Performance and Emission Characteristics of Cashew Nut Shell Pyrolysed Oil - Waste Cooking Oil With Diesel Fuel in a Four Stoke Di Diesel Engine

India is considered as the fourth largest energy co nsumer in the world after the United States, China, a nd Russia. India’s energy consumption is increasing in a relatively faster rate in the recent years due to p pulation growth and economic development of the country. This work f ocuses on the performance of waste cooking oil and Cashew nut shell pyrolysis oil blend with diesel fuel used in a four stoke diesel engine. The pyrolysis process was used to extract the cashew nut shell pyro oil from the Cashew nut shell bi o mass. The Cashew nut shell biomass was used at the r eaction temperature of 800 C to obtain cashew shell pyro oil from fast pyrolysis process. The Cashew shell pyro oil and waste cooking oil properties were studied. The blending of pyrolysis oil and waste cooking oil is done by mix ing of diesel fuel by volume called as CPO5WC5D90 (5%CPO+5%WC+90D), CPO10WC5D8 5 (10%CPO+5%WC+85%D) and CPO15WC5D80 (15% CPO + 5%WC + 80% D). Characteristics o f a fuel for Diesel fuel, and blending of CPO5WC5D90, CPO10WC5D85 and CPO15WC5D80 were analyzed. All the blen ded fuels were tested in a 1500 rpm single cylinder four stroke diesel engine for their performance as blend d fuel. Engine test results showed that the perform ance for all CPO5WC5D90, CPO10WC5D85 and CPO15WC5D80related to diesel fuel. At the
