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…

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…

This paper aims at studying the effect of oxygen enriched combustion on performance, emission and combustion characteristics of a diesel engine using the blend of Pyro oil obtained from pyrolysis of cashew nut shell and conventional diesel as fuel. A single cylinder water-cooled, diesel engine was used. The intake system of the engine was modified to accommodate excess oxygen in the incoming air. A separate oxygen cylinder was used for storing pure oxygen and supplying it along with intake air. Base line data was generated using diesel as fuel. Subsequently experiments were repeated with the blend of 40% of Cashew nut shell oil and 60% diesel by volume (called CSO40D60) at different oxygen concentrations such as 21%, 22% 23%, 24% and 25%. Engine performance, emission and combustion parameters were obtained at different power outputs and analyzed. At ambient oxygen condition (i.e. 21%) the test results showed reduced brake thermal efficiency, higher smoke, hydrocarbon and carbon monoxide emissions with CSO40D60 as compared to neat diesel at all power outputs. The brake thermal efficiency was found as…
