In recent years, China's automobile industry has developed very rapidly, but with the rapid increase of automobile production and sales, China is facing an increasingly severe energy and environmental crisis. At the same time, the support for new energy, energy conservation and environmental protection industries in the 12th Five-Year Plan has been included in the national strategy level. In the new energy technology has a long way to go today, clean diesel engine technology is the most realistic low carbon technology to ease the pressure of China's energy.
Throughout the world car market, Europe has been the favor of diesel cars, the penetration rate has already exceeded 50%, in Poland, Austria and other countries diesel car share even close to 80%; With the continuous efforts of domestic enterprises, China's independent clean passenger diesel engine technology has made a breakthrough, under the trend of energy conservation and emission reduction, diesel vehicles have become the most realistic energy-saving models to relieve the pressure of China's energy.
Diesel vehicles inherently have better combustion effect than gasoline vehicles because of their compression ignition working mode, and the application of electrically controlled high pressure common rail technology further improves fuel economy. Old diesel engines such as trucks and tractors have poor combustion effect and vibration due to large pressure fluctuation and inaccurate fuel supply, etc. High pressure common rail technology has effectively solved these problems.
Euro-German 2.0L diesel engine
According to Asia's largest and most advanced passenger vehicle powertrain maker the serie DE power group 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 1600 bar commonly; High pressure oil pump at the same time the high pressure fuel to the public for the tubing, by controlling the duration of high pressure oil pump electromagnetic valve to open to the public for tubing (common rail) within the fuel pressure to achieve precise control, 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; Through the ECU precise control of the injector solenoid valve opening time, duration to control the injection advance Angle, fuel injection volume, to ensure that the minimum fuel consumption to obtain the most ideal power output.
On the basis of the first generation of high pressure common rail technology, engineers developed a revolutionary multiple injection technology. It can be a single cycle injection process is divided into pre-injection, main injection and after the injection of three processes. The combustion environment can be optimized by preheating the temperature in the cylinder in advance, which reduces the vibration caused by the sharp fluctuation of temperature. At the same time, the high-pressure oxygen-rich environment generated by nitrogen oxides is destroyed by consuming part of oxygen in advance. After the injection, it can reduce the generation of soot and particulate matter, and improve the emission level. It is understood that the first to reach the Ⅴ diesel engine emissions standards of the meaning, green, it is the application of the technology, the single cycle it can achieve up to 4 times of injection, the injection interval is only 1/100000 of a second.
Data show that the use of a new generation of high pressure common rail technology Euro-Italian German green diesel engine than the current most advanced cylinder direct injection gasoline engine fuel saving 30%, emissions reduce 25%, while the power output 50% higher. It can be said that clean diesel engine has guided the direction for the car field and is a fuel-saving road.
