A constant velocity (CV) joint is closely related to which of the following?
universal joint |
|
master cylinder |
|
sprint joint |
|
ball joint |
Like CV joints, universal joints (U-joints) are located at each end of a drive shaft and allow the shaft to operate at a variable angle with the item it is driving. Universal joints perform the same basic function as CV joints but CV joints have a wider range of operation.
The __________ splits engine power between the front and rear axles of four-wheel drive vehicles.
universal joint |
|
transfer case |
|
transmission linkage |
|
master cylinder |
The transfer case splits engine power between the front and rear axles of four-wheel drive vehicles.
Too much air results in a __________ air-fuel mixture that burns more slowly and hotter.
light |
|
heavy |
|
lean |
|
rich |
The stoichiometric ratio defines the proper ratio of air to fuel necessary so that an engine burns all fuel with no excess air. For gasoline fuel, the stoichiometric ratio is about 14.7:1 or for every one gram of fuel, 14.7 grams of air are required. Too much air results in a lean air-fuel mixture that burns more slowly and hotter while too much fuel results in a rich mixture that burns quicker and cooler.
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 front suspension |
|
your car has an independent rear suspension |
|
your car has a rigid axle front suspension |
|
your car has a rigid axle rear 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.
What does the timing belt do?
synchronizes the camshaft and the crankshaft |
|
synchronizes the cam and the camshaft |
|
synchronizes each piston to the crankshaft |
|
calibrates the speedometer |
Maintaining proper synchronization between the rotation of the camshaft and the rotation of the crankshaft is critical to ensure that the engine's valves open and close at the proper times during each cylinder's intake and exhaust strokes.
