Abstract:
Disclosed are an apparatus and a method for controlling an engine of construction equipment, the apparatus including: a lever for generating a first signal when a state of the construction equipment is switched to an operation state or a neutral state; and an auto idle switch for generating a second signal when an auto engine idle mode is on; in which when a state of the lever is switched to a neutral state in an on state of the second signal, an engine speed is reduced to a step engine speed, when a first speed reducing step is maintained for a predetermined time, the engine speed is further reduced to an idle engine speed, and when a state of the lever is switched to an operation state while the second speed reducing step is maintained, the engine speed returned to the step engine speed.
