Publication number: 20020189235Abstract: A system and method for optimizing the regeneration cycle of an emission control device, such as a lean NOx trap, is disclosed wherein the device is filled to a predetermined fraction of its existing capacity and is then completely emptied during a device purge. As device capacity is substantially reduced, as indicated by the actual fill time becoming equal to or less than a predetermined minimum fill time, a device desulfation event is performed to attempt to restore device capacity. A programmed computer controls the fill and purge times based on the amplitude of the voltage of a switching-type oxygen sensor and the time response of the sensor.

Publication number: 20020189236Abstract: A system and method is provided for controlling a lean-burn engine whose exhaust gas is directed through an exhaust treatment system which includes an emission control device that alternately stores and releases a selected constituent of the exhaust gas, such as NOx, based on engine operating conditions, and a downstream NOx sensor. The system estimates the concentration of NOx flowing into the device based on engine operating conditions while determining a value for the concentration of NOx flowing out of the device based upon the output signal generated by NOx sensor. A device purge event is scheduled when the device efficiency, calculated based on the NOx concentrations flowing into and out of the device, falls below a predetermined minimum efficiency value. The length of a purge event is determined as a function of an accumulated measure based on the difference between the NOx concentrations into and out of the device.Type: ApplicationFiled: June 19, 2001Publication date: December 19, 2002Inventors: Jeffrey Scott Hepburn, JoAnne Temple, Mark Allen Dearth

Publication number: 20020189237Abstract: A more precise method for determining the oxygen storage capacity of an exhaust gas aftertreatment device is presented. The most accurate capacity estimate is obtained while the engine is idling or during low load operation. The capacity is determined by integrating the output of an oxygen sensor located downstream of the device during a period of time that it takes to store more than a predetermined amount of oxygen in the device. The overall LNT efficiency can then be inferred from its oxygen storage capacity. This method allows for improved emission control and fuel economy.Type: ApplicationFiled: June 19, 2001Publication date: December 19, 2002Inventors: David Karl Bidner, Grant Alan Ingram, Gopichandra Surnilla

Publication number: 20020189239Abstract: A method of reducing emissions in the exhaust gases of an internal combustion engine that has at least one cylinder to which an air/fuel mixture is supplied when a crankshaft of the internal combustion engine is rotated, at least one intake valve, at least one exhaust valve, and a piston reciprocating between a top dead-center position and a bottom dead-center position in the cylinder. The method comprises the following steps: an air/fuel mixture with a lambda value greater than 1 is supplied to the cylinder, an electric motor/generator connected to the crankshaft maintains an essentially constant predetermined speed of the crankshaft, and the exhaust valve is controlled so that it opens before the piston has passed the bottom dead-center position is disclosed.Type: ApplicationFiled: December 11, 2001Publication date: December 19, 2002Applicant: Volvo Car CorporationInventors: Goran Almkvist, Karin Thorn

Publication number: 20020189241Abstract: A method and system for controlling the operation of an internal combustion engine, wherein exhaust gas generated by the engine is directed through an emission control device, includes determining instantaneous rates of storage for a constituent of the exhaust gas, such as NOx, as well as the capacity reduction of the device to store the exhaust gas constituent as a function of a calculated value representing an amount of SOx which has accumulated in the device since a prior device-regeneration (desulfation) event. The calculated accumulated SOx value is also preferably used to schedule a device-regeneration event, as when the calculated accumulated SOx value exceeds a predetermined threshold value.Type: ApplicationFiled: June 19, 2001Publication date: December 19, 2002Inventors: David George Farmer, Gopichandra Surnilla, Michael John Cullen

Publication number: 20020189242Abstract: An exhaust gas treatment system for an internal combustion engine includes a three-way catalyst and a NOx device located downstream of the three-way catalyst. The device is preconditioned for emissions reduction at engine operating conditions about stoichiometry by substantially filling the device with oxygen and NOx; and purging stored oxygen and stored NOx from only an upstream portion of the device, whereupon the upstream portion of the device operates to store oxygen and NOx during subsequent lean transients while the downstream portion of the device operates to reduce excess HC and CO during subsequent rich transients.Type: ApplicationFiled: June 19, 2001Publication date: December 19, 2002Inventors: David George Farmer, Gopichandra Surnilla

The invention also extends to combustion of other animal/vegetable-based fats and oils, particularly waste cooking oils which are at risk of contamination by toxic chemicals which may potentially enter the food chain. The heat and power produced by the engine may then be used to generate electricity. In accordance with the invention, the tallow, etc. is combusted in an enriched oxygen atmosphere in the combustion chamber of the engine.Type: ApplicationFiled: May 16, 2002Publication date: December 19, 2002Inventor: John McNeil
