14 pin 776267-5 Car Waterproof Connector Connector Blue Curved Needle Holder Integrated Controller

1) Power system. Today's automotive power systems are primarily composed of batteries, alternators, and electronic regulators. In the car, the battery and the generator work in parallel, and the electrical and electronic equipment of the vehicle are connected in parallel with two DC power sources. The function of the power system is to provide electric energy to the electrical equipment of the vehicle.

2) Start the system. Electromagnetically controlled starting systems are generally used in automobiles, which are mainly composed of starters, starting relays and ignition start switches. The function of the starting system is to start the engine.

3) Ignition system. The gasoline engine is equipped with an ignition system. At the end of the compression stroke of the diesel engine, the temperature of the inhaled air in the cylinder has exceeded the ignition point of the diesel, and the mist diesel sprayed from the injector will burn immediately when it encounters hot air, so there is no need to equip an ignition system. . The function of the ignition system is to generate a high-voltage electric spark to ignite the combustible mixture in the cylinder.

4) Information display system. It is mainly composed of various sensors, indicating instruments, warning lights and electronic display devices. Sensors include engine lubricating oil pressure sensor and coolant temperature sensor, fuel tank oil level sensor, vehicle speed sensor and engine speed sensor, etc. Indicating instruments include ammeter, voltmeter, oil pressure gauge, temperature gauge, fuel gauge, speedometer and engine tachometer, etc. The warning lights mainly include low engine lubricating oil pressure warning light, high coolant temperature warning light, low fuel tank oil level warning light, low tire pressure warning light, low brake pressure (oil pressure or air pressure) warning light , Brake fluid level is too low warning light and various electronic control system failure warning lights, etc. Electronic display devices include light-emitting display devices, line graphic display devices, and liquid crystal displays. With the wide application of electronic technology in automobiles, the electronicization of automobile instrumentation has become the development trend of displaying automobile information. The function of the information display system is to monitor and display the operating parameters of the vehicle, especially the engine operating condition parameters and limit parameters, so that the driver can take timely measures to prevent personal and mechanical accidents. 

5) Lighting and signaling system. It is mainly composed of various lighting devices inside and outside the car, and its function is to provide lighting necessary for safe driving at night or in foggy weather. Among all lighting devices, the headlight is the most important lighting device. The signal system consists of various signal lights, flashers, electric horns and buzzers, etc., such as police cars, ambulances and fire engines, etc., all need to be equipped with audio warning devices. The function of the signal system is to provide the necessary instructions and warning signals for safe driving.

6) Auxiliary electrical system. Mainly include windshield wiper and washing system, window glass lifting system, seat position adjustment system, air intake preheating system, etc. The function of the windshield wiper and washing system is to scrape off rain, snow, dust and dirt on the windshield, so as to provide the driver with a good view and ensure driving safety. The function of the window glass lifting system is to control the automatic lifting of the window glass to improve the convenience of use. The function of the seat position adjustment system is to adjust the front, rear and height positions of the seat. The function of the intake preheating system is to preheat the air or combustible mixture entering the cylinder to ensure the engine starts quickly. With the development and progress of control technology, more and more auxiliary electrical devices are used in automobiles, mainly for comfort, entertainment and safety.

7) Power distribution device. Including various control switches, distribution harnesses, safety devices (fusible links, fuses, circuit breakers), relays, connectors and central junction boxes, etc. The function of the power distribution device is to connect the electrical appliances and electronic equipment of the entire vehicle into an organic whole according to the connection principle of the entire vehicle circuit, so as to realize the different functions of the electrical appliances and the electronic control system.
