What is the first stroke of a four-stroke engine called?
Compression
Intake
Power
Exhaust
During which stroke of a four-stroke engine is fuel injected into the combustion chamber in a diesel engine?
Intake
Compression
Power
Exhaust
What is a unique feature of the two-stroke engine's operation compared to the four-stroke engine?
It completes a power cycle in two strokes.
It uses valves for air intake.
It has a separate oil reservoir.
It requires a carburetor to mix air and fuel.
Which of the following engine parts is typically not found in a two-stroke engine?
Spark plug
Piston
Camshaft
Crankshaft
In a four-stroke engine, what happens during the compression stroke?
The air-fuel mixture is ignited.
The exhaust gases are expelled.
The air-fuel mixture is drawn into the combustion chamber.
The air-fuel mixture is compressed.
How does the exhaust system in a two-stroke engine differ from that of a four-stroke engine?
It uses a simpler design without a catalytic converter.
It directly expels exhaust gases without going through an exhaust stroke.
It recycles exhaust gases back into the combustion chamber.
It has multiple exhaust ports for better efficiency.
What is the purpose of the spark plug in a small engine?
To compress the air-fuel mixture
To ignite the air-fuel mixture
To intake air into the combustion chamber
To expel exhaust gases
Which component is responsible for converting the linear motion of the piston into rotational motion in both two-stroke and four-stroke engines?
Camshaft
Crankshaft
Connecting rod
Cylinder head
In a two-stroke engine, how are the intake and exhaust processes accomplished?
Through separate intake and exhaust valves
Through the movement of the piston uncovering ports in the cylinder wall
Through a turbocharger
Through a dedicated pump
What is the main advantage of a four-stroke engine over a two-stroke engine?
Higher power output
Simpler construction
More efficient fuel consumption
Less maintenance required
