METHOD OF FUEL MIXTURE SUPPLY INTO INTERNAL COMBUSTION ENGINE AND CARBURETOR AIR-FUEL RATIO ADJUSTING SCREW Russian patent published in 1999 - IPC

FIELD: mechanical engineering; fuel systems of internal combustion engines. SUBSTANCE: fuel-air mixture flow and main air flow are delivered into CARBURETOR mixing chamber. Main air flow is supplied through choke valve. Simultaneously additional turbulent air flow is formed in which frequency of oscillations of air particles within ultrasonic oscillation range is provided. Additional turbulent air flow is delivered at angle to fuel-air mixture flow to homogenize the latter by breaking particles of fuel and harmful admixtures. EFFECT: increased engine efficiency, reduced carbon monoxide (CO) content in exhaust gases to level 5-30 times lower as compared with existing design versions. 4 cl, 1 dwg
