Exhaust Gas Recirculation (EGR) without intercooler is being used widely to reduce and control the oxides of nitrogen (NOx) emission from diesel engines. EGR controls the NOx because it lowers oxygen concentration and flame temperature of the working fluid in the combustion chamber. However, the use of EGR without intercooler leads to a trade- off in terms of soot emissions moreover it exhausted more unburned hydrocarbons (25–35%) compared to conventional engines. Present experimental study has been carried out to investigate the effect of EGR on performance and emissions in twin cylinders, air cooled and constant speed direct injection diesel engine, which is typically used in genset. Such engines are normally not operated with EGR. The experiments were carried out to experimentally evaluate the performance and emissions for different EGR rates of the engine. Emissions of hydrocarbon (HC), NOx, carbon monoxide (CO) were measured. Performance parameters such as thermal efficiency, brake specific fuel consumption(BSFC) were calculated.

Key words: Waste cooking oil, Diesel Engine, EGR
