Definitions

  • the invention relates to a lubricating oil circuit for an internal combustion engine with a lubricating oil pump, which, if necessary, an oil cooler and a filter device through a main pressure line oil to storage locations of the internal combustion engine and to further distant storage locations of additional units, for. B. an exhaust gas turbocharger, promotes.
  • the additional units such. B. connect the exhaust gas turbocharger via a connecting line to the main pressure line of the internal combustion engine and provide a drain line between the turbocharger and the oil sump.
  • the connection point of the connecting line lies behind the lubricating oil cooler and the filter device for the lubricating oil, as well as behind other parts of the lubricating oil circuit such as supply lines etc. due to the necessary cooling and filtering of the oil supplied during engine operation in the flow direction Partially or completely clear, so that each time the engine is restarted, these spaces must be filled before the full oil pressure builds up and the lubricating oil can press into the bearing points.
  • nachteili g t are the more remote bearing points of auxiliary units, such as the bearings of the arranged generally level with the upper edge of the engine or even higher exhaust gas turbocharger.
  • oil of sufficient pressure in bearing points may only occur with a such a time delay that this does not adversely affect unloaded start-up and a correspondingly heavily delayed or gradual load transfer, for rapid load transfer such as occurs in the case of immediate standby units, the time when sufficient pressure oil is available is too late. This can result in severe damage to the bearing points, unless a continuous or intermittent oil supply is ensured by complex oil lubrication devices. However, such devices are far too complex and expensive, so that they can only be used for larger systems.
  • the object of the invention is achieved by the features listed in the characterizing part of patent claim 1. It is ensured by a direct pressure oil line from the lubricating oil pump or a connection point of the main pressure line just behind the lubricating oil pump that the bearing points to be supplied are supplied immediately with the interposition of an idle-proof lubricating oil filter.
  • patent claim 3 ensure that the more distant bearing points are supplied by the direct pressure oil line only in the start-up phase, the oil supply being provided by the latter after the start-up and sufficient pressure in the main pressure line. This ensures that all bearing points are supplied with cooled and, if necessary, filtered oil during normal operation of the internal combustion engine. If there is a relatively small amount of oil flowing through the direct pressure oil line and the distant bearings to be supplied tolerate an oil that has been heated and not recooled according to the engine operation, the direct pressure oil line and the usual connecting line can be maintained throughout the operating time of the engine between the main pressure line and the bearing points.
  • the object of the invention is also achieved by the features of the characterizing part of claim 4. It is assumed that the oil can only flow back through the main pressure line when the bearing points are idle or safe to drain, but this is not possible due to the shut-off device.
  • the no-load or drain protection can be ensured by designing the branch lines from the main pressure line and their adjoining rooms to the bearing points in such a way that their highest point is higher than all other rooms in the oil circuit. Even if the connecting line from the main pressure oil line to the more distant bearings, e.g. B.
  • an exhaust gas turbocharger should have run empty over lower lying bearing points, the oil pressure when the shut-off valve is opened and the filled oil chambers of the pressure oil build-up in the connecting line will then take place just as quickly as would be the case via a direct pressure oil line.
  • 1 denotes an internal combustion engine which is only shown in outline and which has an oil sump 2 from which a lubricating oil pump 3 can draw in oil.
  • a throttle valve or shut-off element 5a denoted by 5
  • main pressure line 6 in which an oil cooler 7 and a filter device 8 are installed.
  • a connecting line 1 2 is also connected to the main pressure line 6 and leads to remote bearing points 14 of an exhaust gas turbocharger 15 via a changeover valve 13. From the remote bearing points 14 R leads ückflußtechnisch 16 in the oil sump 2.
  • the lubricating oil pump 3 is connected a direct pressure oil conduit 1 7 which chmierölfilter via an idle secure S 18 leading to the reversing valve. 13
  • the changeover valve 13 is designed so that pressure in the connecting line 12, namely in the area between the main pressure line 6 and the switching valve 13, switches the latter such that a connection between the connecting line and distant bearing points 14 takes place, while in the absence of pressure or a low pressure in the Connecting line, the switching valve 13 is switched to the switching position shown in the drawing, so that the connecting line is interrupted and the direct pressure oil line is connected to the distant bearing points.
  • the throttle valve or shut-off device is actuated by means of a servo cylinder 19, a piston 20 arranged inside the servo cylinder being acted upon by the pressure in the direct pressure oil line 17 on the one hand by a spring 21 and on the other hand via a control line 22, so that the throttle valve or shut-off device is depressurized or the lowest pressure in the direct pressure oil line is closed and opened with sufficient pressure in the pressure oil line.
  • the drawing also shows dash-dotted lines for 3 bearing points 10 of the crankshaft 11 Stub lines 9a are provided, which are arranged so that they have a higher point than the main pressure line with adjoining rooms as close as possible to the bearing points, so that the lubricating oil system is designed to be idle-proof when using these stub lines and using a shut-off valve, the direct pressure oil line 17 then being omitted can.
