EN The attempts to increase the engine combustion efficiency of the spark ignition (SI) engines have led to development of the new combustion system with semi-open combustion chamber. This system is similar to flame jet ignition systems, which were applied in many production internal combustion engines. The similar pulsed jet combustion system was elaborated by Professor A. K. Oppenheim. In the system developed at Aircraft Engine Department of Warsaw University of Technology (AED) the standard combustion chamber of SI engine was divided on prechamber and main combustion chamber using partition. The ignition in prechamber is more reliable and repeatable but total burning time in the prechamber and main combustion chamber is shorter than in standard combustion chamber. The principal problem of efficient operation of this system and obtaining of the required performance is securing the relevant control strategy. The performances of this system are dependent from: the rate of this prechamber volume to total combustion chamber volume, the orifice diameter in a partition, the ignition place and the ignition advance angle (ignition timing). Among these parameters the ignition timing only may be varied in the continuous manner during the engine operations without of the engine disassembling. Therefore constant values separate parameters (prechamber volume, orifice diameter, ignition place) should be selected in comprehensive, time consuming researches for different engine operation conditions (engine speed, load and environment conditions) and subsequently the map of ignition advance angles should be determined at state remaining separate parameters. The values of the ignition advance angle should be selected and programmed in electronic control unit, which will be control the ignition advance angle at different engine operating conditions. The dependences between engine operating parameters and the ignition timing are not linear and therefore mechanical control system is not effective. Some research results concerning the best engine operating parameters has been presented in this paper.
