Abstract
When a two-stroke combustion engine (10) runs in the no-load or underload mode with intermittent fuel injection, besides the injection nozzles (12) being activated intermittently, the throttle (18) is opened more than is usual on transition into the no-load or underload mode and the fuel is simultaneously injected at a constant angle of aperture and flow. The process ensures reliable ignition of a weak mixture in the no-load or coasting mode; thus the energy consumption and exhaust production are limited in these modes and the engine runs in a cost-effective manner.
