Definitions

  • the present invention relates to an internal combustion engine finding application as a piston gasoline or diesel engine with supercharging for all kinds of transportation facilities such as motor vehicles, motor cycles, motor-boats, racing cars, industrial trucks, light-weight aircraft, as well as for water pumps, generators, hand tools, multistage piston compressors and others.
  • An internal combustion engine is known down GB-A-2 149 006 , consisting of a body in its upper hollow part performed as an internal cylindrical space whereas in its lower part is shaped a crankshaft casing with the crankshaft possessing a journal and a connecting rod,the said connecting rod fitted in its lower end to the crankshaft.
  • a compressor piston situated in a lower part of the cylindrical space whereas in an upper part of the cylindrical space is situated the working piston connected through a pipe to the compressor piston.
  • the working piston connected through a pipe to the compressor piston.
  • two horizontal valve plates forming a conduit connected through a throttle valve to the intake port.
  • Both valve plates have respectively an intake and an outlet port, symmetricaly disposed on both sides of the pipe between the pistons.
  • the outlet port from the one valve plate and the intake port from the other valve plate are connected through a conduit and an intermediate chamber to an intake valve in the uppermost part of the cylindrical space.
  • Next to the intake valve is situated an outlet valve whose port is also connected through a conduit.
  • the disadvantages of the known engine are as follows: complicated construction with large overall dimensions leading to great inertia of the moving parts which inertia is partialy balanced; complicated gas-distributing mechanism and valve system, using lamilar (plate) and bevelseated (conical) valves. long and complicated ways of the feeding and the discharging conduits leading to an enhancement of the resistance of the air-fuel mixture and of the exhaust gases accordingly;lower specific power per unit of working volume and weight having in mind that the engine is operating as a four-stroke internal combustion engine; as well as a worsened lubrication of the upper part of the inside cylindrical space and of the working piston.
  • 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 all dimensions, a simplified gas-distribution mechanism using short and direct feeding and discharging ways of conduits, with increased specific power per unit of volume and weight, as well as a normal lubrication of the upper part of the inside cylindrical space and of the working piston.
  • the advantages of the internal combustion engine according to the invention are as follows: it operates as a two-stroke engine with no need for oil to be added into the fuel for lubricating the parts in the internal cylindrical space; there is no need of valve system and gas-distribution mechanism; the engine enables from 3 to 6 times the enhancement of the specific power per unit of volume and weight of the construction; during the pistons operation a counterstroke motion is used offering favourable conditions for relieving the dynamical balancing of the moving parts as well as a straightflow scavenging and charging of the combustion chamber.
  • Figure 1 shows a cross-section of the engine in the upper dead point 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 fuel-air mixture.
  • Figure 3 shows a cross-section of the engine in the B D C.
  • Figure 4 shows a cross-section of the engine illustrating application of intake and exhaust valve.
  • the internal combustion engine consists of an engine block (1) having a hollow cylindrical space therein,said cylindrical space comprising an upper cylinder and a lower cylinder having a larger diameter than the upper cylinder,the lower end of said engine block being shaped into a casing (11) containing a crankshaft (5),said crankshaft carrying the big ends of three conrods (3, 4, 6) on journals spaced along said crankshaft,the two outer conrods (3, 4) being journaled on crankshaft eccentrics (15, 16) which are axially in line with each other,the central conrod (6) being journaled on a crankshaft eccentric (14) diametrically opposite to the other eccentrics (15, 16) with respect to the crankshaft axis, the little ends of the two outer conrods being attached to a hollow working piston (2) having an upper part (13), the outer diameter of which is matched to the upper cilinder, and a lower part (12), the outer diameter of which is matched to lower
  • the engine operates as follows:
  • the working piston (2) of the engine is in the TDC, while the compressor piston (7) is in the BDC and owing to the vacuum created in the inside space of the working piston (2) a suction of fuel-air mixture is produced by the intake port (8) ( or as it is shown on figure 4 by the intake valve (20) ) of the body 1 and by the port (19) (or as it is shown on figure 4 by the port (22)) of the working piston (2).
  • the highly efficient performance of the engine according to the invention is achieved owing to the coordination of a great number of constructive and physical factors such as: the reduced length of the suction track; the absence of useless constructive spaces and the double space resulting from the countersense motion of the working piston (2) and the compressor piston (7), enabling the achievement of an exclusively favourable charging of the engine with the fuel-air mixture.
  • the high-velocity under pressure passing of the fuel-air mixture through the small port (19)(or through the port (22) as it is shown on figure 4 ) of the working piston (2) provokes an additional homogenizing, atomization and evaporation of the mixture.All this allows the achievement of a full economical and ecologicaly pure combustion process.
  • the straight-flow and the vortex-flow motion of the fuel-air mixture enables the complete scavenging of the burnt gases and at the same moment the cooling of the spark plug and its safe contacting with the combustion mixture.
  • the absence of valves, springs, camshafts, the utilisation of the classical two-stroke working principle,the supercharging with the fuel-air mixture as well as the abovementioned advantages which are missing in the known similar engines, enable an extremely high power per litre of displacement and efficiency to be achieved, other conditions such as volume,weight, turbo-compressors, computer control, fuel injection etc. being equal.

Abstract

Par ses éléments techniques, sa cinématique et sa technologie ainsi que sa construction, le moteur à combustion interne se rapporte aux moteurs de type vilebrequin-piston. Son champ d'application englobe la gamme entière de moteurs à combustion interne mais s'adapte notamment aux voitures de course, ce moteur étant destiné aux Formules Un. L'invention se caractérise en ce que le moteur est un moteur à deux temps, mais fonctionne à l'aide de carburant pur sans adjonction d'huile, la lubrification étant forcée comme pour tous les moteurs à quatre temps bien connus, et est doté d'une faculté de surcompression inhérente qui permet son emploi comme moteur à essence ou diesel.
