Patent number: 10617832Abstract: An adapter for delivering an atomized spray from a syringe. The adapter includes an adapter guide including a side wall, an interior surface of the side wall defining a through-bore and a shoulder in the through-bore. A pin guide is located in the through-bore. The pin guide includes a seat and a sleeve extending from the seat. A spring positioned around the pin guide sleeve and between the pin guide seat and the shoulder, wherein the spring and the sleeve provide a passageway there between. A pin extends from the pin guide seat and through the passageway. Affixing the adapter onto a syringe provides an atomizing delivery device. A method of dispensing an atomized spray from a syringe is provided by affixing the adapter to the syringe.Type: GrantFiled: November 22, 2017Date of Patent: April 14, 2020Assignee: Southwest Research InstituteInventors: Barrett Wade Mangold, Terrence Francis Alger, II, Albert M. Zwiener

Patent number: 8291891Abstract: Improved exhaust gas recirculation system and methods that use one or more of the engine's cylinders as dedicated EGR cylinders. All of the exhaust from the dedicated EGR cylinders is recirculated back to the engine intake. Thus, the EGR rate is constant, but the EGR mass flow may be controlled by adjusting the air-fuel ratio of the dedicated EGR cylinders or by using various variable valve timing techniques.Type: GrantFiled: June 17, 2008Date of Patent: October 23, 2012Assignee: Southwest Research InstituteInventors: Terrence Francis Alger, II, Barrett Wade Mangold, Jess Witman Gingrich, Darius Mehta

Patent number: 8129320Abstract: The present disclosure relates to lubricant oil compositions formed from base stock oils to optimize internal combustion engine performance. Base stock oils are identified that have selected cetane number characteristics and relatively reduced reactivity to improve their associated combustion characteristics and reduce engine knock without the need to modify the engine fuel or engine parameters such as compression ratio and/or ignition timing. The base stocks may specifically include esters of dicarboxylic acids, esters of trimellitic anhydride and/or alklyated naphthalene compounds.Type: GrantFiled: September 10, 2009Date of Patent: March 6, 2012Assignee: Southwest Research InstituteInventors: Manfred Amann, Terrence Francis Alger, II, Thomas W. Ryan, III

Patent number: 7822531Abstract: An aspect of the present disclosure relates to a method and system for reducing emissions and improving knock-tolerance in an engine. Air, including exhaust gas present at levels greater than 20% by total air mass, may be introduced into a combustion chamber having a volume including a piston and a cylinder head. A first amount of fuel and a second amount of fuel may be directly injected into the combustion chamber at various points during the cycle, wherein the ratio of the air, including the exhaust gas, to the first and second amounts of fuel is 14.0:1 to 15.0:1. The first and second amounts of fuel may then be ignited. An electronic control unit may be utilized to time the injections and control the introduction of exhaust gas.Type: GrantFiled: April 28, 2008Date of Patent: October 26, 2010Assignee: Southwest Research InstituteInventors: Terrence Francis Alger, II, Charles Edward Roberts, Jr., Darius Mehta

Patent number: 7741762Abstract: A dual-electrode spark igniter (spark plug), which has two electrodes extending from the plug body. During a spark event, electricity flows across a first spark gap from a first electrode to a second electrode. Electricity also flows across a second spark gap from the second electrode to ground.Type: GrantFiled: May 25, 2006Date of Patent: June 22, 2010Assignee: Southwest Research InstituteInventors: Terrence Francis Alger, II, Barrett Wade Mangold

Publication number: 20090126710Abstract: An electrical circuit for extending the duration of the spark provided by a spark plug. Instead of a single coil (and a single pair of windings), a dual coil unit is used. The dual coil unit may be operated in a “multi-strike” mode in which the discharge of each coil is shortened and offset from that of the other coil. This provides an effective spark for an extended duration.Type: ApplicationFiled: November 21, 2007Publication date: May 21, 2009Applicant: Southwest Research InstituteInventors: Terrence Francis Alger, II, Kane Tyler, Barrett Wade Mangold

Patent number: 7495447Abstract: A method and system for evaluating the durability of spark plugs. A test system simulates the pressure, temperature, and exhaust flow of an internal combustion engine, and has a test chamber in which these simulated conditions exist. A number of spark plugs are installed in the test chamber and are cycled through a desired ignition cycle. The test chamber temperature and pressure may be precisely controlled, as well as the duty cycle of spark events.Type: GrantFiled: August 31, 2006Date of Patent: February 24, 2009Assignee: Southwest Research InstituteInventors: Terrence Francis Alger, II, Darius Mehta, Charles Edward Roberts, Jr.

Patent number: 7240670Abstract: A follow-on circuit for extending the duration of the spark provided by a spark plug. The circuit is connected between the coil secondary and the spark gap, and has a capacitor that discharges to the point of connection through a resistor and inductor. The resistor may be made variable to control the amount and duration of the follow-on current, and hence the energy and duration of the spark event. The circuit may also be used with other ignitors and non-coil ignition circuits.Type: GrantFiled: May 25, 2006Date of Patent: July 10, 2007Assignee: Southwest Research InstituteInventors: Terrence Francis Alger, II, Barrett Wade Mangold
