As a part of the research work done on the engine URSUS 4390 which aimed at increasing power while reducing exhaust gas emissions, intake channels in the head, shape of the combustion chamber and compression ratio were modified. Proper injection equipment was selected and atomizer nozzles were constructed. In the first phase of the research, toroidal combustion chamber was located in factory design location. In the article there are presented results of exhaust gas emissions in selected operating points of engine URSUS 4390 for various positions of experimental combustion chamber. An innovative method of changing the position of the combustion chamber related to the piston axis was developed. A rotating insert with eccentrically extruded combustion chamber was mounted in piston axis. Rotation of the insert by a given angle resulted in displacement of combustion chamber around the axis of rotation. For each particular position of combustion chamber, concentration of toxic flue gas components and smoke index was measured at full load with rotational speed of 1400 and 2000 rpm. Proposed piston construction with rotating insert allowed to significantly decreasing duration of the research, which aimed at verification of combustion chamber relative location to injector and inlet nozzle. This way the necessity of construction of new sets of pistons and lapping them each time was avoided. As a result of the work, 11 locations of combustion chamber were tested. The study allowed picking the position of combustion chamber, which guarantees lowest emissions of toxic flue gas components.
