Fuel vapor separator and heat exchanger for a marine outboard engine

A heat exchanger for a fuel vapor separator, the heat exchanger comprising:

• a heat exchanger body;
• a first fuel channel defined by the heat exchanger body, the first fuel channel including an inlet adapted for receiving fuel from an engine connected to the fuel vapor separator;
• a second fuel channel defined by the heat exchanger body, the second fuel channel including an outlet adapted for fluidly communicating with a fuel reservoir of the fuel vapor separator,
• an outlet of the first fuel channel being fluidly connected to an inlet of the second fuel channel;
• and
• at least one coolant channel defined by the heat exchanger body,
• the first fuel channel, the second fuel channel, and the at least one coolant channel being in thermal communication,
• the first fuel channel, the second fuel channel and the at least one coolant channel being parallel.

A marine outboard engine, comprising:

• an internal combustion engine including at least one fuel injector;
• a fuel vapor separator including:
• a separator body,
• a fuel reservoir defined at least partially by the separator body, and
• a first fuel pump fluidly connected between the fuel reservoir and the at least one fuel injector;
• a fuel tank for supplying fuel to the internal combustion engine;
• and
• a second fuel pump fluidly connected between the fuel tank and the fuel vapor separator,
• the fuel vapor separator further comprising:
• a heat exchanger disposed at least partially in the separator body, the heat exchanger comprising:
• a heat exchanger body;
• at least one fuel channel defined by the heat exchanger body, the at least one fuel channel including:
• an inlet adapted for receiving fuel from the engine, and
• an outlet fluidly communicating with the fuel reservoir;
• and
• at least one coolant channel defined by the heat exchanger body,
• the at least one fuel channel and the at least one coolant channel being in thermal communication.
