Which of the following is not a part of the oil pump?
oil filter |
|
all of these are part of the oil pump |
|
oil galleries |
|
pressure relief valve |
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.
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?
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 |
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.
Modern car engines are cooled by:
air conditioner |
|
ice |
|
air |
|
liquid |
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.
The steering __________ transfers the motion of the steering gear output shaft to the steering arms that turn the wheels.
arms |
|
cylinder |
|
linkage |
|
column |
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.
What's the name of the low-voltage winding in the ignition coil?
secondary coil winding |
|
tertiary coil winding |
|
distributor coil winding |
|
primary coil winding |
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.
