[Hanover] Sino-Western 璧 璧 炼 钢 钢 钢 柴 奥 奥 首 首 首 首 首 首 首 首 首 首 首 首

As we all know, 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. At the Hannover Fair, the FAW Jiefang Engine Division and the German Mahler Company jointly announced that the Xichai Aowei 6DM3 was first released with the MAHLE laser-welded steel piston, and the world's first laser-welded steel piston was successfully applied. The successful application of this technology indicates that the Xichai Aowei engine has entered the forefront of the world in the application of new technologies.

Assistant to the Minister of the FAW Liberation Business Division, Assistant General Manager of the Liberation Company, Party Secretary and General Manager of the FAW Jiefang Engine Division Qian Hengrong, Deputy General Manager of FAW Jiefang Engine Division Huang Chenghai, Hou Fujian, CEO of the German MAHLE Group Dr .Jorg Stratmann, Executive Vice President Anrd Franz, Georg Dietz, Vice President of First Business Unit, Matthias Fix, Vice President of Commercial Vehicle Sales, Hu Kun, President of China, and Xu Huanping, Vice President of Sales, China attended the launch ceremony and witnessed This new product release event.

At the press conference, the Xichai Aowei 6DM3 first equipped with MAHLE laser-welded steel piston products achieved five major improvements through five “further”:

Further increase power and torque to 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.

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 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;

Further reduce the height of the cylinder and increase 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;

Further extend the mileage of oil replacement and improve the economy 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;

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.

The cooperation between FAW Jiefang Engine Division 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.

The world's most advanced laser-welded steel piston products have achieved the first match on the Xichai Aowei 6DM3, marking a new era of cooperation between the two parties, a milestone. This cooperation is a favorable exploration for the two sides to deepen strategic cooperation. In the future, the two parties will apply this cooperation experience to more leading technology cooperation to jointly create "China's leading, internationally renowned" engine products and brands.
