The study on the performance and emission characteristics was done using various isopropyl alcohol -diesel blends. Two blends were made IPA-25 and IPA-35 and their characteristics were investigated with respect to diesel(IPAO). The study led to the following conclusions:The isopropyl alcohol and diesel blend was stable i.e.
it was miscible in diesel.The BSFC of the blends have increased due to higher demand of power and less availability of energy. The BSFC decreased with increasing load condition.The BTE increased with the increase in blend ratio and also with the increment in load due to better availability or enrichment of oxygen in fuel.
The NOx emissions increased for both IPA -25 and IPA-35 at idle and peak load conditions whereas it is decreased at medium load conditions for both the blends.A decrease in CO2 emissions for IPA-35 was found at idle and medium load condition. Whereas for IPA-25 it is increased at idle state and for rest of the loads it remained the same as that of diesel.HC and CO showed increment for both the blends at all loads. Only CO remained stable at peak load conditions for both the blends.As an outcome of all the study on the engine 35% blend i.e.
IPA-35 can be used dur to better BTE and decreasing some emissions but should be used with improvements in the HC And CO emissions.REFRENCES1 Ashish Kumar Singh, Chinmaya Mishra, Vipul Vibhanshu and Naveen kumar, Performance Evaluation and Emission Studies of a Single Cylinder Diesel Engine Fuelled with Isopropyl Alcohol and Diesel, 2013, SAE Technical Paper 2013-01-1132, 2013.2 Ashraf Elfasakhany, Investigations on the effects of ethanol-methanol gasoline blends in a spark ignition engine: performance and emission analysis, 2015, EST Journal.3 Ajay Singh Verma, A., Hasan, M.
