Title: (EN) DETERMINATION OF PRESSURIZED FUEL TEMPERATURE
Abstract: front page image
(EN)

A method and a system for determining a temperature for pressurized fuel included in a high pressure fuel system arranged for providing fuel to an engine are presented. The method includes determining a first temperature for a first fuel volume included in a first section of the high pressure fuel system, where the first section includes a common rail fuel system. The method further includes determining a second temperature for a second fuel volume included in a second section of the high pressure fuel system, where the second section includes at least one fuel injector arranged in a cylinder head of the engine. The method also includes the step of determining the temperature for the pressurized fuel based at least on the first temperature and on the second temperature.
