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

springs

transfer case

control arms

constant velocity (CV) joint
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.

4

__________ results from oil buildup in the combustion chamber.

43% Answer Correctly

detonation

engine knock

combustion

preignition
Solution

Preignition results from the buildup of fuel deposits and/or oil in the combustion chamber. These deposits increase chamber pressure and reduce heat tranfer to the coolant. The trapped heat then raises the temperature of the air-fuel mix to the point that it combusts before ignition.

5

A vehicle's lighting system is protected from current spikes by:

69% Answer Correctly

the voltage regulator

fuses and circuit breakers

the battery

the alternator
Solution

The lighting system consists of interior lights, instrument panel lighting, headlights, and taillights. Like household electrical circuits, the vehicle's lighting system is protected from current spikes by fuses and circuit breakers.
