Latest Patents
Nunome’s listed patents address fuel delivery and vapor control in outboard engines.
“Fuel Supply System for Outboard Motor” describes a system that vents fuel vapor from a vapor separator through a vapor relief valve. The valve regulates vapor delivery to the air induction system according to incoming airflow and/or engine speed, and prevents vapor from venting into the system when the engine is off.
“Fuel Supply Apparatus and Vapor Separator in Outboard Engine” describes a low-pressure pump supplying fuel to a vapor separator with an air discharge port. A ball valve closes the port as the fuel level rises. When the separator fills, the valve seals it, allowing the fuel inside to become pressurized.
