New clean up the diesel engine electronic control systems in foreign countries application rate has reached 60 percent to 90 percent. In the 1980s started on the market, the German company Bosch, the United States of GM Detroit Diesel Corporation, Japan Zexel and other companies have their products on the market. At present major companies competing to develop new products to meet the emission regulations and market requirements. Electronic diesel technology, the development of its technology to improve engine power from the economy, the biggest impetus from the international community increasingly stringent emissions regulations. Peugeot company recently developed a new type of diesel engine clean up systems, will open its flagship vehicles in recent years, the veil, when the number of car equipment in the engine, a 2.2 L of the HDI diesel engines will be fitted with a unique Breathing carbon filtration system. Peugeot - Citroen company said the technology in the HDI engine on the development of the new system can effectively overcome the problem of particulate emissions. The system enables HDI engine emissions are reduced by 20 percent of carbon dioxide, carbon monoxide by 40 percent, hydrocarbons by 50 percent, while the particles can reduce the 60 per cent. Since the diesel engine was known since the advent of the greatest innovation. It is learnt that particulate filter system has been adopted by France and Germany the two countries approved the environmental sector, so that the technology has aroused the attention of Europe. A long time, the filter is considered resolved one way to diesel engine exhaust. New filters can HDI engine management system for the computer and sensors detect particles accumulated situation and timely switch will automatically trigger particles Shaojin. Such filtering devices in the next five years, if recognized by the market, it will be extended to all of Peugeot, Citroen diesel cars and light commercial vehicles on. Particulate traps on the performance of the original car has no impact. HDI engine work at the fuel consumption may rise 5 percent, but with similar engine performance has improved compared to 15 percent. This shows that the overall owners are still cost-effective. At present diesel vehicles in Europe sales grow at an annual rate of about one percent, if as the technology advances, more and more diesel vehicles acceptable to the majority of consumers, its sales will grow by 2 percent to 3 percent, and particulate filter system can speed up This process. According to statistics of diesel vehicles in Europe about the current number of passenger cars 25 percent. PSA particulate filter system will be first installed in the new Peugeot cars, 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, the output power of up to 110.4 kW, torque up to 315 N • m, than the current level of 2.5 L diesel engine performance okay.
