On July 1, 2013, the four emission standards for heavy-duty diesel vehicles were formally implemented. In the past two months, we are delighted to see more and more cities joining the four camps of the country. At the same time, the industry and some enterprises dedicated to energy conservation and environmental protection are also developing and manufacturing products that meet the national IV emission standards. .
National IV implementation is a systematic project. Upgrading of emission standards puts higher requirements on various components of the engine. As an important engine component, the filter plays an important role in protecting the fuel system and prolonging the service life of the fuel system. effect. High-quality filters are used to guard and monitor the fuel system, which can make better use of the engine's energy-saving and emission-reducing effects. So what are the new requirements for the filter for emission upgrades in comparison with the second and third stages in the country? What kind of filter products do we need in the four times?
High-precision filter products help the four times
Wang Yu, general manager of Suzhou Industrial Park Dafeite Filtration Technology Co., Ltd., told reporters: â€œThe three stages of the country are an important watershed for engine filtration technology. Previously, diesel engines were mostly mechanical injection systems. After entering the country three, they were controlled by electronically controlled injection. As the representative of the system, due to the characteristics of the electronically controlled injection control system, the fuel needs to be fully burned to ensure that the entire engine injection pressure will be further increased, the injection flexibility will be further increased, the engine operation will be more stable, and the noise will be further reduced. However, due to the high level of fuel impurities used in China at this stage, a high-precision filtration system is needed, which fully guarantees the normal operation of the electronically controlled fuel system and objectively reduces the amount of impurities entering the cylinder to ensure full combustion of the fuel. ."
"In addition to filtering mechanical impurities in diesel fuel, diesel filters also have an important function of filtering water. The presence of water is extremely harmful to the diesel fuel supply system. Corrosion, wear, and damage to the cylinder piston rings may even cause cylinder pull-ups. It may also deteriorate the combustion process of diesel fuel.The diesel fuel filtration system uses the fluid flow control technology according to the different liquid densities to separate the water and achieve the effect of water filtration, so that the fuel burns more fully and effectively protects the common rail system. Jade continued to say.
In addition, the development of diesel filtration technology to date, the filter itself also has a lot of automation technology. Wang Yu said: "We are not only concerned about the filter and engine matching issues, but also pay attention to the development of the corresponding electronic accessories, which further improve our low-pressure fuel filter system, some work to protect the user to enjoy the best quality filter Cleaner products.
Time filter caused by the filter industry calls its own brand
In the fourth national era, what kind of filter products do we really need? For users, no one can reject the "high quality and low price" products. However, as far as the industrial environment of China's filters is concerned, because the core technologies of the filter products have long been dominated by foreign brands, subject to the level of research and development and production consistency, Chinese domestic filter suppliers rarely provide real In the sense of "quality and cheap" products.
Domestic OEMs are increasingly able to accept filters from foreign companies or joint ventures, and it is difficult for foreign-owned OEMs to enter Chinese filter companies, resulting in the vast majority of vehicles and engine matching markets being used by foreign companies. leading. Especially after China raised its emission standards, many filter manufacturers lacking core technologies face the dilemma of closing down or being acquired, but this also gives opportunities to some independent brands that have the courage to introduce advanced technologies and continue to innovate.
Daphite is such an example. Wang Yu introduced to reporters: â€œThrough technical cooperation with multinational Delphi, we stand on the shoulders of giantsâ€™ technology to correct and improve our technology, improve our understanding, and increase our awareness. Effectively organize our production.In the past three years, our cooperation has been very good, and it is indeed helpful to improve our R&D, production, and manufacturing technologies.
"Now, I can say that we are really the core technology, in a word, that is, I can produce 1 million filters, the first and the 1 million is just the same. In the future, we will also explore and seek Further introduce Delphi's advanced technologies and products to enrich our product lines, such as our Euro 6 emission filter technology, etc. Of course, we will continue to absorb and improve and innovate to improve product quality and reduce prices. Make Daffett products closer to the Chinese market and users.â€
With the increase of vehicle ownership, the increase in vehicle production, the shift of global procurement to China, and the rapid development of commercial vehicles in China, it has brought unprecedented opportunities for the development of the domestic filter industry. In the post-market, China's filter market is widely expected. Especially in the National 4th era, we are looking forward to having more space for independent brands with high quality products and advanced technologies represented by Daphne.
