1. A supplemental vapor fuel injection system for internal combustion engines, comprising:

  • a source of supply of a supplemental fuel;

    a vaporizer/pressure regulator that is compensated to a load on a given internal combustion engine and operable to receive said supplemental fuel from said source of supply thereof and produce a regulated vapor fuel;

    a fuel injection control assembly connected in flow communication with a post-turbocharger airstream and with said regulator and operable to receive regulated vapor fuel from said regulator and to receive a stream of fuel injection pulses and inject the regulated vapor fuel into the post-turbocharger airstream in accordance with said stream of fuel injection pulses;

    a plurality of sensors operable to sense data in real time relating to operating characteristics of the given internal combustion engine; and

    a controller unit that stores and utilizes a program to generate said stream of fuel injection pulses that controls the injection of the regulated vapor fuel based on an engine manufacturer'"'"'s specifications relating to the given internal combustion engine and real time sensor data received from said plurality of sensors.
