Patent number: 6729128Abstract: Carbon-containing suspended particulates in exhaust gas from an internal combustion engine are collected by a heat-resistant filter, and are burned on the filter. It is determined whether there is a need to increase the temperature of the heat-resistant filter. If it is necessary to increase the filter temperature, the dynamic pressure on the filter is increased. The conceivable cases where a filter temperature increase is needed includes a case where the exhaust gas temperature is low, a case where the filter is clogged to some extent, etc. If the dynamic pressure on the heat-resistant filter is increased, the filter temperature rises. Therefore, particulates can be effectively removed from exhaust gas while the clogging of the heat-resistant filter is avoided.Type: GrantFiled: June 17, 2002Date of Patent: May 4, 2004Assignees: Toyota Jidosha Kabushiki Kaisha, Nippon Soken, IncorporatedInventors: Kazuhiko Shiratani, Naohisa Oyama, Yoshitada Kodama

Patent number: 6729132Abstract: A bi-directional braking assembly for a vehicle includes a hydraulic booster assembly for applying proportional fluid pressure to a brake assembly and is actuated by a forward pedal. A master cylinder actuated by a rear pedal communicates fluid to the hydraulic booster assembly through a hydraulic booster valve. The hydraulic booster valve includes a piston movable to regulate hydraulic pressure in response to actuation of first and second plungers. The second plunger is movable along an axis separate from the first plunger in response to actuation of a master cylinder by a rear pedal. The master cylinder provides pressure to the booster valve assembly that acts on an area between the first and second plunger assemblies to move the second plunger away from the first plunger to actuate and move the booster piston within the valve.Type: GrantFiled: July 19, 2002Date of Patent: May 4, 2004Assignee: Meritor Heavy Vehicle Braking Systems (UK) LtdInventors: Mark Batchelor, Michael Williamson

Patent number: 6729133Abstract: A heat exchange cooling system for an internal combustion engine co-generation plant, which allows exhaust recycled gas combustion while maintaining lower head temperatures to reduce thermal NOx emissions while delivering increased process/utility heat to a proximate co-generation client, is provided. The cooling system has two cooling loops with different flow rates: one through the engine and the second through exhaust manifolds, such that higher engine block flow resulting in cooler head temperatures is provided, while allowing higher temperature coolant to flow through exhaust exchangers, such that when the two coolant flows converge at a process/utility heat exchanger for heating co-generation client liquid, the combined flows substantially increase the transferred heat.Type: GrantFiled: February 3, 2003Date of Patent: May 4, 2004Assignee: Chapeau, Inc.Inventors: Richard L. Sorter, Gerald H. Dorn

Patent number: 6729134Abstract: Variable geometry turbochargers include a turbine housing having an exhaust gas inlet and outlet, a volute connected to the inlet, and typically a nozzle wall adjacent the volute. The turbine housing includes a bypass exhaust gas flow port disposed internally therein having an inlet opening positioned upstream from the turbine wheel, and a outlet opening positioned downstream from the turbine wheel. The inlet opening is exposed for facilitating bypass exhaust gas flow through the turbocharger when a respective vane is actuated or moved into an open position. The turbine housing may also include a specially configured nozzle wall terminal edge designed to work with vanes having a recessed underside surface to permit additional bypass exhaust gas flow within the turbocharger when the vanes are actuated in an open position.Type: GrantFiled: June 24, 2002Date of Patent: May 4, 2004Assignee: Honeywell International Inc.Inventors: Steven Don Arnold, Kevin P. Slupski, Zandrie J. Wiersma, Kelvin K. Bunsirisert

Patent number: 6729135Abstract: A recirculation system for circulating distillate during gas fuel operation so as to reduce or eliminate distillate carbon formation. The recirculation system keeps the distillate's temperature below the carbon formation limit by circulating the distillate back to a heat sink and/or heat exchanger. The recirculating flow also exercises the flow dividers' gears without having to perform fuel transfers. Further, the system evacuates air from the liquid fuel lines to further decrease the likelihood of carbonaceous residue forming on any interior surfaces that are actually exposed to distillate.Type: GrantFiled: December 12, 2002Date of Patent: May 4, 2004Assignee: General Electric CompanyInventors: Eric Steven Norris, Steven William Backman, Robert Joseph Iasillo, Kevin Jon O'Dell, David J. Van Buren, Michael J. Alexander, Mark Andrew Cournoyer, Mark Andrew Johnson, Colin Wilkes

Patent number: 6729136Abstract: A power plant for a use device wherein liquid nitrogen and a heated transfer fluid are alternately used to expand and contract a liquid metal like mercury to drive a piston, a crankshaft, and subsequent drive apparatus. A control device is timed with operation of the piston to control various solenoid valves and pumps to cause liquid nitrogen to flow into a jacket around a reservoir containing the liquid metal thereby causing it to cool and move the piston in a return stroke. When appropriate, the heated transfer fluid is pumped into a different enclosure of the jacket to force out remaining nitrogen and thereby to heat the liquid metal and move the piston in a power stroke. The process continues so as to provide continuous power to the use device.Type: GrantFiled: June 18, 2002Date of Patent: May 4, 2004Inventor: Farouk Dakhil

Patent number: 6729137Abstract: A closed loop vapor cycle generated by a special device formed by heat transfer and a vapor expander means it is utilized to convert waste heat from conventional power systems into additional thermodynamic work, thereby improving the overall power system efficiency. Superheated vapor (i.e. steam) is instantaneously produced inside special energy transfer means where waste heat is converted into fluid energy with desired thermodynamic properties. The superheated vapor is then converted into mechanical energy through special work-producing units (expanders), thereby returning a significant fraction of the energy contained in the waste heat to the power system.Type: GrantFiled: February 6, 2002Date of Patent: May 4, 2004Inventor: Claudio Filippone
