METHOD OF AND DEVICE FOR DELIVERY OF FUEL INTO CYLINDERS OF INTERNAL COMBUSTION ENGINE Russian patent published in 2003 - IPC

FIELD: mechanical engineering; internal combustion engines. SUBSTANCE: according to proposed method, fuel is delivered into engine intake manifold, is mixed with air, heated and fed to engine cylinders in drop-like and vapor state. Fuel is delivered to section of manifold on which conditions for uphill boiling of fuel can form. Fuel film is divided into movable drops out of contact with manifold surface and then drops are delivered on vapor pads along surface of intake manifold, on which above-indicated conditions are maintained, to engine cylinders. Device for delivering fuel into cylinders of internal combustion engine has fuel feeding device and intake pipeline in which sections arranged successively are made in form of separate members brought inside pipeline on which conditions of appearance and maintenance of uphill boiling of fuel are provided. EFFECT: increased economy and power output of engines. 3 cl, 1 dwg
