How many car parts? Actually, this is not a very precise standard answer ...
 
It is estimated that about independent car parts are generally made more than 10,000 non-dismantling assembled. Structure is extremely complex special vehicles, such as F1 racing, the number of independent components which can reach as much as 20,000.
 
Of course, no one can accurately estimate the number of components of a car calculated. The more the number of parts of the car, the car does not mean better performance, but means that it will be more difficult to ensure reliability.

car engine
 
Automobile engine is the power plant, mainly by the body, crank linkage, valve, cooling system, lubrication system, fuel system and ignition system (diesel engine no ignition system) and other components.
1) Cooling: Usually the water tank, water pump, radiator, fan, thermostat, water temperature and turn on the water switch. Automotive engine cooling using two methods, namely, air cooling and water cooling. General use of an automobile engine antifreeze cooling.
 
2) lubrication system: engine lubrication system by the oil pump, set filters, oil filters, oil channels, pressure limiting valve, oil table, a sense of tamponade and dipstick other components.
 
3) Fuel system: gasoline engine fuel system from the fuel tank, fuel gauge, fuel pipe, fuel filter, fuel pump, fuel injectors, air filter, intake manifold and other components.
 
4) ignition system: from the ignition power supply, ignition switches, ignition coils, spark plugs, high-voltage Eng composition.
 
Car chassis
 
The main chassis of the vehicle by the transmission system, driving system, steering system, brake system components.

1) Drive Train: mainly by the clutch, transmission, universal joints, drive shaft and drive bridges components.
 
The clutch is the engine's power and smooth gear engagement or temporarily separated for auto start, stop, shift and other operations on the driver.
 
The transmission by the transmission case, the transmission cover, the first shaft, a second shaft, intermediate shaft, reverse shaft, gears, bearings, and other parts constituting the control mechanism for the car speed change, the output torque becomes.

2) driving system: the frame, axles, suspension and wheels and other components, its basic function is to support and ensure the quality of the whole car with the car.
 
3) leaf springs and shock absorbers: the role of the leaf spring is to maintain the flexibility of the link between the body and the frame and wheels or axles. The role of shock absorber is to be eased when the vehicle is subjected to shock impact. Shock absorbers and leaf springs in parallel.
 
4) Steering system: steering wheel, steering gear, steering knuckle, knuckle arms, tie rod, drag link, etc., the role of the steering.
 
5) wheel alignment: In order to keep the car stable straight running, turning light, reducing automobile tires in motion and steering mechanical wear and tear, the front wheel, kingpin, the front axle is installed between the three has a relative position this is called "wheel Alignment." It includes rear caster, pour in the production and marketing, front toe. Toe-value refers to the front edge of the front wheel is smaller than the distance between the two edge distance difference.
 
6) Braking system: the braking system is to enable a vehicle to a driver in accordance with the requirements of compulsory deceleration or even stop; making cars have been suspended under various road conditions (including on the ramp) stable parking; so downhill vehicle speed remains stable. Currently various domestic automobile manufacturers to use in small and medium car finished goods more for Qianpanhougu brake systems, some models of four-wheel disc brakes, with respect to the drum brakes, disc brakes more advanced technologically braking performance is more excellent.
 
Auto Body and Accessories
 
Auto body effect is mainly to protect the driver and constitute a good aerodynamic environment. Automobile body structure Formally speaking, divided into non-bearing, bearing, semi-bearing type. Automotive body component parts including the engine cover, car roof, trunk lid, fenders, dash board.

1) engine cover: engine cover in the general structure of the outer and inner plates sandwiching with insulating material, a rigid inner plate serve to strengthen the role of its geometry selected by the manufacturers basically skeleton form. When the hood is open generally turning back, there is a small part of the forward flip.
 
2) between the cover: engine cover in the general structure of the outer and inner plates sandwiching with insulating material, a rigid inner plate serve to strengthen the role of its geometry selected by the manufacturers basically skeleton form. When the hood is open generally turning back, there is a small part of the forward flip.
 
3) boot lid: the trunk lid also has an outer and inner plates, the inner panel reinforcing ribs. Some are called "two and a half car" car, its trunk extending upward, including rear windshield included, so the opening area increases, the formation of a gate, so-called back door, both to maintain a sedan shape and can easily store items.
 
4) fenders: fender covering the wheel exterior body panels, due to the old part of the body shape and position of birdlike wings named. Follow the installation position is divided into the front fenders and rear fender, front fender mounted on the front wheels, it is necessary to ensure the rotation of the front wheel and when the maximum limit space beating, then no rotation of the wheel fender grazing question, but out of consideration for aerodynamic rear fenders bulge outward slightly arched arc. Some current car fender and the body has become a whole body.
 
5) dash panel: dash panel refers to the bulkhead between the engine compartment and the car, which floor and front pillar connection, install auto body, under the dash on the cover. Dash board has a plurality of openings, as cable, rod, tubing and wire harness maneuvering through use, but also with the pedal, square columns and other machine parts ask the installation location.
 
Electronic and Electrical
 
Automotive electronic control device is a generic term automobile body electronic control devices and on-board vehicles.

Vehicle electronic control device comprising: an engine control systems, chassis control systems and body electronics control systems. These are the MPU consists of sensors, microprocessors, actuators, dozens or even hundreds of electronic components and component parts of the electronic control system.
 
Car Automotive electronic device comprising: a battery, a generator, a regulator, starter, ignition system, instrumentation, lighting, audio device, wipers and other components.
