Abstract
An engine controller includes: a warm-up control unit that performs warm-up operation for letting the engine continuously operate until an integration value of air intake of the engine comes to a predetermined integration value in order to warm up a catalyst provided in an exhaust system when the engine is first started after start-up of the vehicle; and a continuation control unit that lets the engine continuously operate for a predetermined period subsequent to an end of the warm-up operation. The continuation control unit takes an output value of the engine as a request output value when the request output value of the engine is a predetermined idling output value or more that is smaller than the predetermined warm-up output value and takes the output value as the warm-up output value when the request output value is less than the predetermined idling output value.
