Abstract
An adaptive-adjustment method for engine operation includes: upon receipt of an instruction, reducing a ratio of air to fuel of an engine until a rotational speed after the reduction is less than the rotation speed before the reduction, and a rotational speed difference between the rotational speeds before and after the reduction is greater than a preset drop value; increasing the ratio of air to fuel of the engine until the rotational speed after the increase is less than the rotational speed before the increase, and a rotational speed difference between the rotational speeds before and after the increase is greater than the preset drop value; determining an offset of a control parameter corresponding to an adaptive-adjustment state for the engine according to a reduced ratio of air to fuel and an increased ratio of air to fuel; and controlling the engine at a current time according to the offset.
