What's the name of the low-voltage winding in the ignition coil?
primary coil winding |
|
secondary coil winding |
|
tertiary coil winding |
|
distributor coil winding |
The ignition coil is a high-voltage transformer made up of two coils of wire. The primary coil winding is the low-voltage winding and has relatively few turns of heavy wire. The secondary coil winding is the high-voltage winding that surrounds the primary and is made up of thousands of turns of fine wire. Current flows from the battery through the primary coil winding which creates a changing magnetic field inside the secondary coil. This induces a very high-voltage current in the secondary coil which it feeds to the distributor.
What provides the power necessary to start a car?
spark plugs |
|
powertrain control module |
|
battery |
|
alternator |
The battery supplies the power necessary to start the engine when the ignition switch is is turned on.
What is the large casing that contains the cylinders and many of the internal components of the engine?
engine block |
|
chassis |
|
manifold |
|
transmission |
The engine (or cylinder) block is the large casing that contains the cylinders and many of the internal components of the engine.
__________ results from oil buildup in the combustion chamber.
detonation |
|
combustion |
|
engine knock |
|
preignition |
Preignition results from the buildup of fuel deposits and/or oil in the combustion chamber. These deposits increase chamber pressure and reduce heat tranfer to the coolant. The trapped heat then raises the temperature of the air-fuel mix to the point that it combusts before ignition.
A constant velocity (CV) joint is closely related to which of the following?
master cylinder |
|
sprint joint |
|
universal joint |
|
ball joint |
Like CV joints, universal joints (U-joints) are located at each end of a drive shaft and allow the shaft to operate at a variable angle with the item it is driving. Universal joints perform the same basic function as CV joints but CV joints have a wider range of operation.
