Combustion, performance and emission characteristics of CI engine fueled with diesel and hydrogen based reactor

There is a significant role of using hydrogen in engines than pure disesel, bio diesels. A combination of hydrogen at different flow rates and diesel can be used. Hydrogen tanks with storage capacity is used in vehicle which is very dangerous, so here we include a hydrogen reactor in which chemicals are mixed
to produce hydrogen and can be sent to the engine along with diesel. In this work, an on-demand hydrogen generation setup was used to generate hydrogen for the purpose of burning it in the engine along with diesel under dual fuel mode. A solid-state hydrogen generation mechanism was employed in a purpose-built reactor using Sodium Borohydride (NaBH4) and Aluminium Sulphate (Al2(SO4)3) mixed in water. The experimentation was done on 4 S VCR diesel engine with single cylinder which was modified into duel fuel mode. The studies were carried with pure diesel and hydrogen at 15lit per min at 16, 17 and 18 compression ratioby holding speed to be 1500 rpm with varied loads from 0 to 12 kg with an interval of 3 kg. The cylinder pressure got increased, performance parameters like brake thermal efficiency got enhanced due to the usage of hydrogen than pure diesel. The emission parameter such as
nitrogen oxide increased when hydrogen was injected
