For inline cylinder arrangements in an engine, how are the cylinders numbered?
sequentially from the back of the engine to the front |
|
alternating from the front of the engine to the back |
|
alternating from the back of the engine to the front |

sequentially from the front of the engine to the back |
Inline cylinder arrangements number cylinders sequentially (1, 2, 3, ...) front to rear.
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 a rigid axle front suspension |
|
your car has an independent front suspension |
|
your car has a rigid axle rear suspension |
|
your car has an independent 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.
Engine oil viscosity is rated using the format XW-XX with the number preceding the W indicating viscosity at __________ ℉ and the XX indicating viscosity at __________ ℃.

The primary component of the lubrication system is engine oil. Engines require oil blends with different thickness (viscosity) and additives depending on their operating conditions. Viscosity is rated using the format XW-XX with the number preceding the W (winter) rating the oil’s viscosity at 0 ℉ (-17.8 ℃) and the XX indicating viscosity at 100 ℃.
A __________ is a drive axle that extends from a transaxle or differential to one of the drive wheels.
control arm |
|
half shaft |
|
steering linkage |
|
drive shaft |
A half shaft is a drive axle that extends from a transaxle or differential to one of the drive wheels. There are two half shafts per drive axle, one for each wheel, each doing "half" the job.
The vehicle's computer system gets data from:
sensors |
|
inhibitors |
|
regulators |
|
actuators |
Sensors provide the data necessary for the vehicle's computer to make decisions and monitor everything from simple vehicle information like tire pressure to complexities like the chemical content of an engine's exhaust.
