The Automobile

Steam car-refers to power device drivers, or Traction on the road, For workers with or used for transport by Load items and the project designed Assignment of wheeled vehicles ,The car is by all sorts of institutions and the device component.Although the various agencies, loadingThe structure and installation for position DuoZhong diversity,But the overall structure and the structure of the main partsHave the same basic rules and similar job.

automobile basic structure By the following four on the whole car composed of: 1, engine: car power unit，will fuel in gasThe heat energy produced is burning in cylinder into a

machineSoldiers, and then through the chassis of the power transmissionSystem driver the car. 2,bottom plate: will transfer the power of the engine output to floodingDongLun, to make the car produce movement, and insuranceCard moving. 3, car body: to take personnel, loading goods, installation engine, chassis of each system and electrical appliancesEquipment 4, electrical equipment: provide power supply, starting the engine, pointBurning fuel, monitoring work operation condition,Lighting, improve the driving safety, fuckThe stability and comfort, and so on.

Auto parts of component and function As stated above, the car was generally by the engine,Chassis, body and electric equipment form, 3

and four mostThe type of power device used car, for the car agenciesDevice structure and the structure of the decisive impact. At present the bigMost car was by the internal combustion engine and piston-type asPower unit, so we mainly discuss reciprocating pistonThe structure of the internal combustion engine car and work principle. 1, engine The engine is the power unit of the car, action is will fuel in cylinders from the burning of heat energy into Mechanical power, then through the chassis of the transmission system flooding.Move the car. The engine crank rod system, with gas institutions, Fuel supplies are, the lubrication system, cooling, department of ignition, department of Seven parts of starting. 2, bottom plate The chassis is the role of the engine output still force transfer to the drive wheels, that car produce movement,And ensure the normal running.By the transmission, driving chassis is, steering system and brake system composed of four. 3, car body The car body structure is mainly including body shell,Body metal sheet and the door, window glass, the body Inside and outside decoration, car accessories, seat and ventilation,Air conditioning, etc.Body to take personnel, loading goods,Installing, chassis of each system and electrical equipment 4, electrical equipment Electrical equipment of the function is to provide power supply, car started The engine, fuel, monitoring work lit operation condition, lighting,Improve the driving safety, handling stability and comfort, etc. Now automotive generally used 12 V dc low voltage power supply,Battery and generator two dc power parallel to the power equipment Provide dc, on the car all kinds of electrical equipment and power are parallel Connection. All the electrical equipment using wired system connection, 4

namely,With only a root positive wires, and negative and parallel into the frame, etcMetal body is linked together, commonly known as "take iron".

Inspection and maintenance electronic engine maintenance points (1) Accused of petrol injection system of gasoline cleanliness requirements of high grades and quality should be used fully meet the requirements of leaded gasoline. The fuel filter to change regularly, in order to prevent the fuel injectors foreign bodies blocked. (2) In strict accordance with the use of the power supply requirements. Install the battery must be correct, or when the polarity electronic components will be burned to the ground. (3) To avoid as far as possible by violent vibration, and computer to prevent moisture in the electric control system (department) in a zero. (4) In the battery electric lead to a deficit not normal engine starting, it shall promptly to the battery or replacement of the battery, and try not to use the method to pick up circuit across starting the engine. (5) Do not wash with water microcomputer control unit and other electronic devices. Place the environment humidity storage engine shoulds not be too big, as far as possible in the summer without water scouring the floor. (6) Prevent the microcomputer system by severe mechanical shock vibration. (7)The engine to stay away from the electrical equipment of the electromagnetic field can launch, avoid space of the microcomputer system of strong electromagnetic interference.
