FUEL-INJECTION SYSTEM OF MULTIFUEL DIESEL ENGINE WITH DRAINLESS FUEL FEED

摘要

FIELD: mechanical engineering; internal combustion engines. ^ SUBSTANCE: invention relates to fuel injection system of diesel engines. Proposed fuel injection system of multifuel diesel engine with drainless fuel feed has nozzle with space over needle communicating with underneedle space through channel in which bypass valve is installed, and high-pressure pipe with plunger pump. System includes additionally fuel pressure drop spool in high-pressure pipeline and valve to make up high-pressure pipeline with fuel. System contains also device to control fuel pressure drop spool and make-up valve, high-pressure accumulator, springless bypass ball valve to let fuel out of space accommodating spring of nozzle needle. ^ EFFECT: increased power, economy and reliability of engine in operation, reduced toxicity of exhaust gases. ^ 2 dwg
