1

The fuel injectors are fed fuel by the:

65% Answer Correctly

fuel pressure regulator

powertrain control module

fuel return line

electric fuel pump


Solution

The electric fuel pump feeds pressurized fuel through a fuel filter to the fuel injectors via the fuel rail manifold. The fuel rail contains the fuel pressure regulator which ensures that the fuel injectors receive fuel at a consistent and known rate. Excess fuel bled off by the pressure regulator returns to the fuel tank through the fuel return line.


2

The intake ports on the cylinder heads is fed outside air via the:

67% Answer Correctly

intake manifold

intake pressure regulator

intake air pump

intake control module


Solution

The intake manifold distributes outside air to the intake ports on the cylinder heads. The intake air filter removes any airborne contaminants before the air enters the engine.


3

What's the name of the high-voltage winding in the ignition coil?

51% Answer Correctly

battery coil winding

primary coil winding

secondary coil winding

initial coil winding


Solution

The ignition coil is a high-voltage transformer made up of two coils of wire. The primary coil winding is the low-voltage winding and has relatively few turns of heavy wire. The secondary coil winding is the high-voltage winding that surrounds the primary and is made up of thousands of turns of fine wire. Current flows from the battery through the primary coil winding which creates a changing magnetic field inside the secondary coil. This induces a very high-voltage current in the secondary coil which it feeds to the distributor.


4

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?

75% Answer Correctly

your car has an independent front suspension

your car has an independent rear suspension

your car has a rigid axle front suspension

your car has a rigid axle rear suspension


Solution

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.


5

The __________ provides the appropriate power to vehicle wheels to maintain a given speed.

75% Answer Correctly

ignition coil

transmission

gearbox

transaxle


Solution

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.
