Abstract

Föreliggande uppfinning avser ett förfarande samt en anordning för att åstadkomma höga avgastemperaturer vid motordellaster i en dieselmotor, vilken motor innefattar åtminstone en cylinder med en fram och återgående kolv, har en varierbar kompressionsvolym (VCR), samt åtminstone en utloppsventil och åtminstone en inloppsventil, den senare med varierbara ventiltider (WT), varvid ett motorstyrsystem som utifrån aktuellt behov av motoreffekt beslutar när inloppsventilen skall öppna och stänga samt vilken storlek kompressionsvolymen skall intaga för att temperaturen i avgaserna vid evakuering skall vara erforderligt hög för befintlig avgasreningstekniks avsedda renande funktion.Förfarandet enligt uppfinningen kännetecknas av att trycket i avgaserna under arbetstakten av motorstyrsystemet styrs, via funktionerna för WT och VCR, så att vid en motordellast uppgående till 25%, eller mindre av maximal motorlast med hög motorverkningsgrad, nås eller underskrids rådande atmosfärstryck innan eller vid kolvens nedre vändläge.Anordningen enligt uppfinningen kännetecknas av att ett tryck i avgaserna under arbetstakten som regleras av ett motorstyrsystem, via funktionerna för WT och VCR, uppnås, varvid, vid en motordellast uppgående till 25%, eller mindre av maximal motorlast med hög motorverkningsgrad, nås eller underskrids rådande atmosfärstryck innan kolvens nedre vändläge.
