Properties and performance of cotton seed oil–diesel blends as a fuel for compression ignition engines

Abstract

This paper presents the evaluation of properties of straight vegetable cotton seed oil (CSO) and its blends with diesel fuel in various proportions to evaluate the performance and emission characteristics of a single cylinder compression ignition (CI) engine at constant speed of 1500rev∕min. Diesel and CSO oil fuel blends (10%, 30%, 50%, and 70%) were used to conduct engine performance and smoke emission tests at varying loads of 0%, 20%, 40%, 60%, 80%, and 100% of full load in addition to their straight CSO and diesel fuel. The performance parameters of brake specific energy consumption (BSFC), brake thermal efficiency (BTE), mechanical efficiency (ME), exhaust gas temperature (EGT), and exhaust emission (smoke) were evaluated to find the optimum CSO and diesel fuel blend. From the experimental results, the CSO10D90 blend fuel showed 3.7% reduction in BSFC, 1.7% increase in BTE, 6.7% increase in ME, and 21.7% reduction in the smoke emissions in comparison with conventional diesel operated engine. Finally, it is concluded that CSO10D90 can be used straight away in CI engines without any major modifications to the engine as it showed good performance and improved emission compared to all other fuels tested for the entire range of engine operation in comparison with diesel.

Effects of biodiesel from different feedstocks on engine performance and emissions: A review

“…The cetane number of biodiesel is higher than that of pure diesel due to its longer fatty acid carbon chains and the presence of saturation in molecules [70,89,90]. Generally, the higher the chain length, the higher the cetane number value [91]. The higher value in cetane number is considered to be a significant advantage in terms of engine performance and emissions, allowing biodiesel-fuelled engines to run more smoothly and with less noise [92].…”

Quantification of Execution and Emission Efficiency of a Fuelled Diesel Engine with Biodiesel

“…The CSO10D90 mix fuel recorded a 3.7 % decline in BSFC from the trial tests, a 1.7 % expansion in BTE, a 6.7 % expansion in ME, and a 21.7 % decrease in smoke emanations contrasted and conventional diesel motors. The creator presumed that CSO10D90 could be utilized promptly in CI motors with no noteworthy motor adjustments as it demonstrated great effectiveness and diminished emanations contrasted with every single other fuel tried for the whole motor activity contrasted with diesel [14].…”

Study on Performance & Emission Characteristic of CI Engine Using Biodiesel

“…Transesterification is a most common and well established chemical reaction in which alcohol reacts with triglycerides of fatty acids (vegetable oil) in the presence of catalyst to form glycerol and esters. The reaction is shown in Figure [5].…”
