Internal Combustion Engine Components

What is one function of the cylinder head in an internal combustion engine?

• To convert force from expanding gas to the crankshaft

• To contain the upper surfaces of the combustion chamber

• To connect the piston to the crankshaft

• To control the timing and quantity of petrol/air mixture flow

What is the main material used to make the cylinder block of an internal combustion engine?

• Titanium

• Steel alloy

• Copper

• Aluminium alloy

What is the function of the crankshaft in an internal combustion engine?

• To move the wheels in a circular motion

• To convert reciprocating force of the piston to rotary motion

• To control the timing and quantity of petrol/air mixture flow

• To connect the piston to the crankshaft

What is the main purpose of the CAMSHAFT in an internal combustion engine?

• To control the timing and quantity of petrol/air mixture flow

• To convert force from expanding gas to the crankshaft

• To control the opening and closing of the valves

• To move the wheels in a circular motion

• Titanium

• Aluminium alloy

What is the function of the CONNECTING ROD in an internal combustion engine?

• To convert reciprocating motion into rotating motion

• To connect the piston to the crankshaft

• To convert force from expanding gas to the crankshaft

• To control the timing and quantity of petrol/air mixture flow

What is the main purpose of ENGINE VALVES in an internal combustion engine?

• To connect the piston to the crankshaft

• To allow gasses in and out of the engine

• To convert force from expanding gas to the crankshaft

• To move the wheels in a circular motion

What is the function of the ROCKER SHAFT and ROCKER ARMS in an internal combustion engine?

• To move the wheels in a circular motion

• To transmit the movement of the camshaft towards the intake and exhaust valves of the engine

• To convert reciprocating motion into rotating motion

What are engine MANIFOLDS used for in an internal combustion engine?

• To convert force from expanding gas to the crankshaft

• To control the timing and quantity of petrol/air mixture flow

• To connect the piston to the crankshaft

• To direct the flow of air or fuel mixture to the cylinders or to the exhaust pipe

How is the CYLINDER HEAD cooled in a large capacity internal combustion engine?

• By direct air flow

• By both water passages and fins

• By fins in an air-cooled engine

• By water passages (jackets) where coolant circulates
