Definitions

  • the present invention relates to an internal combustion engine for a motor vehicle with a crankcase containing lubricating oil, to which a cylinder block is mounted with a plurality of cylinder bores, which are closed with a cylinder block mounted on the cylinder head with cylinder head covers to cover a valve mounted on the cylinder head valve mechanism, wherein means for guiding a the Level of the lubricating oil-determining oil dipstick are provided.
  • the field of application of the invention extends to all ⁇ lbadgeschmator internal combustion engines, which - in addition to electronic oil level measuring devices - are also equipped with a conventional oil dipstick for manual measurement of the oil level in the crankcase.
  • a disadvantage of this solution is that a number of separate components are required for fastening the steel pipe outside the internal combustion engine. This entails a corresponding installation effort. In addition, care must be taken during transport and storage of the internal combustion engine before its installation in a motor vehicle that the outer steel tube for the oil dipstick can not be damaged by external mechanical influences.
  • Deep hole drilling directly in the cylinder head and cylinder block are generated.
  • Such deep hole drilling cause due to the required drilling length of often more than 400 mm a corresponding manufacturing effort by machining.

  • the individual channels result after assembly of the aforementioned components the entire guide channel for the oil dipstick. There are no further assembly steps required. External sealing surfaces are completely eliminated. The effort is also reduced by the fact that other components omitted.
  • By the leadership of the oil dipstick within the engine also reduces the variety of variants, since now a single guide solution for all conceivable installation situations of the internal combustion engine can be used in a motor vehicle.
  • a separate guide tube made of plastic or other suitable material is arranged in the cast channel of the cylinder block.
  • the separate guide tube improves the sliding properties in the channel of the cylinder block, which has a fairly large length.
  • the guide tube can be provided at the upper end with an outer radial collar portion which cooperates with a corresponding recess in the channel for positioning the guide tube relative to the channel.
  • the cast channels for guiding the oil dipstick can also be used as a so-called blow-by channel for pressure equalization of the interior of the cylinder housing or as an oil return passage from the cylinder head to the crankcase.
