摘要：The purpose of this research work is to study the effectiveness of hydroxy (HHO) gas as an additiveto a conventional four stroke, twin cylinder, direct injection (DI) compression ignition (CI) engine withoutany modification and need of a storage tank. Here HHO gas was produced by the electrolysis process of threedifferent electrolytes such as (KOH(aq), NaOH(aq), K2CO3(aq)) with the electrode material built up of mixedmetal oxide (MMO) coated titanium plates in a dry cell type HHO gas kit. In this experimental investigation,the HHO gas produced at a steady flow rate of 0.45 lpm was mixed with the inlet air after the air filter at the inletmanifold. The performance and exhaust emission tests were conducted at a constant engine speed of 1500 rpm,resulting into increase in brake thermal efficiency (η B.T.) and volumetric efficiency (η Vol.), whereas there is a dropin the brake specific fuel consumption (BSFC), indicated mean effective pressure (IMEP) of the diesel engine.There was also some decline in the curves of carbon monoxide (CO), unburned hydrocarbon (UBHC) and nitrogenmonoxide (NO) emissions. When comparing among these three different electrolytes which were added into thewater to diminish hydrogen and oxygen bonds, to form HHO gas, KOH(aq) was specified as the most appropriateelectrolyte, as it gave better performance and emission results.
