Method for controlling an injection valve in a high-speed 2-stroke internal combustion engine with fuel injection and device for carrying out the method

摘要

In a process for controlling an injection valve (16) in a fast-running fuel-injection two-stroke internal combustion engine, in which a trigger signal is generated at each revolution of the engine at a triggering point (TP1, TP2) and the injection process is actuated in accordance with the trigger signal, where at low revolution speeds the start of injection is in a first region (ESB1) of the angle of rotation of the crankshaft and at higher revolution speeds the start of injection lies in a second region (ESB2) of said angle of rotation, where said second region (ESB2) is displaced in the "advance" direction towards the top dead centre (OT) in relation to the first region (ESB1), the best possible operation is attained in that a special triggering point (TP1 or TP2) is allocated to each of the two regions (ESB1 or ESB2) and, on a transition from low to high revolution speeds the control is switched over between the two triggering points (TP1, TP2) from a predetermined threshold speed.
