“…Similar values of fluid physical properties either for biodiesel or for standard diesel fuel can be found in the literature. − The biodiesel has higher density, viscosity, and surface tension than the diesel fuel, and as expected, the properties of the mixture of 30% of biodiesel are between those of regular diesel and rape methyl ester fuels (RME). In addition, since these three fuels have been made to work in real engines recently, they are in accordance with the international fuel standards requirements (EN 590 for Diesel fuels and EN 14214 for biodiesel fuel types).…”

This paper presents an experimental comparison of three biodiesel blends on DI diesel injection process using a standard injection system derived from a 4-stroke DI commercial diesel engine. Specifically, this work relies on several experiments carried out over a commercial diesel fuel, with 5.75% of rape methyl ester called B5, another with 30% of RME (B30), and a pure rape methyl ester fuel (called RME). Analyses on injection rate shape, spray force, spray tip penetration, and cone angle in nonevaporative conditions have been performed and studied to compare the effect of those different fuels over the injection process. A better understanding of injection process will be useful to achieve a better comprehension of mixing process which determines combustion and emissions in a compression ignition engine. It is well-known that fuel properties like density or kinematic viscosity are higher in vegetable oils and strongly affect how injection system operates. An increase in the hydraulic delay and a higher mass flow rate have been observed in injection rate measurements when using biodiesel; macrovisualization showed that the biodiesel fuel has slightly longer penetration and narrower cone angle that leads to smaller spray volumes.

“…The American Society for Testing and Materials details that biodiesel is a fuel which contains mono alkyl esters of long-chain fatty acids produces from renewable lipid feedstock [9]. Renewable and sustainable fuels, such as oil obtained from vegetables, seeds, and fats, are required as the best substitution for the fossil fuel [10,11].…”

Nitrogen dioxide (NO2) is the ubiquitous chemical structure of NOx in the ambience that is initiated by anthropogenic (human) acts. NO2 is also reacts in the surrounding to result in ozone (O3) and the main culprits for acid rain. Captured proportion of NOx by moisture forms acid rain. Acid rain severely affects certain ecosystems. The facts mentioned indicate necessity to reduce NOx pollution. When any of these oxides disintegrate in H2O and breakup, they result in nitric acid (HNO3) or nitrous acid (HNO2). Automobiles is one of the major sources of the NOx that is emitted. Here in this experimental based research effort has been made to reduce emissions of NOx and CO emitted by the diesel based engine powered by Madhuca longifolia as a biodiesel blended with diesel (B10, B20, B30) by injecting water after exhaust gas manifold to get reaction so as oxides disintegrate in H2O and breakup, they result in nitric acid (HNO3) or nitrous acid (HNO2). Experimental work conducted on Mono-cylinder CRDI engine. Trials were taken with different blends of Madhuca longifolia by setting CR 15,16, 17 and 18 with water injected at 3 different mass flow rates (38.7, 82.7, 130.4 CC/min). Results shows average reduction in NOx by 7.89%, 12.26%, and 17.73% respectively.

“…Of the alternative fuels, biodiesel obtained from vegetable oils holds good promises as an eco-friendly alternative to diesel fuel [4]. The American Society for Testing and Materials (ASTM) defines biodiesel fuel as mono alkyl esters of long chain fatty acids derived from a renewable feed stock such as vegetable oil or animal fat [5]. The experimental results of various researchers support the use of biodiesel as a viable alternative to the diesel oil for use in the internal combustion engines.…”

Energy is one of the major inputs for the economic development of any country. In the case of the developing countries, the energy sector assumes a critical importance in view of the ever-increasing energy needs requiring huge investments to meet them. For the developing country like India, economic growth is desirable and energy is essential for economic growth. The situation has led to the search for an alternative fuel, which should be not only sustainable but also environment friendly. For developing countries, fuels of bio-origin, such as alcohol, vegetable oils, biomass, biogas, synthetic fuels, etc. are becoming important. For the present work, Experimental investigations on long term storage issues of Vegetable Oil and Biodiesel fuel is carried out. Long-term storage study gives us a better understanding of the effect of the storage condition on the stability of biodiesel.
