How Turbos Work

Turbo charging forces compressed air into an engine to improve a vehicle’s performance. With turbochargers, a smaller, more fuel efficient engine can replace a larger, less fuel efficient engine. The smaller engine achieves similar performance, while reducing exhaust emissions.

The turbocharger is driven by waste exhaust gases forced through an exhaust housing onto a turbine wheel. The turbine wheel is connected by a common shaft to a compressor wheel so that both wheels rotate simultaneously when the exhaust gases hit the turbine wheel. Rotation of the turbo assembly compresses the intake air routed through a compressor housing, forcing the compressed air into the engine’s cylinders. The increased amount of air forced into the engine creates more power than a similarly sized non-turbocharged engine and power similar to a larger, non-turbocharged engine. Turbochargers operate at very high temperatures, high speeds and high pressures. Optimum performance can only be achieved by the proper operation, maintenance and service.

Service Tips:

  • Change your engine oil at the recommended intervals.
  • Service your turbo at the recommended intervals.
  • Use only qualified and experienced specialists to service your turbo.
  • Check out any oil leaks, excessive or unusual noise and vibration as soon as they occur.
  • Lack of power, excessive noise, black or blue colored smoke are more likely to indicate engine problems than turbo problems.
  • Wait for the engine oil to reach normal operating temperature before revving the engine excessively.
  • Let the engine idle for a couple of minutes before switching the vehicle off.
