Abstract

The paper presents examination results of engine AD3.152 fuelled with hydrocarbon fuel Ekodiesel Plus 50B and vegetable fuel EMKOR enabling to determine fuel pressure increase in injection pipe and characteristics of heat emission during combustion process. Analysis of experimentally obtained diagrams of fuel pressure in injection pipe enables to determine fuel pressure increase rate. Characteristics of heat emission during combustion process were determined based on of experimentally obtained indicator diagrams. The realization of latest norms of concerning issues of toxic components of combustion gases constrains the user of diesel engines the possession of quick and precise estimation methods. On the ground comparisons of test results received at supply of the engine with two ecological fuels i.e. low-sulphur of the derv Ekodiesel 50B Plus and the vegetable fuel - the methyl ester of acids of the rapeseed oil EMKOR were formulated conclusions.
