Engine Parts

What is the main function of the cylinder head in an engine?

• Seal the top of the cylinders and contain the combustion process within the cylinders

• Provide fuel to the engine

• Control the steering of the vehicle

• Regulate the temperature of the engine

What is the purpose of piston rings in an engine?

• To create a seal between the piston and the cylinder wall

• To improve tire traction

• To reduce engine noise

• To increase fuel efficiency

Which part of the engine converts the linear motion of the pistons into rotational motion?

• Crankshaft

• Camshaft

• Gearbox

• Flywheel

What is the role of the camshaft in an engine?

• Balances the engine's rotating assembly

• Monitors the engine's oil pressure

• Controls the opening and closing of engine valves

• Regulates the fuel injection timing

What components make up the valve train in an engine?

• radiator, water pump, thermostat

• spark plugs, pistons, crankshaft

• turbocharger, intercooler, wastegate

• camshafts, lifters, pushrods, rocker arms, valves

What is the engine block and what is its function?

• The engine block is a decorative cover for the engine components.

• The engine block is a safety feature designed to prevent engine overheating.

• The engine block is a detachable part of the engine that is not essential for its functioning.

• The engine block is the main component of an engine that houses the cylinders, crankshaft, and other internal components. Its function is to provide structural support, house the moving parts of the engine, and contain the combustion process within the cylinders.

How does the cylinder head contribute to the combustion process in an engine?

• The cylinder head contributes to the combustion process by regulating the air conditioning system in the engine.

• The cylinder head contributes to the combustion process by housing essential components like valves, spark plugs, and fuel injectors, enabling intake, compression, ignition, and exhaust phases.

• The cylinder head contributes to the combustion process by controlling the radio volume in the engine.

• The cylinder head contributes to the combustion process by adjusting the seat position in the engine.

Why are piston rings necessary in an engine?

• To create a seal between the piston and the cylinder wall

• To increase fuel efficiency

• To improve tire traction

• To reduce engine noise

Explain the difference between the crankshaft and camshaft in an engine.

• The crankshaft and camshaft are the same component in an engine.

• The crankshaft controls valve operation, while the camshaft converts linear motion to rotational motion.

• The camshaft converts linear motion to rotational motion, while the crankshaft controls valve operation.

• The crankshaft converts linear motion to rotational motion, while the camshaft controls valve operation.

What are the different types of valves found in the valve train of an engine?

• spark valves

• fuel valves

• intake valves, exhaust valves

• compression valves
