Super/Turbo Chargers Flashcards
What 2 elements does a normally aspirated engine rely on to perform its function
- Atmospheric pressure
- “Sucking” of pistons
Sucking from pistons draws fuel/air mixture into the cylinder for combustion
What is the core function of a Super/Turbo charger
Force air into intake manifold under pressure
What is the key benefit of a super/turbo charger engine
MORE POWER at GREATER ALTITUDE
What is the definition of “over boosting”
Pressure EXCEEDS design limitations
Pressure from super/turbo charger exceeds the design limitation of the pressure allowed inside the intake manifold and cylinders
How do the following functions work;
- Super Charger
- Turbo Charger
What drives them
- Mechanical air pump drive by engine
- Air pump driven by hot exhaust gases from engine
Which engine type marries up to the below drive type
- Mechanical air pump driven by the engine
- Air pump driven by hot exhaust gases from the engine
- Super Charger
- Turbo Charger
What is exhaust gas temperature dependent on
FUEL/AIR MIXTURE
What is the TIT gauge
Turbo Inlet Temperature
When must attention be paid to the Turbo inlet Temperature
When LEANING a turbo charged engine
When leaning a turbo charged engine, what gauge should the pilot pay attention to
TURBO INLET TEMPERATURE
(TIT)
What is the function of an Automatic Waste Gate
Opens automatically
Prevent excessive intake manifold pressure
What actuates the Waste Gate position
ENGINE OIL PRESSURE
What happens to air flowing through the air intake in a turbo charged engine
COMPRESSED
Turbo charged engine
What is the purpose of exhaust gases being ducted through the exhaust exchange
TURN TURBINE to DRIVE COMPRESSOR
What are 3 typical failure categories in a super/turbo charged engine
- Waste Gate Failure
- Exhaust Failure
- Bearing Failure
