High pressure solenoid valve of the high pressure common rail technology make diesel fuel

High pressure solenoid valve of high pressure common rail technology make diesel fuel with dispatch blog xiao-long zhang times in recent years, high pressure solenoid valve of the automobile industry development in our country is very rapid, but along with the rapid increase of car production, energy and environmental crisis facing our country is increasingly serious. At the same time in the 12th five-year plan of support for new energy, energy saving and environmental protection industry listed in the national strategic level. Today, has a long way in the new energy technology of clean diesel engine technology is the current release the pressure from China's energy one of the most realistic low-carbon technologies. Throughout the world auto market, Europe has always been an admirer of diesel cars, penetration is already more than %, even in countries such as Poland, Austria diesel-powered cars share close %; As domestic enterprises in the continuous efforts, our country independent type clean by diesel engine has been a breakthrough technology, under the trend of energy saving and emission reduction, diesel has become the current the most realistic energy-saving models reduce the pressure on China's energy. Diesel vehicles because of its compression works on congenital than gasoline vehicles have better combustion effect, and the application of the electromagnetic valve of high-pressure common rail electronically controlled high pressure technology to further improve the fuel economy. Trucks, tractors and other old diesel engine, oil supply is not allowed because of the large pressure fluctuation, the burning effect is poor, large vibration, high pressure solenoid valve of high-pressure common rail technology effectively solve these problems. According to Asia's largest and most advanced passenger vehicle powertrain manufacturers technical personnel introduces, electronically controlled high pressure common rail fuel injection technology of injection pressure and injection process can be completely separated from each other, under any condition, this ensures that the engine can get high fuel injection pressure, this pressure can reach more than bar commonly; At the same time the high pressure oil pump high pressure fuel to the public for the tubing, by controlling the duration of high pressure oil pump electromagnetic valve opens to the public for tubing ( Common rail) Within the fuel pressure to achieve precise control, to avoid the traditional each cylinder diesel engine fuel injection respectively produced by injection volume and injection pressure are inconsistent phenomenon, make the engine run more smoothly; By ECU precisely controlled injector solenoid valve open time, duration and thus control the injection advance Angle and fuel injection quantity, ensure the minimum fuel consumption to obtain optimal power output. On the basis of the first generation of high pressure common rail technology, engineers and develop the revolutionary injection technology. It can be within a single injection process is divided into pre injection, main injection and spray after three process. Beforehand through spray can optimize the environment of combustion, preheat temperature in cylinder, reduce the vibration due to sharp fluctuations in temperature, at the same time, through the early part of the oxygen consumption, destroyed the nitrogen oxide generated by the 'high pressure oxygen enrichment' environment. And after injection, it can reduce the generation of smoke and carbon particles, enhance the level of emissions. It is understood that the first to reach the Ⅴ green diesel engine emission standard of high pressure solenoid valve, it is the application of this technology, single cycle can be realized in as many as times of injection, injection interval is only/SEC. Data shows, the use of a new generation of technology of high pressure common rail diesel engine is the most advanced in cylinder direct injection gasoline engine fuel efficiency %, emission reduction %, % higher than that of power output at the same time. Can say to guide the direction in the field of clean diesel engines for cars, and is the road to a fuel-efficient.
