1-This investigation establishes that hydrogen can be utilized in compression ignition engines operating them on dual-fuel principle.
2-Such operation improves thermal efficiency, makes the engine run with very lean equivalence ratios, which means very low engine emissions.
3-This operation results in lower exhaust gas temperatures leading to longer live of components such as exhaust valves.
4-Increasing hydrogen volumetric fractions accompanied with injection timing retarding, due to increasing in the flame velocity till the air is completely utilized. Further increase in HVF causes knock to appear, and OIT must be retarded sharply, which reduce the bp resulted from engine.
5-Knocking in the engine limits the proportion of energy input that can be supplied through hydrogen. The occurrence of knock in this type of hydrogen addition operation may be due to hydrogen rapid rate of pressure rise or flaming particle that is left behind due to bad engine scavenging.
6-When engine was run with hydrogen addition, bp was improved. The effect of hydrogen addition on the power enhancement was not quantitatively but qualitatively by the means of combustion improvement
