How are the cylinders numbered in V-type engines?
alternating from the front of the engine to the back |
|
sequentially from the front of the engine to the back |
|
cylinder numbering varies by manufacturer |

sequentially from the back of the engine to the front |
In V-type engines the numbering sequence varies by manufacturer.
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 __________ ℃.

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 ℃.
__________ 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.
suspension springs |
|
control arms |
|
shock absorbers |
|
ignition coils |
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.
Which of the following is not a function of the oil pan?
screens debris from oil |
|
acts as the engine oil reservoir |
|
cools engine oil |
|
feeds the oil pump |
The oil pan contains the engine oil reservoir of from four to six quarts of oil and feeds the oil pump through the oil pickup tube. An oil strainer floats at the top of the oil in the oil pan and screens debris from the oil before feeding it to the oil pump.
Which of the following is a common firing order for four-cylinder engines?
1-3-4-2 |
|
1-2-3-4 |
|
4-3-2-1 |
|
3-1-2-4 |
The stroke cycle of an engine is governed by the crankshaft which serves to regulate the firing order of the cylinders. All cylinders are not on the same stroke at the same time and correct firing order is important to balance engine operation and minimize vibrations. A common firing order for four-cylinder engines is 1-3-4-2 which indicates that cylinders 1 and 3 fire (power stroke)together and cylinders 4 and 2 fire together.
