Internal combustion engine system and method

An internal combustion engine system for fueling an internal combustion engine with diesel fuel and with hydrogen gas, the system comprising:

• an internal combustion engine adapted to operate on diesel fuel or on hydrogen gas, and on a combustion thereof;
• a hot water radiator adapted to cool said internal combustion engine and to dispense water therefrom;
• a gas exhaust for dispensing exhaust gas from said internal combustion engine;
• a steam boiler adapted to receive water and exhaust gases from said radiator and said exhaust gases from said internal combustion engine, and producing steam;
• a steam engine adapted to receive steam from said boiler and having means for generating electricity;
• an electric generator adapted to be driven by said steam engine;
• a hydrogen generator powered by said electric generator and adapted to produce hydrogen gas;
• and
• fuel input means adapted (1) to deliver hydrogen gas from said hydrogen generator, and (2) to deliver diesel fuel to said internal combustion engine;
• wherein said internal combustion engine is adapted to be initially fueled by the diesel fuel and thereafter to be fueled by a combination of hydrogen gas and diesel fuel.
