Waste gases from combustion are removed from the combustion chamber by the:
exhaust valve |
|
camshaft |
|
piston |
|
head gasket |
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.
What's the name of the low-voltage winding in the ignition coil?
tertiary coil winding |
|
distributor coil winding |
|
primary coil winding |
|
secondary 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.
The intake ports on the cylinder heads is fed outside air via the:
intake air pump |
|
intake manifold |
|
intake control module |
|
intake pressure regulator |
The intake manifold distributes outside air to the intake ports on the cylinder heads. The intake air filter removes any airborne contaminants before the air enters the engine.
Which of the following is not an advantage that disc brakes have over drum brakes?
are more easily cooled |
|
provide a larger contact area |
|
use less brake fluid |
|
provide more braking force |
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.
What is the function of the head gasket?
to connect the transmission to the drive train |
|
to seal the exhaust system from the drive train |
|
to seal the brake assembly from external contaminants |
|
to seal the engine block from the cylinders |
A head gasket is a gasket that sits between the engine block and cylinder heads to seal the cylinders to ensure maximum compression and avoid leakage of coolant or engine oil into the cylinders.
