What purpose does a head gasket serve?
The (a) motion of the piston and connecting rod cause the crankshaft to rotate.
This component circulates a fluid.
Oil Pump
Gauze filter
Radiator
Which valve is bigger?
Inlet valve
Exhaust Valve
Neither
A benefit of having a larger inlet valve face is that it enables more fuel and (a) to enter the engine, resulting in more power.
Identify the 2 components
Timing gear
Shaft
Timing Belt
Pulley
Cam gear

Induction, ......................................, ....................................., Exhaust
(a)
What 2 actions occur during the induction stroke?
Fuel and Air enters the chamber
Inlet valve closes
Piston moves upward
Exhaust valve opens
What 2 actions occur during the compression stroke?
Both valves are closed
Piston moves to BDC
The piston moves to TDC squeezing the mixture
A spark occurs from the plug
What 2 actions occur during the power stroke?
The exhaust valve opens letting out burnt gas
The piston slams downwards
The piston slams upwards
A spark occurs from the spark plug, igniting the mixture
What 2 actions occur during the exhaust stroke?
Exhaust valve opens
The piston moves upwards, forcing out the burnt gasses
The piston moves downward and causes more fuel to enter
Inlet valve opens letting in more fuel
During which 2 strokes do valve overlap occur?
Induction
Compression
Power
Exhaust

In order for one cycle of the 4-stroke cycle to occur, the crankshaft will rotate (a) degrees.
In order for one cycle of the 4-stroke cycle to occur, the camshaft will rotate (a) degrees.
How is the crank to cam ratio achieved?
Via the engine layout
Via the timing belt
Due to the inertia of the flywheel
Due to the crank gear being twice as big as the cam gear
