METHOD AND APPARATUS FOR MIXING IN INTERNAL COMBUSTION ENGINE Russian patent published in 1994 - IPC

FIELD: engine engineering. SUBSTANCE: fuel-air mixture is preliminary prepared for supplying to a combustion chamber and separated gas streams are formed outside of zone for supplying fuel-air mixture. Gas streams is injected in flow of fuel-air mixture at points spaced over periphery of cross-section of flow of fuel- air mixture. Gas streams excite acoustical oscillations in each stream at section of forming gas stream A-A. Apparatus has case 1 with passage 2 for supplying fuel- air mixture, supplying passage 3 for supplying gas to passage 2 for supplying fuel-air mixture and many gas passages 5 which connect supplying passage 3 with passage 2 for supplying fuel-air mixture. Inlet section of each gas passage 5 is in communication with supplying passage 3 through throttle passage 6 which provides at least critical pressure drop between supplying passage 3 and inlet section of gas passage 5. EFFECT: enhanced quality of mixing. 6 cl, 8 dwg
