This patent describes a multiple-cylinder, two-stroke, fuel-injected internal combustion engine, means for operating the engine at idle means for interrupting the fuel injection stages in a predetermined pattern such that over a certain number of engine crankshaft revolutions a fewer number of injection states occur than over the same number of engine crankshaft revolutions during non-idle operation, and means for increasing the quantity of fuel injected per injection stage relative to the quantity of fuel required per injection stage to secure idle operation without any injection interruption.
