What links each piston to the engine's crankshaft?
piston ring |
|
cylinder arm |
|
halfshaft |
|
connecting rod |
A connecting rod employs a wrist pin to link each piston to the engine's crankshaft.
What is the function of the head gasket?
to seal the engine block from the cylinders |
|
to seal the brake assembly from external contaminants |
|
to seal the exhaust system from the drive train |
|
to connect the transmission to the drive train |
A head gasket is a gasket that sits between the engine block and cylinder heads to seal the cylinders to ensure maximum compression and avoid leakage of coolant or engine oil into the cylinders.
The air-fuel mixture is delivered to the combustion chamber by a(n):
fuel valve |
|
intake valve |
|
exhaust valve |
|
air valve |
The combustion chamber is located in the cylinder head and contains the combustion of the air-fuel mixture. This mixture is delivered by an intake valve and the waste gases from combustion are removed from the combustion chamber by the exhaust valve.
Waste gases from combustion are removed from the combustion chamber by the:
piston |
|
camshaft |
|
exhaust valve |
|
head gasket |
The combustion chamber is located in the cylinder head and contains the combustion of the air-fuel mixture. This mixture is delivered by an intake valve and the waste gases from combustion are removed from the combustion chamber by the exhaust valve.
Which of the following maintains pressure in the cooling system?
radiator cap |
|
water jacket |
|
water pump |
|
thermostat |
The radiator is responsible for tranferring heat from the coolant to the outside air. Radiator hoses transfer coolant to and from the engine to the radiator and a radiator cap maintains pressure in the cooling system to increase the boiling point of the coolant mixture and thus allow it to absorb more heat.
