Summary:

Dual fuel engines have shown the potential to extend the operating range of homogeneous charge compresion ignition (HCCI) by using several combustion modes, such as Reactivity charge compresion ignition (RCCI) at low load, and partially premixed compresion igniton (PPCI) at high load. The detection and diagnosis of the combustion sensitivity to each input is critical for the control system.This paper presents a new technique for combustion mode detection in a dual fuel engine which has been operated in dual fuel mode: fully, highly and partially premixed. The gasoline fraction and the start of the injections have been used as critical inputs for the combustion phasing and a extremum techniques were used to optmize the CA50 and to detect the level of stratification
