Definitions

  • the present invention relates to an internal combustion engine comprising at least one cylinder associated with a fuel air injection compressor under pressure in the combustion chamber of this cylinder.
  • motors of this type in which the compressor is adapted to draw carburetted air through a suction pipe fitted with a first shutter and for discharging carburetted air under pressure in the combustion chamber through a discharge pipe fitted with a second shutter.
  • the object of the invention is therefore to solve these problems.
  • the invention relates to an internal combustion engine of the two-stroke and scanning type comprising at least one cylinder associated with an air injection compressor fuel under pressure in the combustion chamber of this cylinder, this compressor being adapted for sucking fuel air through a suction pipe fitted with a first shutter and to discharge pressurized carburetted air into the combustion chamber through a discharge pipe fitted with a second shutter, characterized in that the suction duct and the discharge duct are formed in a cylinder head arranged on a cylinder block of the engine in which the cylinder and the compressor are arranged side by side and in this at least the second shutter is formed by a blade valve detachably attached to a support piece removably engaged in a cylinder head well in the path of the conduit discharge between the compressor and the combustion chamber, to facilitate maintenance of this valve.
  • This engine comprises at least one cylinder designated by the reference general 2, associated with a compressed air injection compressor 3 in the combustion chamber 4 of this cylinder.
  • Compressor 3 is suitable for vacuuming from everything suitable supply device (not shown), fuel air through a suction duct designated by general reference 6, provided with a first shutter, designated by the general reference 7, and to discharge fuel air under pressure in the combustion chamber 4, through a discharge pipe, designated by the general reference 8, provided with a second shutter designated by the general reference 9.
  • the discharge conduit 8 is formed in a cylinder head designated by the general reference 10, arranged on a cylinder block 11 of this engine and the second shutter designated by the general reference 9, is formed by a reed valve carried by a support piece designated by the reference general 12, engaged in a well designated by the general reference 13 of the cylinder head 10, in the path of the discharge conduit between the compressor 3 and the combustion chamber 4.
  • the suction duct 6 is also provided for example in the cylinder head 10 of this engine.
  • cylinder 2 and the compressor 3 are arranged side by side in the engine cylinder block and the first shutter designated by the general reference 7, can be formed by a valve integral with a cylinder head gasket designated by the general reference 14 in this figure, interposed between the cylinder head 10 and the cylinder block 11 of the engine.
  • the support part 13 of the reed valve 9 is fixed so removable in the cylinder head well designated by the general reference 13.
  • This fixing can for example be ensured by screwing means materialized by mixed lines designated by the general reference 15 on this figure.
  • An O-ring designated by the general reference 16 can be provided between this support piece and the rest of the cylinder head to ensure a seal between these organs.
  • the reed valve designated by the general reference 9 which can have any suitable structure, can also be fixed from removable way on the support piece 12.
  • the fixing of this reed valve on the part can by example be provided by screwing means designated by the general reference 17 in this figure, associated with a clamping piece 18 of the valve on the rest of the support piece.
  • the support piece has abutment surfaces, for example 19 and 20, delimiting the opening and closing positions of the reed valve, the valve moving between these surfaces according to the pressures on both sides of it.
  • the delivery duct designated by the reference 8 opens into the combustion chamber 4 of the cylinder at level of a combustion stratification bowl designated by the general reference 21 in this figure and which is preferably provided in the cylinder head 10.
  • the first shutter 7 closes, while the second shutter constituted by the reed valve 9, opens due to pressure in this compressor, to allow injection of pressurized carburetted air in the combustion chamber of the cylinder.
