power, intake, compression, exhaust |
|
compression, intake, power, exhaust |

__________ results from oil buildup in the combustion chamber.
preignition |
|
detonation |
|
engine knock |
|
combustion |
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.
What is the function of the alternator?
converts motion from the wheels into DC power |
|
provides AC power for the car's electrical components |
|
charges the battery when the car is not running |
|
replaces the electrical energy that the car draws from the battery |
An automobile's electrical system runs on DC power and the bulk of that power is supplied by the battery. The alternator converts the motion of the rotor into AC power which is then fed through the rectifier to convert it to DC power that both the car and the battery can use.
The __________ splits engine power between the front and rear axles of four-wheel drive vehicles.
universal joint |
|
master cylinder |
|
transfer case |
|
transmission linkage |
The transfer case splits engine power between the front and rear axles of four-wheel drive vehicles.
The vehicle's computer system gets data from:
regulators |
|
actuators |
|
inhibitors |
|
sensors |
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.
