Definitions

  • the invention relates to an internal combustion engine with a cylinder crankcase that has at least one cylinder covered by a cylinder head, in particular according to the preamble of claim 1.
  • each cylinder of the internal combustion engine according to the invention has a cylinder cooling chamber and each cylinder head has a head cooling chamber, the individual cylinder cooling chambers and the individual head cooling chambers being connected to one another and the cylinder cooling chambers and the head cooling chambers as a whole being connected in series.
  • the cooling oil is inevitably passed through all the cooling oil chambers of the internal combustion engine without the need for special cooling oil distribution lines.
  • the thermal capacity of the cooling oil is used to the maximum by connecting all the cold rooms in series.
  • the cylinder cooling chamber of an end cylinder via an inlet line with the oil pump and the cylinder cooling chamber of the opposite face cylinder with a drain line in flow connection, and that a throttle is arranged in the drain line, before which an inflow line branches off to the head cooling rooms and behind which a return line from the head cooling rooms opens into the drain line.
  • the throttle causes part of the cooling oil to inevitably get into the head cooling spaces after leaving the cylinder cooling spaces, while part of the cooling oil flows directly through the throttle.
  • each individual head cooling chamber is in flow connection with the return line via a web bore and a connecting bore branching therefrom. In this way, the thermally highly stressed cylinder head sections between the gas exchange valves are cooled intensively.
  • the direction of flow through the head cooling chambers is opposite to the direction of flow through the cylinder cooling chambers and the return line. This ensures that the supply of the cooling oil and its removal takes place at different ends of the cylinder block, which results in a simple, clear cooling oil guidance.
  • An advantageous embodiment of the invention by means of which the bearings of rocker arms are in flow connection with the return line, ensures that the structural outlay for lubricating the rocker arm bearings is minimized due to the spatial proximity of the return line and rocker arm bearings.
  • an air-oil heat exchanger is arranged in the oil circuit between the cooling oil spaces and the lubrication system. In this way, the lubrication system is supplied with relatively cool and therefore particularly stable lubricating oil.
  • a thermostat is arranged in the oil circuit between the cooling oil chambers and the air-oil heat exchanger, which thermostat controls a heat exchanger inlet line and a heat exchanger bypass line. In this way, the internal combustion engine is warmed up quickly, which has a favorable effect on fuel consumption and pollutant emissions.
  • an oil filter with a dirty oil chamber and a clean oil chamber is arranged in the oil circuit, the dirty oil chamber with the heat exchanger bypass line and via a heat exchanger return line with the air-oil heat exchanger and the clean oil chamber with the lubrication system in flow connection.
  • an outflow line branches off from the heat exchanger bypass line in the flow direction in front of the oil filter and opens into an oil pan, and that a pressure-maintaining valve that opens towards the oil pan is arranged in the outflow line. This ensures the oil pressure required for proper lubrication.
  • a heating inlet branches off from the outflow line in the flow direction behind the pressure holding valve and a heating return flows into the outflow line downstream of this branch, a heating pressure valve opening towards the oil pan opening in the outflow line between the heating inlet and the heating return and one in the heating return Outflow line opening discharge valve are arranged.
  • the heating pressure valve ensures a forced flow through the heating heat exchanger as soon as it is switched on.
  • the leakage protection valve ensures that the heat exchanger is always filled with oil and thus a clear control of the oil level of the internal combustion engine is possible.
  • the sum of the opening pressures of the pressure holding valve and the heating pressure valve is at least 3 bar and the opening pressure of the leakage protection valve is approximately 0.3 bar. In this way, the required minimum oil pressure is ensured and idling of the heat exchanger is reliably prevented.
  • a melting body holding the thermostat housing at a distance from the wall is arranged between the thermostat housing and the wall on which the thermostatic piston is displaced against the force of a spring.
  • This insertion of a melting body causes the valve body controlled by the thermostat to be shifted by the same amount as the oil thermostat during initial commissioning.
  • the heat exchanger inlet line is at least partially opened during initial commissioning.
  • the melting body is otherwise designed so that it melts when the internal combustion engine is started up when the internal combustion engine is warming up, thus enabling the oil thermostat to function normally.
