The catalytic converter output consists primarily of:
oxygen |
|
water and carbon dioxide |
|
carbon monoxide |
|
gasoline |
The catalytic converter converts pollutants in exhaust gas into less pollutant substances like carbon dioxide and water.
For inline cylinder arrangements in an engine, how are the cylinders numbered?
sequentially from the back of the engine to the front |
|
sequentially from the front of the engine to the back |
|
alternating from the front of the engine to the back |
|
alternating from the back of the engine to the front |
Inline cylinder arrangements number cylinders sequentially (1, 2, 3, ...) front to rear.
Which of the following is a common firing order for four-cylinder engines?
1-2-3-4 |
|
4-3-2-1 |
|
1-3-4-2 |
|
3-1-2-4 |
The stroke cycle of an engine is governed by the crankshaft which serves to regulate the firing order of the cylinders. All cylinders are not on the same stroke at the same time and correct firing order is important to balance engine operation and minimize vibrations. A common firing order for four-cylinder engines is 1-3-4-2 which indicates that cylinders 1 and 3 fire (power stroke)together and cylinders 4 and 2 fire together.
A __________ is a drive axle that extends from a transaxle or differential to one of the drive wheels.
drive shaft |
|
control arm |
|
steering linkage |
|
half 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.
Opposed cylinder designs feature two rows of cylinders that are placed at what angle to each other?
180° |
|
270° |
|
90° |
|
45° |
Opposed cylinder designs place cylinders flat in two rows 180° opposite each other with a single crankshaft running between them.
