A fuel-supply system using movable fuel-supply vehicles (FSVs) is proposed and its performance is evaluated. Both FSVs and vehicles requesting fuel are equipped with networked sensors. The sensors in FSVs are location sensors, and those in vehicles requesting fuel are for determining the remaining amount of fuel and the location of the vehicle. The time from when a fuel request is generated unt...

Recently, the world is facing energy crisis for non-renewable resources. So people are searching for high efficient energy transformations and way to utilize the alternate energy sources. Fuel cells are an important part in the research. The main aspects of fuel cell research is to reduce the cost and simplifying implementation conditions In recent years, people are moving towards microbiology ...

Microbial fuel cells (MFC) are a promising technology for sustainable production of alternative energy and waste treatment. A microbial fuel cell transformation chemical energy in the chemical bonds in organic compounds to electrical energy through catalytic reactions of microorganisms under anaerobic conditions. It has been known for many years that it is possible to generate electricity direc...

The design and development of modern internal combustion engines is marked by a reduction in exhaust gas emissions and increase in specific power and torque. This paper aims at the study of noise reductuion in4-stroke common rail direct injection engine at idle speed. Idle speed is basically a speed of engine when vehicle is not running i.e not in motion . Now a days , this siuation oftenly com...

In this review a brief description is given for the biofuel cells along with their classification. The review is mainly intended to concentrate on microbial fuel cells (MFCs) where micro-organisms are used to convert the fuel to electrical energy and also this review gives an overview of the advances made in the past two years in MFCs in terms of their research, development and performance. Som...

The objective of the work was investigation of possibility of dual fuelling of CI engine with diesel fuel and ethyl alcohol in order to decrease engine emission and increase its thermal efficiency. Alcohol, which is injected to the engine inlet port evaporates quickly, but doesn't ignite (due to low cetane number). After self-ignition of diesel fuel, ignited alcohol would promote further burnin...

A tailored model for the assessment of environmental benefits achievable by light-weighting design solutions in the automotive field is presented. The model is based on the Fuel Reduction Value (FRV) coefficient which expresses the Fuel Consumption (FC) saving involved by a 100 kg vehicle mass reduction. The work is composed by two main sections: simulation and environmental modelling. Simulati...

Renewable energy is an increasing need in our society. Microbial fuel cells (MFCs) represent a new method for treating wastewater and simultaneously producing electricity. In the present study, we demonstrated the feasibility of bioelectricity generation from brewery wastewater treatment using a mediator less MFC at different pH. We also demonstrated that addition of readily utilizable substrat...