  • the melting body is made of a material of this type which does not impair the oil circuit of the internal combustion engine.
  • the melting body is a melting ring.
  • This design has the advantage that the thermostat housing rests on the entire surface of the melting ring and jamming is excluded.
  • the melting body is made from a wax. Such a wax ring, after it has melted away, does not impair the oil circuit.
  • the oil is sucked out of the oil pan 14 via a suction basket 34 by the oil pump 1 and conveyed into the feed line 20. If the oil pressure is too high, the control valve 33 responds, which is arranged in a branch of the feed line 20 downstream of the oil pump 1 in the direction of the oil pan 14.
  • the oil reaches the cylinder cooling chambers 3a to 3d connected in series from the inlet line 20.
  • the oil flows out of the cylinder cooling chamber 3d into an outlet line 22 in which a throttle 23 is arranged.
  • an inlet line 24 branches off from the outlet line 22 and leads into the series-connected head cooling chambers 4a to 4d.
  • the individual head cooling chambers 4a to 4d are each connected via a web bore 21 and a connecting bore 29 to a return line 25 which leads the oil together with the outlet line 22 into an oil thermostat 6.
  • Rocker arms 26 arranged in the cylinder head are connected with their bearings 27 to the return line 25.
  • the oil thermostat controls a heat exchanger inlet line 7 and a heat exchanger bypass line 8.
  • the oil flows through the heat exchanger inlet line 7 to an air-oil heat exchanger 5 and further via a heat exchanger return line 12 to a dirty oil chamber 10 of an oil filter 9. When the oil is cold, the oil passes through the heat exchanger bypass line to the dirty oil room 10.
  • the oil After flowing through the oil filter 9, the oil enters the clean oil chamber 11 and from there into the lubrication system 2.
  • An outflow line 13 branches off from the heat exchanger bypass line 8 and opens into the oil pan 14.
  • a pressure-maintaining valve 15 opening towards the oil pan 14 is arranged in the outflow line 13. This serves to maintain a minimum pressure in the oil system.
  • a heating inlet 16 branches off from the outflow line 13 downstream of the pressure holding valve 15 and leads to a heating heat exchanger (not shown). From there, the oil passes via a heating return 17 and an outlet protection valve 19 opening in the direction of the oil pan back to the outflow line 13 and via this into the oil pan 14. Between the heating inlet 16 and the heating return 17 there is a heating pressure valve opening in the outflow line 13 towards the oil pan 14 18. This causes the heating heat exchanger to be forced to run through it.
  • the pressure holding valve 15 connected in series and the heating pressure valve 18 determine the maximum oil pressure in the oil circuit.
  • the leakage protection valve 19 prevents the heating heat exchanger from running dry and thus prevents the oil level in the oil pan 14 from being falsified.
  • the view of the oil thermostat 6 shown in FIG. 2 shows the oil thermostat 6 inserted into a housing, which has a thermostat housing 35 and a valve body 36 attached to it.
  • the thermostat housing 35 is normally supported by a piston 37 against a wall 38 which is formed by a screw plug 39.
  • the oil thermostat is pressed by a spring 40 in the direction of the wall 38.
  • the oil coming from the cooling oil circuit through the individual cylinders and the individual cylinder heads passes through the combined drain line 22 and return line 25 into the valve body, flows through it and passes through a control opening 41 into the valve body 36 into the heat exchanger bypass line 8
  • a melting ring 42 is arranged, the thermostat housing 35 and the valve body 36, including the control opening 41, are pushed out of their rest position by a certain amount.
  • the control opening 41 also releases the heat exchanger inlet line 7, at least in a partial cross section, so that oil can flow into this line even before the internal combustion engine is started up for the first time. This ensures that the specified amount of oil can be filled in when the internal combustion engine is filled for the first time.
  • the melting ring 42 melts away with increasing heating of the internal combustion engine or the oil, so that when the oil or the internal combustion engine cools down again, the thermostat housing 35 or the piston 37 comes to rest against the wall 38 and thus in the cold state, the entry of oil into the heat exchanger supply line 7 according to FIG. 3 is prevented.
