51% Thermal Efficiency + Fuel Cell Weichai Power Starts New and Old Energy "Twin Engines"

Shanghai Securities News China Securities Network News A few days ago, the release of two major products of Weichai Power has aroused the attention of the industry and the capital market. In the field of traditional energy, the first ontology thermal efficiency 51.09% diesel engine was released, which was the first diesel engine with a thermal efficiency of 50.23% in September 2020, which once again refreshed the thermal efficiency limit of the diesel engine; in the direction of hydrogen energy, Sinotruk Heavy Duty Tractor supporting Weichai's independent development of hydrogen fuel cell system completed the first delivery to Shandong Port Group. As a result, Weichai Power has crossed the two tracks of new energy and high-end power and entered the "dual engine" development model.

The internal combustion engine still has a wide market demand in the long future period of time, and it is also the field with the greatest potential for energy conservation and emission reduction. Deep ploughing in the diesel engine industry for 75 years, Weichai Power has invested tens of billions of yuan in research and development in recent years, achieving today's leading position - "moat" continues to expand, "ballast stone" continues to build, and scientific and technological attributes are gradually highlighted.

The thermal efficiency of Weichai power diesel engine body reached 51.09%, which is another major revolution in the thermal efficiency of traditional power, and also provides technical preparation for the implementation of the "National SEVEN" emission standards. The application of this technology is expected to bring Weichai Power a competitive advantage and help its internal combustion engine market share continue to break through.

While promoting energy conservation and emission reduction in the traditional internal combustion engine industry, green and low-carbon hydrogen fuel cells are also the direction of Weichai Power Technology Team to overcome difficulties. Since the "Hydrogen into Ten Thousand Homes" science and technology demonstration project landed in Shandong, Weichai Power has relied on the National Fuel Cell Technology Innovation Center to carry out technical research and industrial demonstration and achieved fruitful results: the industry's first environmental adaptability test of fuel cell fleet under extremely cold conditions has been carried out, and the industry has achieved a product life of 30,000 hours. Create leading performance products, strong power, green environmental protection, safe and reliable, efficient and full attendance. Continuously expanding new scenarios, the first high-power containerized hydrogen fuel cell cogeneration system and the first 30kW solid-state oxide fuel cell cogeneration system in China were put into operation in Weifang; the country's first port hydrogen fuel cell heavy truck demonstration operation project was launched in Qingdao Port; and the 49-ton fuel cell heavy truck supporting Weichai Power Products ran for more than 5,000 kilometers on the route from Jinan Taigang to Qingdao Dongjiakou Port Area. The exploration and application of hydrogen energy parks, hydrogen energy ports and hydrogen energy high-speed have injected new momentum into Weichai's high-quality development.

It can be seen that whether it is the energy saving and emission reduction brought about by the improvement of the thermal efficiency of the internal combustion engine or the environmental protection and low carbon of hydrogen energy, Weichai Power is actively forging ahead. (Zhu Jianping)
