Definitions

  • the present invention relates to an intake system for internal combustion engines and including a filter housing with an air intake opening, a filter element and at least an air outlet tube, as seen in the flow direction of the air, and which air outlet tube is arranged to communicate with the engine inlet manifolds, which form an integral unit with the bottom part of the filter housing.
  • All internal combustion engines have an air cleaner for the engine air intake.
  • the main function of the air cleaner is to keep away dust and other particles from the carburettor and the cylinders.
  • the air filter prevents dust or dirt from blocking jets and causing wear on pistons and cylinders.
  • the cleaner also functions as silencer, as it muffles the intake noise from the carburettor and the air cleaner housing suppresses the resonance which occurs due to the air pressure variations in the inlet manifolds.
  • the object of the present invention is to provide an intake system of the type mentioned in the introduction, which exhibits a compact and space-saving construction. According to the invention this has been achieved in that the top part of the inlet manifolds are designed to form the lowermost border of the filter housing and to provide a support for the filter element.
  • Fig. 1 discloses a section through the intake system.
  • Fig. 2 discloses in a perspective the intake system according to the invention without filter, and without fuel injection valve.
  • the intake system incorporates a filter housing 10 with an air intake 11, a filter element 12 and at least one air outlet tube 13.
  • the filter housing 10 encases the replaceable, tubular filter element 12.
  • the air intake 11 is placed at one gable of the filter housing 10, whereas the outlet tube 13 is connected to the tubular opening of the filter element 12. From the air intake 11 the air is led via an air space 14 extending around the filter element, through the filter element 12 and to the air outlet tube.
  • the outlet tube 13 comprises a throttle valve 15 and ends into a common space from where the induction air is distributed to the inlet manifold 16 of the different engine cylinders.
  • the inlet part 17 of these inlet manifolds 16 is horn-shaped and has an inlet opening 18, which communicates with the outlet tube 13, from where the induction air is led on to the inlet manifold 16 via an air room in the horn 17.
  • the inlet manifold 16 has an upper mainly plane portion 19, against which a part of the filter housing 10 connects and it thus forms a part of its lower border. A very compact and space-saving construction is hereby achieved.
  • FIG. 2 In fig. 2 is shown an intake system for a six cylinder engine, having one inlet manifold 16 each.
  • the outlet tube 13 from the filter housing 10 is centrally located and the air is distributed from this point to all six inlet manifolds 16.
  • the filter element 12 (not shown) is positioned direct on the package forming the intake system, whereby the upper mainly planar portion 19 of the inlet manifolds 16 form the bottom of the filter housing.
  • the portion 19 of the inlet manifolds 16 connecting to the filter housing 10 are curved but may also be planar, the filter housing thereby being given a corresponding shape.
  • the filter element 12 itself is positioned against a sealing ring 22 in a groove 24, which has a shape corresponding to the cross section of the filter element, which in the example shown is oval.
  • Fuel is supplied to the outlet part of the inlet manifold 16 via a fuel injection valve 20, which is screwed into a threaded bore 23 at the upper part of the inlet manifold 16, near its outlet opening.
  • the fuel pipe 21 of the injection valve is positioned to a part of its length in the air space 14 of the filter housing 10, which air space communicates with the air intake 11.
  • the fuel supply pipe can be embedded and form a unit with the inlet manifold 16 and also in this case a part of the fuel pipe can be placed into the air space 14 of the filter housing 10.
