1. What is the primary role of pistons in an internal combustion engine?
To regulate fuel flow
To open and close valves
To compress the air-fuel mixture and convert it to mechanical energy
To deliver electrical spark
2. Which component in an internal combustion engine converts linear motion into rotational motion?
Camshaft
Crankshaft
Flywheel
Timing belt
3. What function does the camshaft serve in an engine?
To rotate the crankshaft
To ignite the air-fuel mixture
To control the timing of the intake and exhaust valves
To fuel the engine
4. What role does the fuel pump play in the engine?
Ignites the fuel

Lubricates engine parts
5. What type of ignition system component is responsible for igniting the air-fuel mixture?
Distributor
Fuel injector
Spark plug
Camshaft
6. What happens during the compression stroke of a four-stroke engine cycle?
The piston moves down compressing the air-fuel mixture
The exhaust valve opens
The piston moves up compressing the air-fuel mixture
The spark plug ignites the mixture
7. Which component ensures engine components are properly lubricated?
Water pump
Fuel pump
Oil pump
Cooling fan
8. Which system in the engine helps maintain a safe operating temperature by removing excess heat?
Ignition system
Cooling system
Exhaust system
Lubrication system
9. What is the primary role of the exhaust valve?
To let air-fuel mixture in
To create a spark
To allow burnt gases to exit the combustion chamber
To control timing
10. What is a common problem caused by improper engine lubrication?
