Abstract

This paper highlights the impact of turbocharger and addition of producer gas flow rate on the emissions of  a twin cylinder diesel engine fuelled with diesel and  blends of neat Karanja oil (10% and 20%) with diesel (on weight basis). The test is carried out with and without turbocharged mode in two cases of operations. In case 1, the above fuels are tested at an optimum gas flow rate of 21.49 kg/hr under different engine loading conditions. In case 2, the same fuels are tested at an optimum load of 10 kW under different gas flow rates. During turbo mode operation it is found that mixing of inlet air and producer gas becomes a difficult issue due to their pressure difference and hence a proper arrangement is needed for it. The study reveals that the turbocharged mode operations of all the tested fuels show a significant reduction of hydrocarbon, carbon monoxide and smoke opacity. However, with increase in gas flow rate up to an optimum level, the nitrogen oxide emission and smoke opacity decreases significantly. At an optimum gas flow rate of 21.49 kg/hr, producer gas can be used as a potential fuel for diesel to reduce emissions.
