The engines being used for power generation using producer gas are essentially derived from diesel frame, suitably adapted for gas fuelled operation. With engines designed for conventional fuels being used for operation with producer gas, a detailed investigation spanning a broad range of operational aspects is essential. While experimental investigations provide actual performance parameters, the information is essential spatial or temporal average only. Apart from that, fluid dynamic and combustion progress parameters cannot be acquired inexpensively. The current work involves simulating the engine on motored condition considering only air using ANSYS FLUENT computational fluid dynamics software. Further work is carried out on producer gas as a fuel at different equivalence ratio and pressure, temperature distributions in the cylinder during all the four reciprocating strokes of the engine at discrete crank angles is well captured under turbocharged after cooled mode. Initially the grid independence of the developed mesh is established and subsequently initial conditions derived from experimental investigations are used for simulation. The brake power obtained from the simulation is compared with the experimental brake power at the desired condition. Once simulation is validated, effort is extended for varying equivalence ratios and the results reported.
