1

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

sequentially from the front of the engine to the back

alternating from the back of the engine to the front

sequentially from the back of the engine to the front
Solution

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

2

Exhaust gases from cylinder exhaust valves are collected by the:

65% Answer Correctly

muffler

catalytic converter

tail pipe

exhaust manifolds
Solution

The cast iron exhaust manifolds collect engine exhaust gas from multiple cylinder exhaust valves and deliver it to the exhaust pipe. Exhaust manifolds can be generic or specially tuned (header pipes) to the engine. Header pipes deliver higher performance but are more expensive and less durable.

3

What is the large casing that contains the cylinders and many of the internal components of the engine?

82% Answer Correctly

transmission

chassis

manifold

engine block
Solution

The engine (or cylinder) block is the large casing that contains the cylinders and many of the internal components of the engine.

4

Which of the following transfers the torque from the transmission to the drive wheels at a constant speed while accomodating the up and down movement of the suspension?

68% Answer Correctly

control arms

constant velocity (CV) joint

transfer case

springs
Solution

Constant velocity (CV) joints are located at both ends of a half shaft and their purpose is to transfer the torque from the transmission to the drive wheels at a constant speed while accomodating the up and down movement of the suspension. The inner CV joint connects the shaft to the transmission and the outer CV joint connects the shaft to the wheel.

5

Coolant is circulated through the engine by the:

61% Answer Correctly

water pump

radiator

camshaft

water jacket
Solution

The water pump is driven by a belt connected to the crankshaft and ensures that coolant moves through the engine and radiator.
