November eleventh，When everyone is immersed in the shopping craze of double eleven discount，A conference that attracted the attention of construction robots was held in Changsha, Hunan Province.。Liebherr with the right.“0”The commitment of emissions entered the 2022 China International Internal Combustion Engine and Power Equipment Expo.。

Engine China

 

At this conference，Liebherr not only offers highly efficient injection solutions for diesel fuel，Direct injection solutions using hydrogen as fuel were also exhibited for the first time.。Liebherr believes that the internal combustion engine of the future will not be powered by fossil fuels.，But from renewable energy or sustainable clean energy.——Hydrogen。

 

 

Exhibit 1

 

 

[ The heart of the hydrogen internal combustion engine ]

Hydrogen injection system

In the highway and non-highway areaOEMAnd engine manufacturers are increasingly interested in hydrogen as a fuel.。Liebherr as development partner and system supplier for climate-friendly jet technology，Are provide solutions for hydrogen internal combustion engine that can be used in both on-road and off-road applications。

 

The high-pressure hydrogen comes out of the hydrogen storage tank.，

Regulate the hydrogen pressure to a working low pressure through the pressure regulating valve。

Hydrogen at low pressure is charged into the hydrogen rail，

According to the firing order of the engine，

The hydrogen in the gas track is in the correct order by the hydrogen injection valve

Into the appropriate engine cylinder。

The hydrogen is then ignited by a spark plug to convert it into power。

 

For a hydrogen internal combustion engine，Hydrogen direct injection system is the core of the research and development.。The aim of the hydrogen injection technology is to ensure that the gas injection system (GIS) Applicability to meet engine transient requirements。This system-oriented approach combines various components to control pressure and flow，This makes the performance of hydrogen direct injection system close to that of diesel engine.，While maintaining a robust and reliable system design。

[ Hydrogen fuel cell is a powerful pusher ]

New type“Double stage”Compressor 25KW

With the rise of environmental awareness，Green travel、Reducing carbon emissions has become the most important livelihood plan that needs attention at present.。In addition to the well-known pure electric vehicles on the market,，There is such a technology，It is environment-friendly and energy-saving、The dynamic efficiency is equal to the former.，Even some indicators performed well.，R & D and design are fully supported in many countries，That is hydrogen fuel cell technology.。

 

Electric air compressor is the core component of fuel cell system.。If the fuel cell system is compared to the human body,，A stack can be compared to a fuel cell.“Heart”，Then the air compressor can be called a fuel cell.“Lung”。The same，The high performance output of the fuel cell system requires this powerful“Cardiopulmonary function”*。

The air compressor is responsible for delivering clean air with specific pressure and flow rate to the stack in the fuel cell system.，Provide the necessary oxygen for the stack reaction，Make the stack produce more chemical reactions to produce more electricity.。To make the fuel cell system powerful,“Cardiopulmonary function”，What are the characteristics of the air compressor?？
