Fuel vaporizer system

A fuel vaporizer, comprising:

• a housing;
• first and second baffles joined to the housing and extending across a width of the housing;
• and
• a conduit extending through the first and second baffles, the conduit being in thermal communication with exhaust, and the conduit being in thermal communication with fuel in a mist form,
• wherein the conduit is further in thermal communication with the first and second baffles,
• wherein the first and second baffles are in thermal communication with the housing, and
• wherein the first and second baffles and the housing are configured to together contain and be in thermal communication with a pool of fuel along a bottom wall of the housing.

A method of operating an internal combustion engine, given a fuel, an airflow, and exhaust gas from the internal combustion engine, the method comprising:

• flowing the exhaust gas through a conduit comprising a turbulator joined inside the conduit, the conduit passing through first and second baffles within and extending across a width of a housing, the exhaust gas transferring thermal energy to the conduit;
• flowing the fuel into the housing;
• flowing the airflow through the housing, the airflow flowing around the conduit;
• transferring thermal energy from the conduit to the airflow in the housing, the thermal energy vaporizing a first portion of the fuel into the airflow and generating a flow of vaporized fuel;
• providing the flow of vaporized fuel to an intake of the internal combustion engine;
• and
• collecting a second portion of the fuel as a pool of fuel within a chamber defined by the first and second baffles and the housing along a bottom wall of the housing.
