Compared with other fuels, using diesel plus ammonia requires less modification to the original engine. While meeting the power performance of the original engine, its economy and emissions can be greatly improved. It has less pollution to the atmosphere and is a clean alternative fuel for vehicle engines.

[0003] In summary, a diesel-ammonia dual-fuel engine supply device is proposed to solve the aforementioned problems. Utility Model Content
