After being awarded the title of "National Excellent Engineer", Tan Xuguang, Secretary of the Party Committee and Chairman of Shandong Heavy Industry Group Co., Ltd., Chairman of Weichai Holding Group Co., Ltd. (hereinafter referred to as "Weichai"), and Director of the National Key Laboratory of Internal Combustion Engine and Power Systems, tirelessly devoted himself to his busy work. He organized the 2024 Group Science and Technology Innovation Award Conference and proposed to vigorously promote the spirit of engineers; Special commentary on the business of subsidiaries worldwide, and forward-looking layout; Researching various business sectors in China, and then improving innovation and services... Focusing, investing, and being busy is his norm, and it is also his interpretation of the connotation of "National Excellent Engineer" through practical actions. "The honor of 'National Excellent Engineer' is a recognition of my past work." Recently, in an interview with a reporter from Science and Technology Daily, Tan Xuguang said, "In the position of engineer, I will continue to work hard; not only will I do well myself, but I will also lead the next generation of engineers to calm down, calm down, and achieve success." A product, a company, has been working in Weichai for a lifetime. Tan Xuguang started working in diesel engine testing and became the "leader" of the enterprise at the age of 37, step by step. So far, he has been engaged in internal combustion engine and power system technology innovation and engineering management work for over 47 years. He was devoted to scientific research and led a team to increase the thermal efficiency of diesel engines from 38% in the 1990s to 50.23%, 51.09%, and 52.28%, setting world records three times in a row. He was praised by the international authoritative testing agency, Germany's South German Group, as "at the most advanced level in the global engine industry", giving peers around the world a thumbs up. He won the first prize of the National Science and Technology Progress Award as the first adult and won 15 provincial-level and above science and technology awards. As a technology-based entrepreneur, he implanted technological innovation into the DNA of Weichai, reviving a company on the brink of bankruptcy and creating a revenue of 310 billion yuan, becoming a benchmark for state-owned enterprise reform and a model of focusing on its main business. "One product, one enterprise, worked for a lifetime." This sentence accurately summarizes Tan Xuguang's career and pursuit. The engine is the "heart" of a car. Starting from the introduction, digestion, absorption, and improvement of the Steyr engine, Tan Xuguang set a lofty goal for himself and his colleagues - "Can we become a world-class engine company?" The ideal is lofty, and challenges are always present. From the initial mechanical transmission to the trendy electronic control, and now to the new energy, the "question of the route" in the evolution of new technologies tests the judgment of decision-makers. Tan Xuguang is well aware that many multinational companies are struggling due to technical judgment errors. During the interview, the reporter heard a story. 2014 is known as the first year of new energy vehicles, and new energy vehicles experienced explosive growth. Tan Xuguang had a keen intuition and said, "New energy is coming.". In one year, he flew over 400000 kilometers around the world, to Silicon Valley, Stanford University, and various innovative companies in Europe and America that specialize in intelligent driving... He firmly believed that "without investigation and research, there is no right to speak, let alone decision-making power.". Afterwards, Weichai took the lead in building the National Fuel Cell Technology Innovation Center and comprehensively laid out power electricity
