A truck is a commercial vehicle designed and equipped mainly for carrying goods, whether it can tow a trailer or not.
Trucks are generally called trucks, also known as trucks, which refer to cars that are mainly used to transport goods, and sometimes refer to cars that can tow other vehicles, belonging to the category of commercial vehicles. Generally, according to the weight of the car, it can be divided into heavy and light. Most trucks use diesel engines as power sources, but some light trucks use gasoline, liquefied petroleum gas or natural gas.
Truck, whose official name is truck, is a kind of vehicle used to carry goods and commodities, including dump trucks, tractors, off-road and off-road trucks, and various vehicles specially manufactured for special needs (such as car ferries, fire engines and ambulances, tank trucks, container tractors, etc.). ). See English-Chinese truck dictionary and truck atlas.
In fact, the classification of trucks in China society is very confusing, and some of them are classified according to the total mass and the exhaust capacity of useful engines. The new national standard "Terms and definitions of automobile and trailer types" divides trucks into commercial vehicles, which are subdivided into: general trucks, multi-purpose trucks, full trailer tractors, off-road trucks, special work trucks and special trucks.
A car usually consists of four parts: engine, chassis, body and electrical equipment.
