two thousand and twenty-fiveInternal combustion engine exhibits four major wind phenomena

At this exhibition, the exhibited products are moving towards diversified technological routes, scenario based, high-efficiency, and electric driven system development.

Firstly, manufacturers are no longer limited to traditional diesel engines, but are all using natural gas, methanol, hydrogen fuel, hybrid power, and pure electric driveComprehensive layout has been carried out in various fields. Especially hydrogen and hybrid have become the focus of competition. Secondly, it is scenario based deep customization, which shows that each product development is closely tailored to specific application scenarios, providing "customized" solutions.

Although new energy has become a trend at this exhibition, traditional power still has a place, such as "National VI", "thermal efficiency", and "low gas consumption"/Fuel consumption "and" zero emissions "have become keywords. All enterprises are committed to achieving higher energy efficiency and lower emissions through advanced technology.

Not only the engine, but also at the core component level, the electric drive bridge emphasizes integration, high efficiency, and low maintenance, and has been exhibited by many companies in this year.

In addition to hardware parameters,B10Lifespan, long oil change cycle, intelligence, and full lifecycle cost/Profitability has become a new competitive advantage emphasized by manufacturers, indicating that industry competition is extending from product performance to comprehensive solutions and reliability.
