What is the main function of a piston in an engine?

• To cool down the engine.

• To provide electrical power to the vehicle.

• To transfer the force generated by the combustion of fuel to the crankshaft.

• To regulate the flow of fuel in the engine.

What is the purpose of a crankshaft in an engine?

• To reduce friction in the engine.

• To control the flow of fuel in the engine.

• To generate electricity for the engine.

• To convert reciprocating motion into rotational motion.

What is the role of a camshaft in an engine?

• The camshaft controls the transmission.

• The camshaft is responsible for generating electricity.

• The camshaft controls the valves.

• The camshaft regulates the fuel injection.

What is the function of an intake valve in an engine?

• Regulate the temperature of the engine

• Allow air and fuel mixture to enter the combustion chamber

• Ignite the air and fuel mixture

• Control the flow of exhaust gases

What is the purpose of an exhaust valve in an engine?

• To increase the engine's horsepower

• To supply fuel to the combustion chamber

• To cool down the engine

• To release burned gases from the combustion chamber

What is the main function of a connecting rod in an engine?

• To connect the piston to the camshaft and control valve timing.

• To provide support and stability to the engine block.

• To regulate the flow of coolant in the engine.

• To connect the piston to the crankshaft and convert reciprocating motion to rotational motion.

What is the role of a cylinder head in an engine?

• The role of a cylinder head in an engine is to seal the combustion chamber and house the valves, spark plugs, and fuel injectors.

• The role of a cylinder head in an engine is to generate electricity.

• The role of a cylinder head in an engine is to regulate the flow of coolant.

• The role of a cylinder head in an engine is to provide a cushion for the piston.

What is the function of a timing belt in an engine?

• The timing belt in an engine is designed to reduce engine noise and vibration.

• The timing belt in an engine is used to regulate the air intake into the combustion chamber.

• The function of a timing belt in an engine is to synchronize the rotation of the crankshaft and the camshaft.

• The timing belt in an engine is responsible for controlling the fuel injection timing.

What is the purpose of a fuel injector in an engine?

• To remove excess fuel from the combustion chamber

• To regulate the temperature of the engine

• To increase the air intake in the combustion chamber

• To deliver fuel into the combustion chamber

What is the main function of a spark plug in an engine?

• Ignite the air-fuel mixture

• Control the temperature of the engine

• Provide lubrication to the engine

• Filter the air entering the engine
