Abstract: An engine apparatus is provided that includes an internal combustion engine and a cooling airflow control subsystem The cooling airflow control subsystem includes an airflow regulator having a first component comprising one or more passageways extending through the first component, and a second component comprising one or more passageways extending through the second component, the second component mounted adjacent the first component; and an actuator operably coupled to the airflow regulator to cause relative rotation between the first and second components when actuated so that the airflow regulator can be altered between: (1) a first state in which the first and second passageways are aligned a first extent to allow a first amount of cooling airflow to reach the engine; and (2) a second state in which the first and second passageways are aligned a second extent to allow a second amount of cooling airflow to reach the engine, the first amount being greater than the second amount.

Abstract: Systems and methods for electronically controlling the fuel-to-air ratio of a fuel mixture supplied to an internal combustion engines are disclosed. In one aspect, electronic control systems and methods are provided that determine and automatically move a choke valve in accordance with a first ramp having a first characteristic that is dependent on engine temperature and ambient air temperature. In another aspect, an integrated ignition and electronic auto-choke module is provided. In yet another aspect, electronic control systems and methods are provided that dynamically control a movement characteristic of a choke valve using a feedback loop.
