Compared with self-priming cars, turbocharged cars have an important component, the turbocharger, which will increase the air intake and increase the power. However, the price of the supercharger is more expensive, and the repair cost is very high once it is damaged, and our maintenance and the way we use the car largely determine its life. Therefore, when driving a turbocharged car, the following 4 things cannot be done, otherwise the supercharger will be damaged in advance.
1. Let's start with maintenance, don't add oil that doesn't meet the standards. The speed of the turbocharger can reach 100,000 revolutions per minute, and some even up to 200,000 revolutions, which is quite high, so it needs to have a very good lubrication condition. If the oil is not up to standard, the lubrication conditions are not met, and the life will inevitably be greatly reduced. Even at such a low engine speed, if you add a bad quality oil, it will cause wear and tear, not to mention such a high speed of the supercharger. For example, if the manufacturer requires SN5W-30 fully synthetic engine oil, you can not use SJ, 5W-20, or semi-synthetic or ordinary mineral oil, but use the same engine oil as the standard model and the manufacturer. For the choice of engine oil, it is best not to be greedy for cheap, it is best to use common big brand engine oil.
2. Unqualified air filters cannot be used and cannot be replaced extendically. Some old drivers don't care so much about the replacement of the air filter, thinking that it is not very useful, and the dirty spots are fine, originally changed once every 10,000 kilometers, and many people are replaced by 20,000 yuan. It does not have such a big impact on self-priming vehicles, and at most it increases carbon deposits. But for turbo vehicles, if the incoming air is not filtered well, it contains a lot of impurities, especially large particles of impurities, which will directly affect the life of the turbocharger. Because the incoming air must be compressed by the turbocharger before it can reach the cylinder, because of its high speed, if there are impurities and particles, it will damage the impeller, destroy its dynamic balance, and cause the bearing to accelerate wear, and even break down in a short time.
3. When it comes to using the car, you can't refuel the car when it's cold, and you should warm up the car when it's cold. When the temperature is low, the oil temperature is low and the fluidity is poor, and the lubrication effect cannot be optimal. If you refuel the turbocharger at full capacity without heating it up at this time, it will accelerate its wear. Warm up the car for 1 minute before driving, then drive at a low speed for a short while, and then refuel when the water temperature starts to rise. So if you go out and get on the highway, then it will be a little hotter.
4. Do not turn off the engine immediately after running at high speed. When the vehicle is driving on the highway, it is not possible to turn off the engine immediately after stopping, and it needs to idle for about 1 minute, so that the supercharger can be naturally cooled for a short time, which is more conducive to prolonging its life. If you have been driving at high speed and low speed for a period of time, you can turn off the engine immediately, or you can stop the engine immediately if you have been driving in the urban area, which is not considered a high-speed driving condition. In addition, refueling needs to add gasoline that meets the label, for example, the manufacturer requires the use of 95 gasoline, and must not reduce the label to add 92 without permission, because it will cause detonation and increase cylinder wear. Try to go to a larger gas station and don't add gasoline from unknown sources.
