At least one of nozzle holes is provided as a non-circular nozzle hole where the ratio of the longest diameter to the shortest diameter of an outlet opening portion is greater than 1. A virtual non-circular cone and a virtual circular cone are defined for each of the non-circular nozzle hole and a circular nozzle hole where the ratio of the longest diameter to the shortest diameter of the outlet opening portion is 1. At least two adjacent nozzle holes are formed such that the virtual non-circular cone does not interfere with the virtual circular cone or the virtual non-circular cone.

Fuel injection valve

An engine control apparatus for controlling output torque of an engine includes a target determining unit for determining a target value of an injection quantity of fuel on the basis of pressure in a cylinder of the engine. The engine control apparatus further includes an injection control unit for controlling the injection quantity at the target value in a startup injection control period in starting of the engine. The startup injection control period is between a specific startup timing and an end timing where a specific condition is satisfied.
