1

For inline cylinder arrangements in an engine, how are the cylinders numbered?

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 front of the engine to the back

alternating from the back of the engine to the front


Solution

Inline cylinder arrangements number cylinders sequentially (1, 2, 3, ...) front to rear.


2

__________ 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

suspension springs

control arms

shock absorbers

ignition coils


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.


3

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

86% Answer Correctly

piston

camshaft

head gasket

exhaust valve


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.


4

Engine oil viscosity is rated using the format XW-XX with the number preceding the W indicating viscosity at __________ ℉ and the XX indicating viscosity at __________ ℃.

66% Answer Correctly

0, 100

100, 0

0, 0

100, 100


Solution

The primary component of the lubrication system is engine oil. Engines require oil blends with different thickness (viscosity) and additives depending on their operating conditions. Viscosity is rated using the format XW-XX with the number preceding the W (winter) rating the oil’s viscosity at 0 ℉ (-17.8 ℃) and the XX indicating viscosity at 100 ℃.


5

What's the name of the high-voltage winding in the ignition coil?

51% Answer Correctly

primary coil winding

initial coil winding

secondary coil winding

battery coil winding


Solution

The ignition coil is a high-voltage transformer made up of two coils of wire. The primary coil winding is the low-voltage winding and has relatively few turns of heavy wire. The secondary coil winding is the high-voltage winding that surrounds the primary and is made up of thousands of turns of fine wire. Current flows from the battery through the primary coil winding which creates a changing magnetic field inside the secondary coil. This induces a very high-voltage current in the secondary coil which it feeds to the distributor.
