FIELD: motors and pumps.
SUBSTANCE: reciprocating internal combustion engine comprises a cylinder with a piston and a rotor in the housing. The rotor is kinematically connected with a crankshaft and periodically connects the cylinder cavity with inlet and outlet ports of the combustion chamber. The rotor is made with blades, forming with the rotor surface between them the combustion chamber. The rotor is kinematically connected to the rollers. The rollers have recesses to pass the blades and divide the space between the housing and the rotor to the annular chambers. One of the annular chambers communicates with the cylinder cavity. In the rotor, the shaft is mounted coaxially and with the ability of rotation. The shaft diameter is equal to the diameter of the rotor. On the shaft in the radial direction at least one recess is formed. The width of the recess on the shaft surface is smaller than the distance on the rotor surface between the blades. The end of the shaft protrudes beyond the rotor end. The protruding end is made in the form of as a worm gear wheel.
EFFECT: reduction of harmful emissions into the atmosphere and improvement of the operational characteristics.
