Answer these discussion questions using the textbook:

1. Identify and describe primary automotive assemblies and major automotive systems.

Read the chapter summary below:

■ The body and frame support, stop, and enclose the vehicle.

■ The engine provides dependable, efficient power for propulsion and electrical systems.

■ The computer system uses electronic and electrical devices to monitor and control various auto assemblies.

■ The fuel system provides the correct mixture of air and fuel for efficient and complete combustion.

■ Electrical systems operate the electrical-electronic circuits, components, and devices, as well as propulsion in hybrid vehicles.

■ The cooling system maintains a constant operating temperature for improved combustion efficiency.

■ The lubrication system reduces friction between moving parts inside the engine.

■ Emission control systems reduce air pollution produced by the vehicle.

■ Drivetrain systems transfer turning force from the engine crankshaft and/or the motor-generator to the drive wheels.

■ Suspension, steering, and brake systems support and control vehicle handling, maneuvering, and deceleration.

■ Accessory and safety systems increase passenger comfort, safety, security and convenience.

■ A hybrid electric vehicle uses two methods of propulsion—an internal combustion engine and an electric drivetrain.
