Piston engines
The 4 strokes in a 4-stroke engine
Intake, compression, combustion, exhaust
This type of propeller does not change its pitch
Fixed-pitch
This intake system uses a float
Carburetor
This engine component allows the piston to push spent fuel-air mix out of the cylinder
Exhaust valve
This type of engine was designed for sitting low in race cars
Horizontally-opposed
This type of propeller can change its pitch
Constant-speed / Variable-pitch
This intake system injects a computer-set amount of fuel and air directly into each cylinder
Fuel-injection
What happens to the temperature when a Venturi vaporizes fuel
It gets colder
This is the only stroke that produces power
Combustion / Power
The pilot's control to change the propeller pitch
Propeller lever
Carburetors use this principle to draw in and vaporize fuel
Venturi
By adjusting the mix lever
The act of starting an engine without a starter motor
Hand-propping
What color is the propeller lever in a constant-speed aircraft
Blue
When flying in cold, humid air, a pilot should flip this switch
Carburetor heat
What does the propeller on a single-engine constant-speed plane do if the engine stops?
It turns to a flat pitch so it can still power electronics
This is what gets taken into and compressed by the piston
Fuel-air mix
The order of instruments a constant-speed prop pilot uses to speed up the plane
Propeller lever up, then throttle lever up
How does the use of carburetor heat impact airplane performance?
Carb heat decreases engine performance
Why a pilot looks at the tachometer in a fixed-pitch-propeller plane
To determine propeller RPM
