A fuel injection system in which only one pump element at a time can aspirate fuel. As a result, it is attained that even in partial-load operation, all the pump elements are in operation, and as a consequence the smooth operation of the engine in partial-load operation is improved.

High-pressure fuel pump for internal combustion engine with improved partial-load performance

The present invention relates to a system for determining axial displacement of a rod forming part of a device comprising a member in which are formed at least two chambers containing high-pressure fluid and each defined by a respective surface portion of the rod. The system consists in forming a sliding coupling between the rod portion separating the two chambers and the seat in which the rod slides; in forming, on the aforementioned rod portion, a pair of annular grooves defining an annular surface portion; in forming at least a housing on the aforementioned member; and in fitting inside the housing a proximity transducer for determining displacement of the annular surface portion parallel to the rod.
