TURBOCHARGER SYSTEM CHECK

HOW DOES TURBOCHARGER WORKS ?

High temperature, high pressure exhaust gases from the engine enter the turbine housing and drive the turbine wheel. The turbine wheel is connected to the compressor wheel with a solid shaft. The rotation of the compressor wheel compresses the ambient air and forces it into the engine. This increases the amount of fuel that can be burnt, increasing the efficiency and power output of the engine.

BENEFITS OF TURBOCHARGING

  • Increased power output of the engine
  • Engine power retained at altitude
  • Reduced engine size and weight
  • Reduced emissions
  • Reduced fuel consumption
  • Reduced cost of ownership
