Here we introduce five major components: the engine, the drive- train , suspension, the car body and the electrical system. Engine The engine is called the power unit and it is the source of power that makes the car move. It includes engine management, crankshaft assembly, engine lubrication, engine cooling, exhaust system and air system. Drive-train The drive-train is a very important part of the vehicle. It is the power transfer assembly. It transfers the power from engine into wheels. It has clutch system, gearbox, propeller shafts, and final- drive unit. Suspension The suspension is the under portion of an automobile. Its the frame of the vehicle and supports all of the major parts. It has two parts: front suspension and rear suspension. It contains brakes, wheels, and tires. Body It is the support and load-bearing structure. The car body can protect the engine, the driver, the passengers and goods. There are windows, doors, hood, side- impact protection and frame. The electrical system The electrical system supplies electricity for many parts , such as the lighting system and ignition system, data-transmission system, and the comfort and convenience system . These five parts are closely related to one another. When something unusual happens, you should check the parts carefully to find out where the trouble comes from and take some measures to solve it.
