Title:
ACCUMULATOR FUEL INJECTION DEVICE
Document Type and Number:
Japanese Patent JP3952111
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To perform a fuel injection compatible to an engine operating state also when pressure of fuel supplied from an accumulator to a switching valve and an injector is not maintained to target pressure, to improve an exhaust gas characteristic and to reduce operating noise.
SOLUTION: A controller 8 increases, decreases or corrects driving signal differential time from an impressing point of time for an injector driving signal till an impressing point of time for a switching valve driving signal according to a difference of target pressure and actual pressure of fuel within accumulators 3, 4, compensates increased/decreased parts for operation delay time of an injector 9 and a switching valve 5 due to follow-up delay of actual pressure for an increased/decreased change of target pressure and opens the injector 9 and the switching valve 5 at a proper time.
