Abstract

Uppfinningen avser ett förfarande för att driva en förbränningsmotor med användande av vätskeformigt pilotbränsle, vilken motor (2) har flera cylindrar (3) och en motorstyrningsenhet (10) som är kapabel att vid onormal förbränning justera respektive cylinders förbränningstillstånd genom bränslereglering (100), bränsleavstängning medräknad. Vid onormal förbränning i en cylinder (3) hålls bränsleinsprutningen delvis aktiv med pilotbränsle som nämnda cylinders (3) pilotmunstycke (31) sprutar in (200).

Claims (3)

1. Förfarande för att driva en förbränningsmotor med användande av vätskeformigt pilotbränsle, vilken motor (2) harflera cylindrar (3) ooh en motorstyrningsenhet (10) som är 5 kapabel att vid onormal förbränning justera respektive cylinders förbränningstillständ genom bränslereglering (100), bränsleavstängning medräknad, kännetecknat av att man vid onormal förbränning i en cylinder (3) häller bränsleinsprutningen delvis aktiv med pilotbränsle som nämnda cylinders (3) pilotmunstycke (31) sprutar in (200).
2. Förfarande enligt patentkrav 1, kännetecknat av att man detekterar (110) 10 förbränningstillständet hos den cylinder pä vilken har utförts avstängning av huvudbränsle och jämför (130) det med ett förbränningsstillständ som man har förutbestämt för en av pilotmunstycket (31) insprutad bränslemängd.
3. Förfarande enligt patentkrav 1 eller 2, kännetecknat av att man ökar bränslemängden som sprutas in i den cylinder (3) pä vilken har utförts avstängning av 15 huvudbränsle. δ cv CNJ V 20 (M (M X cc CL I'-- co CO LO O δ (M
