Which of the following is not a function of the oil pan?
acts as the engine oil reservoir |
|
screens debris from oil |
|
feeds the oil pump |
|
cools engine oil |
The oil pan contains the engine oil reservoir of from four to six quarts of oil and feeds the oil pump through the oil pickup tube. An oil strainer floats at the top of the oil in the oil pan and screens debris from the oil before feeding it to the oil pump.
What type of energy does an automotive battery produce?
rotational energy |
|
alternating current |
|
chemical energy |
|
direct current |
An automotive battery produces direct current for use by automotive systems.
Power brakes multiply the force a driver applies to the brake pedal using a __________ connected to the engine intake manifold.
speed sensor |
|
cylinder |
|
brake line |
|
vacuum booster |
Power brakes multiply the force a driver applies to the brake pedal using a vacuum booster connected to the engine intake manifold. This provides for much higher hydraulic pressure in the braking system than could be generated by the driver alone. Antilock brakes (ABS) use speed sensors and adjust the brake pressure at each wheel to prevent skidding and allow the driver more steering control in slippery conditions.
Both intake and exhaust valves are closed as the piston begins moving back up from the bottom of the cylinder, compressing the air-fuel mixture in the combustion chamber which also makes it hotter. This describes which engine stroke?
intake |
|
power |
|
exhaust |
|
compression |
During the compression stroke, both intake and exhaust valves are closed as the piston begins moving back up from the bottom of the cylinder (bottom dead center or BDC). This compresses the air-fuel mixture in the combustion chamber which also makes it hotter.
What is the pimary advantage of using power brakes on a vehicle?
utilizes battery power to assist in braking |
|
allows the use of antilock brakes |
|
requires less brake fluid to operate the braking system |
|
provides higher hydraulic pressure in the braking system |
