Abstract

The present disclosure provides an engine control device including: an adjustment section that adjusts a flow amount per unit time of exhaust gas from an engine; and a control section that, in a case in which a temperature below freezing point is detected by a temperature detection section that detects an external air temperature or an intake air temperature, a preceding engine operation duration is shorter than a first duration, and a value in a predetermined range in which water in an exhaust pipe can be drained by the flow amount being raised by a certain amount is detected by a value detection section that detects a value representing an acceleration, an accelerator opening or an engine rotation speed, controls the adjustment section so as to raise the flow amount by the certain amount until a second duration has passed from starting of the engine.
