Patent number: 7320298Abstract: Internal combustion engines generally suffer from inadequate time to completely combust all the fuel in a given cycle. Therefore, any method for increasing the rate and completion of combustion is welcomed. A large excess of electrons are admitted to the combustion zone attached to a fine water droplet spray. The charged spray enters through the air intake valves at the beginning of the intake stroke. The charged spray becomes well mixed with the charge of air prior to fuel injection and the well mixed electrons provide for catalytic action. Electron catalyzed combustion reactions occur faster and at lower temperatures. The lower temperature reduces NOx and the faster burning increases efficiency and reduces soot formation. The catalytic benefits of charged water fumigation is only observed once the electron concentration exceeds a threshold value.Type: GrantFiled: February 11, 2005Date of Patent: January 22, 2008Inventor: Brian Steven Ahern

Patent number: 7320302Abstract: The technique of the present invention produces a first fuel-air mixture containing a first fuel and the air at a specific ratio, which does not allow for auto ignition of the first fuel-air mixture by simple compression, in a combustion chamber. The technique then injects a second fuel, which has a higher octane value than that of the first fuel, into a partial area of the combustion chamber, so as to produce a second fuel-air mixture. The technique ignites the second fuel-air mixture for combustion, so as to compress and auto-ignite the first fuel-air mixture. The second fuel has the higher octane value, so that a combustion start timing of the second fuel-air mixture is reliably regulated by ignition. Namely the technique positively controls the timing of auto ignition of the first fuel-air mixture. Setting an adequate value to the ignition timing thus effectively prevents the occurrence of knocking in an internal combustion engine that adopts a premix compression ignition combustion system.Type: GrantFiled: October 31, 2006Date of Patent: January 22, 2008Assignee: Toyota Jidosha Kabushiki KaishaInventor: Tatsuo Kobayashi

Patent number: 7320315Abstract: A butterfly valve restricts flow passage areas of a purge passage and a blow-by gas passage by the same degree. A first pressure sensor detects variation in pressure of the purge gas, which is generated by the butterfly valve. A second pressure sensor detects variation in pressure of the blow-by gas, which is generated by the butterfly valve. Since a fuel vapor concentration of the blow-by gas is lower than that of the purge gas, the blow-by gas can be treated as air of 100%. Hence, the fuel vapor concentration is calculated based on the variations in pressure detected by the first pressure sensor and the second pressure sensor.Type: GrantFiled: January 30, 2007Date of Patent: January 22, 2008Assignees: Denso Corporation, Nippon Soken, Inc.Inventors: Noriyasu Amano, Hideaki Itakura, Makoto Otsubo, Kazuhiro Hayashi, Shinsuke Takakura

Patent number: 7320320Abstract: Methods and apparatus for determining the occurrence of an apnea, patency and/or partial obstruction of the airway are disclosed. Respiratory air flow from a patient is measured to give an air flow signal. The determination of an apnea is performed by calculating the variance of the air flow signal over a moving time window and comparing the variance with a threshold value. One determination of partial obstruction of the airway is performed by detecting the inspiratory part of the air flow signal, scaling it to unity duration and area and calculating an index value of the amplitude of the scaled signal over a mid-portion. Alternatively, the index value is a measure of the flatness of the air flow signal over the mid-portion.Type: GrantFiled: December 15, 2003Date of Patent: January 22, 2008Assignee: ResMed LimitedInventor: Michael Berthon-Jones

Patent number: 7320322Abstract: The valve of the present invention provides a one-piece valve stem piston having a piston head and a piston stem. The piston head has a larger diameter than the piston stem. The stem incorporates only a single sliding O-ring in the area that seals the gas in the valve cylinder bore. The valve blocks gas flow by sealing against the positioning each O-ring over the gas flow port. This provides the valve with a low sliding friction upon piston movement. Pilot control air pressure is reduced because of the lower friction and due to the air operating on the larger surface area of the piston head. All materials in the construction of the valve are non-metallic.Type: GrantFiled: April 21, 2004Date of Patent: January 22, 2008Assignee: Medi-Physics, Inc.Inventor: John Manhard
