1

The fluid reservoir stores the __________ that the master cylinder uses to maintain hydraulic pressure.

79% Answer Correctly

brake fluid

2

Another name for a reciprocating engine is a(n):

41% Answer Correctly

cylinder engine

internal combustion engine

piston engine

3

Which of the following maintains pressure in the cooling system?

61% Answer Correctly

water pump

water jacket

thermostat

radiator cap
Solution

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.

4

Which of the following is not a component in the engine lubrication system?

70% Answer Correctly

pickup tube

oil filter

differential

pressure relief valve
Solution

In engine lubrication, oil remains in the oil pan until the engine is turned on. It then gets sucked up the pickup tube by the oil pump and pressurized. This pressure is moderated by the pressure relief valve and the oil is fed through the oil filter into the engine to lubricate it.

5

Which of the following transfers the torque from the transmission to the drive wheels at a constant speed while accomodating the up and down movement of the suspension?

68% Answer Correctly

control arms

constant velocity (CV) joint

springs

transfer case
Solution

Constant velocity (CV) joints are located at both ends of a half shaft and their purpose is to transfer the torque from the transmission to the drive wheels at a constant speed while accomodating the up and down movement of the suspension. The inner CV joint connects the shaft to the transmission and the outer CV joint connects the shaft to the wheel.
