Internal combustion engine injected accumulation chamber
A description is given of an internal combustion engine having an intake passage and an exhaust passage, comprising: a cylinder block having a cylinder bore therein; a cylinder head mounted on said cylinder block and having a fixed-volume, non-cooled cavity therein; a piston reciprocally movable in said cylinder bore; a combustion chamber formed between said cylinder head and said piston, said cavity having a port connected to said combustion chamber; an intake valve movably mounted on said cylinder head for leading a suction gas from the intake passage into said combustion chamber; an exhaust valve movably mounted on said cylinder head for discharging an exhaust gas into the atmosphere; means for feeding fuel into said cavity to create a combustible mixture therein, said feeding means comprising a fuel injector; a spark plug having a spark gap located in said combustion chamber; valve means for opening said port of the cavity once per cycle during the compression stroke to spout out a jet of the combustible mixture under pressure into said combustion chamber from said cavity during the first half of the compression stroke and permit the inflow of the suction gas into said cavity from said combustion chamber during the latter half of the compression stroke for temporarily accumulting the suction gas under pressure after said port is closed; and a fuel injection control device for starting the injecting operation of said fuel injector immediately after said valve means is closed.
