Abstract:
Method, system, and computer program product are provided for determining pressure in a fuel accumulator tank of a multi cylinder internal combustion engine during operation. Pressurized fuel is distributed from said accumulator tank to the cylinders by fuel injectors. A pump unit provides pressurized fuel to said accumulator tank by pump actions comprising pump strokes. The method comprises: performing pressure sampling of pressure in the fuel accumulator tank based upon a relationship between the number of pump strokes and a number of injections per crank shaft revolution such that pressure sampling occurs in connection to a fuel injection where the mutual relationship between that fuel injection and the pump action reoccurs at the fuel injection for which a pressure is to be determined; and determining a pressure in the fuel accumulator tank based upon the pressure sampling in connection to at least one earlier fuel injection, for controlling fuel injection to an individual cylinder.

Claim (Index 12):
A system according to  claim 7  comprising:\n means for determining engine operation status, wherein the means for performing pressure sampling based upon the relationship between the number of pump strokes and the number of injections per crank shaft revolution is arranged to be performed under steady state engine operation; and \n means for changing a performance of pressure sampling such that pressure sampling is performed at a fuel injection or fuel injections closest to the fuel injection for which the determined pressure is intended to form a basis if the engine operation changes from steady state engine operation to operation involving rapid changes of pressure in the fuel accumulator tank.
