METHOD RESEARCH combustion process in internal combustion engines AND SYSTEM FOR CARRYING OUT

摘要

1. A method for the study of the combustion process in a combustion engine, comprising the steps of: registering supplying electric power to the spark plug, the time of appearance and disappearance of the ion current and the magnitude of each electrode ionisation sensor, characterized in that the comparison is carried out time of appearance and disappearance of the ion current each electrode showing the mean flow direction of the flame front, along a certain direction of movement of the flame front propagation speed is calculated and rear of the flame front in the main and final phases of combustion by dividing the distance from the spark plug to the corresponding electrode on the time interval from the current supply to the spark plug prior to the occurrence or extinction of the ion current in the respective isolated electrode or by dividing the distance between the insulated electrodes on the time interval between occurrences and disappearance of the ion current to the respective isolated electrode, respectively, the width of the combustion zone is determined by known races distances between the insulated electrodes and time intervals between the appearance and disappearance of the ion current to these electrodes, the intensity of the flow rates of chemical reactions of burning is determined amplitude of the ion current and the time of its existence in comparison with its amplitude and the time of existence of the ion current in the circuit corresponding to probe electrodes when burning fuel sostava.2 stoichiometric air mixture. Process for the investigation of combustion system in internal combustion engines comprising a cavity varies
