An experimental investigation on engine performance, emissions, combustion and vibration characteristics with coconut biodiesel fuels was conducted in a high-pressure common-rail diesel engine under five different load operations (0.17, 0.34, 0.52, 0.69 and 0.86 MPa). The test fuels included a conventional diesel fuel and four different fuel blends of coconut biodiesel (B10, B20, B30 and B50). ...

In this study, preheated crude sunflower oil at 75C was used in a fourcylinder, naturally aspirated, indirect injection diesel engine. The experiments were conducted at the constant engine speeds under the full load condition of the engine to determine the performance, combustion, and injection characteristics of test fuels. The engine test results have been compared with the reference values t...

In this study, energy and exergy analysis were performed for a single cylinder, water-cooled diesel engine using biodiesel, diesel and bioethanol blends. Each experiment was performed at twelve different engine speeds between 1000 and 3000 rev/min at intervals of 200 rev/min for four different fuel blends. The fuel blends, prepared by mixing biodiesel and diesel in different proportions fuel wi...

The present work presents the comparative simulation of a diesel engine fuelled on diesel fuel and biodiesel fuel. Two models, based on tabulated chemistry, were implemented for the simulation purpose and results were compared with experimental data obtained from a single cylinder diesel engine. The first model is a single zone model based on the Krieger and Bormann combustion model while the s...

This investigation is an effort to find best optimization method for diesel engine using blended fuel. Present time, the scarcity of fossil fuel is a serious problem all over the world. So, researchers are trying to find best alternative fuel for that conventional fuel. When we use alternate fuel in diesel engine, we must have to optimize the parameter of diesel engine. The present trend will b...

The aim of the present research work is to investigate the influence of Jatropha biodiesel properties on various characteristics of a direct injection compression ignition engine. The experiments were performed at different engine operating regimes with the injection timing prescribed by the engine manufacturer for diesel fuel. The engine characteristics with Jatropha biodiesel were compared ag...

In order to investigate the effects ethanol-diesel blends and altitude on the performance and emissions of diesel engine, the comparative experiments were carried out on the bench of turbo-charged diesel engine fueled with pure diesel (as prototype) and ethanol-diesel blends (E10, E15, E20 and E30) under different atmospheric pressures (81 kPa, 90 kPa and 100 kPa). The experimental results indi...

There are concerns that biodiesel feedstock may compete with food supply in the long term, if the raw materials are vegetable virgin oils only. Therefore, throughout the world, large amounts of non-edible oil plants are available in nature. In this paper, experimental study has been carried out to analyze engine performance and emission characteristics for direct injection diesel engine using b...

In this paper, a combustion analysis of a compression ignition (CI) engine operating with biodiesel blends has been experimentally investigated to examine the effects of biodiesel on the combustion process and the characteristics of the engine noise produced by the combustion process. The experiment with different loads and speeds was conducted on a four-cylinder, four-stroke, direct injection ...
