DIESEL ENGINE SUPPLY METHOD Russian patent published in 2003 - IPC

FIELD: mechanical engineering; diesel engines. SUBSTANCE: according to invention gas additional is taken and introduced into fuel in atomizer at end of high-pressure line on mixing section in which mixture is formed between injection cycles, and fuel is saturated with gas addition. Then cyclic portion of mixture is injected into engine combustion chamber. Gas addition is taken directly from combustion chamber space of operating engine at combustion and expansion stroke by suction stroke of delivery valve and soot particles are burnt out from addition. In process of introduction, gas addition is uniformly distributed in fuel on mixing section within the limits of volume of maximum cyclic portion of mixture, and saturation of fuel is carried out by hot working gas containing chemically active radials. Invention is aimed at simplifying organization of supply system owing to taking off gas additional directly from combustion chamber space operating engine, improving degree of fuel preparation before into engine combustion chamber owing to heating of fuel and placing incomplete combustion products into fuel by saturation of fuel with hot working gas containing chemically active radicals and provision of required quality of preparation of cyclic portion of fuel mixture by increasing level of saturation of fuel with gas addition. EFFECT: simplified organization of fuel system. 1 dwg
