  • Patent number: 8359826
    Abstract: A trouble diagnosis device and method for an NOx sensor for determining abnormality of an NOx sensor used in an exhaust gas purification system. The device can perform a trouble diagnosis without forcedly creating a diagnosis mode during operation of an internal combustion engine and without deterioration of drivability or fuel consumption. The device detects the time-lapse variation of the exhaust NOx flow rate suitable for diagnosis in a normal operation mode and determines whether the NOx sensor responds with following this variation.

  • Patent number: 8336514
    Abstract: A plasma generating device for an internal combustion engine sets the generating-atmosphere pressure for generating plasma to the intake pressure, thereby achieving a reduction in the size, weight, and energy consumption of the plasma generating device and an improvement in combustibility. An internal combustion engine includes a throttle valve arranged in an intake passage having an intake opening that opens to a combustion chamber. An intake valve opens and closes the intake opening. A plasma generating device includes a plasma generator having a generating chamber for converting intake air into a plasma state to generate plasma. The plasma generating device supplies plasma to a downstream passage of the intake passage between the throttle valve and the intake valve. A gas control valve operates in conjunction with the throttle valve, and is arranged in an introduction passage between a clean chamber of the air cleaner chamber and a generating chamber.

  • Patent number: 8215292
    Abstract: Method of operating an internal combustion engine, including, at least, compressing and cooling air outside an engine chamber, supplying cooled, pressurized air to an intake port associated with the chamber, and, during each engine cycle: opening the intake port, allowing cooled, pressurized air to flow through the intake port and into the chamber during at least a portion of the intake stroke; maintaining open the intake port during the portion of the intake stroke and beyond the end of the intake stroke and into the compression stroke and during a majority portion of the compression stroke; closing the intake port at a point during travel of the piston to capture in the chamber a cooled compressed charge of the cooled, pressurized air; controllably delivering fuel into the chamber after the cooled compressed charge is captured within the chamber; and igniting a fuel and air mixture within the chamber.

  • Patent number: 8151553
    Abstract: An internal-combustion engine receives no air from outside atmosphere and it discharges no gas into outside atmosphere. The engine receives fuel, oxygen and recycled combustion gas and its exhaust consists mostly of carbon dioxide and water vapor. Most of the gas exhausted from the engine is recycled back into the engine intake, and the remaining gas is cooled and condensed into liquid carbon dioxide and water. Discharge of greenhouse gas into environment and emission of other harmful air pollutants are eliminated.

    Abstract: A fuel system for an automotive engine is provided that includes a catalytic reactor that is configured to partially oxidize a portion of hydrocarbons in a hydrocarbon based fuel to create a fuel that is more compression ignitable. Exhaust gas is diverted from the exhaust system of an automobile and mixed with a hydrocarbon fuel. The fuel/exhaust gas mixture is exposed to an oxidizing catalyst such that at least a portion of the hydrocarbon fuel is partially oxidized. The resultant fuel mixture is metered into a compression ignition engine for engine operation.
