Vorrichtung zur Überwachung der Betriebsumstände eines fremdgezündeten Verbrennungsmotors

摘要

A method for surveying the operating conditions of an internal combustion engine with spark ignition, wherein in one and the same engine cycle a plurality of primary charging cycle are generated which produce corresponding secondary discharge cycles. The pressure pattern in the combustion chamber is determined, in each period of time, as the product of the maximum intensity of the induced primary voltage (V1i) by the respective duration (ti).
