Performance and Emissions of a Single Cylinder CI Engine Running on Corn Oil Methyl Ester-Diesel Blends

Abdülvahap Çakmak and Atilla Bilgin
Abstract—This document presents an experimental study on performance and emissions of a single cylinder, direct injection CI engine fueled with corn oil methyl ester-diesel blends. The blend fuels contain corn oil methyl ester with ratios of 10% (B10), 20% (B20) and 50% (B50) on volume basis, respectively. Engine experiments were carried out an existing test unit for five different engine speeds at full throttle position. The results showed a reduction in engine torque and brake specific fuel consumption (BSFC) with increasing biodiesel percentage in the blend fuels except for B10. Blend fuels result in higher thermal efficiency than diesel fuel. The mean thermal efficiency of the engine by using diesel, B10, B20 and B50 were determined as 37.57%, 38.95%, 38.19% and 38.22%, respectively. Also, blend fuels gave less CO and O2 emissions but higher NOx, HC and CO2 emissions compared to diesel fuel. It was calculated that NOx emissions of B10, B20 and B50 were 16.25, 9.48 and 38.84% higher than diesel fuels, respectively.

Index Terms—CI engine, corn oil methyl ester-diesel blends, engine performance, emissions.
