A method of controlling an engine based on an oxygen storage capacity of a catalytic converter

摘要

A method of controlling an engine (102) comprising determining a capacity of a catalytic converter (162) for storing oxygen; andcontrolling a speed of an engine (102) based on the oxygen storage capacity of the catalytic converter (162) and / or an ignition timing of the engine (102) based on the oxygen storage capacity of the catalytic converter (162), wherein the engine speed is set at a first speed; when a temperature of the engine (102) is less than a first temperature while the engine (102) is starting; and wherein when the engine temperature is less than or equal to the first temperature while the engine (102) is starting and the oxygen storage capacity of the catalytic converter (162) is less than a predetermined value, the engine speed is selectively set to a second speed greater than the first speed is.
