Experimental Investigation of Diesel – Ethanol Blend in DI Diesel Engine Using Preheating of Intake Air
Abstract:
Effect of preheat intake air were investigated on performance and emission characteristic of a compression ignition engine running on fuel of diesel (70%)-ethanol (30%). Fuel was evaluated within the engine twist with intake air temperature at 30°C and 60˚ respectively. Performance and emission characteristic of the diesel engine are compared based on diesel-ethanol blend, with and without preheat. The resulting emission indicated that the high heat of vaporization of ethanol affect CO and HC emission considerably. Preheating the intake air diesel-ethanol blend tends to reduce the production of CO and HC whereas increasing NOx emission.
