Definitions

  • the subject of this invention is internal combustion engine with heat regeneration system for regeneration of heat carried away together with exhaust gases.
  • both pistons move with the same frequency with a phase displacement and air is being pressed over between them.
  • heat is supplied from outside through the heater.
  • the nature of the internal combustion engine according to the invention consists in that the air being the charge of the engine is being compressed outside the working cylinder in a multi-stage compressor. Compression takes place in such a way that after it the air temperature is similar to ambient air temperature of the air being supplied to the feeding cylinder.
  • Said feeding cylinder is connected through a valve with a heat exchanger and then through the subsequent valve to the working cylinder.
  • Swept volume of said working cylinder is considerably greater than that of the feeding cylinder.
  • the motions of the piston in both cylinders are synchronized, the time of the motion of the feeding cylinder from the outer dead center to the inner dead center being considerably shorter than that of the analogous motion of the working cylinder.
  • the feeding cylinder is driven by a separate shaft connected to the main shaft by gear transmission, or directly by the main shaft by means of cams and push rod.
  • Air is being pressed over in one direction only from the feeding cylinder to the working cylinder through heat exchanger in a short time at the moment when the working piston in near to its inner dead center upon completion of its stroke. Pressing over can begin both when the working piston has not reached its dead center and when it has already reached and passed its dead center. Pressing over of cold air through the heat exchanger causes that the temperature of said air exceeds the temperature of the active heater and the air pressure exceeds the value resulting from the degree of volumetric changes. After the air has been pressed over and the valves have been closed there follows fuel injection and fuel combustion and there takes place the working stroke. Heat exchanger abstracts heat from exhaust gases leaving the engine and gives it up to the next portion of air being pressed over between the cylinders.
  • Piston of the working cylinder can perform one working stroke per one shaft revolution without the necessary troublesome scavenging of the cylinder.
  • An essential factor is the ratio of the volume of air before preliminary compression to the swept working cylinder volume.
  • Another essential factor is air pressure and air temperature after preliminary compression and the temperature of heat exchanger and the degree of volmnetric changes of gases which occur when air is being pressed over from the feeding cylinder to the working cylinder.
  • Still another essential factor is the moment when fuel injection takes place and the amount of fuel.
  • Engine control during operation is performed mainly by changing the amount of the injected fuel.
  • the described engine can also work as external combustion engine. In this case heat is being supplied to the engine through the heat exchanger only and it is obtained from combustion of fuel outside the engine.
  • the presented engine has been provided with a multi-stage compressor ⁇ with interstage coolers 2_connected through valve 3 to feeding cylinder 4, with piston 5 moving in it connected to the crankshaft 6.
  • Cylinder 4 through valves 7 and 9 , as well as heat exchanger 8 is connected to the working cylinder JO, wherein piston l ⁇ is moving connected to crankshaft 12.
  • Cylinder 10 has a fuel injector 13 . and exhaust valve J4 carrying away gases to exhaust passage 15 . connected to heat exchanger 8.
  • Operation of the engine according to the invention is as follows: Air after being compressed in compressor ⁇ and cooled down in coolers 2 flows through valve 3 to feeding cylinder 4. During this time in the working cylinder K) there is finishing the exhaust stage. At the moment when the piston 11 comes near to the inner dead center exhaust valve 14 is being closed valve 9 is being opened. Air from the feeding cylinder 4 is being quickly pressed over through valves 7 and 9 and heat exchanger 8. As a result, it is being heated and additionally compressed this being due to volumetric change when being pressing over, thus reaching temperature considerably exceeding that of the heat exchanger.
  • valve 9 Closing of valve 9 is followed by fuel injection from injector from injector 13, combustion and, next, the working stroke. Work is taken over by crankshaft 12.
  • exhaust valve 14 When piston H has reached the outer dead center exhaust valve 14 is being opened and exhaust gases flow to the duct 15, passing through heat exchanger 8. In said heat exchanger exhaust gases give up a past of heater to the next portion of air. Next exhaust gases flow through the passage to the turbo-compressor 1 and drive them.

Abstract

L'invention concerne un moteur à combustion interne dans lequel le cylindre de travail (4), fermé par une soupape (3), est relié au cylindre de travail (10), considérablement plus grand que le cylindre (4), par un conduit traversant un échangeur thermique (8) et une soupape (9). Le cylindre de travail (10) est pourvu d'une soupape d'échappement (14) permettant d'évacuer les gaz d'échappement vers un conduit d'échappement (15). Le mouvement du piston (5) dans le cylindre (4) est dépendant du mouvement du piston (11) dans le cylindre de travail (10).
