Microbial fuel cells (MFCs) represent a completely new long term, affordable, accessible and ecofriendly approach to waste water treatment with production of sustainable energy. The power generation efficiency in microbial fuel cells (MFCs) is based on bioreactors, which may represent a completely new approach to wastewater treatment. In our experimental test we found that it is possible to gen...

Several technologies are being used in distributed generation applications with variable degree of success. Among those are: wind turbines, small-scale hydropower plants, biomass, microturbines, photovoltaic arrays and fuel cells. In a fuel cell, the chemical energy incorporated in the fuel is converted directly to electricity and heat. Fuel cell technology is one of the most interesting energy...

This report examines the possible safety benefits from driving in a manner that results in lower fuel consumption and emissions. It attempts to assess the potential of promoting additional motivations to drive safely – better fuel economy and other environmental outcomes, and reduced running costs. Reducing speeding, lower speed limits and modifying driving style were found to improve fuel econ...

Respiratory Diseases are public health concern worldwide. The diseases have been associated with air pollution especially indoor air pollution from biomass fuel burning in developing countries. However, researches on pollution levels and on association of respiratory diseases with biomass fuel pollution are limited. A study was therefore undertaken to characterize the levels of pollutants in bi...

Stringent CAFÉ regulations along with technological advances in materials, high-pressure fuel injection and complex turbo charging systems have rekindled interest in the area of Diesel engines for passenger vehicle applications. A modern Diesel engine is not only clean and quiet but also allows comparable drivability relative to gasoline engines with considerable improvements in fuel economy. H...

In this study, the effect of second injection timing on the combustion and emissions characteristics of a direct injection HCCI gasoline engine was investigated by using ethanol and methanol blended gasoline fuel. For this aim, a diesel engine was converted to an electronically controlled HCCI gasoline engine. The injection timings and fuel quantity for each injection were adjusted to get desir...

The consumption of oil fuel in Java shows that more than 70% of oil fuel is consumed in metropolitan cities, 14.2% is consumed in big cities, and 15.67% is consumed in medium cities. The variables of urban transport system powerfully influencing on oil fuel consumption are motor vehicles and roads. The influence of city typology (the number of population and) on oil fuel consumption is greater ...

A computer controlled direct gasoline fuel injection (DGI) system has been modeled, programmed and constructed for a four-stroke SI engine. Locally available materials have been used for this experimental model. All the old model vehicle were equipped with carburetor for air fuel mixing and later on electronic fuel injection system has been introduced for maintaining better air fuel ratio and m...

An accurate fuel injection advance angle is an important parameter to obtain better fuel combustion index and emission index. Fuel injection advance angle is always deranged because of the wear of the injection nozzle matching parts, which has serious impact on diesel engine performance. How to measure the fuel injection advance angle easily and accurately is a problem for fault diagnosis of hi...
