The eight countries' IV series products independently developed by FAW Jiefang Company Wuxi Diesel Engine Factory passed the provincial-level new products of Jiangsu Province and the scientific and technological achievements of Wuxi City on December 6, 2010 respectively. The members of the expert group of the appraisal committee unanimously believed that the eight countries' IV series products passed independent research and development and had independent intellectual property rights. The whole machine technology reached the domestic leading level and could be put into production.
The appraisal of the new products of the 8 countries IV not only marks that FAW Group has formed series IV products based on Aowei engines, but also marks a new breakthrough in independent research and development technologies of the Group's engines and increased market competition. Advantage chips. According to reports, after passing the technical results appraisal, the eight-country IV series of FAW-liberated Wuxi diesel engine plant will give full play to the advantages of the advanced production base and market network, as well as the influence of the brand, accelerate the transformation of scientific and technological achievements, and rapidly form scale. Production and further expand market share through nanny services.
Experts at China FAW's CA6DN, CA6DM, CA4/6DL, and CA4/6DF IV Series Diesel Engines held at Xichai believed that Xichai CA6DL1, CA6DL2 series IV diesel engines use high pressure common rail + SCR and high pressure common rail + EGR + POC The two national IV technical routes were independently researched and developed. Through scientific and technological appraisal, the use of electronically controlled cooling EGR technology on medium- and heavy-duty commercial vehicles to achieve national IV emissions was an innovative result. Xichai Eight Countries IV series products passed the provincial level in Jiangsu province Product identification and identification of scientific and technological achievements in Wuxi City.
The appraisal committee composed of experts from more than ten domestic high-level research institutions including experts from the China Internal Combustion Engine Institute has reviewed the technical documents of the eight countries' IV series products, heard technical project reports, conducted on-site assessment of diesel engine prototypes, diesel engine performance and emissions. With regard to the random test, as well as the questioning and defense of related technical issues in the eight countries' IV series products, the expert group has highly evaluated and affirmed the technology of the eight countries' IV series products. The appraisal committee unanimously held that the eight countries' IV series products are mature and reliable, and have good application prospects and promotion conditions. In particular, the national IV series diesel engines such as CA6DN1, CA6DM2, CA6DL, and CA4DL1 adopt the SCR technology route and have applied the most advanced domestic technologies. Electronically controlled common rail diesel engine OBD calibration technology; CA6DL1, CA6DL2, CA6DLD and Other national IV series diesel engines have adopted SCR and EGR+POC dual technology routes for independent development, and applied the most advanced electronically controlled common rail diesel engine OBD calibration technology in China. The three-high vehicle calibration, emissions have reached the national IV standard requirements. The expert group of the appraisal committee stated that the eight countries' IV series products have passed independent research and development and have independent intellectual property rights. The whole machine technology has reached the domestic leading level, and they all agreed to pass the provincial new product appraisal of Jiangsu Province and the scientific and technological achievements appraisal of Wuxi City and can be put into production.
The eight national IV series diesel engines passed this certification are all adopting high-voltage electronically controlled common-rail fuel injection system. The power coverage can reach 130-500 hp and the maximum rail pressure can reach 180 MPa. The newly developed combustion system can ensure the efficient and clean burning of fuel. Compared with similar products, the major performance indicators of the products are at the international advanced level. The appraisal of the new products of the eight countries IV not only marks that FAW has formed series IV products based on Aowei engines, but also marks a new breakthrough in the independent R&D technology of FAW engines and increases the competitive edge of the market. .
