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: An internal combustion engine that includes an oil baffle in the oil sump. The internal combustion engine may include a crankcase comprising an oil sump containing an oil reservoir, a crankshaft, and an oil baffle positioned within the oil sump. The crankshaft may be a vertical crankshaft and a first balance shaft may extend upward from the oil baffle. The crankshaft may be positioned within the oil baffle and a drivetrain may, also optionally, be positioned in the oil baffle. The internal combustion engine may be configured such that the oil reservoir has a first oil level when the internal combustion engine is off and a second oil level when the internal combustion engine is running at normal operating conditions. The first oil level is above a floor of the oil baffle. The second oil level may, also, be above the floor of the oil baffle.
