On September 24, 2024, the 21st China-ASEAN Expo (CAEXPO) opened in Nanning, Guangxi, with great fanfare. The event was attended by key dignitaries, including Ding Xuexiang, Member of the Standing Committee of the Political Bureau of the CPC Central Committee and Vice Premier of the State Council, who delivered the opening speech. Yuchai, one of China’s leading power equipment manufacturers, showcased its groundbreaking innovations, including the world’s first hybrid electric drive continuously variable transmission (CVT) powertrain and China’s most powerful hydrogen engine. These innovations were reviewed by national leaders, further cementing Yuchai’s status as a leader in low-carbon and intelligent power technologies.

This year’s expo, themed “Amity, Sincerity, Mutual Benefit, and Inclusiveness for Common Development—Promoting the Construction of China-ASEAN Free Trade Area 3.0 and Regional High-Quality Growth,” highlighted the evolving cooperation between China and ASEAN nations. Yuchai took center stage at both the “New Era, Magnificent Guangxi” exhibition and the Advanced Technology Exhibition, where it emphasized its cutting-edge advancements in low-carbon intelligent power.

Yuchai’s Technological Highlights A major attraction at Yuchai’s booth was the globally pioneering IE-POWER hybrid electric-drive continuously variable powertrain, which has revolutionized heavy-duty tractors. The tractor equipped with IE-POWER offers significant efficiency improvements, boasting a 35% increase in plowing and rotary tillage efficiency while reducing fuel consumption by up to 30%. This innovation also delivers reduced noise, enhanced comfort, and supports unmanned operation, making it a breakthrough in China’s large-scale agricultural machinery and its entry into the new energy sector.

Yuchai also highlighted other significant technological achievements, such as:

• K05H Hydrogen Engine: China’s first commercial vehicle hydrogen engine, symbolizing the company’s commitment to zero-emission power solutions.
• K15H Hydrogen Engine: The largest displacement and highest horsepower hydrogen engine in China, setting new standards for power and performance in hydrogen-fueled engines.
• Flexible Fuel Engine Platform: China’s first engine platform capable of commercial operation using flexible fuels, offering versatile and sustainable power solutions.
• Fuel Cell System: A fuel cell system that leads the country in durability and safety, demonstrating Yuchai’s leadership in hydrogen and fuel cell technologies.
• YC6TD Gas Generator Set: A more economical and efficient gas generator set, providing advanced power solutions for various industries.
• 50kW Silent Generator Set: Designed for quiet operation, this generator set offers a balance of power and noise reduction, making it ideal for sensitive environments.
• YCF11 Diesel Engine: With superior power, torque, and fuel efficiency compared to international competitors, the YCF11 diesel engine is set to raise the bar for industrial engines.
• YCD4A33C6 Marine Engine: Leading in power-to-weight ratio, this marine engine is optimized for performance and efficiency, solidifying Yuchai’s position in the marine power industry.

A Major Event for Innovation and Global Cooperation The 21st CAEXPO, covering nearly 200,000 square meters, brought together over 2,000 enterprises. For the first time, international organizations such as the Secretariat of the Shanghai Cooperation Organization (SCO) and the United Nations Industrial Development Organization (UNIDO) participated. Additionally, exhibitors from countries such as Japan and South Korea continued their involvement, underscoring the event’s importance as a global platform for fostering technological and economic collaboration.

Yuchai’s impressive showcase of low-carbon, intelligent power solutions at CAEXPO 2024 highlights its commitment to sustainable development and its ambition to lead the future of clean energy technologies. Through innovations in hydrogen engines, hybrid powertrains, and fuel cell systems, Yuchai is poised to play a pivotal role in the green transformation of industries both domestically and internationally.
