| description | It is an object of the present invention to improve estimation accuracy of an air excess ratio within a fuel spray and quickly cause the air excess ratio to approximate to a target value when the engine load factor rises. An internal combustion engine control apparatus (30) includes an information acquiring section (41) that acquires an air intake parameter and a fuel parameter, a first estimation section (42) that estimates an in-fuel-spray air excess ratio using the air intake parameter and fuel parameter, and a pressure calculation section (44) that calculates, when the in-fuel-spray air excess ratio is less than a target in-fuel-spray air excess ratio, a necessary fuel injection pressure to match the in-fuel-spray air excess ratio with the target in-fuel-spray air excess ratio, in which when the necessary fuel injection pressure is equal to or less than a maximum injection pressure, fuel injection is performed at the necessary fuel injection pressure. |
