Definitions

  • the invention relates to a device for cooling at least one piston of an internal combustion engine.
  • German patent publication DE 102 06 769 A1 for operating an internal combustion engine with engine braking and controllable piston cooling, the piston cooling being reduced in engine braking mode.
  • the piston is not excessively cooled in engine braking mode.
  • the development of increased play between the piston and the cylinder wall and an associated increased flow of air from the combustion chamber into the crankcase chamber (blow-by) is thus avoided.
  • the object of the invention is to provide a method which ensures optimized piston cooling in such a way that the overall efficiency of the internal combustion engine is improved.
  • a check valve is used in a known manner in the main supply line, or one check valve is used for each supply line, and according to the invention the lubricating oil pump regulates the pressure in the lubricating oil circuit to adapt to different operating conditions for the internal combustion engine as a function of load.
  • a check valve may be used which operates with an increased opening pressure compared to a check valve in a system without a lubricating oil pump that is regulated as a function of load. In this manner unnecessary piston cooling is avoided in many operating conditions.
  • the lubricating oil pump is regulated as a function of additional operating parameters, in particular as a function of the rotational speed of the internal combustion engine and/or the temperature of the internal combustion engine and/or the coolant temperature of the internal combustion engine and/or the lubricating oil temperature.
  • FIG. 1 shows a first device according to the embodiments of the invention.
  • FIG. 1 shows a schematic illustration of a device for cooling the pistons 2 (or the at least one piston) of an internal combustion engine.
  • the device comprises a lubricating oil pump 10 which via a supply line 12 supplies the piston 2 with lubricating oil for cooling.
  • a check valve 14 is provided in the supply line 12 , between the lubricating oil pump 10 and the outlet opening 12 a of the supply line 12 .
  • the lubricating oil pump 10 is controlled by a control unit 20 which ensures that the lubricating oil pump 10 is regulated as a function of the determined load on the internal combustion engine.
  • the lubricating oil pump 10 preferably is controlled via the control unit 20 (a motor control unit, for example) by means of a characteristic field regulation as a function of a plurality of operating parameters.
  • the control is performed as a function of the engine temperature, the engine rotational speed, and/or the lubricating oil temperature.
  • the check valve 14 may be designed for an increased opening pressure.
  • a check valve 14 for conventional, non-load-dependent regulation of the lubricating oil pump of an internal combustion engine in a motor vehicle is designed for an opening pressure of approximately 2 bar (in order to ensure sufficient piston cooling in all critical circumstances)
  • a check valve 14 is used having an opening pressure that is higher by comparison, for example, an opening pressure of 3 bar.
  • the plurality of valves may be replaced by the use of a single valve in a main supply line which is connected to the supply lines (not illustrated).
