Title (EN) DETERMINATION OF PRESSURIZED FUEL TEMPERATURE
(FR) DÉTERMINATION DE TEMPÉRATURE DE CARBURANT SOUS PRESSION
Abstract:
(EN) A method (300) and a system (200) for determining a temperature (Ttot) for pressurized fuel included in a high pressure fuel system (250) arranged for providing fuel to an engine (101) are presented. The method (300) includes determining a first temperature (T1)for a first fuel volume (V1) included in a first section (251) of the high pressure fuel system (250), where the first section (251) includes a common rail fuel system (253). The method (300) further includes determining a second temperature (T2) for a second fuel volume (V2) included in a second section (252) of the high pressure fuel system (250), where the second section (252) includes at least one fuel injector (271, 272, 273,..., 27n) arranged in a cylinder head (280) of the engine (101). The method (300) also includes the step of determining the temperature (Ttot) for the pressurized fuel based at least on the first temperature (T1) and on the second temperature (T2); Ttot=f(T1, T2).
(FR) L'invention concerne un procédé (300) et un système (200) de détermination d'une température (Ttot) d'un carburant sous pression présent dans un système de carburant à haute pression (250) agencé pour fournir du carburant à un moteur (101). Le procédé (300) consiste à déterminer une première température (T1) pour un premier volume de carburant (V1) présent dans une première section (251) du système de carburant à haute pression (250), la première section (251) contenant un système de carburant à rampe commune (253). Le procédé (300) consiste aussi à déterminer une deuxième température (T2) pour un deuxième volume de carburant (V2) présent dans une deuxième section (252) du système de carburant à haute pression (250), la deuxième section (252) comprenant au moins un injecteur de carburant (271, 272, 273,..., 27n) agencé dans une culasse (280) du moteur (101). Le procédé (300) consiste aussi à déterminer la température (Ttot) du carburant sous pression au moins en fonction de la première température (T1) et de la deuxième température (T2) ; Ttot = f(T1, T2).
