The supercharger is now standard on truck engines and is one of the engine's core components. I believe that many drivers have the experience of turbocharger damage. How to use the turbocharger correctly? What misunderstandings do they need to avoid?
â— What is the exhaust turbocharger?
Almost all of the trucks are equipped with an exhaust gas turbocharger. Simply put, it is an air compressor. It is the high-temperature and high-pressure exhaust gas generated by the combustion engine that propels the turbine, and then pushes the coaxially installed compression impeller, which will be compressed. The air is fed into the cylinder and the amount of intake air has been increased to make the combustion more fully, thereby increasing the power and torque of the engine and reducing the emission.
â— What to watch out for during use
The supercharger does not need to be maintained separately during normal use. However, when the supercharger is working, it is exposed to high temperatures of 600°C for a long time and high-speed rotation of tens of thousands of revolutions or more. Some problems need to be noticed in use.
1: You must not drive when you are cold
After the vehicle stops overnight, the oil will flow back into the oil pan due to gravity. After the engine is started, it must be idling for about a minute to allow the oil circulation to be established so that the supercharger floating bearing is fully lubricated and then started.
2: Do not turn off immediately after high-speed operation
Because the turbocharger operates at a very high speed, it shuts off immediately after stopping at high speed, and the oil supply suddenly interrupts. At this time, the supercharger is still rotating at a high speed, and the oil in the floating bearing is quickly dried out. Damage to floating bearings. The correct method is to idle at least one minute before stalling and then extinguish the flame to protect the supercharger's floating bearing.
3: The oil and filter can not be sloppy
Supercharged engine operating environment is relatively harsh, so the oil demand is relatively high, in the choice of oil when the best in accordance with the manufacturer's required viscosity and level to use the replacement. Not to mention the filter element, you must use the factory's products. If you use counterfeit filter elements, once impurities enter the turbocharger bearing cavity, it will cause damage to the supercharger's floating bearing. In severe cases, it will cause the rotor to lock up. The compressor is scrapped.
4: Air filter is also important
The air filter is also related to the turbocharger, because the turbocharger is generally a floating bearing structure. The seal of the bearing chamber mainly depends on the pressure difference between the two sides. If the air filter is not replaced in time, the intake vacuum degree will increase. At this time, the pressure difference between the two sides can not be established will lead to turbocharger string oil. In practice, the booster string oil is often the cause of this problem. Many of the boosters that the card readers replaced may be caused by air filter plugging or false air filter.
One thing that everyone is not willing to accept is that 90% of turbocharger damage is caused by problems in use. Turbocharger is a core component in the car, and the value is relatively high, and the bad one has to spend thousands. However, under the premise of correct use and maintenance, the supercharger can live the same life as the vehicle, so it is necessary to pay attention to these problems in use.
