1, engine. It is the power device of the automobile, and its function is to make the fuel that enters it burn into heat energy, then into kinetic energy, and drive the automobile through the transmission system of the chassis.
2. Chassis. The role of the chassis is to support the car body, accept the power generated by the engine, and ensure that the car can run normally. The chassis itself can be divided into four parts: transmission system, driving system, steering system and braking system.
3. the body. Refers to the part of the vehicle used for carrying people and loading, and also refers to the whole vehicle. Automobile body structure mainly includes body shell, doors, windows, front sheet metal parts, interior and exterior decorative parts and body accessories, seats, ventilation, heating, air conditioning and so on. Trucks and special vehicles also include carriages and other equipment.
4. Electrical equipment. Including power supply, engine starting system, automobile lighting and other electrical equipment, as well as the ignition system of the engine in the forced ignition engine.
How to choose an automobile engine?
1, dynamic.
Dynamic performance will directly determine the acceleration time, acceleration time and maximum slope of the car. The dynamic performance indexes of the engine mainly include maximum power, maximum torque and speed. Generally speaking, the greater the maximum power P and maximum torque T, the stronger the engine power.
2. Economy.
Under the policy background of stricter emission regulations, the economy of engines has also become the primary factor for major automobile manufacturers to consider. The economic indicators of the engine mainly include effective thermal efficiency and fuel consumption rate.
As ordinary consumers, emission regulations are not the main factor for personal consideration, but the economy of the engine is closely related to its power performance, which also directly affects our car purchase budget and later maintenance costs, so the economy of the engine is also a factor that we can't ignore.
3. New engine technology.
Before buying a car, you can also pay due attention to the new technology adopted by the engine.
