  • Patent number: 11300045
    Abstract: Methods and systems are provided for operating an electric motor to drive either a transmission fluid pump or a direct injection fuel pump. In one example, a method may include operating an electric motor to drive a direct injection fuel pump to supply fuel to a direct injection fuel rail while an engine of a start/stop vehicle is on, and operating the electric motor to drive an auxiliary transmission fluid pump to circulate transmission fluid to a transmission rotationally coupled to the engine while the engine is off during an auto-stop. In this way, the direct injection fuel pump may be electrically driven without increasing vehicle costs through adding an additional electric motor.

  • Patent number: 11280255
    Abstract: A system, apparatus and associated method for the catalyzation of a fossil fuel prior to combustion within an internal combustion engine. A voltage is inputted from a source to a relay and an ignition circuit in separate communication with the relay. The relay converts the input voltage to a negative output voltage applied to a fuel line in communication with a fuel injector of the engine, resulting in a negative charge imparted to the fuel prior to combustion and in order to increase oxidation/burn efficiency with resultant mileage/horsepower increase and concurrent decrease in pollutants resulting from discharge of partially combusted reactants.
