Definitions
- Engine Assembly comprising an internal combustion engine and a steam engine.
- the present invention refers to an engine assembly comprising an internal combustion engine and a steam engine connected to a driving assembly e.g. by a common driving axle, and a heat exchanger by which the heat losses, as exhaust gases and/or cooling water, from the internal combustion engine is utilized for generation of steam to the steam engine.
- the object of the invention is to accomplish an engine assembly of the introductorily mentioned type, with essentially smaller dimensions and weight and which optimizes the flex ⁇ ibility which is built-in in a rational steam engine system.
- the invention is based on the utilization of a steam buffer of that type which is described in detail in an application filed together with this application, called “Steam buffer for a steam engine plant ", to which is referred regarding details about the steam buffer.
- This steam buffer is equipped with a high temperature connection for steam, preferably with the temperature 500 °C and the pressure 250 bar, and a low temperature connection for feed water and therebe ⁇ tween a solid heat exchanging material with a large number of pressure resistant flow channels with a hydraulic diameter less than 0.5 mm for the steam and feed water between the two con ⁇ nections.
- the engine assembly according to the invention is specially suitable for propulsion of heavy vehicles like trucks and long freight trains or boats, and especially boats that require high power output for short periods of time in order to obtain planing velocity rapidly.
- the steam engine 7 is by a transmission 22 connected to a driving shaft 23, which is connected with the crankshaft of the engine 1.
- the diesel engine 1 is dimensioned to operate at full load at normal driving cycles and drive the drive shaft 23, to which even the steam engine 7 is connected.
- the steam engine is dimensioned to operate at low loads at normal driving cycles. Both engines will then operate at almost their optimum efficiency.
- the steam to the steam engine 7 is generated in the heat exchanger 4 in an amount that is slightly larger than what is required at normal driving cycles.
- the excess steam is fed to the steam buffer 20, and the feed water in the steam buffer is pressed back to the pipe 14 and then further to the pressure vessel 21, where the gas cushion is compressed.
- a control valve 24 will be opened in the pipe 6 to the steam engine 7 from a position corresponding to low load to a position corresponding to full load. Steam will then flow from the steam buffer 20 to the steam engine 7 with the highest or a required power capacity.
- the diesel engine be designed to give 70 kW at 100 % load and the steam engine to give 30 kW at 5 % load.
- both engines will work at almost optimal effi ⁇ ciency and simultaneously a continuous charging of the steam buffer will take place if not fully charged.
- the engine assembly can, if the steam buffer is charged, give 670 kW instantaneously. For how long time it is possible to obtain this power depends of course on the size of the steam buffer, which as mentioned can have an energy density of 500 kJ/kg.
- the invention is of course not restricted to this shown and described example but can be modified in several ways within the scope of the inventive idea defined by the claims.
- the two engines can for instance be connected to different drive shafts of some kind of driving assem ⁇ bly.
- a small steam generator can of course be connected to the steam pipe 6 for gener ⁇ ation of steam as complement to the heat exchanger 4, if required , e.g. to keep the steam system warm when there is freezing hazard.
- the steam buffer has a very high energy density of 500 kJ kg , and with a proper heat insulation there will be possibilities to store heat energy for long time periods.
