The necessity for decrease in consumption of conventional fuel, related energy and to promote the use of renewable sources such as biofuels, demands for the effective evaluation of the performance of engines based on laws of thermodynamics. Energy, exergy, entropy generation, mean gas temperature and exhaust gas temperature analysis of CI engine using diesel and karanja methyl ester blends at d...

This article presents the development of electric turbofan engine in distributed architecture with a design thrust range 3 to 7.5 and from 30 kN for small medium-sized unmanned aerial vehicles. The subsystems are considered as separate smart modules built-in control system, exchanging data via digital channel central diagnostics unit. key units combined following subsystems: starter turbine gen...

Landfill gas (LFG) that is generated in an anaerobic environment in landfills and consists primarily of methane and carbondioxide with small amount of nitrogen and other non-methane gases, could be collected and used to produce energy either by extracting methane or using the landfill gas directly in an internal combustion engine or a gas turbine. It amounts to be a net-negative greenhouse gas ...

The influences of different diesel/biodiesel blends and EGR rate on brake specific fuel consumption (BSFC), exhaust gas temperature, NO, HC, CO emissions, are studied and demonstrated. In this paper a four stroke direct injection, water cooled, diesel engine was used. Biodiesel either in neat form or as a blend with diesel fuel is extensively investigated to solve the twin problem of reduction ...

Exhaust gases from an internal combustion engine, alternatively powered by gasoline or by liquefied petroleum gas, were analysed for polynuclear aromatic hydrocarbons. The engine operated a lift truck for the handling of warehouse goods. A combined condensation-filtration apparatus was constructed for sampling of the exhausts. The basic steps of the analytical procedure are summarized here. Sev...

This paper considers the problem of selecting a set of residual generators, fulfilling requirements in terms of fault isolability and minimal cardinality, for inclusion in a model-based FDI-system. Two novel algorithms for solving the selection problem are proposed. The first one provides an exact solution fulfilling both requirements and is suitable for small problems. The second one, which is...
