Title:

CONTROL DEVICE AND CONTROL METHOD FOR INTERNAL COMBUSTION ENGINE

Document Type and Number:

WIPO Patent Application WO/2016/162911

Kind Code:

A1

Abstract:

In the present invention an internal combustion engine (1) has a direct injection fuel injection valve (8) and a port injection fuel injection valve (9). The requested fuel injection amount is calculated in response to an engine operation condition, and when this requested fuel injection amount is in a first operation region (R1) in which the minimum fuel injection amount of the direct injection fuel injection valve (8) is exceeded, the fuel injection amount of the direct injection fuel injection valve (8) is adjusted on the basis of the requested fuel injection amount and a fixed amount, while maintaining the fuel injection amount of the port injection fuel injection valve (9) at that fixed amount. The first operation region is at least a region in which the requested fuel injection amount exceeds the minimum fuel injection amount of the direct injection fuel injection valve. In this first operation region the fuel injection amount of the port injection fuel injection valve is fixed at the minimum fuel injection amount of this port injection fuel injection valve.
