The Performance of Four Stroke Surface Ignition Ceramic Heater C.I. Engine using Ethanol-Diesel Blend

摘要

In this paper an experimental investigation on the performance of four stroke C.I.engine fueled with pure diesel (B0D100E0) and ethanol-diesel blends containing 10%, 20%, 25% and 30% by volume of ethanol (E) are evaluated. Formaldehyde (B) additive is used to solubility of ethanol indiesel that acts as a bridging agent and bonding to produce a homogeneous blend.The tests are carried out on a ceramic heater10KW single cylinder diesel engine under steady state operating conditions on two specified speeds of 1500 rpm and 2000.rpm. The Partially Stabilized Zirconia (PSZ) ceramic heater is used to reduce the emissions from the engine and improve engine output behavior. The relevant parameters such as brake thermal efficiency (BTE), break specific fuel consumption (BSFC) and emissions are calculated for ethanol-diesel blends by B5D85E10, B5D75E20, B5D70E25and B5D65E30. The PSZ ceramic heater is used to reduce the emissions by 38% of NOx, under half load condition for the blends of B5D85E10 gives minimum CO emissions and unburned HC emissions by 7.5ppm from the engine and improve engine output behavior to 1.8%.
