Turbocharger System: Turbocharger: Description
The turbocharger is a performance part and must not be tampered with. The actuator bracket is an integral part of the turbocharger. Tampering with the actuator or other 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 used on this vehicle is of the variable turbine type. These turbochargers use the entire exhaust energy to boost efficiency of the turbocharger and the engine.
The turbocharger is liquid cooled as well as oil cooled for better heat reduction.
The advantages of a turbocharger with variable turbine geometry are:
- Higher charge pressure already in the lower and in upper engine speed ranges.
- Higher torque as a result of improved cylinder charge.
- Reduction in exhaust emissions as a result of an improvement in the air supply of the engine.
- Increased power output as a result of the higher charge pressure combined with a reduced exhaust back pressure and thus improved charge cycle.
