Waste Gate
A waste gate is a component within a turbocharged engine system that controls the amount of exhaust gas directed to the turbocharger's turbine. By regulating exhaust flow, the waste gate limits the supercharging of the intake system and prevents the engine from exceeding its maximum manifold pressure.
Key Points
- •Waste gates can be fixed, manual, or fully automatic.
- •They control turbine speed by bypassing exhaust gases away from the turbocharger.
- •A waste gate malfunction can result in over-boosting the engine.
Exam Relevance
Important for understanding how turbocharger output is controlled and what actions a pilot must take if engine limits are exceeded due to supercharging anomalies.
