On April 10th, FAW Wuxi Fuel Injection Equipment Institute's Euro IV standard integrated exhaust device “Three in One†scientific and technological achievements passed the appraisal and acceptance of Wuxi Science and Technology Bureau. This shows that the leading company in this institute has taken the lead to fill the gap in the domestic "three-in-one" scientific and technological achievements of exhaust equipment. This will break the monopoly of multinational companies in this market. This is a result of the FAW Wuxi Fuel Pumps Research Institute's implementation of FAW's “Three-year Two-Change Concept†strategic goal.
The Euro IV emission standard is scheduled to be implemented in 2010, which indicates that the post-combustion engine industry in China will enter a new stage. In order to achieve the Euro IV emission standard for vehicle diesel engines, the use of exhaust gas aftertreatment technology has become a mature international practice on the basis that the engine has reached Euro III emission standards. According to calculations, the market demand for post-discharge treatment equipment in China will reach more than 30 billion annually. At present, the SCR urea injection device, thermal energy recovery and reuse equipment, and exhaust muffler equipment used in the post-discharge treatment on the market are all independent devices in design, installation, and use. The power supply method generally adopts the fuel method or the electrospray method. , easy to produce new pollutants. Domestic manufacturers can only provide a single device, and they mainly focus on the provision of exhaust muffler devices. The FAW Wuxi Oil Pump and Tip Research Institute integrated the three to integrate the design, improved the purification efficiency, and adopted exhaust gas heat recovery technology to not cause secondary pollution, which reduced both the purification load and energy saving.
The scientific and technological achievements are mainly the use of urea-assisted injection technology to achieve the transition of nitrogen and hydrogen compounds in the engine exhaust gas from Euro III to Euro IV, using the heat of the exhaust gas to provide heating for the vehicle, and at the same time working hard to combine the heating and silencing structure. This saves the user the cost of the muffler and saves space in the vehicle. During the development of the institute, more than 10 patented technologies were formed. Compared with the traditional single device, the birth and popularity of the “three in one†exhaust device has led to a fundamental change in the concept of energy conservation and environmental protection of automobiles. The cost is 50% lower than that of foreign products, and it has good economic and social benefits. It was highly praised by the experts of the automobile factory and diesel engine factory. The reviewing experts believe that the “three-in-one†energy-saving and emission-reducing exhaust device is the first of its kind at home and abroad, and it is at the leading international level (
Evenly distributed in the high temperature resistant stainless steel seamless tube of high temperature resistance wire, dense part in gap to fill in the performance of thermal conductivity and good insulation performance are the crystallization of magnesium oxide powder, this kind of structure not only advanced, high thermal efficiency, and even heating, when high temperature resistance wire in an electric current passes through the heat to the metal surface diffusion through crystallization of magnesium oxide powder, then passed to the heated or air, achieve the purpose of heating.
