Energy-saving and emission reduction set off innovations in clean diesel technology

People in the industry believe that due to the great potential for energy saving and emission reduction, clean diesel technology will continue to gain favor in the next 10 to 20 years. Nowadays, the revolution in energy conservation and environmental protection has already begun. Clean diesel technology is about to turn itself into a leader and lead the green innovation in the automotive industry. Some analysts have calculated that if the proportion of diesel passenger cars in the Chinese market grows by 1%, fuel consumption can be reduced by about 174 million liters, and carbon dioxide emissions can be reduced by about 406,000 tons, equivalent to 124,286 vehicles driving 20,000 vehicles a year. The amount of carbon dioxide emitted by the km. Assuming that since 2011, China's diesel passenger vehicles accounted for 30% of passenger cars, then 10 years later, according to the amount of possession, only one year of diesel passenger cars will save the equivalent of one Daqing Oilfield. The amount of oil. Therefore, it is extremely important to have advanced clean diesel technology for the marketing of diesel vehicles, as well as the implementation of the “National IV” standard for automobiles in the era of energy conservation and emission reduction.

In the “Replied to the Implementation Date of the Fourth Stage Limit of National Motor Vehicle Emission Standards” issued by the Ministry of Environmental Protection at the beginning of the year, it was stipulated that the national IV of light diesel vehicles was generally two years later than the gasoline engine, but the diesel technology in China did not So slow down. Looking at the domestic clean diesel technology, it can be said that the emission standards have gone ahead of the National IV. In recent years, many domestic automobile manufacturers have made breakthroughs in the research and development of energy-efficient power technology, and even some core technologies have reached the international advanced level. Inherited European pedigree, Asia's largest manufacturer of diesel powertrains, the European Power Group, the electronically controlled high pressure common rail fuel injection technology (CRDi), variable area turbocharger technology (VGT) Intercooled exhaust gas recirculation technology (EGR), through the introduction, absorption and reinvention of these three core technologies, has developed the first domestic passenger diesel engine that meets Euro IV emission standards.

According to the relevant technical person in charge of Euro-Europe, the clean diesel technology of its engine will help China's auto industry achieve increasingly stringent energy-saving goals and reduce greenhouse gas emissions. In terms of economy and carbon dioxide emissions, diesel vehicles have a significant advantage over similar gasoline vehicles. They not only reduce fuel consumption by more than 30%, but also reduce carbon dioxide emissions by about 25%. In addition, the engine's torque is increased by 50%. More powerful. It can be seen that diesel passenger cars equipped with clean diesel engines will make great contributions to energy conservation and emission reduction. Today, efforts to promote energy-saving and emission reduction in the automotive industry by vigorously promoting clean diesel technology have long been a new topic. In Europe and other developed countries, diesel vehicles have become the mainstream market trend. In Western Europe, diesel passenger cars can be seen everywhere. The proportion of diesel cars in newly registered passenger cars is about 50%. In some countries, such as France, the proportion is even as high as 70%.
