Definitions

  • the invention relates to a device for cooling the pistons of an internal combustion engine by means of a pump, which supplies oil to the piston from the lubricating oil circuit by means of a pump via an inlet line having an outlet opening, the oil inlet being regulated via a valve controlled as a function of engine parameters and the oil at least is sprayed against the underside of the piston.
  • a device of the type mentioned at the outset is already known (DE 42 43 571 C2), in which the piston cooling is inserted directly into the crankcase in the area of the bearing seats and is connected to a lubricant supply, so that oil is discharged from the piston underside via oil spray nozzles can.
  • the oil spray nozzles are designed in connection with the upstream pressure valves so that the oil spray nozzles are switched off from the lubrication supply when the machine is idling.
  • the oil spray nozzles are also inserted into the recesses provided in the bearing bracket. This should save additional lubricating oil channels for the other oil spray valves.
  • the object of the invention is to design and arrange a device for cooling the pistons of an internal combustion engine with a lubricating oil circuit so that the internal combustion engine is cooled only with certain parameters.
  • the lubricating oil circuit includes at least one main supply line to which a plurality of supply lines, each with an outlet opening, are connected, only one valve being provided in the main supply line.
  • valve as a pressure-independent, switchable valve designed and in the area of a End of the main supply line is provided.
  • valve as an electromagnetic Valve designed and engine parameters such as oil temperature, Water temperature or oil pressure, is controllable. Since that Valve is designed as an electromagnetic valve, leave it easily about the engine parameters, such as Switch oil temperature, water temperature or oil pressure, see above that it opens very specifically at the desired operating state and ensures the coolant supply to the piston.
  • valve with sensors of the engine and / or with the engine control unit is effectively linked in which the individual engine parameters are filed.
  • the supply line with their outlet opening designed as oil splashes at a distance arranged to at least one inlet opening provided in the piston and is in flow connection.
  • the feed line with its outlet opening concentric to the inlet opening provided in the piston is arranged. Due to the advantageous placement the outlet of the oil syringe in the area of the piston Optimal coolant supply in any position of the piston of the piston, as it also lasts for a long time Distance between the outlet opening of the feed lines and the inlet opening in the piston ensures transport to the piston is so that the coolant is targeted into the inlet opening enter the piston and at another point in the piston can exit again.
  • the feed line with its outlet opening in a certain position of the piston in the Intake opening of the piston protrudes. This ensures that no damage in any position of the piston the supply line can enter because even in the lowest Position of the piston (UT) the outlet opening or the outlet end the oil supply line into the opening of the piston can enter.
  • one or more oil channels in the piston are provided, at least one of which with the outlet opening the supply line of the oil circuit in flow connection stands, at least partially in an engine block or cylinder housing.
  • a device for cooling or for Lubrication of a reciprocating internal combustion engine with a cross section cylinder 2 shown and a crankcase 12 illustrated to which a combustion chamber 1 is assigned.
  • a piston 18 is above a piston pin 16 by means of a Connecting rod 15 mounted in the crankcase 12.
  • the piston 18 has a piston crown 20 and a piston skirt 21 and in upper area numerous ring grooves 22 for receiving piston rings 23 on.
  • the piston 18 is supported by the piston crown 20 and an upper piston surface or piston bowl 24 and a piston skirt 25 limited.
  • Oil channel 19 there is a circumferential one in the area of the piston outer surface 25 Oil channel 19, the one with an inlet opening 6, 6 'and on the other hand, be connected to an outlet opening 7, 7 ' can.
  • the oil channel 19 is in dashed lines indicated.
  • the oil channel 19 belongs to an oil circuit, which also includes an in belongs to an engine block 10 provided feed line 4.
  • the feed line 4 is connected to a main supply line 27.
  • the main supply line 27 also serves to supply pressure medium further not shown in the drawing Feed lines for further cylinders of the internal combustion engine and is supplied by a pump 11.
  • the feed line or the feed channel 4 each with the corresponding crankcase 12 in connection.
  • the feed line 4 points in the area an oil spray nozzle 26 at its outlet opening 5 arranged at a sufficient distance from the piston crown 20 is, so that when the piston 18 is in the UT position no damage to the feed line 4 can occur.
  • the supply line 4 or the oil spray nozzle 26 concentric to that provided in the piston 18 Inlet opening 6 of the oil channel 19 arranged so that in the position UT of the piston 18 part of the oil spray nozzle 26 or the associated supply line 4 into which the inlet opening 6, 6 'subsequent drilling can occur briefly.
  • the pump 11 switchable valve 17 which is designed as an electromagnetic valve and engine parameters, such as oil temperature, Water temperature or oil pressure can be controlled can.
  • engine parameters such as oil temperature, Water temperature or oil pressure can be controlled can.
  • a coolant supply when cold starting or when Overrun can have a negative impact on running behavior, noise, Emissions and fuel consumption of the internal combustion engine.
  • targeted cooling and / or clocked cooling becomes a major improvement in the engine's metrics or the overall efficiency.
  • the switchable valve 17 is not shown in the drawing Sensors of the engine and / or one in the drawing also not shown engine control unit in terms of effectiveness connected in which the individual motor parameters are stored. With this arrangement it is also possible to have valves inside the area of the oil syringe. Besides, it's after another embodiment possible instead of a separate one Oil channel or a separate feed line 4 the flow of each individual oil spray nozzle 26 depending on the operating parameters controlled by a separate valve.
  • the device for cooling and / or Lubrication of the piston 18 or the reciprocating piston internal combustion engine can the lubrication or cooling only after the cold start of the Motors are used, so that rapid combustion chamber heating can take place, which is delayed by early cooling would.
  • To counteract cooling of the combustion chamber it is advantageous, especially in the partial load range or overrun to avoid or reduce cooling channel loading.
  • FIG. 2 there are a plurality of supply lines to the main supply line 27 or feed channels 4 connected with oil spray nozzles 26, have the outlet openings 5 through which the Cooling oil is supplied to the piston 18.
  • An engine control unit 28 2, 3 can be operatively connected to the valve 17 be, the valve 17 between the pump 11 and the first Feed channel 4 or the oil spray nozzle 26 (Fig. 3) or between an oil pan 30 of the crankcase 12 and an oil spray nozzle 26 or a feed channel 4 is provided (Fig. 3).
