The distributor is responsible for:
timing the spark and distributing it to the correct cylinder |
|
utlizing battery power to start the engine |
|
distributing power to the correct drive wheels |
|
recharging the battery |
The distributor is driven by the engine's camshaft and is responsible for timing the spark and distributing it to the correct cylinder. The distributor cap contains a rotor that connects the ignition coil (and its high voltage) to the proper cylinder at the proper point in the stroke cycle.
The __________ provides the appropriate power to vehicle wheels to maintain a given speed.
transmission |
|
gearbox |
|
ignition coil |
|
transaxle |
The transmission provides the appropriate power to vehicle wheels to maintain a given speed. The engine and the transmission have to be disconnected to shift gears and a manual transmission requires the driver to manually manage this disconnection (using a clutch) and to manually shift gears. An automatic transmission is essentially an automatic gear shifter and handles this process without driver input.
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 an independent rear suspension |
|
your car has a rigid axle front suspension |
|
your car has a rigid axle rear suspension |
|
your car has an independent front 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.
The piston moves downward in the cylinder creating a vacuum that pulls an air-fuel mix into the combustion chamber. This describes which engine stroke?
compression |
|
exhaust |
|
power |
|
intake |
The four-stroke piston cycle of internal combustion engines starts with the piston at top of the cylinder head (top dead center or TDC) during the intake stroke. The piston moves downward in the cylinder creating a vacuum that pulls an air-fuel mix into the combustion chamber through the now open intake valve.
Which of the following statements about fuel injection is false?
atomizes fuel using high pressure and injects it into the engine |
|
relies on suction to draw fuel into the engine |
|
has replaced the carburetor as the primary fuel delivery system used in automotive engines |
|
optimizes fuel delivery using various electronic engine sensors |
Fuel injection has replaced the carburetor as the primary automobile fuel delivery system. The main difference between the fuel injector and the carburetor is that fuel injection atomizes the fuel by forcibly pumping it through a small nozzle under high pressure while a carburetor relies on suction to draw fuel into an accelerated intake air stream.
