Domestic passenger car application solenoid valve high-tech close the gap between the world's advanced passenger car

Domestic passenger car application of electromagnetic valve of new and high technology close the gap between the world's advanced passenger bus application solenoid valve technology sina admin time now, is widely used in domestic passenger car of high and new technology ( Solenoid valve technology) Mainly includes the following aspects: new technology, new devices. A, electronic-controlled gasoline injection system electronic-controlled gasoline injection system its advantage is to achieve accuracy control of the air and fuel ratio. Using multi-point sequential injection separately to each cylinder inlet port fuel injection, each cylinder air-fuel ratio deviation is very small, the engine can work under a thin mixture; The oxygen sensor closed-loop control can further improve the control accuracy of air-fuel ratio; Temperature, pressure change in car running region, and launch, warming-up, accelerating transition conditions, such as air-fuel ratio can be corrected in time complement, and can automatically cut off oil, slowing and idle speed control system, make can get the best air-fuel ratio under various working conditions. In the system there is no problem of mechanical drive, the device can be scattered layout, install not restricted in the engine. Using multi-point injection mode, can according to the optimal admission line charging efficiency and reasonable design, make full use of the intake of inertia supercharging, increase the output power of the engine. Therefore, the use of electronic control fuel injection system of gasoline engine, comprehensive performance improved significantly. Compared with the traditional carburetor engine, an electronically controlled gasoline injection system of the engine power increase % ~ %, fuel consumption reduce % ~ %, reduce exhaust emissions of harmful substances more than %; Because the torque performance improvement, fast transient response, vehicle acceleration is greatly increased; Cold car start easier, warming up more quickly, and can well satisfy the current society to reduce emissions, reduce consumption and increase power and improve the driving performance requirements. Electronically controlled gasoline injection system is mainly composed of air intake, fuel, electric control system composition. Electronic control unit (ECU) for main components including ECU, air flow meter, passing on the intake manifold pressure, fuel gauge, fuel injector, fuel pressure regulator, throttle valve, etc. The first page of the first page, pp
