Definitions

  • the invention relates to a drive device having an internal combustion engine and a steam turbine, which is driven by utilizing the waste heat of the internal combustion engine, and with a gear unit 'which connects the steam turbine to the crankshaft of the internal combustion engine which rotates more slowly than the steam turbine.
  • Such combinations of internal combustion engines with devices for utilizing the waste heat of the internal combustion engine have the purpose of achieving the highest possible proportion of mechanical or electrical energy when converting the fuel.
  • This objective even applies to systems that serve, on the one hand, to supply mechanical energy that is taken from the crankshaft, and on the other hand to supply thermal energy for heating purposes.
  • the only problem is to increase the shaft power of the motor without uneconomically increasing the construction effort for the system.
  • the invention achieves a substantial reduction in the structural outlay in that the steam turbine is used to drive units which are driven in direct dependence on the engine speed. This makes sense if such units, like the steam turbine itself, have a considerably higher speed than the internal combustion engine active compound is derived to the crankshaft of the internal combustion engine stationary rinsing or Aufladegebl-äse to the incineration • motor. ' . *
  • the design of the unit driven by the steam turbine as a flushing fan results in two-stroke engines. These already have a transmission for driving the flushing fan, into which, according to the invention, the drive energy coming from the steam turbine can be introduced on the fan side .
  • a similar gearbox has four-stroke engines with mechanical supercharging, in which the supercharger is the unit driven by the steam turbine.
  • the steam turbine is to be uncoupled from the reduction gear so that the internal combustion engine, which now operates the flushing or supercharging fan, unnecessarily the drive of the steam turbine is loaded.
  • the consumers connected to the internal combustion engine are suddenly switched off, not only should further drive of the crankshaft by the steam turbine, but also high-speed idling of the steam turbine itself be avoided, which is why measures must be taken to prevent the steam driving the turbine for a short time redirect, e.g. through a quick-closing valve.
  • the transmission which connects the crankshaft to the blower is optimally used when the steam turbine provides approximately twice the blower output. Care must therefore be taken to ensure that a high degree of utilization of the waste heat of the internal combustion engine is achieved in the device according to the invention, for which a number of constructive proposals are made, which will subsequently be explained together with two exemplary embodiments of the invention.
  • FIGS. 3-5 show a cross section through the exhaust manifold 7 and two variants for the associated longitudinal cross section in the region of the separating joints the same.
  • Resonance damper serves to suppress certain interference frequencies of the exhaust noise.
  • the cooling system of the internal combustion engine 1 in the steam turbine cycle, so that the heat transfer medium is also the cooling medium of the engine.
  • the feed water pump not shown, is arranged between the engine cooling chambers and a first exhaust gas heat exchanger. It is also possible to use so-called hot cooling.
  • a booster pump not shown, is used between the low pressure rich in the cooling rooms of the internal combustion engine 1 and the high pressure area between the internal combustion engine 1 and the outlet of the heat transfer medium from the steam turbine 3 turned on.
  • the internal combustion engine 1 is used to drive another heat engine, for example a high-pressure compressor
  • the cooling heat of at least the high-pressure stages of the compressor in the circuit of the heat carrier can also be used.
  • the power of the steam turbine 3 is transferred to the crankshaft 12 by means of a reduction gear 2, since the speeds of the steam turbine 3 significantly exceed those of the internal combustion engine.
  • a reduction gear 2 is necessary anyway in order to bring an additional unit to a number of revolutions which exceeds that of the internal combustion engine by about ten times . 5
  • the internal combustion engine 1 is a two-stroke engine
  • the flushing fan forms such an assembly 11; if it is a four-stroke engine, the same conditions apply to a charging fan for mechanical charging.
  • the same mechanism can thus be used to advertising, the performance of the steam turbine 3 transmitted to the crankshaft 12 to be driven • or a rinsing or supercharger of the crankshaft 12 from.
  • a valve 14 is provided which can interrupt the steam flow to the steam turbine 3 and discharge the steam to an emergency cooler (not shown).
  • the exhaust manifold parts are provided on the outside with an insulation 19 which, after assembly, also includes the flanges 16 and the exhaust pipe (not shown).

Abstract

Une turbine à vapeur (3) est entraînée par les pertes de chaleur d'un moteur à combustion (1). Pour relier l'arbre de la turbine à vapeur au vilebrequin (12) du moteur à combustion qui tourne plus lentement, on utilise un mécanisme d'entraînement (2) qui sert à entraîner un compresseur de charge (11) du moteur à combustion (1) par l'intermédiaire du vilebrequin.
