Definitions

  • the present invention generally relates to a cylinder head cover for an internal combustion engine and more particularly to such a cylinder head cover equipped in particular with an air filter and a decanter for oil from the crankcase gases.
  • a molded metal cylinder head cover attached to the internal combustion engine and connected to the air circuit and to the crankcase gas recovery circuit by numerous hoses and collars, which increases the costs of production and complexity of the powertrain.
  • the object of the present invention is to eliminate the above drawbacks by proposing a cylinder head cover of molded material for an internal combustion engine which comprises an air filter connected to the intake system of the engine and which is integrated by molding. to the cylinder head cover.
  • the cylinder head cover comprises a settling chamber integrated by molding and communicating on the one hand with the engine casing and on the other hand with the intake system so as to suck the gases from the sump separated from oil particles.
  • the decantation chamber comprises a decantation well to which are connected at least two end pieces, integrated by molding in the cylinder head cover, for the connection of the decantation chamber to the casing and to the intake system to the help two communication lines.
  • the cylinder head cover comprises a channel for filling the crankcase oil integrated by molding in the cylinder head cover.
  • the air filter comprises a chamber integrated by molding into the cylinder head cover, intended for the reception of a filter cartridge, the chamber being extended by a chamber for mixing fresh air and hot air also integrated by molding in the cylinder head cover.
  • the air filter further comprises a cover portion, removably attached to the cylinder head cover so as to access the filter cartridge and comprising a connection channel between the decantation chamber and the intake circuit so as to suck up the gases. from the settling chamber.
  • the cylinder head cover comprises external ribs forming a groove integrally molded with the cylinder head cover and intended for fixing the electrical wires of the spark plugs of the engine.
  • oil filling channel is concentric with the settling well.
  • the cylinder head cover according to the invention is fixed to the upper part of the bearing caps of at least one camshaft of the engine.
  • the cylinder head cover is made of a plastic material.
  • the cylinder head cover according to the invention is compact, aesthetic and improves the acoustics of the engine. by filtering out distribution noise.
  • the molded cylinder head cover according to the invention comprises a body 1 serving as a cover in its lower part to the bearing caps of the camshaft (not shown).
  • the body 1 and the caps are assembled one on the other using, for example, fixing screws V.
  • the body 1 comprises several chambers which are distributed close to and contiguous with the lower part forming a cover.
  • the body 1 comprises in a lateral part a chamber 2, extending longitudinally to the axis XX ′ of the camshaft and into which fresh air is supplied by a front end piece 3, integral with the outer wall 2a delimiting the chamber 2, connected to a fresh air intake hose (not shown) connected to an engine air intake (not shown), for example, using a hose clamp.
  • a fresh air intake hose not shown
  • an engine air intake not shown
  • a hose clamp In a lower part of the chamber 2 is formed another end piece 4 intended to be connected to a supply line (not shown) of hot air.
  • This chamber 2 thus connected to the air intake and to an air heating part, connected to the exhaust manifold, makes it possible to obtain a mixture of fresh air and air heated by said manifold.
  • bedroom 2 is located under and adjoins another prismatic chamber 5 which communicates with it by a gas passage (not shown) such as for example an orifice in a common partition separating the two chambers 2 and 5.
  • a cartridge 6 for filtering the fresh air / hot air mixture is removably attached to a lateral face 5a delimiting the chamber 5 approximately comprised in a plane parallel to the vertical plane passing through the axis X-X ′.
  • This lateral face 5a delimits, with the lower wall 1a of the body 1 forming the bearing cover of the engine camshaft, a space for receiving a removable part forming the cover 7, allowing access to the filter cartridge 6.
  • This cover 7 is fixed to the body 1 using two elastic tabs 8 which snap onto protuberances or projections 9 formed, for example by molding, on the upper wall 5b of the chamber 5, and two fixing screws 10 screwing respectively into two bosses 11 secured to the wall 1a.
  • the cover 7 comprises, integral with a wall 13 and opposite to the filter cartridge 6, a connection end piece 14 connected to a hose, fixed for example using a collar, for the passage of the mixture. fresh air / hot air filtered to the engine intake system (not shown).
  • the settling chamber 18 is located laterally to the cover 7 and to the chamber 5 and comprises in its central part a settling well 19, which is substantially cylindrical.
  • the well 19 extends from bottom to top in the settling chamber 18, serves as an oil filling pipe (also referenced 19) concentric with the well 19 and opens at its lower end into the cylinder head (not shown).
  • the well 19 is closed at its upper end by a removable plug 20.
  • the well 19 is provided with a bolt shield grid (not shown).
  • the decantation chamber 18 is connected on the one hand with the engine casing by a hose D1 (symbolized in phantom) connecting to a radial end piece 21 of the decantation chamber 18 and on the other hand with the system of admission by another hose D2 (also symbolized in phantom) which is connected to a second radial nozzle 22 of the chamber 18 similar to the first nozzle 21.
  • hose D1 symbolized in phantom
  • another hose D2 also symbolized in phantom
  • This circuit allows the suction of the engine crankcase gases, after the oil particles suspended in the gas coming from the crankcase have been separated from this gas by decantation on the walls of the chamber 18.
  • the air filter F, the settling chamber 18, and the part forming the cover of the bearing caps of the camshaft are connected in one piece by molding of the body 1.
  • external ribs 23 are formed on a wall of the lower part of the body 1 forming a cover for the camshaft bearing caps. These ribs 23 are integrally molded with the body 1 form combs intended to retain electrical wires of spark plugs of the engine.
  • a compact, simple and economical cylinder head cover was thus produced, making it possible to reduce the time necessary for its assembly and maintenance.
