Anatomy of a Car

This section provides an overview of the major systems in a vehicle, including the Body and Frame, engine, transmission, suspension systems, wheels and tires, control systems, electrical systems, engine subsystems, and climatic equipment.

Body and Frame

• The body provides space for passengers and cargo.

• The frame is the main supporting structure to which all components are attached.

• Modern cars mostly use unibody construction combining body and frame functions.

Engine

• Converts energy into mechanical energy for propulsion.

• Internal combustion engines are common but electric and hybrid motors are gaining popularity.

• Engines have subsystems like intake, exhaust, fuel supply, cooling system.

Transmission

• Connects engine to drive wheels transferring torque.

• Manual gearbox requires gear shifting by driver; automatic gearbox shifts without driver intervention.

• Different types of wheel drives impact transmission structures.

Car Assemblies: Body and Frame

This section delves into the details of car assemblies focusing on the Body and Frame components.

Body

• Provides space for occupants and cargo with auxiliaries and decorative elements.
