The main purpose of this research work is to evaluate the predicted values for the corrected Brake power (BP) and corrected specific fuel consumption (SFC) of single cylinder VCR diesel engine operated on diesel and jatropha biodiesel blend (0%, 25%, 50%, 75%, 100%) derived from jatropha curcas oil. Current research work concentrates on the performance parameters of engine 4 stroke single cylinder CI engine, carried out using ISO 10000 approach in which the brake power and specific fuel consumption are corrected via correction factors “α‟ & “β‟ respectively. Also examine combined effect of brake power at various blends and loads in order to find out optimal performance of CI engine by conducting experiments as per IS 10000 method. The experimental work will be used to find out load and blend ratio for optimal brake power and lower specific fuel consumption by using Taguchi’s approach using Minitab software. A set of experiments have been performed as suggested by the software. Engine variable such as loads and blend ratio (Diesel + % JBD) are the most significant variables for brake power at specific fuel consumptions. After experiments, it is reported that the optimized parameters for corrected BP (2.95 KW) are at 100% blend and 10 kg of engine load, and optimized parameter for corrected SFC (0.26 kg/KWh) are at 0% blend and 10 kg engine.

Biodiesel is an alternative fuels for diesel engine with the blending process by chemically combination of vegetable or animal oil and diesel fuels. It is proved that the biodiesel can be used without any modification on the compression ignition (CI) engine. In this study, the cooking oil of namely carotene is used to produce the biodiesel blend fuels in various percentages. The biodiesel blend and diesel fuel are evaluated to analyze the engine performances in 4 cylinder inline CI engine. The characteristics of engine performances namely brake power output and brake specific fuel consumption are measured with various loads applied. The fuel properties of biodiesel blend are investigated namely density, dynamics viscosity and kinetic viscosity. The experimental results show that the performance of biodiesel B10 is better than it counterpart namely diesel in terms of brake power output and brake specific fuel consumption (BSFC).

The objective of this project was to develop both engine performance and emission profiles for two test fuels — a 6% water-in-diesel oil emulsion (DOE-6) fuel and a neat diesel (D100) fuel. The testing was performed on a single cylinder, direct-injection, water-cooled diesel engine coupled to an eddy current dynamometer. Output parameters of the engine were used to calculate Brake Specific Fuel Consumption (BSFC) and Engine Efficiency (η) for each test fuel. DOE-6 fuels generated a 24% reduction in NOX and a 42% reduction in Carbon Monoxide emissions over the tested operating conditions. DOE-6 fuels presented higher ignition delays — between 1°-4°, yielded 1%–12% lower peak cylinder pressures and produced up to 5.5% lower exhaust temperatures. Brake Specific Fuel consumption increased by 6.6% for the DOE-6 fuels as compared to the D100 fuels. This project is the first research done by a New Zealand academic institution on water-in-diesel emulsion fuels.

The performance of engine fueled with diesel/biodiesel blends was tested. It was indicated from the experimental results that the brake power, torque out and brake specific fuel consumption of engine fueled with diesel/biodiesel caused slight variations, while NOx emission increased significantly compared with engine fueled with diesel. In order to reduce NOx emission of engine fueled with pure biodiesel, retarding fuel delivery advance angle was used, and the NOx emission tests revealed that the NOx emission decreased significantly at different engine speeds.

The rising global warming concerns and explosive degradation of the environment requires the mainstream utilization of alternative fuels, such as hydroxy gas (HHO) which presents itself as a viable substitute for extracting the benefits of hydrogen. Therefore, an experimental study of the performance and emission characteristics of alternative fuels in contrast to conventional gasoline was undertaken. For experimentation, a spark ignition engine was run on a multitude of fuels comprising of gasoline, Liquefied petroleum gas (LPG) and hybrid blend of HHO with LPG. The engine was operated at 60% open throttle with engine speed ranging from 1600 rpm to 3400 rpm. Simultaneously, the corresponding performance parameters including brake specific fuel consumption, brake power and brake thermal efficiency were investigated. Emission levels of CO, CO2, HC and NOx were quantified in the specified speed range. To check the suitability of the acquired experimental data, it was subjected to a Weibull distribution fit. Enhanced performance efficiency and reduced emissions were observed with the combustion of the hybrid mixture of LPG with HHO in comparison to LPG: on average, brake power increased by 7% while the brake specific fuel consumption reduced by 15%. On the other hand, emissions relative to LPG decreased by 21%, 9% and 21.8% in cases of CO, CO2, and unburned hydrocarbons respectively. Incorporating alternative fuels would not only imply reduced dependency on conventional fuels but would also contribute to their sustainability for future generations. Simultaneously, the decrease in harmful environmental pollutants would help to mitigate and combat the threats of climate change.

This paper presents outcomes of the usage of a developed prototype of PFI retrofit-kit for small 4-stroke gasoline engine. The developed PFI retrofit-kit produced good and high brake power and brake mean effective pressure compared to the carburetor system with over 50% improvement. Exhaust-out emissions such as carbon monoxide, carbon dioxide and hydrocarbon have been reduced in the range of 39%, 185%, and 57% respectively. However, brake specific fuel consumption was found to be higher (125%) as compared to carburetor system.

Current targets in reducing CO2 and other greenhouse gases as well as fossil fuel depletion have promoted the research for alternatives to petroleum-based fuels. Pyrolysis oil (PO) from biomass and waste oil is seen as a method to reduce life-cycle CO2, broaden the energy mix and increase the use of renewable fuels. The abundancy and low prices of feedstock have attracted the attention of biomass pyrolysis in order to obtain energy-dense products. Research has been carried out in optimising the pyrolysis process, finding efficient ways to convert the waste to energy. However, the pyrolysis products have a high content in water, high viscosity and high corrosiveness which makes them unsuitable for engine combustion. Upgrading processes such as gasification, trans-esterification or hydro-deoxynegation are then needed. These processes are normally costly and require high energy input. Thus, emulsification in fossil fuels or alcohols is being used as an alternative. In this research work, the feasibility of using PO-diesel emulsion in a single-cylinder diesel engine has been investigated. In-cylinder pressure, regulated gaseous emissions, particulate matter, fuel consumption and lubricity analysis reported. The tests were carried out of a stable non-corrosive wood pyrolysis product produced by Future Blends Ltd of Milton Park, Oxfordshire, UK. The product is trademarked by FBL, and is a stabilized fraction of raw pyrolysis oil produced in a process for which the patent is pending. The results show an increase in gaseous emissions, fuel consumption and a reduction in soot. The combustion was delayed with the emulsified fuel and a high variability was observed during engine operation.


In this study, the performance, combustion and emissions characteristics of compression ignition engine were calculated and analysed using a waste agricultural biodiesel . The tests were performed at steady state conditions for a four-stroke single cylinder diesel engine loaded at engine speed of 1500 rpm. The present experimental investigation evaluates the effects of using BD20 blend of biodiesel. During experimental testing of CI engine using biofuel blend, the engine was maintained at various compression ratio i.e., 18, 19 and 20 respectively. Engine load is varied from zero to full load condition. Design of experiment is done with Taguchi method. The main objective is to check the optimum compression ratio and to obtain minimum specific fuel consumption, better efficiency and lesser emission with higher compression ratio. Results shows that Brake thermal efficiency and cylinder pressure of CI engine increases with increase in compression ratio and load. Specific fuel consumption, emission of hydrocarbon and carbon monoxide decreases as we increase compression ratio. Nitrogen oxide follows the reverse trend and found to be increased as we increase compression ratio and load on engine. The analysis shows optimum performance with lower emission at a CR of 20 and load 100%.
