Definitions

  • the invention relates to a cooling and lubrication system of an internal combustion engine with a pump, a cooling circuit and a lubrication circuit.
  • the object on which the invention is based is seen in creating a cooling and lubricating system for an internal combustion engine which results in the smallest possible design or optimal utilization of a heat exchanger.
  • the size of the volume flow can be measured independently of one another, both through the cooling circuit and through the lubrication circuit, so that the components, e.g. B. a heat exchanger in the cooling circuit only the really required volume flow is supplied.
  • An internal combustion engine 10 is equipped with a cylinder head 12, an engine block 14, a collecting container 16 for liquid, in particular for oil, and with a pump 18.
  • liquid used below includes both cooling liquid and lubricating liquid.
  • a plurality of cylinders 20 are provided, one of which is shown, and in each of which a piston 22 moves back and forth, which are connected to a crankshaft 26 via connecting rods 24.
  • the cylinder head 12 has inlets 28 and outlets (not shown), valves 30, valve seats 32 and rocker arms 34 driven by a camshaft 35.
  • the pump 18 draws liquid from the collection container 16 and pumps it to a main gallery 36, from where it flows back to the collection container 16 via a cooling and a lubrication circuit which are connected in parallel with one another.
  • the liquid flows from the main gallery 36 to a filter 40 via a line 38.
  • This filter 40 is bypassed via a bypass line 42 if it is clogged and a pressure control valve 44 then opens.
  • the liquid can also be supplied to the collecting container 16 via a further pressure control valve 46 and a line 48.
  • a line 50 also runs to one Lubrication gallery 52, which is incorporated into the engine block 14.
  • the lubrication gallery 52 supplies liquid to a conventional lubrication circuit of the internal combustion engine 10, which in particular contains main bearing lubrication channels 54 and spray nozzles 56.
  • a line 58 also leads from the lubrication gallery 52 to a lubrication gallery 60 in the cylinder head 12, which supplies liquid to the bearings of the rocker arms 34 and the camshaft 35.
  • the liquid consumed in the cylinder head 12 collects in a gallery 62 and flows from there via a line 64 back to the collecting container 16.
  • the cooling circuit of the internal combustion engine 10 includes a conduit 100 that carries liquid from the main gallery 36 to a gallery 102 near the top of the cylinders 20. From there, the liquid flows to annular cooling grooves 104, via which the upper region of the cylinders 20 is cooled, and then on to a gallery 106.
  • a conduit 108 conducts fluid from gallery 102 to gallery 110 in cylinder head 12. From this gallery 110, the fluid flows through annular grooves 112, which are arranged around valve seats 32 of the exhaust valves, to gallery 114 in cylinder head 12 which flows out again via lines 116 or 118.
  • the heated liquid is fed from the internal combustion engine 10 via a control valve 120 to a heater 122 in a room 123, in particular in a driver's cab of an agricultural tractor, and from there via a line 124 to the collecting container 16.
  • a control device 121 for the control valve 120 is preferably provided in the space 123 so that the amount of the hot liquid which is supplied to the heater 122 can be set by an operator.
  • Line 118 leads liquid from the gallery 114 in the cylinder head 12 to the gallery 106 in the engine block 14, from where it flows via a line 126 to a temperature-controlled thermostatic valve 128.
  • This valve 128 is preferably controlled as a function of the liquid temperature in the lubrication gallery 52, which is detected by means of a transmitter element 130.
  • the transmitter element 130 is designed in the manner of a temperature sensor, which is accommodated in the engine block 14 and is exposed to the liquid in the lubrication gallery 52.
  • Valve 128 supplies hot liquid from line 126 to either reservoir 16 via bypass 131 or to heat exchanger 134 via line 132.
  • the heat exchanger 134 contains series-connected first and second stages 134a and 134b, a first outlet 136, a second outlet 138 and a drain 139.
  • the first outlet 136 contains only liquid which has been taken from the first stage 134a.
  • the second outlet 138 receives liquid which has flowed through both stages 134a and 134b. Accordingly, the liquid that has only flowed through the first stage 134a and exits at the first outlet 136 will be hotter than liquid that exits at the second outlet 138.
  • the liquid in the line 132 can be approximately 140 ° Celsius, at the first outlet 136 approximately 110 ° Celsius and at the second outlet 138 approximately 60 ° Celsius.
  • the heat exchanger 134 is configured to allow a greater volume flow to the first outlet 136 than to the second outlet 138. Accordingly, the additional volume of the heat exchanger 134 required to bring the liquid to the lowest temperature at the second Cool down outlet 138, not flowed through by the total amount of liquid flowing to heat exchanger 134, and the flow through second outlet 138 is only about half the amount of liquid exiting first, hotter outlet 136.
  • a line 140 the cooled liquid from the first outlet 136 of the heat exchanger 134 to the collecting container 16. Liquid is withdrawn from the second outlet 138 via a further line 142 and delivered to a charge air cooler 144, from where it also flows via a line 146 to the collecting container 16.
  • an additional lubrication line can be provided in order to conduct liquid for lubrication from the filter 40 out of the turbocharger and back into the reservoir 16.
