What links each piston to the engine's crankshaft?
cylinder arm |
|
piston ring |
|
halfshaft |
|
connecting rod |
A connecting rod employs a wrist pin to link each piston to the engine's crankshaft.
Which of the following is a relay that connects the battery to the starter motor when the ignition key is turned?
ignition coil |
|
alternator |
|
solenoid |
|
actuator |
The cylindrical solenoid is a relay that safely connects the high amperage battery to the starter motor when the ignition key is turned. This current then allows the engine to turn at a high enough speed to start.
Which of the following regulates the opening and closing of the intake and exhaust valves in each cylinder in time with the motion of the piston?
connecting arm |
|
crankshaft |
|
halfshaft |
|
camshaft |
The camshaft is linked to the crankshaft through a timing belt and regulates the opening and closing of the intake and exhaust valves in each cylinder in time with the motion of the piston. An engine designated OverHead Camshaft (OHC) locates the camshaft in the cylinder head. An engine with Double OverHead Camshaft (DOHC) has two camshafts, one to regulate the intake valves and one to regulate the exhaust valves.
What provides the power necessary to start a car?
battery |
|
spark plugs |
|
alternator |
|
powertrain control module |
The battery supplies the power necessary to start the engine when the ignition switch is is turned on.
The vehicle's computer system gets data from:
inhibitors |
|
regulators |
|
sensors |
|
actuators |
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.
