Title:
FUEL SUPPLY DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/018131
Kind Code:
A1
Abstract:
Provided is a fuel supply device with which fuel consumption can be improved by optimizing the switching instruction timing and the fuel injection timing, and by preventing the actual fuel injection amount from diverging from the desired fuel injection amount even when the fuel pressure is switched. An ECU determines whether a fuel pressure switching request has been generated (step S11). When the fuel pressure is low and the engine is warming up or the fuel temperature is high, the ECU determines that a fuel pressure switching request has been generated (YES in step S11), and calculates a valve-switching delay time t1 (step S12). Then, the ECU references the injection timing which is based on the fuel injection control and sets the timing for switching such that the switching of the fuel pressure does not overlap the fuel injection timing (step S13).
