Biodiesel produced from pongamia oil has been considered as promising option for diesel engines because of its environmental friendliness. In this work, bio-diesel from pongamia oil is prepared (PME 100), tested on a diesel engine for different blends such as PME 20, PME 40, PME 60 and PME 80. Comparison is made with diesel operation. Parameters such as brake thermal efficiency, brake specific fuel consumption, carbon monoxide, unburned hydrocarbons, smoke and NOx emissions are evaluated. Even though the performance reduces slightly when the engine is fueled with biodiesel, significant changes in the combustion parameters observed in case of biodiesel blends are significant to note. On the other hand, reduction in CO, HC and smoke is observed. Study reveals the effect of bio-diesel on a DI engine when compared to diesel and evolves conclusions with respect to performance and emissions. © 2014 Faculty of Engineering, Ain Shams University.

Experimental Investigations on a Direct Injection Diesel Engine Fuelled With Mixed Biodiesel

The present research deals with study of pongamia oil methyl ester as a lubricant by blending with anti-wear additive ZDDP. The experimental work carried in this work aims to investigates the friction and wear characteristics by blending zinc diakyldithio phosphates (ZDDP) with pongamia oil methyl ester as lubricant under various loading conditions and temperatures. The coefficient of friction and wear scar depth were determined using pongamia biodiesel blended with 0.3%, 0.6% and 1 % ZDDP by concentration through high frequency reciprocating wear testing machine for 2 h duration. The reciprocating wear tests were performed on an engine liner-piston ring contact under the loads of 40 N, 60 N and 80 N for 2 h duration at temperatures of 100°C, 125°C 150° C with 10 Hz oscillation frequency. The addition of ZDDP with pongamia biodiesel showed marginal reduction in friction coefficient and wear scar depth under all loads and temperatures. The coefficient of friction was found to be higher in the initial stages due to running-in for all testing conditions. In addition, the SEM images of tested specimens were also examined. The presence of deep grooves at certain locations on the specimens was observed that might have caused due to simultaneous effect of fatigue and adhesive wear. Further, the addition of ZDDP with pongamia biodiesel has not affected the formation of an antiwear tribofilm. © Copyright (c) 2017 SAE International and Copyright (c) 2017 SAE INDIA.

Tribological Characteristics of Zinc Diakyldithio Phosphates Blended with Pongamia Biodiesel

The present research work has embarked on to exploit the novel renewable and biodegradable source of energy from lemon fruit rinds. A systematic approach has been made in this study to find the suitability of lemon peel oil for internal combustion engines and gensets applications. Extracted lemon peel oil is found to exhibit comparatively very low viscosity, flash point and boiling point than that of conventional diesel. Various blends of lemon peel oil have been prepared with conventional diesel with volumetric concentration of 20%, 40%, 50% and 100% and their physical and chemical properties are evaluated for its suitability in direct injection diesel engine. Lower cetane index of lemon peel oil significantly influences the ignition delay period and peak heat release rate that lead to the penalty in NOx emissions. Interestingly, the diesel engine performance characteristics have been improved to a remarkable level with higher proportions of lemon peel oil in the blends. In addition, the reduction of BSCO, BSHC and smoke emission is proportional to the lemon oil concentration in the blends. Overall diesel engine characteristics indicated that lemon peel oil can partially or completely replace the petroleum diesel usage to a great extent in developing countries like India. © 2017 Elsevier Ltd

Lemon peel oil – A novel renewable alternative energy source for diesel engine

The trend of using biodiesels in compression ignition engines have been the focus in recent decades due to the promising environmental factors and depletion of fossil fuel reserves. This work presents the effect of Calophyllum inophyllum methyl ester on diesel engine performance, emission and combustion characteristics at different injection pressures. Experimental investigations with varying injection pressures of 200 bar, 220 bar and 240 bar have been carried out to analyse the parameters like brake thermal efficiency, specific fuel consumption, heat release rate and engine emissions of direct injection diesel engine fuelled with 100% biodiesel and compared with neat diesel. The experimental results revealed that brake specific fuel consumption of C. inophyllum methyl ester fuelled engine has been reduced to a great extent with higher injection pressure. Significant reduction in emissions of unburnt hydrocarbons, carbon monoxide and smoke opacity have been observed during fuel injection of biodiesel at 220 bar compared to other fuel injection pressures. However oxides of nitrogen increased with increase in injection pressures of C. inophyllum methyl ester and are always higher than that of neat diesel. In addition the combustion characteristics of biodiesel at all injection pressures followed a similar trend to that of conventional diesel. © 2016 Elsevier Ltd. All rights reserved.

A comparative study on lubricating oil degradation is carried out to assess the durability of a single cylinder diesel engine fuelled by biodiesel blend (20 per cent) and diesel, respectively. Initially, the engine is made to run with diesel for 256 h, each cycle comprising 16 h as per the IS 10000 standards. The same test cycle has been carried out on the engine which was later fuelled with biodiesel. Various tribological properties of lubricating oil such as kinematic viscosity, density, total base number, moisture content, ash content, pentane and benzene insoluble are recorded at regular intervals in order to correlate the effect of fuel chemistry on lubricating oil performance and engine life. Kinematic viscosity, flash point and total base number were observed to be lesser in biodiesel blend fuelled engine. Density, ash content, moisture content and insoluble were found to be higher in biodiesel engine. Wear debris concentrations in the lubricating oil samples drawn from both the engines were measured by Inductive Coupled Plasma-Atomic Emission Spectroscopy. Higher wear metal concentrations were observed in the lubricating oil of PME20 fuelled engine. Surface roughness parameters of cylinder liners were investigated and compared to quantify the cylinder wear of both engines. Ferrography tests of lubricating oils also indicated the significant deterioration of lubricating oil in biodiesel blend fuelled engine. © 2015 Elsevier Ltd. All rights reserved.
