Gases from combustion are pushed out through the exhaust valve as the piston travels up the cylinder to top dead center. This describes which engine stroke?
intake |
|
power |
|
compression |
|
exhaust |
During the exhaust stroke, just before the piston reaches bottom dead center the exhaust valve opens. The resulting gases from combustion are then pushed out through the exhaust valve as the piston travels up the cylinder to top dead center, completing stroke four of the four-stroke piston cycle.
What is the large casing that contains the cylinders and many of the internal components of the engine?
chassis |
|
manifold |
|
transmission |
|
engine block |
The engine (or cylinder) block is the large casing that contains the cylinders and many of the internal components of the engine.
What function does a two-stroke cycle engine perform on the second stroke?
fuel intake and exhaust |
|
fuel intake and compression |
|
compression and combustion |
|
combustion and exhaust |
The two strokes of a two-stroke cycle engine are fuel intake and compression then combustion and exhaust.
Which of the following is not a function of a car battery?
acts as a supplemental source of energy to moderate engine performance |
|
acts as an electrical reservoir for excessive current |
|
delivers supplemental current when the alternator can't handle high electrical system loads |
|
delivers current to the ignition system to start the engine |
The lead-acid battery is the core of the electrical system, providing current to the ignition system to start the engine as well as delivering supplemental current when the alternator can't handle high electrical system loads and acting as an electrical reservoir for excessive current.
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 a rigid axle rear suspension |
|
your car has an independent front suspension |
|
your car has a rigid axle front suspension |
|
your car has an independent rear 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.
