Abstract
In this present study, a single cylinder, four stroke, water cooled diesel engine was converted to dual fuel system which operated with either diesel fuel or blend with CNG (Compressed natural gas) using an electronically controlled solenoid actuated valve mechanism. The pollutants of the engines (carbon mono-oxide, carbon dioxides, unburnt hydrocarbon, oxides of nitrogen and smoke) were measured at 0%,25%,50%,75% and 100% load through a AVL five gas analyser and smoke meter. The experimental results showed significant reduction in CO, CO2, NOX, and Smoke at full load while the engine was fueled with blend with CNG compared to that with the diesel fuel. Whereas, Unburnt hydrocarbon was comparable with diesel fuel.
