Definitions

  • the present invention essentially relates to an internal combustion engine comprising a gas intake and oil removal device as described in the preamble of claim 1.
  • This single piece forming a cylinder head cover advantageously makes it possible to reduce the total height of the engine under the hood of the vehicle, so that the engine thus has a minimum bulk and compatible with a modern and somewhat plunging shape for the front part of the body of the vehicle.
  • the present invention aims to solve these problems by proposing a cylinder head cover of the type defined above and which is incorporated a gas deoiling system and filling the crankcase oil, which does not affect the overall dimensions and height of the engine.
  • the subject of the invention is an internal combustion engine comprising a device for admission and deoiling of the crankcase gases and of the type essentially comprising a cylinder head surmounting several cylinders to which are respectively connected several gas intake conduits which form with a manifold distribution of these gases a rigid part, characterized in that said rigid part, constituting a cylinder head cover, rests on a partition or the like secured to the cylinder head and forming, on one side of the partition, a hollow space connected to the casing of the engine by channels, and comprises, on the other side of the partition, a chamber for removing oil from the gases sucked back by the engine intake circuit, which is connected on the one hand to the manifold by openings, and on the other hand to said hollow space by passages passing through said partition.
  • the aforementioned partition integral with the cylinder head constitutes a camshaft support fixed on the top of the cylinder head.
  • the engine is filled with oil by a chute adjacent to the deoiling chamber and communicating by a passage with the hollow space under the partition.
  • the aforementioned passages are constituted by tubular connections mounted between the partition and the aforementioned rigid part.
  • the openings connecting the chamber oil removal at the manifold are associated with a pressure regulator integrated into the rigid part.
  • FIG. 1 is a view in vertical section of the upper part of an engine equipped with a device according to this invention, the section being taken along the line I-I of FIG. 2.
  • Figure 2 is a top plan view of the top of the engine.
  • Figure 3 is a sectional view along lines III-III of Figure 2.
  • Figure 4 is a sectional view along line IV-IV of Figure 1.
  • the part 4 forming cylinder head cover rests on a partition 5 belonging to a support 6 for a camshaft 7, which support is tightly fixed on the top of the cylinder head 1 and somehow forms an intermediate piece between said cylinder head and the cylinder head cover 4.
  • Such a construction advantageously makes it possible on the one hand to provide under the partition 5 between the camshaft support 6 and the cylinder head 1 a hollow space 8, and to provide d on the other hand, in the cylinder head cover 4, and on the other side of the partition 5, a chamber 9 for removing oil from the gases coming from the lower casing of the engine, re-aspirated by the intake circuit 2 and recycled to the engine.
  • the hollow space 8 is connected to the oil sump (not shown) of the engine by channels identified at 10 in FIG. 3 and at 11 in FIG. 1.
  • the oil removal chamber 9 is connected on the one hand to the distribution manifold 3 by openings 12, 13 which will be described in detail below, and this oil removal chamber 9 is connected on the other hand to the hollow space 8 by passages 14, 15 passing through the partition 5 forming part of the camshaft support 6 7.
  • the engine oil can be filled by a chute 16 (FIG. 1) integrated into the cylinder head cover 4 and adjacent to the deoiling chamber 9, this chute communicating through a passage 17 with the hollow space 8 which itself communicates with the crankcase of the engine through the channel 11.
  • a plug 18 has been shown which, as known per se, allows the oil inlet to the shutter 16 to be closed.
  • the passages 14, 15 and 17 above mentioned are respectively constituted by tubular connections R mounted between the partition 5 and the rigid piece forming a cylinder head cover 4, said connections R providing a tightness at the joint surfaces between the partition and the cylinder head cover.
  • FIG. 20 shows a pressure regulator advantageously integrated into the rigid part or cylinder head cover 4 and in which the previously mentioned openings 12, 13 are provided and allowing communication between the chamber 9 and the distribution manifold 3 as long as the vacuum in the collector is less than a determined value.
  • this regulator is incorporated into the cylinder head cover 4 so that the height of the engine remains minimal with respect to the hood C of the vehicle, and, in the same spirit, the manifold 3 is disposed laterally with respect to the chamber 9 and the intake ducts 2 are juxtaposed with the deoiling chamber 9 so as to also give the engine or more precisely to the cylinder head cover 4, a minimum height and therefore a Sufficient free space vis-à-vis the hood C of the vehicle.
  • the space between the hood C of the vehicle and the engine is optimally used by nesting in the cylinder head cover 4 in particular for oil removal functions from the gas of the casing and of the oil filling of this casing, which functions are closely associated with the manifold-distributor 3 in the free space between the intake ducts 2, and will be described below.
  • the gas deoiling function is performed as follows.
  • the gases emitted in the engine casing rise into the oil removal or decantation chamber through the conduit 10 of the cylinder head 1, then through the passages 14 formed by the tubular connections R as can be seen in Figures 3 and 4 in particular.
  • the suction of these gases is carried out thanks to the vacuum which prevails in the manifold-distributor 3 which communicates with the chamber 9 through the openings 12 and 13, and this through the pressure regulator 20 whose valve 20a limits the suction crankcase gases to the intake in the event of a high vacuum in the manifold.
  • the oil in suspension in the gases is collected in the chamber 9 and returns to the engine oil pan via successively the passages 15 and 19, the hollow space 8 and the channel 11 in the cylinder head 1.
  • the gases cleared d oil are on their side, sent with air or the air-fuel gas mixture to the engine cylinders via the intake ducts 2, as shown by arrows in Figures 1 and 2.
  • the oil filling function it takes place through the chute 16 which is in communication with the hollow space 8 via the passage 17, the oil flowing towards the engine through the channel 11 in the cylinder head 1.
  • a one-piece multi-function cylinder head cover was therefore produced according to the invention, constituting a compact intake sub-assembly and allowing the improvement of the style, in particular at the level of the hood of the vehicle.
