摘要： The invention relates to a driving device for a lawn trimmer, comprising a two-stroke engine having an injection valve (12), a clutch (15), devices for aspirating and releasing air (17, 20, 22), and a fuel pump (18), as well as possible additional component sets. The invention aims to create a compact structure and ensure functional reliability by cooling the fuel and guiding the air in a targeted manner. To this end, the injection valve (12) is mounted on the clutch side in such a way that the jet is directed in the direction of the spark plug (11).

摘要： The invention relates to a driving device for a motor scythe, comprising a two-stroke engine having an injection valve (12), a coupling placed in a coupling housing (15), air intake and air exit devices, a fuel pump (17), a starter housing (18) and possibly additional devices and equipment. In order to achieve a compact arrangement of the parts of the cited driving device with optimal cooling and combustion, the invention provides that the coupling housing (15) and the starter housing (18) be placed on opposite lying sides of the two-stroke engine and that the injection valve (12) with its injection nozzle be oriented towards the cylinder head or the spark plug (11).
