4 World Data Set Weichai Energy Unveils World’s First Diesel Engine with 53.09% Thermal Effectivity
TIANJIN, China, April 20, 2024 /PRNewswire/ — On April 20, 2024, the 2024 World Congress on Inside Combustion Engines grandly commenced in Tianjin, China, showcasing the {industry}’s newest technological developments. On the occasion, Weichai Energy unveiled the world’s first diesel engine with an intrinsic thermal effectivity of 53.09%. This exceptional achievement was formally acknowledged by TÜV SÜD, a world authoritative testing group, and the China Automotive Know-how & Analysis Middle, knowledgeable testing physique for Chinese language inner combustion engines. Each organizations issued product testing experiences and certificates to Weichai Energy, confirming the corporate’s new world document in the important thing financial index of diesel engine thermal effectivity.
For the reason that inception of diesel engine 127 years in the past, scientists and engineers internationally have pursued the aim of enhancing thermal effectivity as a lifelong endeavor. This intricate problem not solely encompasses a fancy system engineering course of but additionally represents a measure of a nation’s complete energy in inner combustion engine expertise. Over time, the continual quest to enhance the thermal effectivity of diesel engines has remained an ongoing worldwide problem.
Since 2015, Weichai Energy has assembled a high-thermal effectivity engine analysis group comprising tons of of younger Ph.D. holders and 1000’s of engineers. This group has been collaborating with main minds domestically and internationally, together with industry-university-research companions, to conduct cutting-edge technical analysis and frequently push the boundaries of innovation. On September 16, 2020, Weichai Energy marked a big milestone by introducing a diesel engine with a record-breaking physique thermal effectivity of fifty.23%. The corporate continued its exceptional progress by additional growing the engine’s thermal effectivity to 51.09% on January 8, 2022. Most not too long ago, on November 20, 2022, the corporate surpassed its earlier achievements, reaching a formidable 52.28% thermal effectivity, which demonstrates Weichai Energy’s pivotal position in main the worldwide inner combustion engine {industry}’s technological development.
Constructing on its earlier achievements, Weichai Energy’s analysis group devoted greater than 500 days of targeted effort to additional refine 4 essential techniques: combustion, air consumption, gasoline supply, and friction discount. The group efficiently superior high-expansion combustion, mixed-flow pressurization, high-efficiency gasoline injection, and low-resistance friction-reducing applied sciences. These developments, achieved by way of incremental good points of 0.1% at every step, culminated in a exceptional milestone: breaking by way of the 53% thermal effectivity barrier for the primary time globally, a feat akin to a human operating the 100-meter race below 9 seconds. Throughout this analysis and growth course of, the group was granted 176 invention patents and 68 utility mannequin patents.
Mr. Dirk von Wahl, CEO of TüV SÜD North Asia, prolonged his congratulations to Weichai by way of video message. He acknowledged that Weichai’s current achievements are distinctive on the worldwide stage, far exceeding present requirements. This displays not solely Weichai’s strong scientific analysis capabilities but additionally its sturdy technical prowess within the inner combustion engine {industry}. Wahl expressed his perception that this technological milestone will considerably assist China’s carbon peaking and carbon neutrality targets and inexperienced growth initiatives, whereas additionally contributing to the sustainable development, power conservation, and emissions discount of industries worldwide.
Based mostly on present estimates of Chinese language diesel engine possession, upgrading from a thermal effectivity degree of 45-46% to 53% can enhance the diesel engine economic system by roughly 14%. This development interprets to annual gasoline financial savings of round 31 million tons and a discount in carbon emissions of roughly 97 million tons. For a heavy-duty tractor that travels 250,000 kilometers yearly, this enchancment can save roughly 12,000 liters of diesel gasoline every year. Given the present market value of diesel gasoline at 7.8 yuan per liter, this equates to an annual financial savings of about 98,000 yuan for the proprietor. Along with transportation, this technological development will lengthen its influence to varied sectors, together with development equipment, agricultural tools, ships, and energy technology tools, making new contributions to the world’s financial and social growth.
Tan Xuguang, vice chairman of the Chinese language Society for Inside Combustion Engines, director of the State Key Lab of Engine and Powertrain System, and chairman of Weichai Energy, and Chairman of Weichai Energy, attributed Weichai Energy’s 4 consecutive breakthroughs in diesel engine thermal effectivity to the almost 4,000 days and nights of mental dedication by Weichai engineers. He additionally acknowledged the essential position of open collaboration with high international universities and analysis establishments, in addition to the synergy achieved by way of innovation with the worldwide industrial and provide chains. Tan emphasised that this achievement not solely belongs to Weichai but additionally contributes to the development of the worldwide {industry} as an entire.
