ROTOR-PISTON INTERNAL COMBUSTION ENGINE Russian patent published in 2009 - IPC F02B55/14 F01C21/04 

FIELD: engines and pumps.

SUBSTANCE: invention relates to engine production. The proposed rotor-piston ICE incorporates a housing with two intersecting annular cylinders, each accommodating four arc-like cylinders that house four arc-like pistons, and output shaft linked up with arc-like pistons. The output shaft is arranged inside the housing and features the central spherical part with inclined grooves made at an angle to each other and to the output shaft lengthwise axis, and intercommunicated in pairs. The engine annular intersecting cylinders feature a cross-section representing a truncated oval. Sectors of the links are arranged in symmetry relative to the link cylindrical pins. Four combustion chambers are arranged in pairs in the output shaft cylindrical parts wherein inclined groove chambers get together. One part of arc-like collars making four oil pumping pairs are made on one of the side surfaces of inclined grooves, while the arc-like grooves making the oil pumping pairs are arranged on one the side surfaces of links' sectors. The oil tank is located above the output shaft lengthwise axis to allow a gravity feed of oil into the chambers of pumping pairs.

EFFECT: increased specific power, efficiency and reduced fuel consumption.
