BERLIN, Sept. 16 (Xinhua) -- German engineering and technology company Bosch and Chinese engine manufacturer Weichai Power increased the efficiency of Weichai diesel engines for heavy commercial vehicles from 46 percent to 50 percent, Bosch announced on Wednesday.

"In increasing the efficiency by four percentage points, we have jointly reached a new milestone. Even though the diesel engine is nearly 130 years old, its development continues," said Volkmar Denner, chairman of the board of management of Bosch.

The six-cylinder diesel engine by Weichai with a 12.9-liter displacement was equipped with Bosch's modular common rail system for commercial vehicles.

"Bosch offered great support on the breakthrough and unprecedented achievement of 50 percent efficiency in Weichai commercial-vehicle diesel engine. We are very pleased to be continuing our highly successful partnership with Bosch," said Tan Xuguang, chairman of the Weichai Group.

According to Bosch, the system could be used in different engine sizes with up to eight cylinders. Depending on the level of utilization, a lifetime of up to 1.6 million kilometers could be achieved, according to the German company.

The "strategic alliance" between Bosch and Weichai dates back to 2003. According to Bosch, the diesel engine project was started in September 2018 and achieved its goal after only two years of development.

"This common achievement does not only show the further potential of modern Diesel technology for efficient commercial mobility. It is also a great example for the long-standing and successful cooperation between Bosch and Weichai," a Bosch spokesperson told Xinhua on Wednesday.

 

柏林,9月16日(新华社)——德国工程技术公司博世和中国发动机制造商潍柴动力周三宣布,将重型商用车潍柴柴油发动机的效率从46%提高到50%。


他说:“效率提高了4个百分点,我们共同达到了一个新的里程碑。尽管柴油发动机已经使用了近130年,但它的发展仍在继续,”博世管理委员会主席Volkmar Denner表示。


潍柴的六缸柴油发动机排气量为12.9升,配备了博世用于商用车的模块化共轨系统。


“潍柴商用车柴油机实现50%效率的突破和前所未有的成就,博世给予了极大的支持。”我们很高兴能继续与博世保持高度成功的合作关系,”潍柴集团董事长谭旭光表示。


据博世介绍,该系统可用于多达8个气缸的不同发动机尺寸。据这家德国公司说,根据使用水平,最长可达到160万公里的使用寿命。


博世与潍柴的“战略联盟”始于2003年。据博世介绍,该柴油发动机项目于2018年9月启动,仅经过两年的开发就实现了目标。


“这一共同的成就不仅显示了现代柴油技术在高效商业交通方面的进一步潜力。”这也是博世和潍柴长期成功合作的一个很好的例子。”博世发言人周三告诉新华社。
