The __________ converts pressure on the brake pedal to hydraulic pressure in the brake lines.
brake cylinder |
|
brake knuckle |
|
master cylinder |
|
brake linkage |
The master (brake) cylinder converts pressure on the brake pedal to hydraulic pressure in the brake lines.
The firing order of the cylinders in an engine can be found by:
observing the direction in which the intake valves open |
|
reversing the cylinder number |
|
identifying the cylinder number |
|
observing the order in which the intake valves open |
The firing order of the cylinders in an engine is different than the cynlinder numbers and can be found by observing the order in which the intake valves open.
What function does a two-stroke cycle engine perform on the second stroke?
fuel intake and exhaust |
|
combustion and exhaust |
|
compression and combustion |
|
fuel intake and compression |
The two strokes of a two-stroke cycle engine are fuel intake and compression then combustion and exhaust.
Power brakes multiply the force a driver applies to the brake pedal using a __________ connected to the engine intake manifold.
cylinder |
|
brake line |
|
speed sensor |
|
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.
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.
