What can cause a car's turbocharger to lose power?
1.It is not necessary to use full synthetic oil for turbocharged engines with inferior oil, but it is strongly recommended to use full synthetic oil. Full synthetic oil can obtain relatively high shear resistance with relatively low viscosity. As we all know, oil viscosity is low and resistance is small. , the fluidity is fast, and the high temperature of the turbocharger requires high-efficiency heat dissipation. The low viscosity of the fully synthetic oil can improve the heat dissipation efficiency of the oil, which is of great significance to the turbocharger.
2. Big foot throttle when the engine is cold and the car is low temperature
When the engine is low temperature, the accelerator accelerates rapidly, resulting in a rapid increase in the speed of the turbocharger. Although the engine is low temperature, the temperature of the exhaust gas is not necessarily low, which causes the turbo to rotate at a high speed and the temperature of the turbocharger rises sharply because the oil temperature is low. , poor circulation, the temperature is too late to reduce, resulting in ablation of the turbocharger.
3. The quality of the air filter element is poor. Many people like to blow the air filter with high-pressure air and continue to use it. This is very wrong. After the high-pressure air is blown through, the hole of the air filter element increases, resulting in large dust or sand particles. It may pass through the filter element, which is like a bird on a plane for a high-speed rotating turbine, which will cause damage to the turbine blades, resulting in the destruction of the dynamic balance of the turbine, resulting in eccentric wear and then damage.
4. Use inferior oil filter
Due to the small filtering area of many inferior filter elements, after long-term use, impurities will accumulate and the flow rate will be seriously reduced. At this time, the bypass valve of the oil filter will be opened, the oil filter element will lose its filtering effect, and a large amount of impurities will enter the engine cycle. These impurities After entering the turbocharger, the pipeline will be blocked, resulting in poor oil circulation of the turbocharger and wear of the floating bearing.
5. It is necessary to delay shutting down the engine when driving intensely for a long time. Please note that what is said here is "intense driving", not long-distance driving. In fact, long-distance high-speed 120km/h driving is not considered intense driving, and intense driving refers to extreme speed. , speeding, driving on mountain roads, such road conditions and driving will lead to high temperature of the turbocharger. Although modern engines have an independent electronic delay cooling cycle program, the engine can continue to dissipate heat after the engine is turned off, but once the battery is depleted, the cycle is terminated. , then the low temperature and high temperature of the turbocharger cannot cause the oil to be carbonized due to the ultra-high temperature even if the cycle is reduced, resulting in turbine ablation.
