Why does the turbocharger emit white smoke?
The common failure cause of white smoke caused by burning oil caused by turbocharger:
insufficient intake air, resulting in a vacuum inside the supercharger, the oil is drawn from the lubricating part to the socket, and the temperature of the socket is high, so the oil burns Phenomenon.
The solution is to check the intake duct to ensure smooth intake, and use a high-quality air filter to ensure sufficient intake.
A turbocharger is actually an air compressor that increases the amount of intake air by compressing it. It uses the inertial momentum of the exhaust gas discharged from the engine to push the turbine in the turbine chamber, and the turbine drives the coaxial impeller, which presses the air sent from the air filter pipeline to pressurize it into the cylinder.
When the engine speed increases, the exhaust gas discharge speed and the turbine speed also increase synchronously, the impeller compresses more air into the cylinder, and the increase in air pressure and density can burn more fuel, correspondingly increase the fuel amount and adjust the engine speed, It can increase the output power of the engine.
▲Keep clean
When disassembling the supercharger, keep it clean, and plug each pipe joint with a clean cloth to prevent debris from falling into the supercharger and damaging the rotor. During maintenance, care should be taken not to collide and damage the impeller. If the impeller needs to be replaced, it should be subjected to a dynamic balance test. After reassembly is complete, remove the blockage.
▲To be cleaned
Since the supercharger is often operated at high temperature, its lubricating oil pipeline is subject to high temperature, and the internal oil is prone to partial coking, which will cause insufficient lubrication of the supercharger bearing and damage. Therefore, the lubricating oil line should be cleaned after a period of operation.
▲Pay attention to maintenance
Before leaving the car and after closing the car, check the connection of each pipe in the air passage to prevent the supercharger from being loose and falling off, which will cause the supercharger to fail and the air to short-circuit into the cylinder.
It can be seen that after the engine is supercharged, the structure of the parts is strengthened. From the perspective of use and maintenance, it is necessary to strengthen the compulsory maintenance of the engine, and pay attention to the correct operation method.
