1. A system for modifying diesel powered electric generators so as to be operated either in a full diesel fuel mode or a gas-diesel fuel mode, at substantially equivalent operating efficiencies, said system comprising:

  • a) a gas control sub-system designed to control the amount of gas supplied to a driving engine of the generator while being operated in the gas-diesel fuel mode, b) a diesel control sub-system designed to control the amount of diesel fuel supplied to the driving engine while being operated in the gas-diesel fuel mode, c) an electronic control sub-system designed to regulate operation of pre-determined components of the gas control sub-system and the diesel control sub-system, and d) the gas control sub-system, the diesel control sub-system and the electronic control sub-system being collectively interdependent so as to allow a change of operation of the generator between the full diesel fuel mode and the gas-diesel fuel mode without generator power output being interrupted; and

    e) the gas control sub-system structured to permit the amount of gas supplied to the driving engine to be determined in response to the load requirements of the driving engine, and at least said gas control sub-system operating independently from a governor of the diesel engine; and

    f) said electronic control sub-system further structured to determine load levels through the monitoring of the driving engine'"'"'s manifold air pressure.
