1

The air-fuel mixture is delivered to the combustion chamber by a(n):

76% Answer Correctly

exhaust valve

intake valve

air valve

fuel 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.

2

What combines the suspension spring and shock absorber into one unit?

73% Answer Correctly

wheel hub

wheel cylinder

knuckle

strut
Solution

Because a compressed spring will ex­tend violently, shock absorbers must be used to dampen the spring’s compression and extension cycles. Struts combine the spring and shock into one unit

3

A constant velocity (CV) joint is closely related to which of the following?

63% Answer Correctly

ball joint

sprint joint

master cylinder

universal joint
Solution

Like CV joints, universal joints (U-joints) are located at each end of a drive shaft and allow the shaft to operate at a variable angle with the item it is driving. Universal joints perform the same basic function as CV joints but CV joints have a wider range of operation.

4

Both intake and exhaust valves are closed as the piston begins moving back up from the bottom of the cylinder, compressing the air-fuel mixture in the combustion chamber which also makes it hotter. This describes which engine stroke?

73% Answer Correctly

intake

compression

exhaust

power
Solution

During the compression stroke, both intake and exhaust valves are closed as the piston begins moving back up from the bottom of the cylinder (bottom dead center or BDC). This compresses the air-fuel mixture in the combustion chamber which also makes it hotter.

5

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

50% Answer Correctly

alternating from the front of the engine to the back

alternating from the back of the engine to the front

sequentially from the front of the engine to the back

sequentially from the back of the engine to the front
Solution

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