Definitions

  • the present invention relates to an internal com ⁇ bustion engine finding application as a piston gazoline 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 aircrafts, as well as for water pumps, ge ⁇ nerators, hand tools, multistage piston compressors and others.
  • An internal combustion engine (1) con ⁇ sisting of a body in its upper hollow part performed as an internal cylindrical space whereas in its lower par ⁇ is shaped a crankshaft casing with the crankshaft posses- sing a journal and a connecting rod, the said connecting rod fitted in its lower end to the crankshaft.
  • the disadvantages of the known engine are as fol- lows: com ⁇ licated construction with large overall dimen ⁇ sions leading to great inertia of the moving parts which inertia is partialy balanced; complicated gas-distribu ⁇ ting mechanism and valve system, using lamilar (plate) and bevelseated (conical) valveS; long and complicated ways of the feeding and the discharging conduits lea ⁇ ding to an enhancement of the resistance of the air - fuel mixture and of the exhaust gases accordinglyjlo- were 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 worse ⁇ ned lubrication of the upper part of the inside cylin ⁇ drical space and of the working piston.
  • the task of the present invention is the elabora ⁇ tion 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 encreased specific power per unit of vo ⁇ lume and weight, as well as a normal lubrication of the upper part of the inside cylindrical space and of the working piston.
  • the internal combustion engine consisting of a body with a spark plug in its upper hollow part perfor ⁇ med aa an inside cylindrical space in which space is si ⁇ tuated the working piston whereas in its lower part is shaped the crankshaft casing with the crankshaft posses- sing a journal in lower position and a connecting rod bearing-mounted in its lower end to the crankshaft.
  • a com ⁇ pressor piston situated down of the cylindrical snace of the body, whereupon in the upper part of the body is sha- ped the intake port with a throttle valve, whereas be ⁇ low of the intake port is situated the exhaust port.
  • the working piston is elaborated as an one-piece body whose lower part having a larger diameter into which is put in. the compressor piston and whose upper part beneath the rings as a port, which port in the upper dead point is just in front of the intake port.
  • the exhaust port is situated upon the lower part of the working piston in lo ⁇ was dead point and the working piston is fitted diar ⁇ etri- cally opposite respectively to the both connecting rods suspended through the journals in upper position of the cranksha t.
  • the intake port shaped in the upper part of the body is foreseen also an intake valve and to the exhaust port is foreseen an exhaust valve, whereupon the port in .the upper part with a smaller diameter of the working piston is situated over the rings beneath the foreseen intake valve in the body.
  • the advantages of the internal combustion engine ac ⁇ cording to the invention are as follows: it operates as a two-stroke engine without need of oil addition into the fu ⁇ el for lubricating the details in the internal cylindrical space; there is no need of valve system and gas-distribu ⁇ tion mechanism; the engine enables from 3 to 6 time the en ⁇ hancemen of the specific power per unit of volume and weight of the construction; during the pistons operation is used, a counterstroke motion offering favourable condi- tions for relieving the dynamical balancing of the moving details 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.
  • ⁇ igure 2 shows a cross-section of the engine while the working cylinder is in a moment of expansion/compres ⁇ sion of the fuel-air mixture.
  • figure 3 shows a cross-section of the engine in the lower dead point.
  • iigure 4 shows a cross-section of the engine illus ⁇ trating application of intake and exhaust valve.
  • the internal combustion engine according to the invention is built by: a body 1 in whose upper part is situated the working piston r>_ con ⁇ nected through two connecting rods 3 and 4 and the res ⁇ pective journals 15 and 16 in the upper position of the crankshaft 5 situated in the lower part of the body 1 shaped as a crankshaft casing 11. Between both journals 15 and 16 in lower position is situated a third journal 14 of the crankshaft 5 to which third journal 14 is fit- ted the connecting rod 6 connected to the compressor pis ⁇ ton- 7 situated inside of the space of the lower part 12 of the working piston 2, which part 12 has a larger di ⁇ ameter.
  • the upper part 13 of the working piston 2 which part 13 has a smaller diameter and both parts together form a body wherein the upper part 13 in its upper end beneath the rings 17, has a port 19 situated in the upper dead point of the engine in front of the intake port 8 with throttle valve 18.As it is shown on figure 4, the port 22 is situated beneath the intake valve 20.
  • the spark plug 10 aperture In the upper part of the body 1 stands the spark plug 10 aperture.
  • the engine is operating as follows: As it is shown on figure 1 the working piston 2 of the engine is in the upper dead point, while the compres ⁇ sor piston 7 is in the lower dead point 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 2 0) 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. All this fuel-air mixture is compressed as a result of the displacement of the working piston 2 downward to the lo- were dead point and the respective displacement of the com ⁇ pressor piston 7 toward the upper dead point, according to the figure 2.
  • the high efficient performance of the engine ac ⁇ cording to the invention is achieved owing to the coor ⁇ dination of a great number of constructive and physical factors such as: the reduced lenght of the suction track; the absence of unnecessary constructive spaces and the double space resulting from the countersense motion of the working piston 2 and the compressor piston 7, enab ⁇ ling the achievement of an exclusively favourable char ⁇ ging of the engine with the fuel-air mixture.
  • the high- velocity under pressure assing 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 eva ⁇ oration 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 combus ⁇ tion 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 mis- sing in the known similar engines, enable to be achie ⁇ ved an extrin&y high power per litre of displacement and efficiency, other conditions such as volume,weight, tur ⁇ bo-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.
