Engines with radial cylinder configurations are most common in:
train engines |
|
aircraft engines |
|
tank engines |
|
heavy truck engines |
A radial arrangement places cylinders in a circle around the crankshaft and is used almost exclusively in aircraft engines.
The wheel __________ is the mounting point for the wheel and tire assembly.
shaft |
|
base |
|
knuckle |
|
hub |
The wheel hub is the mounting point for the wheel and tire assembly. The wheel hub can rotate while being held stable by the steering knuckle which applies the motion of the control arms to the wheels.
What does the timing belt do?
calibrates the speedometer |
|
synchronizes the camshaft and the crankshaft |
|
synchronizes each piston to the crankshaft |
|
synchronizes the cam and the camshaft |
Maintaining proper synchronization between the rotation of the camshaft and the rotation of the crankshaft is critical to ensure that the engine's valves open and close at the proper times during each cylinder's intake and exhaust strokes.
Waste gases from combustion are removed from the combustion chamber by the:
camshaft |
|
head gasket |
|
piston |
|
exhaust 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 primary purpose of the muffler is to:
cool the exhaust |
|
quiet exhaust |
|
remove harmful gases from the exhaust |
|
reclaim unburned fuel |
The muffler follows the catalytic converter and absorbs sound to help quiet load exhaust. It is followed by the exhaust pipe which is the final exit point for exhaust gas from the vehicle.
