[0002] A turbocharger is an air compressor that increases the air intake by compressing air. It uses the inertial force of the exhaust gas discharged by the engine to drive the turbine in the turbine chamber. The turbine in turn drives the coaxial impeller, which presses the air sent from the air filter duct to enter the cylinder at a higher pressure. When assembling the turbocharger, you need to first position the lower part of the turbocharger housing, then install the parts, and finally install the upper part of the turbocharger housing. During the assembly process, you need to use a fixing tool to fix the turbocharger housing.
