The secret to the success of China's internal combustion engine industry in the past decade lies in the triple synergy of technological breakthroughs, precise policy guidance, and energy path innovation. Represented by Weichai Power, the company continues to break global thermal efficiency records - by 2024, the thermal efficiency of diesel engines will reach 53.09%, and that of natural gas engines will exceed 55.9%, establishing China's global leading position in the field of high-efficiency power. The National VI B emission standards have forced the widespread adoption of technologies such as direct injection, EGR, and GPF, driving engines from meeting standards to a new stage of high performance and low consumption. The 'Energy saving and New Energy Vehicle Technology Roadmap 3.0' specifies that by 2040, hybrid vehicles with internal combustion engines (HEV/PHEV) will still account for one-third of passenger car sales, establishing their irreplaceability as the 'low-carbon transition core'. On the zero carbon path, the Yuchai YCK16H hydrogen internal combustion engine achieves zero carbon emissions in the commercial vehicle field, with 90% of its components reusable on traditional production lines and significant cost advantages, becoming a key pivot for heavy machinery to 'overtake on changing lanes'. Top enterprises have built a full stack capability of 'engine hybrid system intelligent control', with a replacement rate of over 80% for domestic ECU and electronic control systems, promoting the transition of products from 'scale export' to 'technology output'. Internal combustion engines are transitioning from being replaced to being a key component of carbon neutrality systems.
