Southwest Research Institute(Southwest Research Institute,SWRI )Join hands with Cummins and industry-leading suppliers,Jointly promote the development of hydrogen internal combustion engine technology to reduce emissions。At present,The projectVehicle equipped with hydrogen internal combustion engine,Has been put into fleet application demonstration,Learn from the actual operation experience of the fleet。
Early this year
SWRIA major breakthrough was announced.
Its modified hydrogen internal combustion engine almost completely eliminates nitrogen oxides in the exhaust gas.(NOx),Emissions are significantly reduced,Only0.008g/hp-hr,This value is much lower than EPA.EPA 2027 Emission Standard,Less than 1% of standard limit/4,And lower than California Air Resources Board.(CARB)Ultra-lowNOxEmission standards。AtFTPIn the driving cycle test,Compared to diesel engines,Carbon dioxide emissionsDecrease 99.7%,And that great potential for reduce the emission of the hydrogen internal combustion engine is shown.。
As the Hydrogen Internal Combustion Engine Alliance(H2-ICE Consortium)An important participant,Cummins toSWRIProvided its multi-fuel platform(HELM™)A flagship product——X15NNatural gas engine,SWRIConvert this engine to a hydrogen-powered engine。
We are very happy to be involved in this project.。In this project,Each partner has its own unique expertise and resources,To contribute to the development of hydrogen internal combustion engine technology。

Other members of the alliance include Bosch.、Phinia、Super Turbo MAHLE、SEMEtc。The modified hydrogen internal combustion engine was installed in aInternational LTOn the Truck,Provide power for it。
The core task of the first phase of the Hydrogen Internal Combustion Engine Alliance is to build Vehicles equipped with hydrogen internal combustion engines and collect their main emission data.。In the next phase,SWRIAnd its members will pay more attention to Vehicle performance.、Traction and shift performance。

The test engine will be launched with Cummins.X15HDifferent。The purpose of this modification is to show you,Leverage existing engine architecture,Can quickly and conveniently realize hydrogen power conversion。From rebuilding the engine,To be fitted to Class 8 long-haul Trucks and achieve the desired emissions results,Only took 18 months.。
ByX15NHydrogen internal combustion engine modified from natural gas engine,Most of the original engine components are used.,About 90%The engine components can be used in common.。
In the first phase,SWRIUse of a 30 kg hydrogen storage system provided by another member of the Alliance,The vehicle has a maximum driving range of 300 miles.。The agency said,Larger capacity systems can be installed on demand in the second round of upgrade,Achieve 600 to 700 miles of endurance。
Cummins plans to launch the 700 in 2024 bar IVHydrogen storage tank(AH620-70),Lightweight for North American Heavy Duty Trucks、Economical solution。
