On the morning of January 8, Weichai released the world's first ontology thermal efficiency 51.09% diesel engine and major hydrogen energy technology demonstration results in Jinan.
As a leading enterprise in the equipment manufacturing industry, Weichai launched the "double engine" strategy, walking on two legs of traditional power and new energy industry, achieving a historic breakthrough in both, and driving Weichai to lead the world.
Traditional power continues to set new records and lead the world
"If Chinese automobiles want to achieve the great goal of changing from big to strong, they must do a good job in transformation and upgrading, upgrading in transformation and transforming in upgrading." In the view of Fu Yuwu, chairman of the Society of Automotive Engineers of China, in order to achieve the transformation of the automobile industry from big to strong, it should achieve the synchronous promotion of traditional power upgrading and new energy technology innovation.
In fact, thermal efficiency and exhaust emissions are a pair of "contradictions", the higher the former, the more difficult it is to meet the standards of the latter. Since 1876, when the German Otto invented the reciprocating piston four-stroke gasoline engine on the basis of the atmospheric pressure engine, the automobile internal combustion engine has been looking for a balance between efficiency, energy saving and environmental protection for more than a hundred years.
On September 16, 2020, Weichai released the world's first commercial diesel engine with a thermal efficiency of 50.23% in Jinan, which caused a sensation in the industry. Many industry experts have likened this to the first 100-meter run in human history, and some have even asserted that the record will dominate the entire internal combustion engine industry for many years. However, after 480 days, Weichai people challenged themselves, breaking this record, pushing the thermal efficiency of the diesel engine body to 51.09% for the first time in the world.
Thermal efficiency is a measure of the fuel utilization efficiency of internal combustion engines, is a symbol of the comprehensive strength of a country's diesel engine technology, the higher the thermal efficiency, the less fuel consumption, the more significant the effect of energy saving and emission reduction. This technological breakthrough is of great strategic significance for promoting energy conservation and emission reduction and green development of China's traditional internal combustion engine industry, and has an important technological leading role in the global internal combustion engine industry.
The International Federation of Automotive Engineers sent a congratulatory letter to Weichai: this is an important milestone in the history of scientific and technological progress in the automotive engine industry, and will also make a significant contribution to the sustainable development of the global industry and energy conservation and emission reduction.
Hydrogen energy industry layout in advance multi-point flowering
While promoting breakthroughs in traditional power technologies and low-carbon upgrading, Weichai regards the development of new energy industries as one of its important strategic directions.
Industrial change, technological innovation first. Not long ago, the National Energy Administration released seven key projects for energy work in 2022, accelerating the promotion of technical equipment research and focusing on key areas such as hydrogen energy.
The leading Weichai is always one step ahead. On January 8, at the National Fuel Cell Technology Innovation Center and the "Hydrogen into Ten Thousand Homes" Project Operation Symposium, Weichai demonstrated a series of pioneering achievements in the hydrogen energy industry.
The industry's first 200kW class vehicle fuel cell engine products, unveiled at the national "13th Five-Year Plan" scientific and technological innovation achievement exhibition; the first high-power containerized hydrogen fuel cell combined heat and power system, the first high-power solid-state oxide fuel cell cogeneration system put into operation; China's first intelligent hydrogen fuel cell snow wax vehicle with completely independent intellectual property rights, serving the Beijing Winter Olympics; the country's first "hydrogen + 5G" smart green port, the country's first "car-station-road" linkage hydrogen energy high-speed, The country's first hydrogen energy low-carbon industrial park... Weichai has achieved multi-point flowering in the promotion and application of hydrogen energy.
The results come from an early layout. In 2008, Weichai comprehensively laid out the new energy business, invested a total of 5 billion yuan, gathered nearly 1,000 R&D teams to carry out key new energy technology research, injected strong impetus into the development of Shandong's hydrogen energy industry, and led new changes in the global power field.
Under the guidance of the national 'double carbon' strategy, hydrogen energy, as a clean energy source, will play a key role in china's road to achieving carbon neutrality." A battle to use hydrogen energy as a fulcrum and aim at the "double carbon target" has begun.
"Weichai will achieve 'double engine' drive, unswervingly realize the traditional high-end power and new energy power to take the lead, in the scientific and technological revolution and industrial change, for the national 'double carbon' strategy to open up a new path for diversified energy transformation." Tan Xuguang, secretary of the party committee and chairman of Shandong Heavy Industry Group, chairman of Weichai Power and director of the academic committee of the National Fuel Cell Technology Innovation Center, said.
