A METHOD OF DETERMINING IN REAL TIME THE FLOW RATE CHARACTERISTIC OF A FUEL INJECTOR

摘要

pThe method involves replacing a reference fuel injection by multiple injections that inject same quantity of fuel as that of the reference injection. An error of flow characteristic is deduced from a difference of the fuel quantities injected by two injections. Gain/offset of linear zone or a table/mathematical relation of non linear zone of the characteristic are modified to compensate the error./p [FR2857700A1]
