Check the misunderstandings of turbocharged vehicles, do not change the oil at will

Turbocharging is a familiar term for every car fan. In this era of soaring gasoline prices, turbocharging technology is also contributing to better engine efficiency and energy saving. Today, the reporter will deconstruct every detail of the car with a turbocharged engine in terms of use skills. In fact, as long as it is maintained on time, avoiding some car misunderstandings, the use of models with "T" is also very simple.

Misunderstanding 1. Change oil at will

Case: The car that Mr. Chen bought is a T model, and it has been three years. After the maintenance period of the vehicle in the middle of last year, in order to save costs, he used a bottle of non-synthetic engine oil that will be expired by a friend. Afterwards, the engine oil produced by a small manufacturer was used for two consecutive maintenances. Recently, he found that the vehicle started to shake slightly, and the engine also overheated after running a long distance last week.

Analysis: In terms of "drinking" engine oil, the turbocharger is indeed more "squishy". In addition to being larger than the ordinary naturally aspirated engine, the requirements for oil products are also higher. Because the design of the turbocharger is different from the naturally aspirated engine, the main shaft adopts a floating design. The turbine body and the main shaft are filled with oil. The entire main shaft relies on lubricating oil for heat dissipation and lubrication, while the poor quality oil is thick The degree is high, the liquidity is poor, and it cannot function well. It is recommended that the vehicle owner increase some investment in this area and replace the vehicle with fully synthetic motor oil.

Misunderstanding 2: Turn off immediately at the destination

Case: Miss Li's temperament has always been hot, and is a typical professional woman, which is why she bought T models. Because of her work, Miss Li often drove on business trips, and every time she arrived at her destination, because she was too tired, she immediately turned off and got off the car to move her muscles, leaving no room for the vehicle to breathe.

Analysis: After the engine has been running under high load for a long time, the owner must idle for a few minutes before turning off the engine, so that the machine parts can be effectively cooled and lubricated. The behavior of Ms. Li's use of the vehicle will often cause the vehicle to be idling at high speed. The problem is the same as sudden acceleration, which will damage the bearing of the vehicle.

Misunderstanding 3: Throttle on start

Case: Xiao Sun bought the T model in order to get more surging power. His home is only more than ten kilometers away from the company, but the road is wide and there are not many cars. He pursues "the distance between home and company is only 10 minutes", that is, the time from going out, starting, and stopping is controlled within 10 minutes, so the vehicle blasts the throttle every time it starts. After four months of "torture", it was found that the bearings of the vehicle had been damaged to a certain extent during maintenance.

Analysis: The ability to increase speed in a short period of time is a major feature of turbocharged cars, but this does not mean that owners can treat their cars rudely. In fact, blasting the throttle just after startup is easy to damage the turbocharger oil seal. The turbocharged engine has a high number of revolutions. After starting the vehicle, you cannot slam on the accelerator pedal. You should run it at idle speed for 3-5 minutes to allow the oil pump enough time to deliver the oil to all parts of the turbocharger. After the temperature rises slowly, the fluidity is better.
