The widespread use and consumption of crude oil draws the public's attention to the fate of petroleum hydrocarbons in the environment, as they can permeate the soil environment in an uncontrollable manner. Contamination of soils with petroleum products, including diesel oil (DO), can cause changes in the microbiological soil properties. The effect of diesel oil on the functional diversity of fu...

A number of studies currently focus on the renewable fuels to reduce the reliance on petroleum fuels. Biofuels such as biodiesel and bioethanol have been studied and tested in many countries including India. This paper is aimed to investigate the performance and emission characteristics of a direct injection (DI) diesel engine when fuelled with methyl ester of Jatropha oil (MEJO). The ignition ...

This paper presents the implementation of polynomial vector back propagation algorithm (PVBPA) for estimating the power, torque, specific fuel consumption and presence of carbon monoxide, hydrocarbons in the emission of a direct injection diesel engine. Experimental readings were obtained using the biodiesel prepared form the waste low quality cooking oil collected from the canteen of Sri Saira...

Nowadays, the increasing oil consumption throughout the world induces crucial economical, security, and environmental problems. As a result, intensive researches are undertaken to find appropriate substitution to fossil fuels. In view of the large amount of eucalyptus trees present in arid areas, we focus in this study on the investigation of using eucalyptus biodiesel as fuel in diesel engine....

Biodiesel, defined as monoalkyl esters of vegetable oils or animal fats (Scheme 1), is a promising alternative fuel for use in compression-ignition (diesel) engines and is being produced or used commercially in numerous countries around the world, including the United States, Austria, the Czech Republic, France, Germany, Italy, Malaysia, and Sweden. It is generally known that vegetable oils wer...

The U.S. Army Tank-Automotive Research, Development and Engineering Center (TARDEC) recently completed a Science and Technology Objective (STO) to develop and demonstrate a compact on-board smart sensor system for monitoring the operational condition of in-service diesel engine oils. The goal of such technologies is to reduce or eliminate the Army’s dependence on traditional oil analysis method...

Soil pollution by oil compounds is one of the most common environmental problems. To study the effect of four different treatments of soil diesel pollution and diesel degrading bacteria (control, diesel, one bacterium and three bacteria) on some growth and biochemical factors of two cultivars of Zea mays (704 and 640) a factorial research was undertaken in the form of a completely randomized de...

--Stringent emission norms and environment degradation due to pollutants from the automotive vehicles lead us to find the suitable alternative for the petro-diesel. Among the alternatives the non-edible vegetable oil seems to be most promising one. When the vegetable oil is used as fuel in diesel engine, it does not cause any major problem if used for a short period. However in the long run it ...

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...
