The diesel and the vegetable oil properties assessment in terms of pumping capability and cooperation with internal combustion engine fuelling system

Abstract

In the paper, the results of preliminary diesel and vegetable oil research were shown, the subject of which were directly intended to be the fuel for powering compression ignition engines. In the times of climate protection and more strict standards concerning combus-tion gas emissions, the fuel production and transportation process became an important aspect. Decentralization of this process and ena-bling fuel obtaining directly from cultivation (oleaginous plants) let limit the global CO2 emission. This is why the preliminary assessment of two fuel sorts properties was attempted, on one side, the basic one, which is the diesel, on the other side - vegetable oil. Prior to sub-jecting the compression ignition engine to the process of adaptation to vegetable fuelling, the properties of the fuel responsible for pumping should be assessed (mainly viscosity) and friction nodes cooperation (lubricity). The first of researched parameters is the base to elaborat-ing the system of engine controlling algorithm or the range of changes in construction of powering system. The second one is the wear is-sue - object fitness and repairing overhauls.
