Definitions

  • the present invention relates to an internal combustion engine finding application as a piston gasoline or diesel engine adapted for setting in motion all kinds of transportation facilities such as : motor vehicles, trucks, tractors, motorcycles, motor-boats, racing cars, light-weight aircrafts, as well as water pumps, generators, hand tools , multistage piston compressors and others.
  • An internal combustion engine consisting of a body in its upper hollow part performed as an internal cylindrical space whereas in its lower part is shaped a casing containing a crankshaft possessing three eccentric journals as the two end journals are opposites to the central journal, said crankshaft has three connecting rods and their lower ends are journaled on the crankshaft eccentrics.
  • a long hollow piston having a internal cylindrical space whereas to the upper end of the central connecting rod is connected a little piston situated within the internal cylindrical space of the long piston, as in the upper part of the body is shaped a combustion chamber where a sparking plug is situated, and the working piston is performed with an upper part, the diameter of which is smaller, and with a lower part having a greater diameter , the lower part contains the compressor piston journaled through a connecting rod and said compressor piston is diametrically opposite to the working piston journaled through two conrods that are suspended through journals to the crankshaft as between the face of the compressor piston and the inner cylindrical part of the working piston it is formed a variable inner space , the upper part of the working piston, below the segments , has a port which at the TDC is situated a front of the inlet port whereas at the BDC the exhaust port is situated above the lower part of the working piston whereat the working piston is journaled diametrically opposite to the compressor piston through two conrods
  • the task of the present invention is the elaboration of an internal combustion engine possessing to a large degree a simplified construction with reduced over dimensions, a simplified and light crank mechanism allowing a facilitated and technological manufacturing of multicylinder variants of internal combustion engines.
  • this task is achieved with a internal combustion engine consisting of a body, the upper part of which contains a working piston connected through one or two conrods in corresponding one or two journals to a crankshaft situated in the lower part of the body , said lower part is shaped as a casing whereas the compressor piston is situated within the inner space of the lower part of the working piston having a greater diameter and the compressor piston is fixed through a bar to the lower or upper part of the body as above the lower part of the working piston is a this part of the working piston which has a smaller diameter and it has an inner transfer port as the both parts form a common body and the inner transfer port is disposed below the intake valve, and between inner cylindrical part of the working piston and compressor piston face it is formed a variable inner space through which the sucking and supercharge of the air-fuel mixture is taking place, in the upper part of the body, below inlet port, is disposed an exhaust port which is above the lower part of the working piston at its BDC.
  • the advantages of the internal combustion engine are as follows : it has a light and simplified crank mechanism and this allows manufacturing of a internal combustion engine with reduced weight and over dimensions and with bette r efficiency because of less number of the fric tion details.
  • Figure 1 shows a cross -section of the engine in the upper dead centre of the working cylinder
  • Figure 2 shows a cross-section of the engine while the working cylinder is in a moment of expansion (compression) of the air-fuel mixture
  • Figure 3 shows a cross-section of the engine in the bottom dead centre.
  • Figure 4 represents a cross-section of the engine showing the use of two connecting rods and attaching the compressor piston to the lower part of the engine body.
  • the internal combu stion engine is built by a body / 1 / in its upper part is placed a working piston 111 connected through a conrod 1 31 to a corresponding Journal /14/ on the crankshaft /21/ or as it is shown on the Figure 4 - with two connecting rods /4/ and 15/ to the correspondingjournals / 15/ and / 16/ on the crankshaft placed in the lower part of the body HI, said lower part is shaped as a casing /l 1/ whereas the compressor piston 171 contained within the space of the lower part /12/ of the working piston 11/ having a greater diameter is fixed through a bar 16/ to the upper part of the body /l/, or as it Is shown on Figure 4 said compressor piston is fixed through the support IS/ to the lower part of the body /l/ while above the lower part /12/ it is the upper part /13/ of the working piston 11/ , the diameter of which is smaller and it has a inner transfer port
  • the engine is operating as follows:
  • the working piston 111 of the engine is in the TDC while the compressor piston 171 is in the TDC and owing to the vacuum created in the inside space of the working piston 121 a suction of air- fuel mixture is produced by the intake port 191. All this air-fuel mixture is compressed in the inside space as a result of the displacement of the working piston 111 downwards to the BDC, according to the Figure 2.
  • the compressed air- fuel mixtu re in the inner space flows through the port / 18/ into the combustion chamber representing the space formed between the u pper part of the body 1 1 1 and the working piston 12 / itself.
  • the air-fuel mixture fallen into the combustion chamber of the engine is subjected to compression by the displacement of the working piston / 2 / towards the TDC and when reaching it, according to the Figure 1 , the mixture is ignited by the sparking plug / 1 7/ and pushing the working piston downwards to the crankshaft it is doing the working stroke.
  • the working piston 12 / At the opening of the exhaust port / 10/ , according to the Figure 3 , by the working piston 12 / , the burned gases flow out through the exhaust port / I O/ and in the next moment the combustion chamber of the engine is filled with a fresh air-fuel mixture entering through the port / 20 / from the inner space through the port / 18 / . In this way is accomplished a straightflow and a vortex- flow high-performance scavenging of the combustion chamber and afterwards the above described working proc ess is cyclically and manifold repeated , doing the operation of the engine.
  • the high -efficiency operation of the engine is achieved owing to the coordination of a series of constructive and physical factors such as: lack of casing suction and compressing; a reduced length of the suction track; a absence of useless constructive spaces; a simplified crank mechanism and less nu mber of friction details, as well as the operation as a double- stroke engine with pure fuel without oil.

Abstract

Par ses éléments techniques, sa cinématique, sa technologie et sa construction, le moteur à combustion interne de la présente invention s'apparente aux moteurs de type à vilebrequin/piston. Le champ d'application dudit moteur couvre toute la gamme d'utilisation des moteurs à combustion interne, mais ce moteur convient particulièrement aux voitures de course, y compris les voitures de Formule Un. Ledit moteur a la caractéristique d'être un moteur à deux temps fonctionnant au carburant pur sans adjonction d'huile, ce qui rend la lubrification nécessaire comme pour les moteurs à quatre temps bien connus. Ce type de moteur peut fonctionner à l'essence ou au gazole.
