Abstract
An engine controlling apparatus includes a setting unit that sets a demand torque to an engine, a detection unit that detects a fluctuation of an external load, and a correction unit that corrects the demand torque. The apparatus includes a target torque calculation unit that calculates a target torque based on the demand torque, a control unit that controls an amount of air to be introduced into the engine so that an output torque may come close to the target torque, and an ignition timing detection unit that detects an ignition timing of the engine. The correction unit adds a torque increment for coping with a fluctuation of the external load to the demand torque to determine an increment correction demand torque and increases or decreases the increment correction demand torque in response to a displacement amount of the ignition timing from a predetermined reference value.
