1

Which engine component converts the reciprocating motion of the piston into the rotational motion that's used to power the vehicle and its components?

73% Answer Correctly

driveshaft

camshaft

crankshaft

halfshaft


Solution

The crankshaft converts the reciprocating motion of the piston into the rotational motion that's used to power the vehicle and its components.


2

Cylinder air and fuel intake valves, exhaust valves, and mounts for spark plugs and fuel injectors are contained in the:

45% Answer Correctly

cylinder head

head gasket

manifold

piston ring


Solution

Cylinders act as a guide for the pistons that translate the heat energy of combustion into the mechanical energy necessary to move a vehicle. Piston rings seal the piston to the cylinder to contain combustion gases and also regulate the oil distribution between the piston and cylinder wall. A cylinder head closes in the top of the cylinder forming the combustion chamber which is sealed by a head gasket (head). The head provides space for air and fuel intake valves, exhaust valves, and mounts for spark plugs and fuel injectors.


3

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

57% Answer Correctly

distributor coil winding

tertiary coil winding

primary coil winding

secondary 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.


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

transfer case

control arms

constant velocity (CV) joint

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.

82% Answer Correctly

valve
