Definitions

  • the present invention relates to an internal combustion engine of the type comprising at least one cylinder head with several aligned cylinders and an air intake device comprising a distribution box for the intake air to which an air tube is connected and at least one intake duct, the outlet of which is connected to an intake manifold formed in the cylinder head.
  • the object of the invention is to propose a design of the upper part of the engine which makes it possible to solve the problems of space and internal arrangements of the engine compartment which have just been mentioned.
  • the invention provides an engine of the type mentioned above, characterized in that it comprises a cylinder head cover mounted on the upper face of the cylinder head and which comprises partitions which divide the internal cavity into compartments to constitute the at least partially the intake device.
  • the engine 10 essentially consists of a cylinder block 12 surmounted by a cylinder head 14 covered by a cylinder head cover 16.
  • the cylinder head is supplied with intake air by an intake device 20 comprising an air distribution unit 22 to which are connected an inlet tube 24 equipped with a throttle valve 26 and tubular conduits of suction 28, the outputs of which are connected to the intake pipes (not shown) formed in the cylinder head 14.
  • an intake device 20 comprising an air distribution unit 22 to which are connected an inlet tube 24 equipped with a throttle valve 26 and tubular conduits of suction 28, the outputs of which are connected to the intake pipes (not shown) formed in the cylinder head 14.
  • FIGS. 1 and 2 also recognize the fuel injectors 30 and an air filter 32.
  • the cylinder head cover 16 has the function only of closing the upper face of the cylinder head while protecting the rotating moving parts such as the camshafts and / or rocker linkages.
  • Each cylinder is connected to the air intake device by three intake valves and to the exhaust by two exhaust valves.
  • the two intake valves 34 are controlled by a first camshaft 40 while the intake valve 36 and the two exhaust valves 38 are controlled by a second camshaft 42.
  • the axes of rotation of the camshafts 40 and 42 are parallel to the line of the cylinder heads of the cylinder head.
  • the cylinder head 14 has a lower face 44 designed to cooperate with the upper face of the cylinder block 12 with the interposition of a cylinder head gasket, the combustion chamber 46 of each cylinder being formed at least partially in this lower face 44.
  • the cylinder head 14 has a flat upper face 48 parallel to the lower face 44 which cooperates with the lower face 50 of the cylinder head cover 16.
  • the cylinder head 14 is fixed to the engine block 12 by a series of screws 52 while the cylinder head cover 16 is fixed to the cylinder head 14 by a series of screws 54.
  • the cylinder head cover 16 is delimited externally by a wall 56 and divided internally by several partitions 58 and 60 which extend parallel to the line of the cylinders.
  • the internal space or compartment 62 essentially delimited by the external wall 56 and by the partitions 58 and 60 constitutes the major part of the distribution box for the intake air between the long intake ducts 28 or the ducts short admission 66.
  • the intake box is completed by a cell 68 formed in the upper face 48 of the cylinder head 14 which faces the space 62 of the cover 16.
  • the short intake duct of the intake valve 36 is in fact constituted by a portion of intake manifold 66 formed in the cylinder head 14 and which opens into the cavity 68.
  • Each long intake duct 28 is formed in the cylinder head cover 16, is connected to the internal space 62 of this cover and opens into a long intake manifold 72 formed in the cylinder head 14.
  • the entire air intake device is therefore integrated into the upper part of the engine.
  • the partitions 58 and 60 and the outer wall 56 of the cover 16 also delimit two chambers 74 and 76 which receive the camshafts 40 and 42.
  • Rooms 74 and 76 are completed by complementary cells 78 and 80 formed in the upper face 48 of the cylinder head 14.
  • the chambers 74 and 76 are isolated from the distribution box 62 by the transverse partitions 82 and 84 which delimit them and in which upper half-bearings 86 and 88 are formed respectively which cooperate with corresponding lower half-bearings 90 and 92 to ensure the rotational mounting of the camshafts 40 and 42 on the cylinder head 14.
  • the assembly consisting of the cylinder head 14 and the cover 16 also performs the rotational mounting of the moving parts of the cylinder head.
  • a spark plug 91 is mounted in a cylindrical hole 93 in the cylinder head 14 which is extended by a corresponding hole 94 formed in the cover 16.
  • Injectors 96 are mounted laterally on the cylinder head 14 in injection conduits 98 which open in the vicinity of the heads of the valves 34 at the lower end of the long intake pipes 72.
  • the upper half-bearings 86 and 88 provided for receiving the camshafts are not formed directly in the cover 16 but in the caps of independent bearings 100 and 102 which are themselves located in rooms 74 and 76.
  • the invention is of course not limited to the embodiment which has just been described, the number of valves of each cylinder possibly being different, for example, as can the control of the intake, applications of the invention n not being limited to overhead camshaft engines.
