The distributor is responsible for:
distributing power to the correct drive wheels |
|
recharging the battery |
|
timing the spark and distributing it to the correct cylinder |
|
utlizing battery power to start the engine |
The distributor is driven by the engine's camshaft and is responsible for timing the spark and distributing it to the correct cylinder. The distributor cap contains a rotor that connects the ignition coil (and its high voltage) to the proper cylinder at the proper point in the stroke cycle.
The two major types of vehicle braking systems are:
drum and shoe |
|
disc and shoe |
|
drum and disc |
|
hydraulic and shoe |
Brakes utlize friction to slow vehicle tires. Drum brakes employ a cast iron drum that roates with the vehicle axle. When hydraulic pressure is applied to the brake assemblies at the wheels, internal pistons expand and push brake shoes outward into contact with the brake drum slowing the rotation of the axle. More powerful disc brakes operate by pinching a rotating disc betweeen two brake pads and allow for a larger surface area to contact the disc, provide more force, and are more easily cooled.
The fluid reservoir stores the __________ that the master cylinder uses to maintain hydraulic pressure.
brake oil |
|
air |
|
ethylene glycol |
|
brake fluid |
The fluid reservoir stores the brake fluid that the master cylinder uses to maintain hydraulic pressure.
The spark plugs fire a few extra degrees before top dead center when the engine is running faster. In this case the engine's timing is:
retarded |
|
advanced |
|
synchronous |
|
asynchronous |
Ignition timing defines the point in time at the end of the compression stroke that the spark plug fires. Measured in number of degrees before top dead center (BTDC), the exact point that the spark plugs initiate combustion varies depending on the speed of the engine. The timing is advanced (the spark plugs fire a few more degrees BTDC) when the engine is running faster and retarded when it's running slower.
Ignition timing defines the point in time at the end of the compression stroke that which of the following happens?
intake valve opens |
|
spark plugs fire |
|
the air-fuel mixture enters |
|
exhaust valve opens |
