Abstract
A cowling for housing an outboard engine. The cowling includes a plurality of walls defining at least in part an engine compartment. An engine compartment inlet, in fluid communication with the engine compartment, is defined at least in part by at least one of the plurality of walls. A hydrophobic mesh member disposed across the inlet is adapted to prevent at least a portion of a water content of an airflow flowing to the engine compartment via the engine compartment inlet from entering the engine compartment. An outboard engine having the cowling is also disclosed.
Claims21
A cowling for housing an outboard engine, the cowling comprising:
- a plurality of walls defining at least in part an engine compartment;
- a first engine compartment inlet in fluid communication with the engine compartment and being defined at least in part by at least one of the plurality of walls;
- a hydrophobic mesh member disposed across the first engine compartment inlet, the mesh member being adapted to prevent at least a portion of a water content of a first airflow to the engine compartment flowing via the first engine compartment inlet from entering the engine compartment;
- a second engine compartment inlet in fluid communication with the engine compartment and being defined at least in part by at least one of the plurality of walls;
- and
- a passage fluidly communicating with the second engine compartment inlet and thereby with the engine compartment, the passage being defined at least in part by at least one of the plurality of walls, the passage being adapted to conduct a second airflow toward the second engine compartment inlet from the passage, the second airflow flowing through the second engine compartment inlet to the engine compartment, the passage being adapted to conduct the second airflow into the engine compartment via a circuitous path having at least one bend to cause a reduction in a water content of the second airflow.
An outboard engine comprising:
- an engine, the engine comprising:
- at least one cylinder;
- a combustion chamber defined by the at least one cylinder;
- and
- a throttle body having a throttle body inlet fluidly connected to the combustion chamber;
- and
- a cowling having a plurality of walls defining at least partly an engine compartment housing at least a portion of the engine, the cowling comprising:
- a first engine compartment inlet defined at least in part by at least one of the plurality of walls;
- a first passage fluidly communicating the first engine compartment inlet with the combustion chamber and being defined at least in part by at least one of plurality of walls;
- a hydrophobic mesh member being disposed in one of the first engine compartment inlet and the first passage, the mesh member being adapted to prevent at least a portion of a water content of a first airflow to the engine compartment via the first engine compartment inlet from entering the engine compartment;
- a second engine compartment inlet defined at least in part by at least one of plurality of walls;
- and
- a second passage fluidly communicating with the second engine compartment inlet and being defined at least in part by at least one of plurality of walls, the second passage being adapted to conduct a second airflow toward the second engine compartment inlet from the second passage, the second passage being adapted to cause the second airflow to flow from the second engine compartment inlet via a circuitous path to the combustion chamber and to thereby cause a reduction of a water content of the second airflow.
