METHOD OF CONTROL OF OPERATION OF ELECTROMAGNETIC VALVE DESIGNED FOR METERED OUT DELIVERY OF GASEOUS FUEL INTO CYLINDERS OF INTERNAL COMBUSTION ENGINE

摘要

FIELD: mechanical engineering; engine fuel systems. SUBSTANCE: invention relates to electronic fuel systems of internal combustion engines, especially to electronic control of parameters of command signal. Proposed electromagnetic valve designed for metered out delivery of gaseous fuel into internal combustion engine is operated by microcontroller consisting of forcing, holding and demagnetizing stages. Levels of forcing, holding and demagnetizing currents are adjusted to suit supercharging air pressure in air receiver of internal combustion engine. EFFECT: improved stability and reliability of electromagnetic gas valve with provision of control of its response at minimized dissipation of power in electromagnetic coil. 3 dwg
