Title:
FUEL INJECTION CONTROL SYSTEM
Document Type and Number:
Japanese Patent JP2018204528
Kind Code:
A
Abstract:
To make a control device control an output period of an injection signal according to fuel pressure before and after a start of an output of the injection signal while transmitting the fuel pressure of an injector which is detected by a fuel pressure sensor to the control device after being converted to digital data.SOLUTION: An ECU 30 sets a detection period of fuel pressure corresponding to the start timing of fuel injection, and transmits the detection period to a signal processing circuit 25 in advance. When the arrival of the received detection timing is determined, the signal processing circuit 25 transmits the digitalized pressure data indicating the fuel pressure which is detected by the fuel sensor 22 to the ECU 30 at that timing.SELECTED DRAWING: Figure 1
