Abstract (en)
[origin: DE19628739A1] The invention concerns a method of controlling the injection process in a high-speed 2-stroke internal combustion engine (11). According to the invention, the internal combustion engine (11) comprises first means (12) for generating one trigger signal per revolution, said signal being fixed with the angle of rotation, for controlling injection, and second means (13) for generating alternating voltage which is dependent on the speed of rotation and whose period is a fraction (1/n) of the time per revolution (revolution time) of the 2-stroke internal combustion engine (11). A simple electronic injection-control arrangement having optimum injection parameters which can be calculated precisely for all speeds of rotation is attained in that, in addition to the trigger signal, the alternating voltage generated is additionally used to control the injection process.
