1

What does the timing belt do?

64% Answer Correctly

synchronizes the camshaft and the crankshaft

calibrates the speedometer

synchronizes each piston to the crankshaft

synchronizes the cam and the camshaft


Solution

Maintaining proper synchronization between the rotation of the camshaft and the rotation of the crankshaft is critical to ensure that the engine's valves open and close at the proper times during each cylinder's intake and exhaust strokes.


2

What is the function of the alternator?

59% Answer Correctly

charges the battery when the car is not running

provides AC power for the car's electrical components

converts motion from the wheels into DC power

replaces the electrical energy that the car draws from the battery


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.


3

Which of the following statements about v-type cyllinder arrangement is false?

65% Answer Correctly

has an odd number of cylinders

has two rows of cylinders

engine is shorter than an inline engine

common in motorcycles, cars, and trucks


Solution

A v-arrangement has two rows of cylinders in a V-shaped block with a crankshaft at the bottom of the V. Any even number of cylinders is possible in this configuration from the V-2 that's commonly used in motorcycles up to V-12 or bigger for large trucks. The V design produces a shorter engine than an in-line cylinder configuration and allows for better air-fuel distribution.


4

Waste gases from combustion are removed from the combustion chamber by the:

86% Answer Correctly

head gasket

camshaft

exhaust valve

piston


Solution

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.


5

A __________ is a drive axle that extends from a transaxle or differential to one of the drive wheels.

51% Answer Correctly

control arm

half shaft

steering linkage

drive shaft


Solution

A half shaft is a drive axle that extends from a transaxle or differential to one of the drive wheels. There are two half shafts per drive axle, one for each wheel, each doing "half" the job.
