Ch.1&2 The Automobile, Automotive Careers, and ASE
Certification Exam With Verified Solutions
accessory system - Systems not crucial to the functioning of a vehicle, such as air
conditioner, sound system, power seats, and rear window defogger.
aerodynamics - The study of air flow around an object in motion. A major concern for
automotive designers when developing a vehicle body.
air-fuel ratio - Answer ratio by weight between the air and fuel that makes up an engine's
fuel charge
all-wheel drive - Answer type of drive system that transmits power to all four wheels at all
times. A special internal clutch in the transfer case diverts more or less power to the front
wheels depending on road conditions.
assembly - A group of fitted parts designed to serve a specific purpose.
automobile - A word derived from the Greek word "autos," meaning self, and the French
word "mobile, meaning moving. Modern-day "self-moving" vehicles blend engineering
and technology into a safe, reliable mode of transportation.
body - A skin of steel, aluminum, fiberglass, plastic, or composite carbon fiber that makes
up the outer surface of a vehicle.
body-over-frame construction - Answer vehicle design in which the body is installed over
the frame and held in place by large bolts. This design is still used on some large
passenger cars, larger vans, pickup trucks, and sport utility vehicles.
brake system - Answer a collection of components that work together to stop a vehicle
, charging system - System that is composed of battery, alternator, drive belt, voltage
regulator, charge indicator and charging harness. The task of the system is to recharge
the battery while the motor is running and supply electricity to the various electrical
systems of the vehicle.
chassis - The framework of a motor vehicle without its body panels.
Coefficient of drag (Cd) - Answer the numerical value that represents the resistance of an
object through air or water
component - Answer the smallest removable item on a vehicle. Can also be referred to as
a part.
computer system - Answer electric and electronic devices that control specific vehicle
systems
cooling system - Answer radiator and other components that allow a coolant to circulate
and maintain a constant engine operating temperature. They are also necessary to
control operating temperatures of an HV battery, motor-generator, or HV ECM circuit in
hybrid/electric vehicles.
direct gasoline injection system Answer fuel injection system that, in addition to an
electric fuel pump uses a mechanical fuel pump and high-pressure injectors to spray fuel
directly into an engine combustion chambers; also referred to as direct electronic fuel
injection.
drive train Answer all of the collective parts engine, transmission, drive shaft, differential,
drive axles, etc. that generate power and transmit it to the wheels.
emission control system - Answer a system used to decrease the volume of noxious
material released into the atmosphere from an automobile.
engine - Answer a device that converts energy into useful mechanical motion.
