Title:
ACCUMULATOR FUEL INJECTION DEVICE OF DIESEL ENGINE
Document Type and Number:
Japanese Patent JP3116769
Kind Code:
B2
Abstract:
PURPOSE: To provide an accumulator fuel injection device for backing up so as to be operated from an engine stall by a trouble without adding a sensor at the trouble time of a pressure sensor by that a signal is held to a voltage value showing a high pressure.
CONSTITUTION: The device in the title is provided with a judging function for judging whether the output of a pressure sensor 28 is returned to a pressure value 0 or not and a mode change function for calculating the pressure of a pressure accumulating tank 25 by the press-feed amount of a high pressure feed pump 1 and the fuel injection amount of a fuel injection nozzle 10 when it is not 0 and changing over this pressure to a control replaced to the pressure value of the output of a pressure sensor until now, at the engine stall time having occured during an engine running. Thereby, at the engine stall time by such trouble that a high pressure value is outputted continuously so that the pressure sensor can reduce the press-feed amount of the high pressure feed pump, after the engine stall time, in stead of the control carried out by the pressure value outputted from the pressure sensor, an operation can be restarted by changing over to the control of a calculated pressure value.
