CONTROLLER FOR INTERNAL COMBUSTION ENGINE

摘要

A final fuel injection amount TAU to be supplied to an engine 1 is calculated using as parameters a manifold pressure compensation value found by adding a difference between the atmospheric pressure PAbase at a base location detected by an atmospheric pressure sensor 23, that is, an atmospheric pressure difference, and a manifold pressure PM detected by a manifold pressure sensor 21 and an engine speed NE detected by a crank angle sensor 22. By taking into consideration the change in atmospheric pressure with respect to a manifold pressure compensation value and reflecting it into the manifold pressure parameter, a suitable fuel injection amount can be supplied regardless of any change in atmospheric pressure, the operating state of the engine 1 is maintained well, and the drivability can be secured. <IMAGE>
