METHOD OF AND DEVICE FOR OPERATION OF INTERNAL COMBUSTION ENGINE (VERSIONS) Russian patent published in 2005 - IPC

FIELD: mechanical engineering; internal combustion engines.

SUBSTANCE: according to proposed method, part of air is directed to engine through additional parallel circuit, fuel from supply system is fed into additional circuit in which formation of mixture takes place, fuel-air mixture is fed into channels of air circuit near intake valves where it is additionally turbulized and atomized, and control of power and parameters of flow at cylinder input is provided by combined operation of gates of air and additional circuits and control of angles of delivery of flow of additional circuit relative to flow of air circuit. According to other method, part of air flow is directed through additional parallel circuit, fuel from supply system is delivered into engine cylinders where formation of mixture takes place, air from additional circuit is delivered into channels of air circuit near intake valves where swirling is provided, and control of power and parameters of flow at cylinder input is provided by combined operation of gates of air and additional circuits and control of angles of delivery of flow of additional circuit relative to flow of air circuit. Device for implementing said methods is described in invention.

EFFECT: increased economy, decreased toxicity of engine exhaust gases.
