Which of the following is not a part of the oil pump?

38% Answer Correctly

oil filter

all of these are part of the oil pump

oil galleries

pressure relief valve


Solution

The oil pump is driven by the camshaft and is responsible for pumping oil through the oil galleries (passages) that run throughout the engine. It also contains the oil filter and a pressure relief valve which prevents excessive pressure from building up in the lubrication system.


2

The right front wheel of your front-wheel drive car drops into a pothole and the left front wheel doesn't lose contact with the road. Which of the following is true?

75% Answer Correctly

your car has an independent rear suspension

your car has an independent front suspension

your car has a rigid axle rear suspension

your car has a rigid axle front suspension


Solution

An independent suspension allows the wheels on either side of an axle to move independently from each other. The fact that the left front wheel didn't move up in response to the right front wheel moving down is evidence of this.


3

Modern car engines are cooled by:

81% Answer Correctly

air conditioner

ice

air

liquid


Solution

Modern car engines are cooled by liquid which circulates through the engine block and cylinder heads absorbing excess heat. This liquid is made up of half water and half antifreeze (commonly, ethylene glycol) which both keeps the water from freezing at low temperatures and raises its boiling point making heat transfer more efficient.


4

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

57% Answer Correctly

arms

cylinder

linkage

column


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

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

57% Answer Correctly

secondary coil winding

tertiary coil winding

distributor coil winding

primary 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.
