INTERNAL COMBUSTION ENGINE CONTROL DEVICE

摘要

This invention relates to a control device (1) of an internal combustion engine (10) having an in-cylinder injection valve (11) which injects fuel into an air cylinder (20), and a port injection valve (12) which injects fuel into an intake port (17). An injection amount calculation means (5) is provided which calculates the in-cylinder injection amount injected from the in-cylinder injection valve (11). Further provided are a port injection control means (2) which controls the port injection amount injected from the port injection valve (12), and an overlap period control means (4) which controls overlap periods in which both an intake valve (27) and a discharge valve (28) are in an open state. Furthermore, a change means (6) is provided which, on the basis of the in-cylinder injection amount, changes both the overlap period and the port injection amount from the port injection valve (12).
