In this era of pursuit of efficiency, turbocharging has become a symbol of efficiency and technology.publicIt was the first to introduce TSI technology in the Chinese market, and successively launched three engines of 1.4T, 1.8T, and 2.0T. Then GM's Turbo technology was also introduced to China and applied to the new Regal, the new LaCrosse, Yinglang and other models. Compared with naturally aspirated engines, turbocharged engines have stronger power. Advanced turbocharged engine technology allows gasoline to burn more fully by improving the air quality entering the combustion chamber, thereby increasing output power. However, while the turbocharged engine increases the output power, the maximum burst pressure and average temperature generated during operation are also greatly increased. Therefore, the turbocharged engine also puts forward higher requirements for car owners in terms of maintenance. How should turbocharged engines be maintained and used? In this issue, the "Car 114" column specially prepares the maintenance tips for Turbo and TSI models for everyone, and provides car owners with caring care.
Choose high-grade fully synthetic engine oil
Mr. Che Zhongyuan: At the beginning of this year, I bought a new Regal 2.0T model, but every time I maintain it, the after-sales staff at the 4S shop suggested that I change to a higher-priced high-end synthetic engine oil, and my friends told me to use ordinary Engine oil is fine. I want to consult an expert, what kind of oil should be used for turbocharged models? What kind of harm does the use of ordinary engine oil cause to the engine?

Expert visits: According to "Buick Care" after-sales service experts, at present, most turbochargersSuperchargerMost of the problems that occur are due to the gap between the turbocharger and the intake pipeOil sealThe seal is damaged, causing a large scale
Die-burning engine oil. The main reason for the damage of the oil seal is that the oil replacement cycle is too long or the use of inferior oil, which causes the floating turbine main shaft to lack lubrication and heat dissipation, which damages the oil seal and causes oil leakage.General turbocharger in the engineRotating speedIt will only start when it reaches 3500 rpm, and it will increase rapidly until 6000 rpm. The higher the engine speed, the stronger the shear resistance of the oil is required, which is to allow the oil to resist the shearing effect and keep the viscosity stable. Only in this way can the lubricating ability of the oil not decrease at high speeds.
Experts remind car owners that when choosing engine oil, they should choose high-grade fully synthetic engine oil. Ordinary mineral oil is not suitable for turbocharged engines.
Clean the turbocharger regularly
Owner Mr. Ma: My car is a 1.6T Yinglang. I heard from friends around me that turbocharged engines have very high environmental requirements for driving, especially in areas with poor ambient air cleanliness and high dust content. Try not to use turbines. Supercharge, I want to consult an expert, is this statement correct?
Expert visit: the biggest feature of turbine engine
It is high power, which depends on its precise design and manufacturing process, and also determines its harsh working environment.Therefore, it islubricating oilThe requirements for cleaning and protection of the turbocharger are very high, and any impurities will cause great frictional damage to the components, so it is necessary to keep the turbocharger clean.
In actual use, the after-sales service experts of "Buick Care" advise the car owner, first of all, the engine oil andFilterMust be kept clean and prevent
Prevent impurities from entering.Because the matching clearance between the rotating shaft of the turbocharger and the shaft sleeve is very small, if the lubricating ability of the oil decreases, the turbocharger will be scrapped prematurely; secondly, it needs to be cleaned or replaced on timeair filter, To prevent dust and other impurities from entering the high-speed rotating turbocharger impeller; finally, experts also remind the car owner that if the surrounding air is poorly clean and the dust content is high, do not use turbocharger for a long time.
Start gently and don't turn off the fire immediately
Owner Ms. Huang: I’m a novice. I just bought a 1.4T Golf. When I went out in the recent morning, I found that many car owners in the community were hot cars. I would like to consult an expert about whether turbocharged models need hot cars. ?
