1

__________ are made with wide gap coils of rigid steel cable and both hold the vehicle chassis up off the ground and absorb energy from wheel movement making for a smoother ride.

67% Answer Correctly

ignition coils

control arms

shock absorbers

suspension springs
Solution

Suspension springs are made with wide gap coils of rigid steel cable and both hold the vehicle chassis up off the ground and absorb energy from wheel movement making for a smoother ride.

2

Too much fuel results in a __________ air-fuel mixture that burns quicker and cooler.

63% Answer Correctly

rich

heavy

light

lean
Solution

The stoichiometric ratio defines the proper ratio of air to fuel necessary so that an engine burns all fuel with no excess air. For gasoline fuel, the stoichiometric ratio is about 14.7:1 or for every one gram of fuel, 14.7 grams of air are required. Too much air results in a lean air-fuel mixture that burns more slowly and hotter while too much fuel results in a rich mixture that burns quicker and cooler.

3

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

70% Answer Correctly

pickup tube

pressure relief valve

oil filter

differential
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.

4

Opposed cylinder designs feature two rows of cylinders that are placed at what angle to each other?

49% Answer Correctly

90°

45°

180°

270°
Solution

Opposed cylinder designs place cylinders flat in two rows 180° opposite each other with a single crankshaft running between them.

50% Answer Correctly

sequentially from the front of the engine to the back

sequentially from the back of the engine to the front

alternating from the back of the engine to the front

alternating from the front of the engine to the back
