From catching up to leading Xichai to "China's strength" called Hanover
On September 19, 2018, at the " Xichai Aowei 6DM3 first with Mahler laser welding steel piston product joint conference", China's oldest power expert - FAW Jiefang Automobile Co., Ltd. Wuxi Diesel Engine Factory (hereinafter referred to as tin) Chai and the international auto parts manufacturer - Germany Mahler (hereinafter referred to as Mahler) jointly announced the world's first successful application of laser welded steel piston. The successful application of this technology makes the Xichai Aowei 6DM3 engine have stronger power, lighter weight, lower fuel consumption and longer oil change interval, marking the Xicai Aowei engine, the application of new technology. In terms of the situation, it has entered the forefront of the world; it marks that the Chinese engine represented by Xichai Aowei has entered the first camp of the world engine. Fuel-efficient and reliable Aowei shoulder international Hannover Motor Show is the world's longest, largest and most influential commercial vehicle exhibition. It is also the first stage for global commercial vehicles and parts companies to introduce new products and display new technologies. The reason why Xichai cooperated with MAHLE and chose to hold a new product launch conference at Hanover Auto Show is to show the courage of Xichai and the world-class brands to compete on the same stage, and show the ability of Xichai to serve the world's truck users (including European and American users). confidence. At present, the Xicai Aowei engine, known for its “fuel-saving, safe and reliableâ€, has fully competed with international brands, and has even led the world in local areas (such as fuel-efficient, long-term, long-term oil change). The Xicai Aowei 6DM3 first show with Mahler laser-welded steel piston products is the best proof. The product has achieved five upgrades through five “furtherâ€. One is to further increase power and torque and improve the power of the whole machine. Using laser welding technology, the cooling of the steel piston is optimized, and the piston ring groove temperature is reduced by nearly 50 ° C, which provides good temperature conditions for further power and torque. The second is to further reduce the frictional power consumption of the piston and improve the fuel economy of the whole machine. The laser welding technology can reduce the high piston compression, appropriately increase the length of the connecting rod, reduce the side thrust generated on the cylinder liner during the piston movement, reduce the frictional power consumption of the piston, and reduce the fuel consumption of the whole machine. The third is to further reduce the height of the cylinder and enhance the price competitiveness. Laser welding technology can reduce the height of the cylinder, reduce the weight of the engine and reduce the material cost. It is estimated that the direct material cost of each 6DM3 diesel engine can only be reduced by more than 100 yuan. The fourth is to further extend the mileage of oil replacement and improve the economics of the whole machine. The use of laser-welded steel pistons can optimize the temperature of the piston cooling oil chamber and the piston ring groove, avoid high-temperature gelation and aging of the oil, further extend the oil replacement mileage, and achieve an oil change interval of 100,000 kilometers or more. The fifth is to further reduce the risk of failure and improve the stability and durability of the whole machine. The use of laser welded steel piston can enhance the overall rigidity of the piston. The piston deforms less under high burst pressure, the oil consumption is more stable, and the whole machine runs more stably and reliably. Concentric alliance wins the industry doubles The cooperation between Xichai and Mahler began in 2000. From 2001, the two sides completed the expansion and expansion point. In 2002, the two sides signed a strategic cooperation agreement. Until 2018, the two sides jointly stood at the Hanover Motor Show to showcase the world's advanced technology. In the past 18 years, the cooperation between the two parties has been deepened. From aluminum pistons to steel pistons, as of 2017, the number of pistons supplied by MAHLE to the engine division has reached 5.8 million and about 900,000 sets. In the past 18 years, the two sides have adhered to the cooperative concept of "concentricity, alliance, and win-win" and formed a good friendship of mutual trust and mutual promotion. At the same time, both parties can always promote the development of enterprises with leading thinking, and gradually grow into the leader of independent technology development in the industry. Nowadays, the laser-welded steel piston products representing the world's most advanced technology have achieved the first match on the Xichai Aowei 6DM3. The standard has entered a new era and has reached a milestone. Dr. Jörg Stratmann, CEO of MAHLE Group, said that the Chinese market is one of MAHLE's most important markets. In the face of the transformation and upgrading of the automotive market, they will continue to deepen their position with the Chinese engine market, Xichai. Cooperation, create success and share the future. At the press conference, Qian Hengrong, Party Secretary and General Manager of the Engine Division, signed a strategic cooperation agreement with Dr. Jörg Stratmann, CEO of MAHLE Group. The two parties agreed to focus on cutting-edge scientific research, give full play to their respective advantages, achieve strong alliances, further enhance product and technology standards, and provide consumers with a new dynamic experience beyond expectations. Both parties agree that the excellent performance of the MAHLE laser-welded steel piston is highly compatible with the product characteristics of Xicai Aowei's “fuel-efficient, safe and reliableâ€. Xichai will apply this cooperation experience to more leading technology cooperation. Based on the existing laser welding technology, the technology of thick film DLC piston ring will be further optimized in reducing frictional power consumption and reducing carbon dioxide emissions. On the new platform products, Xichai will further apply the international advanced technology of MAHLE (oil pump, electric control pump) to build high-end power products in China and help Chinese brands to go global. Xichai Aowei 6DM3 first with Mahler laser-welded steel piston products may be a small step on the road to transformation and upgrading for Xichai, but it is a big step forward for China's internal combustion engine industry. This move by Xichai is undoubtedly a leading queue for the world to announce that Xichai will join the world's advanced technology. In the case of Mahler, Xichai is actually announcing to the world that all parts and components of advanced technology are welcome to Wuxi! Portable Type Water Well Drilling Rig
