Patent number: 9874126Abstract: A particular trap is regenerated without the use of heat. The regeneration is accomplished using a valving mechanism for periodically creating a reverse pressure throughout the entire trap, after the reverse pressure is created controls are operative to start a regeneration cycle by creating a substantially instantaneous reverse pressure drop across the porous walls of the entire trap to dislodge accumulated particulate cake and by causing the filtered exhaust gas to flow back through the porous walls to remove the dislodged particulate from the trap. A settling tank is connected to the exhaust pipe upstream of the trap to receive and store the dislodged particulate. The controls are operative to return the system to its filtering operation. Gaseous effluent from the tank is returned to the exhaust system upstream of the filter to provide a “closed system” in which only filter gas is discharged to atmosphere.Type: GrantFiled: August 2, 2013Date of Patent: January 23, 2018Assignee: Illinois Valley Holding CompanyInventors: Brett Bailey, William Mitchener

Patent number: 7981174Abstract: An exhaust particulate filter for an engine system includes an array of filter cartridges positioned within a shell, each of the cartridges having an electrically powered heating element coupled therewith. Exhaust gases are distributed among the cartridges according to a single distribution pattern, and the filter can be regenerated without diverting, dividing or bypassing exhaust gases from the filter. Other aspects include feedback control and feedforward control of regeneration based on sensing an electrical resistance property of each of the electrically powered heating elements.Type: GrantFiled: November 26, 2007Date of Patent: July 19, 2011Assignee: Caterpillar Inc.Inventors: Brett Bailey, Michael J.

Publication number: 20080314363Abstract: Lower temperature combustion, which may lead to lower emissions, is accomplished by displacing air adjacent to a fuel injector nozzle. Initially, air is compressed in an engine cylinder by moving the engine piston toward top dead center. Air is displaced through a flow passage within the engine cylinder when the engine piston is in the vicinity of top dead center by moving an air displacement actuator. The air displacement actuator includes a member positioned in the combustion chamber that moves with respect to the engine housing and the piston when actuated. This movement causes air to flow through a flow passage, and fuel is injected into the turbulent compressed air flowing through the flow passage. The mixture of air and fuel are compression ignited in the engine cylinder after a brief ignition delay. Lower emissions may be achieved by bringing the air to the fuel prior to ignition, rather than attempting to bring the fuel to the air as in a typical compression ignition engine.Type: ApplicationFiled: June 19, 2007Publication date: December 25, 2008Inventor: Brett Bailey
