Turbocharger
A turbocharger is an exhaust-driven supercharging device used to increase the manifold pressure and density of the air supplied to the engine cylinders. By compressing the intake air, it allows the engine to maintain its power output at higher altitudes where the air is normally less dense.
Key Points
- •A turbocharger is driven by engine exhaust gases via a turbine, not mechanically by the engine.
- •It maintains or increases engine power output at higher altitudes.
- •Pilots must remain vigilant to avoid exceeding manifold pressure limits.
Exam Relevance
Candidates must understand the purpose of supercharging/turbocharging and the precautions required to avoid engine detonation and overboosting.
