RESONANCE SUPERCHARGING SYSTEM FOR INTERNAL COMBUSTION ENGINE (VERSIONS) Russian patent published in 1998 - IPC

FIELD: mechanical engineering; intake devices of internal combustion engines making use of oscillations of column of air or combustible mixture in pipe lines. SUBSTANCE: internal combustion engine resonance supercharging system includes intake manifold and resonator unit connected to it; resonator unit has varying parameters and is made in form of cavity resonator with inner partition fitted for motion along axis in case of pressure drop between resonator bottom and fixed position. Partition is provided with devices for bypass of gaseous medium. According to another version, shut-off member is provided which is mounted at cavity resonator inlet; provision is also made for device for bypass of gaseous medium in form of calibrated orifice in the partition (needle-hole). EFFECT: possibility of nonharmonic periodic oscillations; enhanced efficiency of supercharging. 5 cl, 5 dwg
