  • Internal combustion engine control method and control device
    Patent number: 11686268
    Abstract: A control method of an internal combustion engine including an in-cylinder injection fuel injection valve arranged to inject a fuel to a combustion chamber, and a port injection fuel injection valve arranged to inject the fuel to an intake port, the control method includes: sensing or estimating a fuel temperature at a tip end portion of the in-cylinder injection fuel injection valve; sensing an intake pressure; judging whether or not a flash boiling condition based on the fuel temperature and the intake pressure; setting the in-cylinder fuel injection valve to a default fuel injection valve; and injecting an entire or a part of the fuel from the port injection fuel injection valve by decreasing an injection amount ratio of the in-cylinder injection fuel injection valve when the flash boiling condition is satisfied.
