How are the cylinders numbered in V-type engines?
alternating from the front of the engine to the back |
|
sequentially from the back of the engine to the front |
|
sequentially from the front of the engine to the back |
|
cylinder numbering varies by manufacturer |
In V-type engines the numbering sequence varies by manufacturer.
What is the function of the head gasket?
to seal the engine block from the cylinders |
|
to seal the exhaust system from the drive train |
|
to seal the brake assembly from external contaminants |
|
to connect the transmission to the drive train |
A head gasket is a gasket that sits between the engine block and cylinder heads to seal the cylinders to ensure maximum compression and avoid leakage of coolant or engine oil into the cylinders.
Which of the following transfers the torque from the transmission to the drive wheels at a constant speed while accomodating the up and down movement of the suspension?
constant velocity (CV) joint |
|
springs |
|
control arms |
|
transfer case |
Constant velocity (CV) joints are located at both ends of a half shaft and their purpose is to transfer the torque from the transmission to the drive wheels at a constant speed while accomodating the up and down movement of the suspension. The inner CV joint connects the shaft to the transmission and the outer CV joint connects the shaft to the wheel.
A vehicle's lighting system is protected from current spikes by:
the battery |
|
the alternator |
|
the voltage regulator |
|
fuses and circuit breakers |
The lighting system consists of interior lights, instrument panel lighting, headlights, and taillights. Like household electrical circuits, the vehicle's lighting system is protected from current spikes by fuses and circuit breakers.
The fuel injectors are fed fuel by the:
powertrain control module |
|
fuel return line |
|
electric fuel pump |
|
fuel pressure regulator |
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.
