How to maintain the turbocharger?
Turbocharged engines have the unique advantage of taking into account both small displacement and high horsepower. With the requirements of emissions, the cars on the market are almost dominated by small-displacement turbocharged engines. There are always two things. On the other hand, another aspect of turbocharging is that it is more "delicate" than a self-priming engine. How to understand this delicacy, let's explain from the following points.
1. First of all in the choice of oil
Because the turbocharger and the engine share the lubrication system, the high speed and high temperature of the supercharger determine that the oil must have better wear resistance, lubricity, heat dissipation, and cleanliness. Therefore, fully synthetic oil with good comprehensive performance is the first choice, and at least high-quality semi-synthetic oil must be selected to meet the needs of the supercharger. Never choose fake oil or non-compliant oil, it will cause abnormal wear of the supercharger bearings, carbon formation, and shorten the service life of the supercharger.
2. Hit the accelerator before stopping
Depressing the accelerator pedal before stopping is the most harmful to the turbocharger. After slamming the accelerator, the rotor speed of the turbocharger is close to the upper limit speed. During this period of time, there is a lack of circulating lubrication. This approach will damage the supercharger in advance. Be sure to remember to stop after idling for a few minutes.
3. Throttle the accelerator after the cold car starts
Many car owners have this habit, that is, after starting the car, step on the accelerator to increase the speed to quickly warm up the engine. After starting the car, it takes a few seconds or even ten seconds for the oil to be injected into the supercharger through various oil passages. Intermediate, the supercharger bearing is lack of lubrication during this period, so in order to reduce abnormal wear, it is recommended to start the car at idle speed for more than 30 seconds before slowly increasing the speed to prolong the service life of the supercharger.
4. Stop immediately after high-speed operation with large load
After high-speed operation with a large load, the rotor speed of the engine supercharger is at the upper limit of the speed, and the temperature of the supercharger is also very high. At this time, it is not possible to turn off the flame immediately, which may cause abnormal wear of the bearing, and it takes a few minutes of idling to turn off the flame.
