Publication number: 20170074756Abstract: An exhaust sampling system for an engine is provided. The exhaust sampling system may include a source of exhaust gas, an exhaust collection unit including at least one collection bag that selectively receives the exhaust gas, and a sample probe in fluid communication with the source of exhaust gas that selectively supplies the at least one collection bag with the exhaust gas. The exhaust sampling system may also include a controller that permits flow of the exhaust gas from the sample probe to the at least one collection bag in a first state and prevents flow of the exhaust gas from the sample probe to the at least one collection bag in a second state. The controller may determine an extraction rate of the sample probe based on an ON time of the engine during a test phase.Type: ApplicationFiled: November 14, 2016Publication date: March 16, 2017Inventors: James Patrick WILLIAMSON, William Martin SILVIS

Patent number: 9518897Abstract: An exhaust sampling system for an engine is provided. The exhaust sampling system may include a source of exhaust gas, an exhaust collection unit including at least one collection bag that selectively receives the exhaust gas, and a first sample probe in fluid communication with the source of exhaust gas that selectively supplies the at least one collection bag with the exhaust gas at an extraction rate. The exhaust sampling system may also include a controller that permits flow of the exhaust gas from the first sample probe to the at least one collection bag in a first state and prevents flow of the exhaust gas from the first sample probe to the at least one collection bag in a second state. The controller may control the extraction rate of the first sample probe based on a time during a test phase at which the engine is switched to an ON state.Type: GrantFiled: May 28, 2013Date of Patent: December 13, 2016Assignee: AVL TEST SYSTEMS, INC.Inventors: James Patrick Williamson, William Martin Silvis

Publication number: 20160209300Abstract: Disclosed is an exhaust sampling system including a plurality of exhaust sampling system zones. The zones are, at least, a sampling conduit, a fill circuit, and a read circuit. A controller is programmed to predict a minimum dilution ratio to avoid condensation in one of the exhaust sampling system zones. The controller is further programmed to run a test procedure in which a sample of exhaust is diluted with a make-up gas at a selected minimum dilution ratio that is greater than or equal to the predicted minimum dilution ratio. Further disclosed are methods of predicting whether condensation occurs during a test procedure.Type: ApplicationFiled: March 25, 2016Publication date: July 21, 2016Inventors: William Martin SILVIS, James Patrick WILLIAMSON, Gerald MAREK, Douglas Edward MILLER

Publication number: 20150338320Abstract: An engine emissions test system according to the principles of the present disclosure includes a sampling conduit, at least one sample bag, a read circuit, and a fill circuit. The sampling conduit is configured to receive exhaust from an engine. The at least one sample bag is configured to store a sample of exhaust. The read circuit is configured to communicate the stored sample of exhaust between the at least one sample bag and an analyzer. The fill circuit includes a fill gas line configured to provide a fill gas to be mixed with the sample of exhaust. The fill gas line extends between a fill gas source and the read circuit.Type: ApplicationFiled: August 3, 2015Publication date: November 26, 2015Inventors: William Martin SILVIS, James Patrick WILLIAMSON

Patent number: 8863740Abstract: A heat pipe comprises an evaporator section 5 having a radiation absorbing plate 6 a portion of an elongate tube 7, and a condenser section 10 at a distal end of the elongate tube 7 remote from the evaporator section 5. A flow control valve 20 is provided between the evaporator section 5 and the condenser section 10 to selectively interrupt communication between said sections when the temperature within the condenser section 10 exceeds a predetermined maximum. A temperature sensitive member, (coil of memory metal 34?, or discs 34?) acts between a support plate 26 and a seat 36 located on a valve pintle 30 to urge the valve head 22 towards the valve seat 24 when the temperature of the temperature sensitive member 34 exceeds a predetermined limit. A return spring 38 is provided to bias the valve head 22 away from the valve seat 24.Type: GrantFiled: April 7, 2008Date of Patent: October 21, 2014Assignee: Kingspan Holdings (IRL) LimitedInventors: Thomas Patrick Williamson, Boris Bauer, Paul Thomas McEntee
