The 2024 Germany Hannover International Transportation Expo (IAA TRANSPORTATION 2024) was recently launched, and on this high-energy stage of global commercial vehicle industry exchanges, the cutting-edge technologies and cutting-edge products of the global commercial vehicle industry development have become the focus of public attention.
As the world's top power equipment company, Weichai has brought a lot of "top goods", including 53% high-thermal efficiency diesel engines that meet Euro VII emission standards, WP14T hybrid powertrains, WP15 flexible fuel internal combustion engine platforms, 300kW hydrogen fuel cell power systems and other cutting-edge products covering multiple technology routes.
From these products, it can be clearly seen that Weichai's strategy of going overseas is gradually transitioning from "product going overseas" relying on cost advantages to "technology going overseas" relying on technological advantages, which fully demonstrates the competitiveness of "Made in China".
For a long time, well-known European and American enterprises have invested a lot of R&D resources and have never exceeded 50% of the thermal efficiency of the diesel engine body. At the same time, on the road to emission upgrading, whether for foreign engine manufacturers or domestic engine manufacturers, the Euro VII or China VII emission standards can be said to be the limit of internal combustion engines.
For Weichai, the "limit" is meant to be broken.
Since 2015, with the support of the National Key R&D Program, Weichai Chain has taken the lead in breaking through the thermal efficiency of 50% of the diesel engine body with the strongest brains and industry-university-research partners at home and abroad, and has refreshed the diesel engine body thermal efficiency record held by itself for four consecutive times, demonstrating Weichai's hard core strength to the world.
The 53% high thermal efficiency diesel engine exhibited by Weichai to meet the Euro VII emission standard is the Euro VII diesel engine with the highest thermal efficiency of diesel engine in the world, which has a variety of hard-core black technology, economic and energy-saving, and the generalization rate of parts is > 97%, and the engine has been fully verified by the market, with a B10 life of up to 1.8 million kilometers.
According to Weichai's official statistics, in the past 10 years, Weichai has invested a total of 30 billion yuan in scientific and technological research and development, which has not only achieved the global leadership from the traditional powertrain, but also completed the comprehensive layout of new energy, from the low-end "involution" of the value chain to the global high-end market breakthrough.
At the 2024 IAA booth, Weichai not only demonstrated its leading technological advantages in traditional power, but also showed its outstanding achievements in the field of new energy technology.
Weichai WP14T hybrid assembly, double planetary structure, multi-power coupling output, cancel clutch, shift power without interruption; The dual-motor brake recovery efficiency is higher, and the fuel saving is 25% under the legal working conditions; Under different speeds and driving scenarios, the working mode can be intelligently switched to ensure power and economy.
WP15 flexible fuel internal combustion engine platform, based on advanced design concept, through a small number of parts and software control, to achieve a multi-fuel direct injection solution; Through the combination of multiple groups of sensors monitoring strategy, the reliable monitoring of combustion, exhaust and crankcase is realized; In the context of carbon reduction and carbon reduction, emissions are fully in line with the EU zero carbon standard.
The 300kW hydrogen fuel cell power system is mainly used in the medium and long-distance transportation of high-speed trunk lines of heavy-duty tractors; High-precision active and passive hydrogen cycle wide-range flow supply technology, with the highest efficiency of more than 63%; Intelligent control and online health management, strict and comprehensive reliability verification, service life of more than 30,000 hours; Stack low-temperature self-generated heat, dynamic water heat management, intelligent purge strategy and other technologies, cold start temperature ≤-35°C.
It can be said that Weichai's technological innovation and breakthroughs in many fields have once again amazed the world. Through the international window of IAA, Weichai not only shared more of China's manufacturing achievements with the world, but also demonstrated the strong strength and great potential of China's automobile industry. These world-leading technologies have not only promoted the rapid development of China's automotive industry, but also made important contributions to the progress of global automobile manufacturing technology.
