How to use the correct method to maintain and maintain the turbocharger, so that your car can be used for a few more years!

We need to follow the following approach:

1. After you start up, you should not press the accelerator pedal sharply, but should first idle for three minute

This is to increase the temperature of the engine oil and improve the oil flow performance, so that the oil through the oil pipe is transported to the turbocharger for sufficient lubrication,

"Then you can increase the engine speed and start driving, which is particularly important in winter. It takes at least 5 minutes to warm up the vehicle, otherwise the engine oil cannot fully lubricate the turbocharger. If you step on the accelerator and the engine oil is not in place, it can cause damage to the turbine bearings and wear.".

2.You can't turn off the engine immediately after running on the highway

Because after the engine is driven at high speed, a portion of the oil is supplied to the rotor bearings of the turbocharger for lubrication and cooling,

If the engine suddenly stalls and the oil pressure rapidly drops to zero, the oil lubrication will be interrupted,

The heat inside the turbocharger cannot be taken away by the engine oil, and the high temperature in the turbine part of the turbocharger will be transmitted to the middle,

The oil line is over there in red

The heat in the bearing support housing cannot be quickly taken away while the supercharger rotor is still rotating at high speed under the inertial action,

If it is not available, timely heat dissipation can result in "seizure" between the turbocharger shaft and shaft sleeve, which can damage the bearings and shafts. In addition, after the engine suddenly shuts down, the temperature of the exhaust manifold is very high at this time, and the heat will be absorbed into the turbocharger housing, boiling the oil remaining inside the booster into carbon deposits. When this carbon deposits more and more, it will block the turbine oil inlet, resulting in a lack of oil in the shaft sleeve, Accelerate wear between the turbine shaft and shaft sleeve.

So turn off the air conditioning before returning from high speed running, idle for three minutes, reduce the speed and temperature of the turbocharger to normal temperature, and then turn off the engine. Also, go outside the front of the car to see if the electronic fan is running. If it is not running, it indicates that the temperature is normal.

Also, it is very important that a turbo car should not idle in place for a long time. Generally, it should be kept at less than 10 minutes. If there is a severe traffic jam on the road, slowly apply the throttle every five minutes when shifting to neutral to allow more oil to be supplied to the turbine for lubrication. Otherwise, the turbocharger will also have poor lubrication, poor heat dissipation, and increased wear. Over time, because you do not fill the throttle, the flow pressure of the oil is low, Insufficient oil supply to the turbine is also not feasible, which can accelerate wear and damage.

3. Be careful when selecting oil

Based on the fact that the engine must withstand various pressures of turbocharging, the blood of the engine, that is, engine oil, must have good wear resistance, high temperature resistance, shear resistance, and explosion resistance. Establish a lubricating oil module to improve the strength and stability of the oil film.

"We must choose genuine engine oil, preferably synthetic or fully synthetic, and must adhere to the viscosity specified by the manufacturer. The engine oil must be better, and it is best to replace it in advance, without delaying the replacement.".

If you don't know what kind of oil your car uses, you can read the maintenance manual, ask the 4S store, or write down your model, model year, and displacement version. I can tell you, don't listen to people outside saying that the oil is expensive or good, and you can trust them, as this can harm your car.

4. Pay attention when performing oil maintenance

The air filter must be kept clean because if there is sand or debris entering, the turbine's high rotational speed and high pressure can easily damage the turbine's impeller.

If the vehicle's environmental conditions are poor, it is best to replace the engine oil with a new air filter every time. The quality of the air filter should be better. If the environment is not that bad, it can be replaced once after two to three maintenance sessions. Each maintenance session can be disassembled to blow away dust and sediment, preventing impurities such as dust from entering the high-speed rotating compressor impeller, causing unstable turbine speed or increased wear of the shaft sleeve and seals. It is also necessary to maintain good viscosity and fluidity of the engine oil, Because the fit clearance between the turbocharger's shaft and shaft sleeve is very small, if the lubricating capacity of the oil decreases, it will lead to premature scrapping of the turbocharger.

5. It is necessary to frequently check whether the sealing ring of the turbocharger is sealed.

"If the sealing ring is not sealed, the exhaust gas will enter the engine lubrication system through the sealing ring, contaminating the oil, and rapidly increasing the crankcase pressure. In addition, when the engine is running at low speed, the oil will also be discharged from the exhaust pipe through the sealing ring or enter the combustion chamber for combustion, resulting in excessive consumption of the oil and a situation of" burning oil. "".

6. Turbochargers should always be checked for abnormal noises or unusual vibrations, and for leaks in the lubricating oil pipes and joints.

7 Check the operation of the turbocharger

Before driving out and after parking, open the engine cover and check the connection part of the intake pipe to prevent looseness and falling off, which may cause the turbocharger to fail or air short circuit and directly enter the cylinder.

Check whether the turbocharger has oil or gas leakage, and whether the turbocharger housing has overheating, discoloration, cracks, and other phenomena.

Summary of turbocharger maintenance methods

1. The car won't leave until it's hot

2. Do not slam the accelerator, refuse to drive violently, and seriously damage the turbine

1. Unable to shut down the engine immediately after running at high speed, idling for 3 minutes
2. Genuine engine oil with appropriate viscosity and better quality

5. Frequently change the engine oil, oil filter, and air filter

6. Do not arbitrarily add maintenance products, clean the turbocharger, or use unknown additives. The more you use those products, the more likely they are to damage the turbocharger and engine. Do not easily trust others
