can be increased by approximately 40% or more compared to that without a supercharger. In addition, the fuel consumption of the turbocharged engine is also lower than that of the naturally aspirated engine with the same power output. The advantages of these two aspects are destined to be favored by more and more people, but compared to the naturally aspirated engine, Turbocharged engines are more hypocritical, and require more stringent requirements on the working environment and maintenance. If they are not properly used and maintained, not only will the turbocharging effect not be well utilized, but the turbocharger's failure rate will be increased. Let me talk about some areas that require special attention for turbocharged engines.
Can't leave the car
After the engine is started, especially in winter, it should be allowed to run at idle speed for a period of time to allow the lubricant to fully lubricate the bearings before the supercharger rotor runs at high speed. Therefore, the throttle must not be blasted immediately after starting to prevent damage to the turbocharger oil seal.
Can't turn off immediately
After the engine has been running at high speed for a long time, it should run at idle speed for 3 to 5 minutes before turning off. When the engine is working, a part of the oil is supplied to the turbocharger rotor bearings for lubrication and cooling. After the engine is stopped suddenly, the oil pressure quickly drops to zero, the high temperature of the turbocharger turbine part is transferred to the middle, and the heat in the bearing support shell cannot be quickly taken away, while the supercharger rotor still rotates at high speed under the action of inertia Therefore, if the engine is shut down suddenly when the engine is hot, it will cause the oil remaining in the turbocharger to overheat and damage the bearings and shafts. In particular, it is necessary to prevent a sudden flameout after a few feet of throttle.
Keep clean
Clean the air filter on time to prevent dust and other impurities from entering the high-speed rotating air impeller, causing unstable speed or increased wear of the sleeve and seals. The engine oil and filter must be kept clean to prevent impurities from entering, otherwise the lubricating capacity of the engine oil will be reduced, resulting in premature scrapping of the turbocharger.
When disassembling the supercharger, keep it clean. Each pipe joint must be blocked with a clean cloth to prevent debris from falling into the supercharger and damaging the rotor. Because the supercharger is often operated at high temperature, its lubricating oil pipeline is subject to high temperature, and the internal oil is likely to be partially coked, which will cause insufficient lubrication of the supercharger bearing and damage. Therefore, the lubricating oil pipeline must be cleaned after a period of operation.
