Abstract
In order to provide for reduced internal combustion engine exhaust emissions when cold starting an internal combustion engine, there is provided two methods and systems for cold starting an internal combustion engine, and one method and system for shutting down an internal combustion engine. The methods and systems are directed towards: (1) a preheating of a minimum of one thermally activated sensor within an internal combustion engine prior to cold starting of the internal combustion engine; (2) an autocranking of an internal combustion engine while metering fuel into the internal combustion engine and timing ignition within the internal combustion engine such as to reduce internal combustion exhaust emissions when cold starting the internal combustion engine; and (3) a phased shut down of fuel supply control followed by ignition source control when shutting down an internal combustion engine after operating the internal combustion engine.
