Exploring the lightweight design of Dulwich engines

With China's increasingly strict control on vehicle exhaust emissions and the ever-evolving emission standards of automobiles, many manufacturers have begun to develop engines that meet the new standards. In order to cope with this trend, Yunnei Int'l has successively launched the National Five and National Six products in recent years. Among them, the Dulwich Fine Art Project has attracted attention and has made breakthroughs in lightening, appearance optimization and quality improvement. This is not something that is blown. Both facts and figures prove that they do not believe. Then look down.

In terms of lightweight design, Yunnei Dynamics started with parts and components, and improved the materials of the DKW engine gearbox, flywheel housing, and bracket components. The original cast iron parts were changed to cast aluminum parts, which greatly reduced the number of engines. The weight, while the signal plate and other castings were changed into spinning parts, further reducing the weight of the engine. Through the above-mentioned "downsizing" means, the entire Dulwich series models have an average weight reduction of 20KG or more.

Many people are worried that lightweight design will not affect the performance and reliability of the engine. The engineers of Dwe Motors have also taken this into consideration. Therefore, in the early stage of lightweight treatment, the feasibility and strictness of the feasibility assessment are assessed. At the same time, During the lightweight design process, CAE calculations and analysis are required for every minor change to ensure that the lightweight engine performance is still excellent.

However, scientific calculation can not stand the test of practice? This is a problem.

As we all know, there are three ways to test the reliability of the engine, namely the bench test, the road validation of the vehicle and the “three-high” calibration experiment. These three tests can directly verify the reliability of the optimized engine. After these tests, Dulwich Engine made a happy conclusion: Compared with the optimization, the optimized Dulwich engine is still very full of power, while the fuel consumption is reduced by about 3%.
