The behavior of single drops of two- and three-component mineral diesel fuel blends with ethanol and rapeseed oil methyl ester in a heated atmosphere has been investigated. With the use of the known quasi-stationary approach, the influence of the thermal properties of fuel blend components and their composition on the ignition delay time of the drop has been investigated. It has been established that under inert heating conditions of the drop, additions of low-boiling ethanol to diesel fuel should shorten the duration of the preignition period, and additions of rapeseed oil methyl ester should, on the contrary, prolong it. Analysis of the obtained data has made it possible to determine the optimal composition of the fuel blend for the most economical operation of the diesel. The prognostic estimates made are confirmed by laboratory experiments and bench tests of fuel blends....
Transport activity has been a key facilitator and driver of economic prosperity in Lithuanian (hereinafter LIT) and it is likely to continue to grow. It can produce both positive and negative effects on the quality of life and the environment depending on country-specific circumstances.This research paper sets the stage for a look at the LIT passenger vehicle fleet and its transition towards sustainable...
The effect of dehydrated ethanol and rapeseed methyl ester additives to diesel fuel on engine fuel consumption has been experimentally investigated. The used average capacity (18 kW) tractor was driven by unmodified direct injection (combustion chamber consists of a dished piston) four cylinder, two-cycle diesel engine D21A1. Multicomponent fuel blends were prepared by adding 5 and 10% (v/v) of ethanol...
W artykule przedstawiono wyniki badań pracy ciągników rolniczych o mocy 18 i 58 kW (T-25A i MTZ-82) przy zasilaniu paliwem biodiesel (rapso-metylowym esterem RME) i różnymi jego mieszankami z olejem napędowym. Ustalono zużycie czasowe i względne (g/kWh) przy przygotowaniu gleby do siewu z kombinowanym agregatem przy różnych obciążeniach ciągnika i różnych mieszankach paliwowych. Przy pracy ciągnika...
