Spark plugs receive current from the:
alternator |
|
ignition coil |
|
battery |
|
distributor |
Spark plugs receive current from the distributor and use it to spark combustion in the combustion chamber of a cylinder.
The fuel pressure regulator ensures that the fuel injectors receive fuel at a consistent and known rate. The fuel pressure regulator is part of the:
fuel filter |
|
fuel rail |
|
fuel manifold |
|
electric fuel pump |
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.
Which of the following regulates the flow of coolant through the radiator?
crankshaft |
|
thermostat |
|
water pump |
|
water jacket |
The thermostat controls coolant (and, through it, engine) temperature by regulating the flow of coolant through the radiator. A bypass tube allows coolant to bypass the radiator and flow back into the water pump when its temperature is low enough that the thermostat is closed.
