| Popis: | Publication devoted to the problem of translation of ship propulsion plant to low-sulfur fuel grades regulated by new International Maritime Organization (IMO) standards. Study and optimization of the physicochemical properties of marine fuels are important components in the work in order to improve energy efficiency and reduce toxic emissions from marine diesel engines. In the article gives the comparative analysis of standards of marine fuels. Using mathematical modeling, established variational indicated process characteristics of the diesel engine by simulating engine work in a wide range of fuels. As the object of the study was used diesel fuel, residual fuel, ethanol, RME and LNG. The aim of this work is to assess the impact of a number of properties of the fuel, in particular elemental chemical composition and calorific value to the energy performance of the working process of the diesel engine. Assessment carried out for the two cases of the diesel engine: the same cycle fuel delivery and implementations of the same indicated work, which is estimated at indicated pressure. The simulation results show that under the conditions of equal cyclic fuel supply differences indicated efficiency for different fuel are in the range 0.04–5%. |
