1

Which of the following enables heat transfer from the cylinder heads to the coolant?

49% Answer Correctly

radiator

water sleeve

water jacket

water pump


Solution

A water jacket is a coolant-filled casing that allows heat transfer from the engine block and cylinder heads to the liquid coolant.


2

Another name for the powertrain control module is the __________ control unit.

54% Answer Correctly

universal

electrical

transmission

engine


Solution

The main computer or powertrain control module (PCM) uses pre-programmed software to analyze the input received from sensors and produce output signals to adjust vehicle performance and operation. (Engine control unit (ECU) is another name for the PCM.)


3

How are the cylinders numbered in V-type engines?

42% Answer Correctly

cylinder numbering varies by manufacturer

alternating from the front of the engine to the back

sequentially from the front of the engine to the back

sequentially from the back of the engine to the front


Solution

In V-type engines the numbering sequence varies by manufacturer.


4

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

57% Answer Correctly

cylinder

column

linkage

arms


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.


5

Which of the following cylinder arrangement would be most common in an eight cylinder engine?

79% Answer Correctly

V-type

vertical

opposed

inline


Solution

Cylinder number and arrangement depends on the purpose of the engine. Smaller (four and six cylinder) engines in front-wheel drive vehicles often use an inline design which orients cylinders vertically over the crankshaft and aligns them in a row. Other common orientations are a horizontal/opposed design which places cylinders flat facing each other with the crankshaft between them and a V-type design common in six and eight cylinder engines that features one cylinder head per block of cylinders oriented at a 60 to 90 degree angle to each other with the crankshaft at the bottom of the V.
