To control fuel injection timings to two intake ports of a cylinder to promote mixing and gasification of the fuel, the internal combustion engine includes a first intake port (7a) and a second intake port (7b) which are connected to a cylinder (9), a firs...

Because a fuel temperature is low in a cold state, adhesion of fuel to a piston is increased and PMs are increased. By injecting fuel during a time period after an exhaust valve is closed but before an intake valve is opened, vaporization is promoted, and ...

Provided is a control device for an internal-combustion engine provided with a throttle valve installed in an intake path. A full intake air amount, which is the intake air amount corresponding to when the throttle valve is fully open, is calculated in acc...
