The function of an exhaust turbocharger is to increase engine power. Insufficient intake after damage, low combustion chamber pressure, incomplete diesel combustion, resulting in a decrease in engine crankshaft speed and weakened output force.

The force of crankshaft rotation is transmitted to the flywheel, which is connected to the elastic plate and cover wheel of the torque converter, and the cover wheel is also connected to the pump wheel and transfer gear. The transfer gear controls the steering pump drive shaft, hydraulic pump, and variable speed pump drive shaft, so damage to the turbocharger can affect the overall weakness of the machine.

Its structure is very simple, but its design is very precise. The exhaust gas emitted by the engine enters two holes in the green circle, pushing the turbine blades in the yellow circle to rotate, while also driving the compressor blades in the purple circle to rotate at high speed. They share a common shaft, and the turbocharger begins to work.

The high-speed rotating compressor compresses the air after the filter into the intake pipe. When the intake valve opens, the intake volume in the combustion chamber increases, and the diesel atomized by the fuel injector burns more completely, thereby improving the engine's power.

Remove the fixed bolt 10 wrench from the compressor casing and use a small hammer to open it. After knocking, you can see the compressor impeller and orange O-ring. The turbine casing fixing bolt 13 wrench is prone to rusting after cooling due to the heat generated by high-temperature exhaust gas, which can easily bite.

The turbocharger turbine blades rotate at high speed, requiring oil to lubricate the internal bearings and extend their service life.

Oil enters the upper hole from the engine pressure pipe joint, lubricates the internal floating bearing and shaft, and then returns to the oil pan from the lower hole. When installing a new turbocharger, the oil inlet hole must be filled with oil.
