Abstract:
A combustion engine having a pair of two-chamber cylinders, in which double ended pistons are located and directed toward themselves oppositely by the angle 180° and compressed together via crankshafts consisting of two crank elements, which are linked rotationally backward by a spacer bearing. The compression is realized with the use of two connecting rod pairs, from which each connecting rod is linked on the one side to with one crank element, whereas the second connecting rod ends are linked to one of shafts, out of which each shaft is connected with one of pistons via a valve rod. In the middle of each cylinder's wall the outlet channel of compressed air is located as well as the outlet channel of products of combustion together with air. In the head of each cylinder and in the compartment the fuel injector, the water vapor injector and the ignition element are located.

Claim (Index 1):
A hydrogen engine which comprises the casing with the connecting-rod system and attached to it, closed from above with the head, cylinders, whereas inside each cylinder there is a two-sided reciprocating piston with sealing rings, which divides the internal space of the cylinder into two combustion chambers, with the valve rod mounted on one side, whose end comes out of the cylinder's chamber with the use of the linear slide bearing, situated in the lower compartment of the cylinder, moreover it comprises ignition elements and elements of the hydrogen fuel insertion into combustion chamber, and apart from that it has control systems of the hydrogen fuel injection, wherein, it has at least one pair of two-chamber cylinders fastened to the casting, in which two-sided reciprocating pistons are situated, while cylinders along with pistons are directed toward themselves by the angle 180\u00b0 on the rotation axis of the compressing them divided crankshaft, located on the casing, or they are in the position of the reciprocal location in a V-shape, however the crankshaft consists of two identical crank elements, which are directed toward themselves oppositely along their conjoint rotation axis and they are connected together rotationally backward around this axis with the help of the spacer bearing, moreover, the crankshaft has shafts on both sides which are taken out and they transfer the drive, and the compress function of the crankshaft is realized with the use of two identical connecting-rod pairs, out of which each connecting-rod of a given pair is rotationally linked by one of its end to one of counter-rotating craft elements of the crankshaft, whereas the other ends of this pair of connecting-rods are\n connected in an oscillating way with one of two transverse shafts, out of which each shaft is stiffly connected with one pair of conjugated pistons via the valve rod that is the perpendicular to it, apart from that, in the middle of each cylinder's wall, whose internal surface is covered with the anticorrosive coating, at least one outlet channel of compressed air and at least one outlet channel of products of combustion together with air are located, besides in the head of each cylinder and in its lower compartment at least one fuel injector at least one water vapor injector and at least one ignition element are located, what is more in the middle of each lower compartment the linear slide bearing is mounded, through which the valve rod is transferred, and the slide bearing is equipped from below with the annular sealing ring, above which on the remaining part of the slide bearing, between its wall and the surface of the valve rod craft, the lubricating micro slot is formed.
