What function does a two-stroke cycle engine perform on the second stroke?
fuel intake and compression |
|
combustion and exhaust |
|
compression and combustion |
|
fuel intake and exhaust |
The two strokes of a two-stroke cycle engine are fuel intake and compression then combustion and exhaust.
What's the name of the high-voltage winding in the ignition coil?
initial coil winding |
|
battery 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.
Cylinder air and fuel intake valves, exhaust valves, and mounts for spark plugs and fuel injectors are contained in the:
piston ring |
|
manifold |
|
cylinder head |
|
head gasket |
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.
When a car engine is running, what provides electrical current to recharge the battery and power the electrical system?
solenoid |
|
battery |
|
camshaft |
|
alternator |
Once the engine is running, the alternator provides electrical current to recharge the battery and power the electrical system. The alternator is driven by the engine's crankshaft and produces alternating current (AC) which is then fed through a rectifier bridge to convert it to the direct current (DC) required by the electrical system. A voltage regulator controls the output of the alternator to maintain a consistent voltage (approx. 14.5 volts) in the electrical system regardless of load.
The combustion chamber is enclosed by the:
piston ring |
|
piston |
|
cylinder head |
|
head gasket |
