Opposed cylinder designs feature two rows of cylinders that are placed at what angle to each other?
90° |
|
45° |
|
180° |
|
270° |
Opposed cylinder designs place cylinders flat in two rows 180° opposite each other with a single crankshaft running between them.
Which of the following is the result of the air-fuel mixture exploding instead of burning?
post-ignition |
|
pre-detonation |
|
pre-ignition |
|
detonation |
Normal combustion in an engine is initiated by a spark plug and results in the complete burning of the air-fuel mixture. If combustion is initiated by a source other than the spark plug, by a hot spot in the cylinder or combustion chamber for example, pre-ignition results. Detonation results if the air-fuel mixture explodes instead of burning. Detonation can cause extremes in pressure in the combustion chamber leading to engine damage.
Spark plugs receive current from the:
ignition coil |
|
distributor |
|
alternator |
|
battery |
Spark plugs receive current from the distributor and use it to spark combustion in the combustion chamber of a cylinder.
The catalytic converter output consists primarily of:
carbon monoxide |
|
oxygen |
|
gasoline |
|
water and carbon dioxide |
The catalytic converter converts pollutants in exhaust gas into less pollutant substances like carbon dioxide and water.
Which engine component converts the reciprocating motion of the piston into the rotational motion that's used to power the vehicle and its components?
halfshaft |
|
crankshaft |
|
driveshaft |
|
camshaft |
The crankshaft converts the reciprocating motion of the piston into the rotational motion that's used to power the vehicle and its components.
