BASVAB 2023-2024 AUTO INFORMATION
COMPLETE DETAILED CASE STUDY
the high-voltage winding in a car's ignition system is called the _______ - secondary coil winding
Why is a coolant recovery reservoir necessary? - to capture overflow when the radiator pressure cap
valve opens, because the flow of coolant between the engine and radiator varies based on the heat of
the engine.
The _______ is the main component of charging system and converts mechanical energy into electrical
energy. - alternator
The AC electricity produced by the alternator is converted to DC by the ______. - rectifier (or rectifier
bridge)
Define piston - a cylindrical object that moves up and down inside an engine's cylinder.
what happens in an engine's oil pan? - oil drips from various engine parts into the pan, cools, and is
picked up by the oil tube and sent back to the oil pump.
______ send data to a car's computer; ______ receive commands from a car's computer. - Sensors;
actuators
what are the two major types of engine cooling systems? - air-cooling and water-cooling
what does a crankshaft do? - converts the linear motion of the piston into rotary motion.
_______ protect other car parts from the energy produced by the up-and-down movement of the
wheels. - shock absorbers
, what are oil galleries? - passages throughout the engine that deliver oil to various engine components.
in most cars, exhaust gases pass from the catalytic converter and through the ________ before leaving
the car. - muffler
what does a connecting rod do? - connect each piston to the engine's crankshaft.
OHV stands for _________. - overhead valve
does a car's battery provide AC or DC electricity? - DC
what are the ball joints? - ball-and-socket arrangements that allow the steering knuckle to turn and
move up and down.
what do piston rings do? - seal the cylinder so that exhaust gases do not leak out and oil does not leak in.
what flows through radiator hoses? - coolant flowing from the radiator to the engine and returning from
the engine to the radiator.
________ can transmit power through very steep angles in order to transfer mechanical energy to the
car's wheels. - Constant velocity (CV) joints
define engine block. - A framework in which the cylinders are arranged.
a radiator cap has two valves: a(n) _________ valve and a(n) ________ valve. - pressure; vacuum
define viscosity. - resistance to flow
internal combustion engines take ______ energy, convert it into _____ energy and then into _____
energy. - chemical; heat; mechanical
