FIELD: internal combustion engines.
SUBSTANCE: invention can be used in internal combustion engines. A method for improving the efficiency of a reciprocating internal combustion engine consists in converting the rotational movement of the profiled cams (5), (12) of the cam shafts (4), (11) into the reciprocating movement of the spring-loaded rod (3) of the piston (2), resulting in In the cylinder (1) of the engine, the processes of filling, compression, combustion, the working cycle and the release of gases of combustion products are performed. At the beginning of the working cycle, the rollers (6), (13) of the rod (3) of the piston (2) slide off the top of the profiled cam (5), (12) and the rod (3) with spring-loaded rocker arms (7), (14) moves down. The rocker arms (7), (14) during movement contact with the top of the profiled cams (5), (12) and as the rod (3) moves down, they compress the springs (10), (16) of the rocker arms (7), (14). Throughout the entire path of movement of the rod (3), the rocker arms (7), (14) act on the tops of the cams (5), (12) due to the springs (10), (12), ensuring the rotation of the cam shafts (4), (11) connected to the shaft (20) of the load. At the beginning of the working stroke, the rollers (6), (13) mounted on the ends of the T-shaped rod (3) of the piston (2) roll off the tops of the profiled cams (5), (12) and, together with the spring-loaded rocker arms (7), (14) move down. During the entire movement of the T-shaped rod (3), the rocker arms (7), (14) due to the springs (10), (16) act on the tops of the cams (5), (12), providing rotation in opposite directions of the cam shafts (4), (11) connected to the load shaft (20) by gears (17), (18), (19). In the case of combining single-cylinder engines into a multi-cylinder engine, the automatic control system ensures the operation of the electric drives (25) of the springs (10), (16) of the T-shaped piston rods (3) in such a way that the single-cylinder engines that are part of the multi-cylinder engine operate either alternately, either in groups or at the same time.
EFFECT: preventing lateral pressure of the piston on the rod and reducing heat loss.
