Method of controlling the operation of an internal combustion engine of the two-stroke cycle and direct fuel injection type and internal combustion engine

摘要

A method of controlling the operation of an internal combustion engine of the two-stroke cycle and direct fuel injection type, wherein at least in a low load range below a predetermined first load boundary fuel is intermittently or once in a plural number of cycles, respectively, injected, and wherein in a high load range above said first load boundary fuel is injected in every cycle, at least in the vicinity below said first load boundary the amount of the injected fuel per injection cycle is larger than the amount of injected fuel per cycle in the vicinity but above said first load boundary. <IMAGE>
