Definitions

  • the invention relates to the field of internal combustion engines and can be used as the engine of a car, tractor and other machines.
  • the technical result is achieved in the method of operation of an internal combustion engine with conversion into useful work of heat generated during combustion in cylinders, in which working cycles based on the expansion of gaseous products of combustion alternate with working cycles based on the expansion of vapor of the liquefied gas cooler.
  • a cooler gas for example, liquid nitrogen, liquid hydrogen or gas from liquefied hydrocarbons can be used, the latter, in turn, can be used simultaneously as fuel, and after the cooling cycle, the heated gas is supplied to the cylinders as fuel.
  • SUBSTITUTE SHEET (RULE 26) As is known, the transition of a substance from a liquid state of aggregation to a gaseous state is accompanied by heat absorption proportional to the mass of the substance and its specific heat of vaporization. Also, heat absorption occurs upon subsequent heating of cold gas vapors (for nitrogen the initial temperature is -196 0 C) to the temperature of the combustion products remaining in the cylinder (average temperature of the latter about 800 0 C).
  • the gas density is many times lower than the density of the liquid (for example, the density of liquid nitrogen is 808 kg / m, and the density of gaseous is 1.25 kg / m 3 under normal conditions), then excess gas occurs in a small closed volume of the combustion chamber pressure that acts on the piston, doing useful work.
  • the operation scheme of an engine constructed according to such a scheme and equipped with an injection system for a liquefied gas cooler can be as follows: 1st cycle - intake of a combustible mixture; 2nd cycle - compression of the combustible mixture;
  • 4th cycle the release of gaseous products of combustion; 5th step - injection of a cooler gas into a hot combustion chamber, its evaporation and stroke (cooling of the combustion chamber occurs); 6th step - release of gas cooler.
  • this principle of operation can be called an alternation of “hot” (from the 1st to the 4th) and “cold” (from the 5th to the 6th) measures.
  • By adjusting (possibly using an electronic control system) the ratio of fuel and refrigerant consumption it will be possible to achieve the optimal heat balance of the internal combustion engine in a wide range of loads and external temperatures without the use of a traditional liquid cooling system.
  • the proposed engine version has two piston strokes for every three revolutions of the crankshaft (2 cycles out of 6) against one working stroke per two revolutions of the crankshaft (1 cycle out of 4) as in a conventional internal combustion engine, which makes it possible to obtain a reduction engine weight per unit of power, as well as saving hydrocarbon fuel, since combustion occurs only in one out of six cycles.
  • the fuel itself is used as a cooler gas (for example, liquefied methane or liquefied hydrogen)
  • a cooler gas for example, liquefied methane or liquefied hydrogen
  • the fumes of the cooler gas must be released through a separate valve not into the atmosphere, but into the mixing chamber, from where mixes with air (oxygen or another oxidizing agent) to feed it again into the cylinders as fuel.

Abstract

L'invention concerne des moteurs à combustion interne et vise à augmenter le rendement, réduire le poids du moteur par unité de puissance et améliorer ces caractéristiques en termes d'environnement. Selon l'invention, dans le procédé de fonctionnement du moteur les temps de combustion dans un ordre quelconque sont alternés avec les temps de refroidissement basés sur la dilatation des vapeurs d'un gaz de refroidissement liquéfié. Par analogie avec un moteur à quatre temps commun, après le quatrième temps d'échappement on effectue l'injection de gaz de refroidissement liquéfié qui, en s'évaporant, refroidit la chambre de combustion et effectue en même temps une course de travail supplémentaire. Certains gaz liquéfiés tels que l'hydrogène ou les hydrocarbures peuvent s'utiliser simultanément en tant que carburant et en tant qu'agent caloporteur. Dans ce cas, après la course de refroidissement, le gaz chauffé (mélangé à de l'air ou à de l'oxygène) est réinjecté de nouveau dans les cylindres mais cette fois-ci en tant que carburant.
