METHOD OF SUPPLY OF INTERNAL COMBUSTION ENGINE Russian patent published in 1994 - IPC

FIELD: mechanical engineering; engines. SUBSTANCE: hydrogen under depression is delivered into intake channel through non-return gas dynamic valve. Delivery of hydrogen starts later than commencement of suction, i. e. when rarefaction in intake channel becomes greater than rarefaction of hydrogen. Hydrogen delivery cutoff and closing of gas dynamic valve take place at the moment when rarefaction in intake channel decreases to value of hydrogen rarefaction at deceleration of air flow in intake channel at end of intake. After hydrogen delivery cutoff the last phase of filling continues. Gas dynamic valve prevents air feed into hydrogen channel. EFFECT: enhanced reliability of operation of internal combustion engine owing to prevention of backfires at intake stroke. 1 dwg
