  • Patent number: 7628144
    Abstract: A supercharged internal combustion engine system wherein during periods of high power demand the weight of combustion chamber charge is increased by cooling intake air in a vortex tube operated by high-pressure air from a storage tank. In addition to increasing engine output power, cold air intake also reduces engine pre-ignition (knocking) thereby reducing emissions. Included are means for sensing engine power demand and controlling the supercharging action. Output of the vortex tube may be also used to operate an ejector pump which further compresses intake air and increases charge weight. During periods of natural aspiration the ejector pump can be by-passed to reduce flow impedance. Effective supercharging is achieved even at low engine speeds. One of the objects of the invention is to obtain more power from small displacement ICE and thus providing automotive vehicles with sufficient acceleration in addition to good fuel economy.

  • Patent number: 7568468
    Abstract: A method for operating an internal combustion engine having a fuel pump with a drive shaft is provided, the fuel pump conveying fuel into at least one fuel-collection line, the fuel being subsequently conveyed to at least one combustion chamber via at least one fuel-injection device. In the method, a quantity of the fuel conveyed by the fuel pump into the fuel-collection line is set by means of a valve device. The valve device is configured to selectively connect a discharge side of the fuel pump to a low-pressure region of the fuel pump (during deactivation phase), and selectively disconnect the discharge side from the low-pressure region (during supply phase). In supplying the quantity of fuel, a supply rate, defined as the number of supply phases of the fuel pump per rotation of the drive shaft, is determined as a function of at least one operating parameter of the internal combustion engine.

  • Patent number: 7536981
    Abstract: A hydrogen gas generator in the form of a reformer is used to produce a reformate gas containing hydrogen and at least one other component for use as a fuel or part of a fuel for a compression engine. The hydrogen containing gas blend or mix is used as one component of a fuel for the engine using hydrogen assisted combustion. The hydrogen containing gas produced as the reformate does not require the non hydrogen components to be removed from the gas prior to introduction to the engine either directly or indirectly. This provides a significant saving in cost as pure hydrogen is no longer required for hydrogen assisted combustion.
