1

The steering __________ transfers the motion of the steering gear output shaft to the steering arms that turn the wheels.

57% Answer Correctly

arms

column

linkage

cylinder


Solution

The steering linkage is a system of pivots and connecting parts between the steering gear and the control arms. The steering linkage transfers the motion of the steering gear output shaft to the steering arms that turn the wheels.


2

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

65% Answer Correctly

engine is shorter than an inline engine

has two rows of cylinders

has an odd number of cylinders

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.


3

The fuel injector is regulated by the __________ which is the main computer that controls engine and transmission functions.

60% Answer Correctly

transmission control module

computer control module

powertrain control module

vehicle control module


Solution

The fuel injector sprays fuel into the air stream that's being fed into the cylinder head via the intake valve. The timing and amount of fuel are regulated by the powertrain control module (PCM) which is the main computer that controls engine and transmission functions.


4

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

63% Answer Correctly

lean

light

heavy

rich


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.


5

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

86% Answer Correctly

piston

exhaust valve

camshaft

head gasket


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.
