Abstract
An engine controller for engine control apparatus is configured to retard an ignition timing, from an engine starting mode timing to a catalyst warm-up mode timing at an idle attainment moment at which an engine idling condition is reached, and to regulate an intake air quantity at a prior moment prior to the idle attainment moment. Moreover, the controller increases a fuel injection quantity by an increase quantity during a period from the prior moment until an intake settlement moment at which an intake air condition settles down. The controller sets the increase quantity of the fuel injection quantity in accordance with a parameter representing a condition of the intake air or fuel supplied to the engine.
