1. General
A. The turbocharger has two sides, a turbine side and a compressor side. Exhaust gas
continuously passes through the turbine side of the turbocharger and turns the turbine within
the turbocharger. The rotating turbine compresses air that flows through intake pipes on the
compressor side of the turbocharger. The air becomes pressurized and is discharged into the
inlet pipe to the air inlet housing (Figure 1). The exhaust gas is discharged through exhaust
outlet pipe attached to the turbocharger.
B. An exhaust bypass valve (Figure 1) at the exhaust transition at the rear of the engine controls
the amount of exhaust gas flow. This valve is controlled by an actuator. The actuator is
activated by a solenoid.
C. The EECS controls the amount of exhaust gases supplied to the turbine wheel and monitors
compressor outlet pressure from sea level to critical altitude.
2. 50-Hour Turbocharger Inspection
A. Examine all of the hoses and mounting brackets in the turbocharger system for damage,
leaks, tightness, and blockage. Identify and correct the cause of any leaks. Replace any
damaged gaskets or hoses.
