In recent years, the craze for turbocharged engines has continued to rise, and even many brands that used to focus on naturally aspirated engines have switched to turbocharged engines. Especially for some young people who have just bought a car, the power boost brought by turbocharging is undoubtedly an irresistible temptation. It is true that turbocharged engines have many advantages, but in the daily use process, it will also increase the cost of our cars. However, many people have many misunderstandings about the care and maintenance of turbocharged engines, and the following masters point out some of the mistakes. As long as you recognize these mistakes, I believe that turbo maintenance will be much easier.
The following four points are some of the common misunderstandings about turbo maintenance
1. Turbocharged engines cannot be used in congested roads
Many people think that the speed of the turbocharged engine in the congested section does not go up, which is not right, mainly to see how much speed the turbine will play a role, the early engine because the speed is relatively high to have a role, so there is this defect, now there is a great improvement, in 2000 RPM can play a role, and in the congested place, 2000 RPM is also fairly easy to achieve.
Error two, to add No. 97 (Beijing standard 95) gasoline
Many people think that turbocharged engines are more delicate, to increase the number of gasoline, in fact, this is unnecessary, in the instructions clearly write that turbocharged models can add 93 (Beijing standard 92) gasoline, what standard gasoline is determined according to the compression ratio of the engine, and is not the use of turbocharging technology.
3. Do not turn off the engine immediately after parking
This is the early situation, in the early days, the use of mechanical pumps to cool down, after the mechanical pump does not work, it can not effectively cool the turbine, now this problem is solved, the use of electronic pumps, after the cooling function still works, in addition to the improvement of technology, the temperature of the turbine on the road will not reach very high, there is no need to delay the flame out, in addition to running at high speed for a long time to pay attention.
Mistake four, winter start to take a long time to warm up
Many people think that the turbocharger is cooled by oil, the oil temperature is low in winter, can not lubricated the car, to increase the oil temperature for a long time, this is completely wrong, many experts explain that a long time hot car is not only no good for turbine maintenance, but also increase exhaust gas, hot car only needs about 2 minutes, when the speed reaches 1000, slow driving, When the water temperature and oil temperature reach normal, it can be fully driven.
In fact, if the car with a turbocharged engine is not properly used and maintained, the failure rate of the turbocharger will increase, and the turbocharged engine has some special attention compared with the ordinary engine in the use and maintenance. So what are the points to pay attention to? Here are five easy ones:
1: Clean the air filter on time to prevent dust and other impurities from entering the high-speed rotating compressor impeller, causing instability of the speed or worsening wear of the shaft sleeve and seals.
Two: The clearance between the shaft and the sleeve of the turbocharger is very small, so the engine oil and filter must be kept clean to prevent impurities from entering, otherwise the lubrication capacity of the oil will decline, resulting in the premature scrapping of the turbocharger.
Three: After the engine starts, you can not step on the accelerator pedal quickly, you should idle for 3 to 5 minutes, which is to increase the oil temperature, improve the flow performance, and make the turbocharger fully lubricated, and then you can improve the engine speed and start driving.
4. Always pay attention to the phenomenon that the turbocharger has no abnormal sound or increased vibration, and the lubricating oil pipes and joints shall not have leakage.
Five: The high-speed engine can not be suddenly turned off, otherwise the oil lubrication will be interrupted, and the heat inside the turbocharger can not be taken away by the oil, which is easy to cause the "bite" between the turbocharger shaft and the sleeve. The engine should be idled for about 3 minutes before turning off to reduce the speed of the turbocharger rotor. However, the turbocharged engine can not idle for a long time, otherwise the supercharger will also cause poor lubrication due to low oil pressure, and the idle time should not exceed 10 minutes.
