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 front suspension |
|
your car has an independent rear suspension |
|
your car has an independent front suspension |
|
your car has a rigid axle 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.
The air-fuel mixture is delivered to the combustion chamber by a(n):
intake valve |
|
exhaust valve |
|
air valve |
|
fuel valve |
The combustion chamber is located in the cylinder head and contains the combustion of the air-fuel mixture. This mixture is delivered by an intake valve and the waste gases from combustion are removed from the combustion chamber by the exhaust valve.
The __________ converts pressure on the brake pedal to hydraulic pressure in the brake lines.
brake cylinder |
|
master cylinder |
|
brake knuckle |
|
brake linkage |
The master (brake) cylinder converts pressure on the brake pedal to hydraulic pressure in the brake lines.
Engines with radial cylinder configurations are most common in:
tank engines |
|
aircraft engines |
|
heavy truck engines |
|
train engines |
A radial arrangement places cylinders in a circle around the crankshaft and is used almost exclusively in aircraft engines.
A cylinders acts as a guide for a:
valve |
|
camshaft |
|
driveshaft |
|
piston |
Cylinders act as a guide for the pistons that translate the heat energy of combustion into the mechanical energy necessary to move a vehicle. Piston rings seal the piston to the cylinder to contain combustion gases and also regulate the oil distribution between the piston and cylinder wall. A cylinder head closes in the top of the cylinder forming the combustion chamber which is sealed by a head gasket (head). The head provides space for air and fuel intake valves, exhaust valves, and mounts for spark plugs and fuel injectors.
