Abstract
A fuel injection system for a two-stroke internal combustion engine (1), elastically housed internally of a chamber, comprises a carburetor (30) to which are associated an induction port (9) for an air/fuel mixture and a fuel supply conduit (10) intercepted by means for metering housed in a recess (16) communicating with a second aperture (15) located above the induction port (9), which is in turn connected by an accumulation conduit (12) to a first aperture (14) located below the induction port (9), the apertures (14, 15) being alternatively opened by the piston skirt (3); the accumulation conduit is entirely afforded in the cylinder body.
Claims8
A fuel injection system comprising an accumulation conduit (12) of fuel, which accumulation conduit (12) communicates with a first aperture (14) located below an induction port (9) and with a second aperture (15), located above the induction port (9), the apertures (14, 15) being characterised in that the accumulation conduit is entirely contained in the cylinder body.
