1

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

57% Answer Correctly

linkage

column

cylinder

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.


2

What function does a two-stroke cycle engine perform on the second stroke?

51% Answer Correctly

combustion and exhaust

compression and combustion

fuel intake and compression

fuel intake and exhaust


Solution

The two strokes of a two-stroke cycle engine are fuel intake and compression then combustion and exhaust.


3

The fluid reservoir stores the __________ that the master cylinder uses to maintain hydraulic pressure.

79% Answer Correctly

ethylene glycol

air

brake oil

brake fluid


Solution

The fluid reservoir stores the brake fluid that the master cylinder uses to maintain hydraulic pressure.


4

Which of the following regulates the opening and closing of the intake and exhaust valves in each cylinder in time with the motion of the piston?

65% Answer Correctly

camshaft

crankshaft

connecting arm

halfshaft


Solution

The camshaft is linked to the crankshaft through a timing belt and regulates the opening and closing of the intake and exhaust valves in each cylinder in time with the motion of the piston. An engine designated OverHead Camshaft (OHC) locates the camshaft in the cylinder head. An engine with Double OverHead Camshaft (DOHC) has two camshafts, one to regulate the intake valves and one to regulate the exhaust valves.


5

The piston moves downward in the cylinder creating a vacuum that pulls an air-fuel mix into the combustion chamber. This describes which engine stroke?

68% Answer Correctly

compression

power

intake

exhaust


Solution

The four-stroke piston cycle of internal combustion engines starts with the piston at top of the cylinder head (top dead center or TDC) during the intake stroke. The piston moves downward in the cylinder creating a vacuum that pulls an air-fuel mix into the combustion chamber through the now open intake valve.
