Patent number: 8800264Abstract: An exhaust assembly for a vehicle includes an exhaust pipe through which an exhaust gas flows substantially in a first direction. The exhaust pipe includes a central region. The assembly also includes a sensor in fluid communication with the exhaust pipe and an elongated tube extending from a first end toward a second end and disposed at least partially within the exhaust pipe. The first end of the tube receives at least a portion of the sensor. The tube includes an inlet opening and an outlet opening. The inlet opening generally faces the exhaust gas flowing within the central region in the first direction so that some of the exhaust gas flowing in the central region enters the inlet opening. The tube directs the exhaust gas within the tube toward the sensor, and the exhaust gas within the tube flows out of the tube through the outlet opening.Type: GrantFiled: January 11, 2013Date of Patent: August 12, 2014Assignee: Chrysler Group LLCInventors: Raymond J. Sullivan, Mark E. McKackin, Richard L. Lewis, William L. Laga, Charles S. Payton

The first end of the tube receives at least a portion of the sensor. The tube includes an inlet opening and an outlet opening. The inlet opening generally faces the exhaust gas flowing within the central region in the first direction so that flow of the exhaust gas in the central region substantially directly enters the inlet opening. The tube directs the exhaust gas within the tube toward the sensor, and the exhaust gas within the tube flows out of the tube through the outlet opening.Type: ApplicationFiled: November 10, 2010Publication date: May 10, 2012Inventors: Mark E.

Patent number: 6256981Abstract: An exhaust system is provided including two catalysts and three oxygen sensors. The second catalyst is disposed downstream of the first catalyst. The first oxygen sensor is disposed upstream of the first catalyst, the second oxygen sensor is disposed downstream of the first catalyst and upstream of the second catalyst, and the third oxygen sensor is disposed downstream of the second catalyst. A goal voltage corresponding to a desired level of oxygen within the exhaust is provided for the third oxygen sensor based on engine RPM and MAP. The engine controller compares the goal voltage to an actual voltage generated by the third oxygen sensor and an error value is obtained and converted into a goal voltage for the second oxygen sensor. The engine controller compares the goal voltage to an actual voltage generated by the second oxygen sensor and an error value is obtained and converted into a goal voltage for the first oxygen sensor.Type: GrantFiled: August 10, 1999Date of Patent: July 10, 2001Assignee: Chrysler CorporationInventors: Raymond J. Sullivan, Bruce H. Teague, Kenneth P. DeGroot, Michael J. Reale

Patent number: 6253541Abstract: An exhaust system is provided including two catalysts and three oxygen sensors. The second catalyst is disposed downstream of the first catalyst. The first oxygen sensor is disposed upstream of the first catalyst, the second oxygen sensor is disposed downstream of the first catalyst and upstream of the second catalyst, and the third oxygen sensor is disposed downstream of the second catalyst. A goal voltage corresponding to a desired level of nitrous oxide and hydrocarbon within the exhaust is provided for the third oxygen sensor. This goal voltage is based on engine RPM and MAP. The engine controller compares the goal voltage to an actual voltage generated by sensing the level of oxygen downstream of the second catalyst. Based on this comparison, an error value between the goal voltage and the actual voltage is obtained. This error value is converted into a goal voltage for the first oxygen sensor.Type: GrantFiled: August 10, 1999Date of Patent: July 3, 2001Assignee: DaimlerChrysler CorporationInventors: Raymond J.

Patent number: 6234153Abstract: A fuel control system is provided including a fuel tank, a purge vapor canister, a vapor line, and a fuel injector connected to an internal combustion engine. A purge vapor canister vent valve seals the purge vapor canister from the atmosphere such that the fuel tank, purge vapor canister, and fuel injector form a closed system. Upon initial starting of the engine, the purge vapor pressure is such that the purge vapor is drawn to the fuel injector from the dome portion of the fuel tank after passing through the purge vapor canister. Simultaneously therewith, the amount of liquid fuel is reducing or increasing by an amount of equally increasing or decreasing, respectively, vapor fuel so that a necessary mass flow rate is achieved to support combustion. As the amount of fuel vapors decreases to a negligible amount, combustion is supported by the atomization of liquid fuel.Type: GrantFiled: October 11, 1999Date of Patent: May 22, 2001Assignee: DaimlerChrysler CorporationInventors: Kenneth P.

Patent number: 6003494Abstract: A method is provided for controlling spark advance based on a fuel modifier. Initially, engine fueling is reduced according to a known dynamic crankshaft fuel control (DCFC) methodology. As a result, the engine tends to run rougher. In response, spark advance is varied based on the overall fuel multiplier reduction from the DCFC methodology. For instance, a look-up table, or mathematical function based on the DCFC multiplier can be utilized as the basis for the spark advance.Type: GrantFiled: August 31, 1998Date of Patent: December 21, 1999Assignee: Chrysler CorporationInventors: Kenneth P. DeGroot, Michael J. Reale, Bruce H. Teague, Raymond J. Sullivan, Dennis A. Soltis

Patent number: 5947088Abstract: A method is provided for enriching a fuel to air ratio in an engine during acceleration based on a known fuel multiplier. Initially, the method retrieves the fuel multiplier from a dynamic crankshaft fuel control (DCFC) system. This system uses the fuel multiplier to reduce the amount of fuel delivered to the engine. When acceleration is desired, the method increases the overall acceleration enrichment values as a function of the DCFC fuel multiplier. Thus, when the vehicle is launched via a throttle tip-in while the DCFC system is active, the acceleration enrichment values are increased thereby improving drivability by having combustion taking place in a richer environment.Type: GrantFiled: August 31, 1998Date of Patent: September 7, 1999Assignee: Chrysler CorporationInventors: Kenneth P. DeGroot, Michael J. Reale, Bruce H. Teague, Raymond J. Sullivan, Dennis A. Soltis
