Abstract: In this era of depleting fossil fuels, alternative fuels and their study has gained much importance. One of the methods of using alternative fuels is operating the IC engines in dual fuel mode. This review is an attempt to highlight the investigations on the HHO gas supplemented combustion in the internal combustion engines, particularly the diesel operated ones. HHO gas has better burning characteristics than pure hydrogen since, hydrogen and oxygen does not attain the diatomic state. Hence, ideally HHO gas is having higher energy releasing capability. HHO inducted systems show better performance than that of the ordinary diesel engines in terms of brake thermal efficiency, specific fuel consumption and engine torque. However, the volumetric efficiency of these systems are relatively lesser. HHO inducted systems also show better emission characteristics. The emission of CO and unburned hydrocarbons are almost reduced by 30-40%. One of the major disadvantages of using HHO gas is the possible increase in NOx emission.

Keywords: dry cell electrolyser; HHO gas; dual fuel.
