1

The distributor is responsible for:

71% Answer Correctly

timing the spark and distributing it to the correct cylinder

distributing power to the correct drive wheels

recharging the battery

utlizing battery power to start the engine


Solution

The distributor is driven by the engine's camshaft and is responsible for timing the spark and distributing it to the correct cylinder. The distributor cap contains a rotor that connects the ignition coil (and its high voltage) to the proper cylinder at the proper point in the stroke cycle.


2

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

70% Answer Correctly

differential

pickup tube

oil filter

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.


3

What is the function of the alternator?

59% Answer Correctly

converts motion from the wheels into DC power

replaces the electrical energy that the car draws from the battery

provides AC power for the car's electrical components

charges the battery when the car is not running


Solution

An automobile's electrical system runs on DC power and the bulk of that power is supplied by the battery. The alternator converts the motion of the rotor into AC power which is then fed through the rectifier to convert it to DC power that both the car and the battery can use.


4

What function does a two-stroke cycle engine perform on the second stroke?

52% Answer Correctly

fuel intake and exhaust

combustion and exhaust

fuel intake and compression

compression and combustion


Solution

The two strokes of a two-stroke cycle engine are fuel intake and compression then combustion and exhaust.


5

Engines with radial cylinder configurations are most common in:

60% Answer Correctly

train engines

heavy truck engines

aircraft engines

tank engines


Solution

A radial arrangement places cylinders in a circle around the crankshaft and is used almost exclusively in aircraft engines.
