| 1. A fuel delivery apparatus for an internal combustion engine having an engine exhaust system, the apparatus comprising components:
a fuel tank; a fuel pump; a fuel line; a first expansion valve; a second expansion valve; an expansion tank; a vapor fuel
injector; a liquid fuel injector; a temperature sensor, a pressure sensor, a controller providing signal processing means;
the fuel line providing fuel communication between:
(a) fuel tank and fuel pump;
(b) fuel pump and first expansion valve;
(c) fuel pump and second expansion valve within an alpha portion of the fuel line positioned in thermal communication with
the engine exhaust system;
(d) fuel pump and liquid fuel injector; and
(e) expansion tank and vapor fuel injector; the expansion valves and temperature and pressure sensors engaging the expansion tank; the injectors engaging the engine;
the controller in signal communication with the sensors, the expansion valves, and the injectors;whereby, the controller meters fuel into the expansion tank through the expansion valves thereby controlling a fuel vapor
in the expansion tank to a temperature set point, and whereby, the controller meters fuel into the engine through the injectors.
