ABSTRACT
This study presents analyses concerning control processes of injection times of divided dose of fuel, startning from setting of injection time in controller up to moment of execution in compression ignition engine. Multiple injection doses were analyzed taking into consideration both sums of individual portions of doses as well as gaps between the doses. Studies were performed for various configurations of the doses, with different values of injection times and gaps between the injections. Measurements were performed for three measuring groups containing single-, two-, and five-portion doses. At constant values of time in a given group it have been applied variable injection pressures. The most important factors determining division of fuel dose were discussed.
