    Abstract: An internal combustion engine is powered on or using a mix of a liquid fuel and hydrogen, to produce energy that is converted into electricity using an alternator, which is subsequently used to produce hydrogen. The hydrogen is produced through the use of hydrogen generating cells which breaks down water using electrolysis and outputs hydrogen. The cell uses anode rods inserted into a tank containing cathode tubes. Additionally, the tank itself also acts as the cathode as the tank is connected to the negative end of a circuit. A current passes from the anode rods to the cathode through water to produce hydrogen. Hydrogen is off gassed and stored in a reservoir to be used in an internal combustion engine as fuel. The energy needed to perform electrolysis is garnered from an alternator and a turbine that is part of the system.

  • Patent number: 9206769
    Abstract: A method and system for using an internal combustion engine with dedicated EGR cylinders to provide an adjustable EGR rate to the main (non dedicated) cylinders. The dedicated EGR cylinder(s) are configured to receive fresh air via a fresh air intake or to receive a portion of the mixture of fresh air and EGR gas via the same mixed intake line that delivers intake to the main cylinders. If the dedicated EGR cylinder(s) receive only fresh air, the main cylinder(s) receive EGR at higher EGR rate. If the dedicated EGR cylinder(s) receive only the portion of fresh air and EGR gas, the main cylinder(s) receive EGR at a lower EGR rate. The EGR rate to the main cylinder(s) may be adjusted between these rates in response to operating conditions of the engine.

  • Patent number: 9140181
    Abstract: A primary reciprocating engine is combined with a secondary turbine engine. The turbine engine utilizes the exhaust of the reciprocating engine as fuel, resulting in an increase in efficiency and reduction in emissions over a conventional reciprocating engine alone. The secondary turbine engine powers secondary functions of the reciprocating engine, such as relieving the back pressure at the exhaust ports, driving the turbocharger that pressurizes the air intake, and driving an electrical generator. Oxyhydrogen (HHO) used to ignite the reciprocating engine exhaust and complete combustion of the reciprocating engine fuel is obtained by disassociating distilled water into hydrogen and oxygen using the electricity from the electrical generator.
