The advantages of clean diesel technology are no longer strange to many people, but quite few people really have a deep understanding of it. When talking about this topic, we can, in fact, transform the original very abstract preach into figures that are tangible, visible and audible -- when clean diesel engines are gradually migrated from commercial cars to passenger cars and then generally used in the passenger car field, there will be many people who feel surprised: So that amazing results of energy saving and emission reduction can be achieved by only updating traditional diesel engine technology. Suppose the annual increasing number of passenger cars in China is 10 million in which the diesel cars take up 30 percent, the volume of energy consumption saved in over two years will be equal to the annual output of Daqing Oilfield.

According to a report released recently by National Energy Administration, this year the net import volume of oil is expected to reach up to 210 million tons, 5.5 percent higher than that in 2009. Another data that deserve special attention is: China's dependence on imported oil has reached more than 50 percent. It has become a strategic issue concerning national energy security.

On the one hand, the economic development is highly dependent on oil and other energy sources; on the other hand, we have to face the handicap of high pollution emissions. Energy saving and environment protection have undoubtedly become the inevitable choice.

For recent decades, the development of new energy automobile has almost become a common selection for global automotive manufacturers; the investment on research and development of new energy automobile in all countries is not only huge, but continuing. Meanwhile, the large-scale industrialization of new energy automobile still has a long way to go.

It is no doubt that new energy automobile is the automotive industry's future direction. Traditional energy sources will finally be replaced by new energy resources in the automotive field, whether it is gasoline or diesel. However, we should objectively see that traditional power automobile will remain the mainstream in the market for a long period of time in the future. After all, so far, the new energy automobile technology has not developed as mature as that of traditional automobile. There are still new technical difficulties needing to overcome. Meanwhile, as a new thing, multi-mode and route need to be continuously tried and explored to achieve commercialization.

However, there is no time to waste for energy saving and emission reduction. We can see that some European countries are not only actively engaged in the exploration of new energy automobile technology, but also vigorously promoting the use and popularity of clean diesel automobile, taking the promotion of clean diesel automobile as an important tool for the energy saving & emission reduction and environmental protection of the automotive industry.

The experience of some mature European automobile markets has shown that before the perfection of new energy technology and realization of large-scale commercialization of products, clean diesel technology has more obvious advantages than gasoline technology. In the aspect of oil saving, a diesel engine with equal displacement to a gasoline engine can save oil by 30 percent, raise the torque by 50 percent and reduce carbon dioxide emission by 25 percent. It can be seen that to promote clean diesel automobile can not only reduce resource consumption greatly, but also effectively protect the environment and practically reduce carbon emission.

In Europe where environmental standards are the most demanding in the world, there is large-scale use of clean diesel passenger cars, fully illustrating that diesel vehicles can not only save energy, but also the emission level of them is adequate to meet the strict EU regulations. Those who do not quite understand clean diesel automobile due to the facts of black smoke and loud noise of former diesel automobiles should see the daylight from the clean diesel cars running on the streets and alleyways in the EU members.

For China's automobile production enterprises, the vigorous development of new energy automobile gives us the opportunity to stand on the stage of global automotive industry's competitiveness to work together with internationally large-scale automakers for achieving a better future; but we must also go to wait and to get perfect with full preparation. At present, what should be also taken into account is how to take on social responsibility as an automobile company in the context of energy saving and emission reduction, a question which is also worth pondering. In this aspect, OED Engine Co., Ltd spares no effort to take environmental protection and energy saving as a primary responsibility for business development. It invested more than RMB 2 billion yuan to integrate global leading technologies and aiming at the great advantage and potential market of clean diesel engine, it developed and produced the world leading clean diesel engine. This type of clean diesel engine, which integrates several advanced technologies, will no doubt contribute its efforts for the sustainable development of automotive industry.
