Turbocharger - Description

DESCRIPTION










CAUTION: The turbocharger is a performance part and must not be tampered with. The wastegate bracket is an integral part of the turbocharger. Tampering with the wastegate components can reduce durability by increasing cylinder pressure and thermal loading due to incorrect inlet and exhaust manifold pressure. Poor fuel economy and failure to meet regulatory emissions laws may result. Increasing the turbocharger boost WILL NOT increase engine power.

The turbocharger (1) is an exhaust-driven supercharger which increases the pressure and density of the air entering the engine. With the increase of air entering the engine, more fuel can be injected into the cylinders, which creates more power during combustion.










The turbocharger assembly (1) consists of four major component systems :

- Turbine section
- Compressor section
- Bearing housing
- Wastegate

Wastegate
The turbocharger uses a wastegate to regulate the amount of the intake air entering the engine. The wastegate is controlled by the wastegate actuator on the turbocharger. When the wastegate valve is closed, all of the exhaust gases flow through the turbine wheel inside the turbocharger. As the intake manifold pressure increases, the wastegate actuator opens the valve, diverting some of the exhaust gases away from the turbine wheel. The wastegate actuator is part of the turbocharger and is not serviced separately.
