Definitions

  • the present invention relates to a internal combustion engine intended to equip including a motor vehicle.
  • the current invention relates more particularly to the circuit air intake.
  • the air intake circuit of an engine consists of upstream downstream in the air flow direction of an air filter, a butterfly housing (in the case in particular of spark ignition engines), a formed manifold a cavity or plenum from which a plurality leave of ducts and, provided intake ducts in the cylinder head, these conduits formed in the cylinder head opening into the combustion chambers by holes selectively closed by valves.
  • Elements of the air intake circuit other than the intake ducts in the cylinder heads are usually housed outside the engine in the engine compartment. Given the evolution of motor vehicle design, the dimensions of this engine compartment are today more and more reduced and so it is important to make this more and more compact air circuit.
  • the object of the present invention is therefore improve the existing state of the art by support the entire external air circuit of the engine by the upper part of the engine.
  • the internal combustion engine according to the invention is of the type comprising a circuit air intake comprising an air filter, a throttle body and an intake manifold, intake manifold consisting of a cavity distributor and a plurality of pipes to supply the conduits corresponding intake housings in the cylinder head.
  • the combustion engine internal is characterized in that the collector intake, throttle body and air filter are positioned above the cylinder head cover.
  • the upstream and downstream ends of the throttle body are directly fitted into openings air filter and manifold of admission.
  • the upstream and downstream ends of the throttle body are radially surrounded by an O-ring intended to sealing and maintaining the position of these ends in the corresponding openings air filter and intake manifold.
  • the engine includes a gas decantation chamber casing formed directly from foundry, this settling chamber being defined by a first cavity formed on the upper face of the cylinder head cover and a second shaped cavity complementary in a cover intended for come close said first cavity.
  • the cavity intake manifold dispatcher rests directly on the lid closing the chamber decantation of the crankcase gases provided in the cylinder head cover, a simple bore calibrated through the bottom wall of the cover cooperating with a corresponding opening made through the wall lower next to the distribution cavity allows to recycle crankcase gases directly in the intake manifold.
  • the intake manifold and throttle body are attached directly to the chamber cover decantation of the crankcase gases.
  • the gas decantation chamber cover housing incorporates from foundry an element of gas transfer line to the air intake circuit, this pipe element opening at its end downstream by an end piece projecting from the above the cover, this nozzle being adapted for enter the distributor cavity of the collector admission through a corresponding opening.
  • the gas decantation chamber cover housing incorporates a tubular conduit element opening into the settling chamber and intended to cooperate with an opening corresponding to the air filter, this element of duct for recycling crankcase gases directly into the air filter.
  • a cylinder head cover 1 covering the cylinder head 10 of a internal combustion of the multicylinder type intended in particular to equip a motor vehicle.
  • the engine also comprises, in a conventional manner, a casing not shown, formed by a cylinder block with an oil tank at the bottom.
  • an open cavity 2 is formed defining the lower part of the recovery chamber 3 and settling of escaped combustion gases in the crankcase through the different games Operating.
  • the cavity 2 is closed by a cover 4 coming from foundry which comes to be fixed on the top of the cylinder head cover 1 by appropriate means.
  • This cover 4 has an interior cavity 5 of shape substantially combined with that of the cavity 2, defining the upper part of the chamber decantation 3.
  • the settling chamber 3 is located thus, according to the embodiment described, shared approximately equally between the cylinder head cover 1 and cover 4. Obviously, it is possible to change the proportions respective of the settling chamber contained in the cylinder head cover 1 and the cover 4.
  • the collector intake 23, throttle body 30 and filter 50 air from the engine air intake circuit are arranged above the cylinder head cover 1 and relies on the latter in particular through cover 4.
  • the intake manifold 23 which is conventionally consists of a distributing cavity or plenum 25 and a plurality of pipes individual 26 intended to supply the conduits correspondents in cylinder head 10, is shaped so that the distribution cavity 25 is positioned substantially in line with the cover 4.
  • the intake manifold is attached directly on the cover 4 by means of screws fixing not shown cooperating with flanges 28 carried by the intake manifold 23 and counter flanges 48 arranged on the top of the cover 4.
  • the counter flanges 48 are adapted to also serve as flanges to fix the cover 4 on the cylinder head cover 1.
  • the cover 4 also integrates from foundry, a pipe element 40 which opens at its downstream end by a nozzle 41 projecting from the top of the cover 4. This tip 41 is adapted to penetrate the intake manifold 23 through opening 22 and lead into the distributing cavity 25 substantially above the orifice 12.
  • This pipe element 40 can be connected at its downstream end to the circuit of recirculation of crankcase gases to the purging of fuel vapors trapped in the canister or even to the air intake circuit slowed down if the latter is not integrated to the throttle body 30.
  • the intake manifold 23 present by elsewhere, a circular opening 29 formed between the two flanges 28, through the side wall opposite the pipes 26 of the distributor cavity 25 of collector 23. It is directly in this opening 29 which is fitted the downstream end of the throttle body 30. This downstream end is surrounded by an O-ring 31 which ensures perfect sealing between the collector intake and throttle body 30 and the holding this end in position in the corresponding opening 29 of the collector of admission.
  • the butterfly case 30 just like the intake manifold 23 is directly attached to cover 4 by means of fixing screws not figured cooperating with flanges 33 carried by the butterfly housing 30 and counter flanges 43 arranged on the lateral face opposite the cover 4.
  • the upstream end of the throttle body 30 is fitted similarly to the downstream end in a corresponding opening 59 of the filter air 50. Similarly, a joint O-ring seal surrounding radially the upstream end of the throttle body 30 ensures the tightness of the assembly between the latter and the air filter 50.
  • the butterfly case is thus directly connected to the intake manifold on the one hand and the air filter on the other hand without additional connection lines and without special fixing device.
  • the immediate proximity of the air filter 50 cover 4 also makes it possible to operate directly connecting the room from decantation 3 at the intake circuit upstream of the butterfly flap. To do this, the cover 4 integrates a tubular conduit element 45 intended to come directly into a corresponding opening 51 of the air filter 50.
  • the mounting of different components of the circuit air intake and connection of this one to the additional introductory circuits gas can operate extremely simple, due to a reduced number of parts, parts obtained mainly from molding and do not requiring only a limited number of operations machining.
