This work was aimed at isolating and characterising biosurfactant producing bacteria strain from diesel oil contamination sites. The potential of the to degrade n-alkanes further studied. Soil samples were collected rich areas, identified strains grown on minimal media that contained as only carbon source. Enrichment culture technique used identify bacteria. Seventeen based their capacity use O...

BACKGROUND Particulate pollution is associated with the occurrence of asthma and allergy. The model pollutant, diesel exhaust particles, can participate with allergens in starting and exacerbating allergic airway diseases in part by production of reactive oxygen species. Glutathione-S-transferases (GSTs) can metabolise reactive oxygen species and detoxify xenobiotics present in diesel exhaust p...

An innovative concept called “Flexy developing at 2iE. This concept aims to produce electricity cost by smartly mix different available energy to the load profile of the region. With a higher solar irradiation and due to the fact that Diesel generator are massively used in sub Saharan rural areas, PV/Diesel hybrid syste application of this concept and a good solution to electrify this region, p...

The main objective of the research is to compare the accurateness of Artificial Neural Networks (ANN) and Multiple Linear Regressions (MLR) model for Specific Fuel Consumption for pyrolysis oil blended with diesel used in a single cylinder diesel engine. In this study, parameters i. e. Injection Timing, Injection Pressure, Compression Ratio, and Load are taken. Artificial Neural Networks (ANN) ...

A large number of non-stationary dynamic signals are generated in the working machinery and equipment. Especially, diesel engines often encounter non-stationary transient and time-varying modulation signals, such as the impulse response signals caused by cylinder piston wear. These kinds of signals generated from diesel engine are analyzed by the method of the Local Wave time-frequency proposed...

The combination of the remote-area-diesel generators with a battery storage and renewable energy source such as photovoltaic (PV) can greatly overcome the problems of these generators. In this paper a PV/Diesel generator hybrid energy system is sized to meet the load for about 100% availability. Where, for a given load characteristic and a given diesel generator a methodology is developed to op...

● Diesel Filter Regeneration Abstract: Diesel particulate filters capture particle emissions through a combination of surface-type and deep-bed filtration mechanisms, such as diffusional deposition, inertial d positi , or flow-line interception. Collected particulates are removed from the filter, continuously or periodically, through thermal regeneration. Diesel filters are very effective in co...

In this paper, the control scheme of a Liquefied Petroleum Gas (LPG)–diesel dual-fuel engine with electronic control is illustrated, the external characteristics and load characteristics of the LPG– diesel dual-fuel engine and the diesel engine are compared and analyzed. The experimental results show that, compared with diesel, the output performance of dual fuel is not reduced, while smoke emi...

background : studies show that there is association between air pollution and disturbances on normal function of various systems of body. the main aim of this study was to determine the effects of diesel oil vapor inhalation on serum creatine, alkaline phosphatase, sgot and sgpt levels as indices of liver function in male rats. methods: thirty two rats were randomly divided into 4 groups: contr...
