Influence of booster system flow channel blockage factors one of the direct consequences of 

booster flow channel blockage is to increase the resistance of airflow in the system. If any link 

in the flow route is blocked, such as dirt, carbonization, deformation, etc., it will increase the back

pressure of the compressor due to the increase of flow resistance, reduce the flow rate, and cause

surge. Often, the blockage of the turbocharger's  GT17 812908-0003 5801461609  airflow channel 

is the main cause of its surge.

After a long time of running at high speed, the turbocharger engine cannot be turned off 

immediately. When the engine is working, a part of the oil is supplied to the turbocharger

rotor bearings for lubrication and cooling. After the sudden shutdown of the running engine, 

the oil pressure quickly drops to zero, the high temperature of the turbocharger turbine part is

transmitted to the middle, and the heat in the bearing support shell cannot be quickly taken 

away, while the supercharger rotor is still rotating at high speed under the action of inertia.

The turbocharger engine is by the fuel in the cylinder combustion to do work to produce power,

because the amount of fuel input is limited by the amount of air sucked into the cylinder, so the 

power generated by the engine will also be limited, if the engine operating performance has been 

in the best state, and then increase the output power can only increase the amount of fuel by

compressing more air into the cylinder, thereby improving the combustion to do functional force.

Therefore, under the current technical conditions, the turbocharger is the only mechanical device 

that can increase the output of the engine without changing the operating efficiency.
