Car Engine Components Quiz

What is the primary function of a piston in a car engine?

• To ignite the fuel-air mixture

• To convert chemical energy into mechanical energy

• To open and close the intake and exhaust valves

• To circulate the engine oil

Which component is responsible for converting the linear motion of pistons into rotational motion?

• Camshaft

• Crankshaft

• Spark plug

• Engine block

What is the role of a camshaft in a car engine?

• To provide the spark for igniting the fuel-air mixture

• To convert rotational motion into linear motion

• To control the opening and closing of the engine's valves

• To pump oil throughout the engine

What does a spark plug do in a car engine?

• Converts chemical energy into mechanical energy

• Controls the flow of coolant

• Ignites the fuel-air mixture in the combustion chamber

• Measures the amount of oxygen in the exhaust gases

What is the engine block primarily responsible for?

• Igniting the fuel-air mixture

• Housing the crankshaft and camshaft

• Filtering the engine oil

• Cooling the engine

Which component is directly involved in the compression of the fuel-air mixture before ignition?

• Crankshaft

• Camshaft

• Spark plug

• Piston

The crankshaft is located in which part of the engine?

• At the top of the engine block

• Inside the transmission

• At the bottom of the engine block

• Attached to the camshaft

What material is most commonly used to manufacture engine blocks?

• Plastic

• Aluminum

• Steel

• Cast iron

How does the camshaft receive its rotational motion?

• Directly from the spark plug

• From the piston's linear motion

• Through a belt or chain connected to the crankshaft

• It rotates independently based on the engine's speed

Which of the following is NOT a function of the engine block?

• To serve as the main structure for the engine

• To provide passages for coolant and oil

• To ignite the fuel-air mixture

• To support the crankshaft and camshaft
