Abstract: This article is focused to analyze the effects in engine operations when different alternative fuels jointly used. Normally biogas from pure sago sludge composed with Hydrogen sulfide (H2S) which lead severe corrosion in engine parts. To reduce this effect, poultry manure (70 wt %) was mixed with sago sludge (30 wt %) for production of biogas. At maximum load, the brake thermal efficiency was found reduced up to 12 % with DTPO30 + biogas and 17 % with diesel + biogas compared to normal diesel operations. The brake specific fuel consumption was higher up to 10 % with distilled tire pyrolysis oil (DTPO30) with biogas operations than diesel with biogas. Reduced NOx about 27 % with DTPO30+ biogas and 21 % with diesel+ biogas than diesel operations. Correspondingly, increased CO was reported with dual fuel mode due to CO2 presence with biogas. Also, increased hydrocarbon and reduced smoke opacity with biogas operations were reported. The H2S effect on engine operation was reduced hence it can increase the engine reliability.
