Landfill leachate emerges as a promising feedstock for microbial fuel cells (MFCs). In the present investigation, direct airbreathing cathode-based MFCs are fabricated to investigate the potential of landfill leachate. Three MFCs that have different cathode areas are fabricated and investigated for 17 days under open circuit conditions. The maximum open circuit voltage (OCV) is observed to be a...
The purpose of this study is to determine the optimum intake valve closing time of a large diesel engine having lower fuel consumption and lower NOx emission. The performance simulation has been conducted for this purpose, and a phenomenological combustion model is verified by experimental data of heat release rate and NOx emission in order to enhance the prediction quality of the performance s...
We present an industrial case study in automotive control of significant complexity: the new common rail fuel injection system for Diesel engines, currently under production by Magneti Marelli Powertrain. In this system, a flow–rate valve, introduced before the High Pressure (HP) pump, regulates the fuel flow that supplies the common rail according to the engine operating point. The standard ap...
Most bacteria known to be electrochemically active have been harvested in the anodic compartments of microbial fuel cells (MFCs) and are able to use electrodes as electron acceptors. The reverse phenomenon, i.e. using solid electrodes as electron donors, is not so widely studied. To our knowledge, most of the electrochemically active bacteria are Gram-negative. The present study implements a tr...
Experimentation about alternative fuels started mostly after the oil crisis of 1980’s to 1990’s after the World War II. In order to reduce the use of petroleum product which are limited in nature, the idea of alternative fuels was developed. In this paper an attempt has been made to investigate the engine performance in a four stroke single cylinder water cooled diesel engine using pure diesel ...
Microbial fuel cells hold great promise as a sustainable biotechnological solution to future energy needs. Current efforts to improve the efficiency of such fuel cells are limited by the lack of knowledge about the microbial ecology of these systems. The purposes of this study were (i) to elucidate whether a bacterial community, either suspended or attached to an electrode, can evolve in a micr...
In Microbial Fuel Cells (MFCs), a mass transfer impact might be larger than expected because it not only effects the mass transfer losses (substrate flux [1, 2] and removal of waste [2]), but also effects the activation losses (mediator [3-5]) and the ohmic losses (proton transfer [6]). However, the convection/diffusion of the reactant transport from the bulk (reactant transport), which can be ...
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...
At the previous conference KONES’2004 emission characteristics of C.I. engine fuelled with either rape oil methyl ester (RME) or diesel fuel (DF) as a main fuel and ethanol as additional fuel were presented. Comparison of emission and brake fuel conversion efficiency (BFCF) of the engine fuelled with both main fuels showed that fuelling with RME and ethanol is more advantageous on account of bo...
A variety of microsystems have been developed that harness energy and convert it to mechanical motion. Here we have developed new autonomous biochemical motors by integrating a metal-organic framework (MOF) and self-assembling peptides. The MOF is applied as an energy-storing cell that assembles peptides inside nanoscale pores of the coordination framework. The nature of peptides enables their ...
