Definitions

  • the invention relates to two kinds of combustion engines, nameable combi-stroke and combi-shaft engine; in a combi-stroke engine, the smallest volume of the combustion chamber between the pistons is attained, when fast- or slow moving piston or pistons has or have past the highest dead point; in a combi-shaft engine the piston motion is transformed into rotation by means of a crank-shaft combination.
  • combi-stroke engines of which the graphical rendering is shown in the figures 1 and 2. They distinguish themselves of combi-stroke engines as described in the Dutch application nr. 7807179 by the position of the crank-shafts, which is changed in this way, that the smallest volume of the combustion chamber is attained, after the slow moving piston(s) has (have) past the highest dead point.
  • crank-shaft in which one or more crank-shafts can be considered as crank or cranks for a secondary crank-shaft.
  • Fig.3 shows such a combi-shaft in outline
  • AB is the crank of the primary crank-shaft, rotating around point B
  • BC is the crank of the secondary crank-shaft, rotating in the same time and direction as AB around point C.
  • a piston with connecting-rod to point A will make four strokes during one rotation of BC.
  • Fig. 4 gives a graphical representation of the piston motion, brought about by every part of the crank-shaft and in full line the addition of the two, which represents the total piston travel. Considering the figures, it is obvious that the almost smallest volume of the combustion chamber in both types of engines changes less than in normal four-stroke engines during some time and that the expansion proportion is bigger-as the compression proportion.
  • crank-shafts can be constructed e.g. to be employed in two-stroke engines (se fig. 6) or in order to get rectilinear motion of a connecting-rod (see fig. 7).
  • fig. 8 One way of carrying out the invention concerning combi-shaft is drawn in fig. 8, showing a perspective view of a combi-shaft; fig. 8a is a side view in cross section and fig 8b is a front view of the connection between primary and secondary crank-shaft by means of toothed wheels.
  • AB and BC are corresponding to AB and BC in fig. 3.
  • any conbistroke engine has been drawn in outline; 1 is the inlet (under pressure e.g. by a turbine); 2 fuel injection; 3 inlet valve; 4 sparkle; 5 exhaust holes, circularly in the cylinder-wall; 6 two-stroke crank-shaft; 7 four-stroke crank-shaft; 8 connecting toothed wheel; 9 shaft.
