Definitions

  • the present invention relates to an engine with a new type of oil passage, specifically, it relates to an engine having intake valves at overhead.
  • the technical field of this invention is machinery manufacture.
  • JP H01 170703A discloses a valve system for an engine comprising a cylinder head and rocker shafts, in which oil passages are set in the cylinder head running across the cylinder head.
  • Such engine has the following deficiencies: 1.
  • a rather long cutting tool is required for processing the oil passage because of the lengthiness of the cylinder bank, which renders a relatively high requirement for the cutting tool, and which results in a undesirably higher processing cost;
  • the higher processing complexity may easily result in diameter disparity of the holes on both ends of the passage and further causes unbalanced oil pressures at two ends of the oil passage;
  • the oil inlet opening is set at one end of the cylinder bank resulting in low oil pressure at the rear end of the oil way; and the unduly established oil pressure at the rear end of oil passage causes that some work pieces cannot be lubricated timely, which in turn causes potential safety hazards such as abnormal wear and breakage of the camshaft.
  • the technical object of the present invention is to provide an engine with simpler structure, lower cost and reliable lubrication.
  • the main oil-feeding passage comprises an oil passage which extends from the bottom of the cylinder head to the main camshaft journal and an oil passage which extends from the bottom of the cylinder head to the interior of the camshaft bearing cap through a bolt hole at the center position of the camshaft bearing cap.
  • the bolt hole running through the cylinder head and the center position of the camshaft bearing cap can be provided in multiple forms.
  • the wall of the bolt hole may be provided with a groove for transmission of the oil; or the bolt fitting with the bolt hole may be designed into a structure that is partially hollow or with holes on the surface of bolt, the hollow part being used to transmit the oil.
  • the bolt hole running through the cylinder head and the center position of the camshaft bearing cap is a through hole consisting of three sections each having different diameters, and the middle section has bigger diameter than that of the outer sections at two ends.
  • the rocker and the hydraulic tappet are an integral build, the end of the camshaft is provided with oil drain aperture facing the camshaft, and the end of the hydraulic tappet is provided with oil hole splashing lubricating oil onto the cam of the camshaft.
  • the rocker shaft is provided with an oil outlet hole and an oil outlet groove at the positions where each rocker is installed; the oil outlet hole corresponds to the oil inlet hole of the oil passage of the rocker, and the oil outlet groove is opened on the supporting surface of rocker.
  • a small hole is provided in the middle of the oil outlet groove, the two side portions of the groove are symmetric to each other relative to the middle oil hole, and the length of the oil outlet groove matches the width of the rocker installation hole.
  • the rocker shafts include intake rocker shaft and exhaust rocker shaft, and the rockers include intake rocker and exhaust rocker.
  • the oil passage inside the camshaft bearing cap is the oil passage that extends to the central installation hole of the intake rocker shaft and to the central installation hole of the exhaust rocker shaft from the bolt hole in the middle position of the camshaft bearing cap.
  • the oil passage inside the camshaft bearing cap is the oil passage that extends to the holes of the secondary journals of camshaft from the installation holes at two sides of the intake rocker shaft and to the installation holes at two sides of the exhaust rocker shaft.
  • the oil passage inlet of the engine is provided at the middle position.
  • the lubrication oil enters from the middle part and is fed to two sides along the rocker shaft, so as to guarantee balanced and consistent oil pressure on both sides of engine and reduce the length of the oil passage. In this way processing of the oil passage becomes easier and requirements for the cutting tools are reduced.
  • the oil pressure on both sides can be quickly established, so that the camshaft, the rocker shafts and rockers can be reliably lubricated.
  • the main oil passage is provided inside the camshaft bearing cap and the rocker shaft, so that the difficulty in processing the cylinder head is reduced, the quality of the whole engine can be easily guaranteed, and the processing cost is also reduced.
