Waste Cooking Oil (WCO) is generated in large quantity worldwide due to the increase in population and change of food habits. This work is about utilizing this WCO as an alternative fuel for Compression Ignition (CI) engine, in view of addressing the constraints in the domain of land as well as air pollution. A fuel and engine level modification were carried out to analyse the behaviour of the test engine. In the first phase of the study, collected WCO was converted into its methyl esters (i.e. WCOME) and tested for its properties. A single cylinder, water cooled, direct injection, compression ignition engine was developed with suitable emission and combustion parameters computing equipments in the second phase of the work. In the third phase of the work, the developed engine was tested with neat diesel, WCO and WCOME under different engine power outputs.WCOME was converted into its emulsion (WCOMEE) and tested in the developed engine in the fourth phase of the work. In the fifth phase of the study, combustion chamber components like piston, cylinder head…

One of the globally challenging issues today is Waste Utilization. The excessive accumulation of waste has created an uncomfortable pressure on not, just the habitant but on the environment as well. As a small step forward in contributing towards minimizing waste disposal, this study attempts to address the problem raised due to the disposal of waste cooking oil. Researchers found that Waste Cooking Oil (WCO) has a very good potential as a fuel for compression ignition engine and was therefore selected for this study. In the first phase of the work, behaviour of the test engine was studied with neat WCO at different power outputs. As the first modification, neat WCO was converted in to its methyl ester and tested in the same engine. Next, combustion chamber parts like piston and cylinder head, inlet and exhaust valves were coated with Thermal Barrier Coating (TBC) and engine behaviour was studied. To make the study more interesting a thermal- stress analysis was done on the engine piston to examine the impact of coating on engine performance. Results…

Published 2018-04-03 by SAE International in United States
Depletion of fossil fuels and amendment of strict emission norms demand for the development of new technologies in ensuring effective utilization of existing renewable energy resources. Nanotechnology is one such new tool which finds wide application in automobile industries. Light weight in nature, high degree of durability, toughness and wear resistance makes the usage of nanomaterials wide spread. In view of above points, an attempt was made in this study to experimentally investigate the effect of inclusion of Nano fluids on the behavior of a compression ignition engine fuelled with diesel biofuel blends. In this work Cashew Nut Shell Oil (CNSO) is chosen as the biofuel as its calorific value found to be very close to diesel. Initially CNSO and Neat Diesel (ND) are blended at different proportion and CNSO40 is claimed as the best blend as it holds a stability period of more than a week. In the second phase of the work engine was tested for its performance, emission and combustion behavior with ND and CNSO40 at 20%, 40%, 60%, 80% and 100%…

Comparative Study on Smoke Emission Control Strategies of a Variable Compression Ratio Engine Fueled with Waste Cooking Oil

Hindustan Institute of Technoloy & Science-Selvakumar Raja, Jaikumar Mayakrishnan, Sasikumar Nandagopal, Sangeethkumar Elumalai, Ramanathan Velmurugan
Published 2018-04-03 by SAE International in United States
This work involves a with comparative study of smoke emission reduction methods of a compression ignition engine fueled with neat Waste Cooking Oil (WCO). The test engine chosen for this study is an agricultural based single cylinder, with a variable compression ratio, which is water cooled and is of the direct injection compression ignition engine type. Initially the test engine was tested using with neat diesel and WCO using various load conditions with three different compression ratios, i.e., 16.5, 17.5 and 18 for its performance, emission and combustion behaviours respectively. Results revealed that, both diesel and neat WCO experienced higher Brake Thermal Efficiency (BTE) with increased compression ratio. Except for smoke emission, all other carbon based emissions of neat WCO was found to reduce with increased compression ratio. In view of the above identified problems, a fuel and engine level modification was carried out introduce to the best practice of operating the engine with least smoke emission. Emulsion and injection timings were chosen as two parameters, and their influence on the smoke emission of the…

Published 2018-04-03 by SAE International in United States
This work aims to discuss the practices required to address the effective utilization of Canola oil in compression ignition engine. Initially, raw canola oil was obtained using mortar and pestle method. In the second phase, transesterification of canola oil was done using methanol as the reacting agent and potassium hydroxide as the catalyst. The extracted biodiesel was then subjected to various standardization techniques and spectroscopic studies such as GC-MS (Gas Chromatography-Mass Spectroscopy), NMR (Nuclear Magnetic Resonance Spectroscopy) and FTIR (Fourier Transform Infrared Spectroscopy). In the third phase of the study, an engine test bench was developed with all suitable accessories. Instead of utilizing the neat form of canola biodiesel, an attempt was made to use the diesel and ethanol blends of canola biodiesel. The Variable load test was carried out using neat diesel and a best blend containing 30% by volume of canola biodiesel, 30% by volume of diesel and 40% by volume of ethanol (D30-CBD30-E40) at standard injection timing (i.e. 23oBTDC). In the next phase, the standard injection timing of best blend was advanced…

Published 2015-04-14 by SAE International in United States
This paper aims at studying the effect of oxygen enriched combustion on performance, emission and combustion characteristics of a diesel engine using waste cooking oil (WCO) derived from palm oil as fuel. A single cylinder water-cooled, direct injection diesel engine was used. The intake system of the engine was modified to accommodate excess oxygen in the incoming air. Base data was generated using diesel as fuel. Subsequently experiments were repeated with WCO for different oxygen concentrations such as 21% (WCO+21%O2), 23% (WCO+23%O2), 24% (WCO+24%O2) and 25% (WCO+25%O2) by volume. Engine performance, emission and combustion parameters were obtained at different power outputs and analyzed.Results showed reduced brake thermal efficiency, higher smoke, hydrocarbon and carbon monoxide emissions with WCO+21%O2 as compared to diesel at all power outputs. The brake thermal efficiency was found as 26.2% with WCO+21%O2 where as it was 30.5% with diesel at the rated power output of 3.7 kW. The smoke emission was noted as 75% and 40% respectively with WCO+21%O2 and diesel respectively. There is an improvement in brake thermal efficiency with the…
