Abstract
A water ingestion control system for an internal combustion engine can include a snorkel, at least one closure structure, a choking valve, and a controller. The snorkel can include an air intake opening and at least one evacuation inlet that can be selectively opened and closed by the closure structure. The choking valve can be located between the air intake opening and an air box and selectively open and close fluid communication between the snorkel and the air box. When in a closed state, the choking valve can close fluid communication between the snorkel and the air box and prevents fluid in the snorkel from flowing into the air box and the engine. The controller can be configured to place the choking valve in the closed state when the controller receives data indicative of the presence of water in the snorkel.
