A sedan moves through the combustion and explosion of a fuel-air mixture in the cylinders, which drives the pistons in a reciprocating motion. This motion turns the crankshaft, which is connected to the transmission via the clutch. The power is then transmitted through the driveshaft to drive the wheels, propelling the vehicle. Below is a detailed introduction to how a car moves: 1. Body Composition: The car body is mounted on the frame of the chassis and is used for the driver, passengers, or cargo. The body of passenger cars and buses is generally a unitary structure, while the body of trucks usually consists of two parts: the cab and the cargo compartment. 2. Chassis Composition: The chassis is composed of the drivetrain, running gear, steering system, and braking system. The chassis serves to support and install the car engine and its various components, forming the overall shape of the car. It also receives the power from the engine to generate motion and ensure normal driving. The chassis consists of five parts: the drivetrain, running gear, steering system, suspension system, and braking system. 3. Engine Composition: The engine is the power unit of the car, consisting of 2 major mechanisms and 5 major systems: the crankshaft and connecting rod mechanism, valve train, cooling system, fuel supply system, lubrication system, ignition system, and starting system. However, diesel engines lack an ignition system compared to gasoline engines.
