PCT No. PCT/EP97/01316 Sec. 371 Date Sep. 2, 1998 Sec. 102(e) Date Sep. 2, 1998 PCT Filed Mar. 17, 1997 PCT Pub. No. WO97/36098 PCT Pub. Date Oct. 2, 1997In a method for controlling an injection valve (16) in a high-speed internal combustion engine with fuel injection, in which method, with each revolution of the engine, at a trigger point (TP1,TP2), a trigger signal is generated and according to the trigger signal, the injection operation is initiated, in which, for low engine speeds, the injection start is within a first range (ESB1) of the crankshaft angle of rotation and in which, for high engine speeds, the injection start is within a second range (ESB2) of the crankshaft angle of rotation, which second range (ESB2) in comparison with the first range (ESB1), is displaced in the direction "early" relative to the top dead center (OT), an optimal operating behavior is achieved in that, to each of the two ranges (ESB1 or ESB2), a trigger point of its own (TP1 or TP2) is allocated and in that, when changing between low and high engine speeds, starting from a predetermined threshold engine speed, a changeover of the control between the two trigger points (TP1,TP2) takes place.
