Performance and emission characteristics of diesel engines running on gaseous fuels in dual-fuel mode
PublikacjaConventional fossil fuels are being substituted with alternative green fuels because of their greenhouse gas emissions and pollution problems, which pose a severe threat to the environment. Several studies have reported the usage of biodiesel and gaseous fuels in both single and dual-fuel modes. Gaseous fuels such as producer gas, biogas, syngas, and hydrogen produced from renewable biomass could potentially be used along with...

Evaluation of energy efficiency of vehicles powered by different fuels
PublikacjaW pracy przedstawiono nową metodę oceny efektywności energetycznej pojazdów zasilanych różnymi paliwami. Analizę można wykonać na podstawie jednego przejazdu w regularnym ruchu miejskim z rejestracją podstawowych parametrów silnika i pojazdu. Warunki eksploatacji identyfikowane są przy użyciu energochłonności jednostkowej, która uwzględnia zarówno wpływ warunków zewnętrznych jak również styl jazdy kierowcy.

Comparison of energy efficiency of vehicles powered by different fuels
PublikacjaNajpopularniejsza metoda oceny efektywności energetycznej pojazdów samochodowych polega na porównywaniu przebiegowego zużycia paliwa osiągniętego w warunkach wybranego testu homologacyjnego. Warunki eksploatacji, zdefiniowane za pomocą przebiegów prędkości w czasie, dotyczą najczęściej tylko dwóch kategorii: jazdy miejskiej i pozamiejskiej. Problemy wynikające z takiego sposobu postępowania zostały omówione na przykładzie analizy...

Algorithms of chemicals detection using raman spectra
PublikacjaRaman spectrometers are devices which enable fast and non-contact identification of examined chemicals. These devices utilize the Raman phenomenon to identify unknown and often illicit chemicals (e.g. drugs, explosives)without the necessity of their preparation. Now, Raman devices can be portable and therefore can be more widely used to improve security at public places. Unfortunately, Raman spectra measurements is a challenge...

Method of evaluation of lubricating ability of lube oils and fuels in energetistic formulation
PublikacjaThe paper presents an interpretation of operation of a boundary layer of a lubricating medium. A model of the homogeneous Poisson process has been proposed to assess the deterioration process of the layer's operation. The assessment considers the original interpretation of operation of a boundary layer, as a lubricity measure of a boundary layer of any lubricant. In the submitted proposal the operation of a boundary layer is understood...
