Title:
CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2019/017060
Kind Code:
A1
Abstract:
Provided is a control device which is for an internal combustion engine that uses a fuel containing alcohol, and which is capable of ensuring a stable and good combustion state after the internal combustion engine is cold-started. The present invention is applied to an internal combustion engine 3 that uses a fuel containing alcohol and that directly injects the fuel into a cylinder 3a. A control device according to the present invention detects an engine water temperature TW as an engine temperature parameter indicating the temperature of the internal combustion engine 3, detects the ethanol concentration EC of the fuel, and detects an intake air amount GAIRCYL as a load of the internal combustion engine 3. Then, after a cold-start of the internal combustion engine 3, the control device selects, as a fuel injection mode, either intake process injection for injecting the fuel during an intake process or compression process injection for injecting the fuel during a compression process, on the basis of the detected engine water temperature TW, the detected ethanol concentration EC, and the detected intake air amount GAIRCYL, and executes the selected injection (step 9 in FIG. 2, FIG. 6, FIG. 12).
