The three major components of a car refer to the engine, transmission, and chassis. Below are detailed introductions about these three components: 1. Engine: An engine is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines, external combustion engines, jet engines, electric motors, etc. The engine is the heart of a car. 2. Transmission: A transmission is a device that changes the speed ratio and direction of motion. The function of the transmission is to vary speed and torque, ensuring that the power output from the engine can meet the car's needs under any operating conditions. 3. Chassis: The chassis refers to the combination of the car's powertrain, running gear, steering system, and braking system. It supports and installs the car's engine and its various components and assemblies, forming the overall shape of the car, bearing the engine's power, and ensuring normal operation.
