| description | A control apparatus for speedily warming up a catalyst disposed within an exhaust pipe connected to an internal combustion engine. The control apparatus first determines a fuel injection amount and an ignition timing of the engine on the basis of an engine operating condition such as an intake air pressure of the engine and a rotational speed of the engine. The control apparatus is also responsive to temperature information of the catalyst for adjusting the fuel injection amount and the ignition timing in accordance with the catalyst temperature information. When the catalyst temperature does not reach the effectively emission-purifying temperature, the control apparatus alternately adjusts the fuel injection amount to a rich side and a lean side and further intermittently retards the ignition timing. This injection and ignition control operation allows acceleration of the warming-up of the catalyst to suppress the deterioration of the emissions from the engine. |
