: Often called the "heart" of the vehicle, it converts fuel into motion. Key internal parts include pistons , valves , and the crankshaft .
: The chassis is the frame that holds everything together. The suspension system (including shocks and struts ) keeps the ride smooth by absorbing bumps. Vital Systems for Safety and Performance
Modern vehicles are complex machines made of approximately 30,000 unique components. To understand how they work, it helps to break them down into their major systems. CAR PARTS
: Uses pads , rotors , and calipers to create friction and stop the car.
: A gearbox that uses the engine's power to change gears and drive the wheels. : Often called the "heart" of the vehicle,

: The radiator and water pump prevent the engine from overheating by circulating coolant. The suspension system (including shocks and struts )
: The catalytic converter and muffler clean emissions and reduce engine noise. Exterior and Interior Features Car Components 101: What Are Their Functions? | UTI
