Definitions

  • a PROHPI Engine makes, in its basic form, use of one cylindrical piston which both reciprocates and rotates.
  • Essential element is a sine wave alike piston top which moves against a sine wave alike formed cylinder head.
  • Maximum compression is generated when the wave crests of the piston fit within the wave-hollows in the cylinder head (figure 1A where [1] depicts the cylinder head top and [2] depicts the piston top).
  • Maximum expansion occurs when wave crests of the piston move over the wave crests of the cylinder head (figure 1B).
  • the waveforms of the piston and of the cylinder head have a constant amplitude and a constant shape over their full radius in such a way that they can maintain an uninterrupted radial line contact between piston and head at every angle of rotation of the piston for every full wave.
  • Deviations from a pure sinusoidal wave form result in non-infinite accelerations of the piston following the cylinder head and in a non-infinite compression ratio.
  • One or more channels in the wave crests of the cylinder head allow the compressed air or air / fuel mixture to flow from the compression chamber into the combustion and expansion chamber.
  • Figure 2A to 2H shows a representation of the different stadiums of a piston - cylinder head configuration during a four stroke engine cycle.
  • the centre part of the piston is taken out [5], fitting around a cylindrical centre pylon on the cylinder head [6] or is cylindrically extended [7], fitting in a cylindrical hollow within the cylinder head [8] (see figures 3A and 3B ).
  • valve-less ports For breathing, that is for exhaust gases to escape during the exhaust part of the cycle and for air or air - fuel intake for the intake cycle, valve-less ports can be used. Those ports can be placed within the outer cylinder wall or within a possible centre cylinder head pylon, or in a combination thereof. For a four stroke configuration, ports can also be placed within the sine wave alike top surface of the cylinder head, or in a combination of the three options.
  • the intake ports enable filling of the intake chamber during the intake cycle when the piston moves away from the cylinder head ( Figure 2A to 2D ).
  • the next wave in the piston top compresses the air or air - fuel mixture when the piston moves again towards the cylinder head ( Figure 2E to 2G ).
  • Figure 2H maximum compression
  • the compressed air or air - fuel mixture is pressed through the already mentioned channel or channels ( Figure 2 , [9]) to the combustion and expansion chambers, in parallel of being ignited or fuel being injected and ignited (gasoline or gas fuelled engines) or self ignited (e.g. diesel fuelled engines).
  • the heated and expanded gas mixture pushes the piston away again from the cylinder head while rollers guide the piston to follow its hopping and rotating motion path and transfer the pushing force on the piston into a rotating movement ( Figure 4 ).
  • the exhaust port comes free and subsequent closure of the combustion chamber by the next wave of the piston pushes the exhaust gasses out of the chamber.
  • exhaust and intake ports open closely around the position where the piston is in its lower dead centre. Exhaust gasses start to escape just before the lower dead centre ( Figure 2D ). Subsequently, air or an air - fuel mixture is forced into the chambers between the piston and the cylinder head, e.g. by the downward movement of the piston, meanwhile displacing the last bit of the exhaust gasses which escape in parallel. During maximum compression, the compressed air or the air - fuel mixture is also pressed through the channel like connections between adjacent chambers formed by the wave forms of the piston and cylinder head.
  • FIG. 5 shows a possible mechanical solution for the transfer of the rotational motion from the piston to the main shaft.
  • the PROHPI Engine can be used for the following applications:
  • PROHPI engine generators and other stationary and non-stationary power units, e.g. to drive fans, compressors or pumps, for light hand tooling like chain saws, mowers etc., for reciprocating tooling like pile or driving sheet drivers and jack hammers, as power source for fan, rotor or propeller aircraft or hover craft and for all general automotive, train, nautical or other mobile primary drive lines and models thereof or range extenders or apu's (auxiliary power units) there for.
  • stationary and non-stationary power units e.g. to drive fans, compressors or pumps, for light hand tooling like chain saws, mowers etc., for reciprocating tooling like pile or driving sheet drivers and jack hammers, as power source for fan, rotor or propeller aircraft or hover craft and for all general automotive, train, nautical or other mobile primary drive lines and models thereof or range extenders or apu's (auxiliary power units) there for.
