Accumulator-type fuel injection system

摘要: During a transitional operation of an engine in which load is changed suddenly from high to low load, control for extending opening period change-over valve adapted switch low-pressure accumulator and high-pressure one the other during fuel injection carried out increase flow rate supplied thereby reduce pressure accumulator, whereby response delay minimized. accelerated operation, kept open until connected portion passage on downstream side reaches indicated level, predetermined time elapses after finishing time, formation promoted obtain condition suiting operating engine.
