The turbocharger uses the inertial impulse of exhaust gas discharged from the engine to push the turbine in the turbine chamber, and the turbine drives the coaxial impeller. The impeller presses the air sent from the air filter pipe to pressurize it into the cylinder. Therefore, turbochargers are normally used to increase engine power and reduce exhaust emissions. However, due to improper use, maintenance and maintenance, it is prone to malfunctions and may cause the engine to fail to work normally. All parts of this product are prepared for common failures of turbochargers.
