摘要

An air-fuel mixture arrangement for a combustion engine comprises: a stand (63) connectable to a cylinder head (4), a cover (65) closing said stand (63), a fuel injection valve (31); an intake pipe (22) mounted to said cover (65) and an air-fuel mixture valve (70) provided within said stand (63). Said air-fuel-mixture valve (70) comprises: an electromagnetic coil (73) a core (83) movable by a magnetic force of said electromagnetic coil (73), and a valve stem (81) movable by said core (83) in order to open said air-fuel mixture valve (70). Said cover (65) is provided with a through hole (65b) which constitutes an accumulator (21) receiving both fuel discharged by said fuel injection valve (31) and compressed air discharged by said intake pipe (22), said accumulator (21) being disposed in the vicinity of the upstream end of said valve stem (81).
