Definitions

  • the invention has for its object to improve such an engine in terms of power-to-weight ratio and to enable the four-cycle operation of the engine operating without a valve train by a special control of the gas exchange.
  • the piston rod is expediently connected to the crankshaft by means of a ball joint, the outer joint shells of which are connected to two connecting rods running laterally past a cylinder, which in turn are mounted on the crankshaft.
  • the power transmission from the two pistons to the crankshaft can thus take place via two connecting rods, which support each other and which in no way hinder the rotation of the piston rod.
  • the connecting bore between the piston wall and the piston crown is used both for the intake of fresh gas and for the discharge of the exhaust gas by successively passing this connecting bore through the inlet opening and then the outlet opening of the cylinder.
  • at least two connecting bores start from each piston crown, one of which corresponds only to the inlet opening, the other only to the outlet opening of the cylinder depending on the piston rotation.
  • Each cylinder expediently has two inlet openings and two outlet openings.
  • the inlet openings as well as the outlet openings are arranged exactly opposite one another so that a compensation of the pressure forces can occur in the cylinder.
  • the position of the inlet and outlet openings results from the cross section in FIG. 2.
  • the cylinder 2 has two inlet openings 26 and 27 lying opposite one another and two outlet openings 28 and 29 lying opposite one another.
  • the inlet and outlet openings are also arranged on the cylinder 1 accordingly .
  • connection bores in the piston correspond depending on its stroke and rotary movement. These connecting bores extend from the piston wall to the piston head and are also arranged opposite one another, as is indicated in FIG.
  • the shape of the inlet and outlet openings in the cylinder wall is selected on the basis of design and fluid mechanics.
  • the diamond shape shown in the drawing allows the maximum opening cross section for the intake and exhaust with exact separation of the intake stroke from the exhaust stroke. In general, however, the opening hours between outlet and outlet are overlapped. In practice, the contour of the inlet and outlet openings will therefore differ from the shape of the rhombus.
  • a variant is indicated schematically by the dashed rectangle in the inlet and outlet openings 27 and 29.
  • the channels 30 and 32 can have a partition wall 30a or 32a running from the outside inwards.
  • This partition has the task of ensuring during the transition from the exhaust stroke to the intake stroke that the opposite gas flows interfere as little as possible.
  • This partition can of course be omitted if the number of channels in the piston is doubled, so that separate channels are available for intake on the one hand and for exhaust on the other.
  • the ball joint 15 does not necessarily have to be arranged between the two pistons 3 and 4. There is also the possibility of arranging it opposite from the cylinder head 6 and guiding the two connecting rods to the crankshaft 10 from there.
  • spark plugs there are also various options with regard to the positioning of the spark plugs.
  • This positioning has the advantage that the spark plugs are in the immediate vicinity of the main gas mass.
  • This ball roller guide is indicated in Fig. 3 by the reference numerals 36 and 37. It consists of two ball slides, each in a longitudinal slot running in the stroke direction of the cylinder housing are arranged and support the two connecting rods 11 and 12 transversely to the stroke direction. As a result, the piston seals are relieved of the usual transverse forces and can be optimally designed for their sealing function.
  • the channels 30 to 33 in the pistons are sealed off from the cylinder wall by sealing strips known per se, which are pressed resiliently against the cylinder wall.
