How to maintain the turbocharger（Part 2）
3. The cold car should start slowly, and the hot car should be idling for a while before turning off
In the early stage of cold start, the oil temperature is usually low and viscous, and the lubrication effect is not good. It takes a process and time to warm up to the normal operating temperature. If you force the turbo to Working at full load will increase the wear of the turbine and shorten the life of the turbine.
The correct way to use it is: in the first few minutes of driving, you should run slowly for a few minutes. After the oil is in the best state, step on the accelerator to let the engine run at a high speed, especially in the winter in the north, you must pay attention to the cold start. Let the car warm up before you go, it is comfortable and you are comfortable.
When parking, because the temperature of the turbine is very high, it is best to idle for a while and then turn off the car after parking. At this time, the oil system and cooling system of the engine are still working, which can make the temperature of the turbine a little bit. It should be noted that the turbine will continue to run due to inertia after the car is turned off. At this time, oil lubrication is still required. If you suddenly turn off the engine, the entire engine system will no longer work. The cooling system of the turbine and The lubricating oil supply will suddenly stop, and only natural cooling can be used, which will lead to a sharp reduction in the life of the turbine.
In addition, there are new turbocharged engines that have solved the problem of turbo cooling after parking by supercharging the additional cooling system water pump control valve, but it should be noted that when you turn off the engine, the oil system still does not work, and the lubrication of the turbo The effect is reduced, so we recommend that models with a turbo engine should be able to idle for a while before killing the car.
4. Regular inspections are important
It is the same as the regular examination of the human body. Develop this good habit can help us to find out the trouble of the turbine in time and prevent it from happening. For example; check the appearance of the turbocharger for damage to each sealing ring, the oil inlet pipe and oil return pipe joints for looseness and signs of oil leakage, whether there is residual organic oil in the exhaust outlet of the supercharger, and the compressor intake straight Whether there is oil in the pipe wall, and whether the turbocharger has abnormal noise or abnormal vibration.
Summarize:
In fact, turbocharged engines need to pay special attention to two points in normal use. One is to use better oil as much as possible, and this also leads to the maintenance cost of turbo engines is much higher than that of ordinary naturally aspirated engines; One point is that in daily use, you should pay attention to warming up the car before driving, and it is best not to turn off the engine immediately when parking. As long as we pay attention to the above two points, we can fully enjoy the smooth power brought by the turbocharged engine.
