New clean up diesel engine electronic control system technology in the foreign application rate has reached 60% to 90%. 20 beginning in the 1980s put on the market, the German company Bosch, the United States GM's Detroit Diesel Corporation, Japan Zexel company has its own products on the market. At present major companies competing to develop new products to meet emissions regulations, and market requirements. Electronically Controlled Diesel Engine technology, the development of technology to improve power from the diesel engine of the economy, the biggest impetus from the international community increasingly stringent emissions regulations. Peugeot company recently developed a new type of diesel engine decontamination systems, will be opened in recent years, the veil of its flagship car, the car will be equipped several engine, a 2.2 L of HDI diesel engine will be equipped with the unique breathing carbon filtration systems. Peugeot - Citroen company said the technology in the development of HDI engine of the new system can effectively overcome the particulate emissions from this dilemma. The system allows HDI engine emissions of carbon dioxide by 20 percent, carbon monoxide by 40%, hydrocarbons by 50%, while the particles can be reduced by 60%. Been known since the advent of the diesel engine biggest innovation. It is learnt that the particulate filter system has been adopted by France, Germany and the approval of the environmental sector, so that the technology has aroused the attention of Europe. Over the years, filtered solution is considered one of the ways in diesel engine exhaust. New filters enable HDI engine management systems and computer sensors to detect particles accumulate status, and the timely switch will automatically trigger particles burn out. Such filtering device in the next five years, if market acceptance, it will be extended to all Peugeot Citroen diesel cars and light commercial vehicles on. Particulate traps on the car had no effect on the performance of the original. HDI engine fuel consumption may rise at 5%, but performance compared with similar engines has increased by 15 per cent. This shows that the overall owners are still cost-effective. At present diesel vehicles sales in Europe to grow by about 1% a year, if as technology advances, more and more diesel vehicles acceptable to the vast number of consumers, its sales will grow by 2% to 3%, and the particulate filter system can accelerate this process. According to statistics of diesel vehicles currently account for about Europe minibus number of 25 per cent. PSA particulate filter system will be installed in the first new Peugeot car, and sales have been weak for the renewal of the Peugeot 605 series. Equipped with the filtration system DWl2TED4 models for the 2.2 L engine, up to 110.4 kW power output torque of 315 N m, than the current level of 2.5 L diesel engine performance okay.
