An experimental study is carried out to examine and analyze the influence of Di-Tertiary Butyl Peroxide in bioethanol diesel blends on the performance, combustion and emission characteristics in a single cylinder, 4-stroke, naturally aspirated, automotive diesel engine for variable speed at full load conditions. Esterified cotton seed oil of 5% by volume is emulsified with 95% pure diesel to get the base fuel (BE0) for the experiments. Bioethanol diesel blends are produced from base fuel by adding 5% and 10% pure ethanol on a volumetric basis to obtain BE5 and BE10 respectively. The bioethanol fuels are low in Cetane number and hence Di-Tertiary Butyl Peroxide a Cetane enhancer is added by 0.4% by volume to produce BE5CN0.4% and BE10CN0.4% emulsions respectively. It is found from the experiments carried out, that an inverse trend exists between brake thermal efficiency and percentage of ethanol in base fuel. This is due to the lower calorific value of ethanol and an improvement in brake thermal efficiency is observed with ignition improver added blends. The presence of Cetane improver significantly reduced oxides of nitrogen and unburned hydro carbon emissions for overall engine speed and carbon monoxide emissions for low to medium speed range. © 2016 Elsevier Ltd

Environmental concerns and rapid depletion of fossil fuels have caused interests in the study of alternative fuels for internal combustion (IC) engines. For internal combustion engines, ethanol fuel is receiving more attention because they are biodegradable, oxygenated and renewable fuels. This paper presents the experimental investigation to study the effect of fuel injection timing and intake air temperature using pure ethanol blended biodiesel fuel (B5E15), on the combustion and emission characteristics of a single cylinder, four-stroke, air cooled, direct injection diesel engine. The tests were carried out using B5E15 fuel under constant speed (1500 rpm) and load (2 kW) with different injection timing (12, 15, 18, 21 and 24° CA bTDC) and different intake air temperatures (40°C and 60°C) at 1.1 bar intake manifold pressure. The combustion and emission characteristics such as in-cylinder pressure, temperature, heat release, NOx, UHC, CO and smoke are presented and discussed. The experimental results reveal that advancing the injection timing results in increase in-cylinder pressure, temperature, heat release rate and NOx emissions. In addition, the CO and HC emissions exhibit a decreasing trend according to an increase in the intake air temperature and advance in the injection timing. The preheated intake air favours premixed combustion, resulting in increased peak cylinder pressure and heat release rates. © 2013 The Authors. Published by Elsevier Ltd.
