November 20，The world's first body thermal efficiency developed by Weichai Power 52.28%Commercial diesel engine and the world's first bulk thermal efficiency 54.16%Commercial Natural Gas Engine Shocking Release，Several authoritative research institutes、Industry organizations and media representatives witnessed the historic leap of commercialized internal combustion engine technology.。

Sinotruk and Weichai Power belong to Shandong Heavy Industry Group.，As a colleague of the group's collaborative research and development，Sinotruk will be the first in the world to carry Weichai Thermal Efficiency 52.28%Diesel and 54.16%Natural gas engine commercial vehicle enterprise，Once again in the commercial vehicle industry successful interpretation“1+1>2”The pattern of great synergy.。

China's acceleration on the road of internal combustion engine research and development

1897，The world's first diesel engine was born in Germany，China's first fully self-produced diesel engine did not come out until 1932.，For quite a long time.，China has always been an imitator and pursuer in the field of diesel engines.。After decades of hard work and innovation，China's diesel engine technology has finally entered the fast lane.，Accumulate strong R & D strength，And finally, 125 years later,，It has become the leader of many core technologies in the field of global diesel engine.。

Weichai Power in September 2020、January 2022、In November 2022, the thermal efficiency of the body was released as 50..23%、51.09%、52.28%A diesel engine，Each time, it breaks through the highest bulk thermal efficiency of commercial diesel engines in the world.，Three years“Triple jump”，The breakthrough of high efficiency power ceiling has been achieved three times in a row.。

Bulk thermal efficiency 52.28%Commercial Diesel and Bulk Thermal Efficiency 54.16%Launch of a commercial natural gas engine，It is the third time in three years that Weichai Power has refreshed the global record in this technology field.。Every breakthrough of the limit，It is inseparable from the efforts of the R & D team.、Li Fen Fa。This breakthrough in thermal efficiency，Weichai R & D team overcomes technical problems one by one，Realize 162 patents for diesel engine，124 authorized patents，165 patents for natural gas engine，135 authorized patents。The most breakthrough in the thermal efficiency of diesel engine and gas engine.，It marks that the research and development of internal combustion engines in China has entered the international advanced level.，At the same time“Double Carbon”Society in a Strategic Context、Requirements for economic development，It highlights the mission and responsibility of national brands.。

Leading by Science and Technology Enabling Economic Value

The bulk thermal efficiency of an engine represents the proportion of fuel energy converted into effective work output.，That is, how much of each drop of oil can be converted into the power of the vehicle after combustion.。Body thermal efficiency before Weichai 51.09%Diesel engine，8% more fuel-efficient than the industry average%，The release of the world's first thermal efficiency 52.28%Diesel engine，Make another breakthrough in fuel saving，12% less fuel than the industry average%，Fuel-saving performance further improved 4%，Have higher economy。From the level of high-value operation of Enabling Card Friends，This is the significance of the breakthrough in the thermal efficiency of the engine body.。

In recent years，As a subsidiary of Shandong Heavy Industry Group,，Sinotruk and Weichai Power always carry out collaborative research and development、Resource sharing，Weichai engine has achieved the optimal matching with the whole vehicle products of China Heavy Truck.。Weichai engine+The Seventh Generation Self-developed by SinotrukS-AMT16 Transmission+Man Technology Axle Composed InfinitySPower chain，Easy integration and perfect matching。Weichai high thermal efficiency diesel engine can save fuel 12%，Transmission efficiency over 99.8%The seventh generationS-AMT16Gearbox saves fuel 3%，The only man technology axle with oil filter in China saves 0..5%，The comprehensive transmission efficiency of the whole vehicle can be up to 93%，The new generation of high thermal efficiency diesel engines makes the infiniteSComprehensive fuel saving of power chain reaches 15.5%，It greatly improves the revenue of vehicle operation.，Let Scientific and Technological Innovation Benefit Card Friends。

Today, independent brands can more and more represent the economic strength of the country.，Technological innovation has become an important means of enterprise evergreen.。Only by constantly realizing technological innovation，In order to better meet the needs of the market and customers.。Sinotruk and Weichai Power through continuous collaborative research and development，Set a new benchmark for global internal combustion engines and commercial vehicles，Deduced the commercial vehicle industry“1+1>2”A miracle，Further boost the dream of automobile power，Let more Chinese intelligent manufacturing step onto the world stage.。
