Electric current characteristics of the injector generating fuel doses

Abstract: In this article, the proposal for modelling the gas (fuel) injector based on observations of changes in the current during operation of the needle is presented. The aim of this work is indicating that the dosage characteristics can be mapped by means of the current characteristics. Moreover, observation of the current allows for determining the actual position of the needle. The time of the real fuel flow and the injector phase position can be determined with a microsecond resolution. The injector core inducta… Show more

“…One of the important directions of research on their development is the elaboration of systems for automatic diagnosing of the condition of actuator valves as components that have a significant impact on the operation of engines, fuel consumption, and emissions of toxic exhaust components. The authors’ previous research into analyzing current signals of internal combustion engines [ 2 , 8 , 32 , 33 ], especially fuel injectors, has led to a conclusion that in the considered case of injector research, there is an unambiguous lack of software of this type for analyzing the current values of injectors in an automatic manner during their operation on the engine. The development of these systems may contribute to the emergence/expansion of self-adjustment or adaptive systems relative to their momentary technical condition in the future.…”

“…The development of these systems may contribute to the emergence/expansion of self-adjustment or adaptive systems relative to their momentary technical condition in the future. The authors are working on developing and implementing the research methods [ 2 , 8 , 32 , 33 ] established in the past. The direction of current work is primarily the development of software for its implementation in the ECU.…”
