Operation and Combustion Characteristics of a DI Diesel Engine Fueled with Biomass Oil-Diesel Fuel Blends 2001-28-0030

This paper presents further investigation into the effects of using biomass oil-diesel fuel blends on the characteristics of operation and emissions in a production DI diesel engine. Neat coconut oil was chosen in terms of its beneficial property of chemical stability and agricultural productivity. The spray characteristics were evaluated with a phase doppler anemometer. Operation of the test engine was shown to be successful even without any engine modification. Results show that neat coconut oil operation gave lower smoke and NOx emissions. The mechanism of these effects are discussed.
