    摘要： Internal combustion engine (1) has direct injection fuel injection valve (8) and port injection fuel injection valve (9). A requested fuel injection amount is calculated according to an engine operation condition. When the requested fuel injection amount is in first operation region (R1) in which the minimum fuel injection amount of direct injection fuel injection valve (8) is exceeded, a direct injection fuel injection valve (8) fuel injection amount is adjusted based on the requested fuel injection amount and a fixed amount, while maintaining a port injection fuel injection valve (9) fuel injection amount at the fixed amount. First operation region is at least a region in which the requested fuel injection amount exceeds the direct injection fuel injection valve minimum fuel injection amount. In first operation region, the port injection fuel injection valve fuel injection amount is fixed at the minimum fuel injection amount of port injection fuel injection valve.
