A fuel vaporizer system for an internal combustion engine including a first closed chamber defining a first volume, the first closed chamber having a heat transfer surface; a second closed chamber at least partially surrounding the first closed chamber and defining a second volume; and a third closed chamber at least partially surrounding the second closed chamber and defining a third volume. A liquid fuel supply system including a liquid fuel supply line emits fuel into the first volume in an expanding pattern of liquid fuel spray from at least one orifice. A thermal fluid system from said engine is configured to circulate fluid, which may be engine coolant, through the second volume and transfer heat from the fluid through the first closed chamber and vaporize said liquid fuel. An exhaust system from said engine is configured to circulate exhaust through the third volume and transfer heat from the exhaust through the second closed chamber and heat said fluid. A vaporized fuel outlet is configured to direct vaporized fuel from the first closed chamber to supply fuel to at least one combustion region of the internal combustion engine via a combustion fuel supply line.
