Abstract: 1. Multiple circular slider crank reciprocating piston internal combustion engine with a plurality of circular sliders, comprising a crank mechanism and circular sliders, including cylindrical housing, cylinder heads, cylinders, pistons, circular sliders and a flywheel; fuel supply system; lubrication system; cooling system, characterized in that the engine has a sliding cavity in the cylindrical housing wherein balancing sliders of dynamic counterweight are fitted in said sliding cavity; at least three circular sliders are provided and combined into one piece, using locking pins, wherein the phase difference of two adjacent sliders is 180 degree C; all circular sliders are rotatably fitted correspondingly in piston holes and in the balancing sliders of dynamic counterweight and all of said circular sliders are mounted on a crankshaft. 2. Engine of Claim 1, characterized in that said comprising two cylinders (10, 11) mutually parallel and H-shape arrangement; a sliding guide (14) has a shape of cylindrical recess between two cylinders and perpendicular to them; pistons (15, 16) are double-acting; balancing slider of dynamic counterweight (25) has a cylindrical form, corresponding to the shape of the sliding guide; holes (22, 27) are arranged in the middle of each piston and balancing slider of dynamic counterweight; and the central axis of the crankshaft (30) passes through the cylinder middle and perpendicular to the central axes of cylinders and sliding guide. 3. Engine of Claim 1, characterized in that it is a five-cylinder engine, wherein the cylinders are arranged as two parallel row of cylinders; a sliding guide is a short cylinder, arranged between two parallel row of cylinders and perpendicular to two cylinders, wherein two cylinders and the sliding guide form H-( configuration and piston are double-acting; balancing slider of dynamic counterweight is one-way acting piston; the holes are arranged in the middle of each double-acting pistons and at one end of the one-way acting piston; and the central axis of the crankshaft passes through the cylinder middle and perpendicular to the central axes of cylinders and sliding guide. 4. Engine of Claim 1, characterized in that it is a six cylinder engine, wherein the cylinders are arranged as two parallel row of cylinders; sliding guides are short cylinders, arranged correspondingly on both sides of two parallel row of cylinders and perpendicular to two parallel row of cylinders wherein two cylinders and the sliding guide form H-( configuration and the piston are double-acting; balancing sliders of dynamic counterweight are one way-acting pistons; holes are arranged in the middle of each piston and at one end of the balancing sliders of dynamic counterweight; and the central axis of the crankshaft passes through the cylinder middle and perpendicular to the central axes of cylinders and sliding guide. 5. Engine of Claim 1, characterized in that the cylinders are two short cylinders (52, 53), arranged parallel; the sliding guide (53) is a short cylinder and arranged between two cylinders and perpendicular to two cylinders, wherein the cylinders and said sliding guide form V configuration; pistons and balancing sliders of dynamic counterweight are one-way acting pistons; holes (59) are arranged at one end of each unilateral-acting pistons; and the central axis of the crankshaft passes through the bottom portion of the cylinders and perpendicular to the cylinders and to the sliding guides. 6. Engines of any preceding Claims, characterized in that circular blocks of sliders (37, 38, 39) are plain cylinders, having similar outer diameter and eccentricity of holes (40). 7. Engine of Claim 6, characterized in that the hole (40) in circular sliders has the eccentricity equal to the radius of the crankshaft pin (30). 8. Engine of Claim 6, characterized in that the pin (31) of the crankshaft pin (30) is arranged between main journals (32, 33) along the central axis. 9. Engine of Claim 6, characterized in that circular block of sliders (38), mounted in the sliding guide of the dynamic counterweight has an axial width two times greater than the axial width of the circular blocks of sliding (37, 39) arranged in the pistons. 10. Engine of Claim 6, characterized in that the crankshaft with a single crank, and all circular blocks of sliding are arranged on one crank pin.
