How are the cylinders numbered in V-type engines?
sequentially from the front of the engine to the back |
|
alternating from the front of the engine to the back |
|
sequentially from the back of the engine to the front |
|
cylinder numbering varies by manufacturer |
In V-type engines the numbering sequence varies by manufacturer.
Which of the following is not a function of a car battery?
delivers supplemental current when the alternator can't handle high electrical system loads |
|
acts as a supplemental source of energy to moderate engine performance |
|
acts as an electrical reservoir for excessive current |
|
delivers current to the ignition system to start the engine |
The lead-acid battery is the core of the electrical system, providing current to the ignition system to start the engine as well as delivering supplemental current when the alternator can't handle high electrical system loads and acting as an electrical reservoir for excessive current.
__________ results from oil buildup in the combustion chamber.
engine knock |
|
preignition |
|
combustion |
|
detonation |
Preignition results from the buildup of fuel deposits and/or oil in the combustion chamber. These deposits increase chamber pressure and reduce heat tranfer to the coolant. The trapped heat then raises the temperature of the air-fuel mix to the point that it combusts before ignition.
A __________ is a drive axle that extends from a transaxle or differential to one of the drive wheels.
steering linkage |
|
drive shaft |
|
control arm |
|
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.
Which of these is not necessary for combustion?
heat source |
|
air |
|
fuel |
|
accelerant |
Combustion is the burning of an air-fuel mixture to provide energy. It requires the presence of air, fuel, and a heat source to ignite the air-fuel mixture. In the internal combustion engine that powers automobiles and trucks the combustion happens inside the engine utilzing a fuel like gasoline, diesel fuel, or natural gas.
