Publication number: 20140196703Abstract: An engine is provided that includes an exhaust gas recirculation (EGR) conduit in fluidic communication with a first exhaust valve in a cylinder and an intake system, an exhaust conduit in fluidic communication with a second exhaust valve in the cylinder and an emission control device. During operation with the first valve active and the second valve deactivated, a fixed EGR level can be provided.

Patent number: 7596159Abstract: A semiconductor laser diode comprises a p-n junction. The p-n junction comprises a substrate, an n-type semiconductor layer, a p-type semiconductor layer, and a quantum well. The quantum well is disposed between the n-type semiconductor layer and the p-type semiconductor layer. The substrate is formed from a first material system, the n-type semiconductor layer is formed from a second material system, the p-type semiconductor layer is formed from a third material system, and the quantum well is formed from a fourth material system. The second material system is different from the third material system. The second material system and the third material system are selected such that there is an increase in the rate of recombinations of the electrons from the n-type semiconductor layer and the holes from the p-type semiconductor layer in the quantum well. This results in a lower turn-on voltage for the semiconductor laser diode.Type: GrantFiled: October 11, 2005Date of Patent: September 29, 2009Assignee: Alfalight Inc.Inventors: Manoj Kanskar, Thomas Lester Earles, Eric Warren Stiers

Patent number: 6805079Abstract: A system for controlling electromechanical of an internal combustion has a valve-closing electromagnet for attracting the armature coupled to the valve to close the valve, a valve-opening electromagnet for attracting the armature to open the valve, a valve-opening spring for biasing the valve open, and a valve-closing spring for biasing the valve closed. The method includes de-energizing the valve-closing electromagnet for a predetermined time, enabling the valve to oscillate by the valve springs, and then energizing the valve-closing electromagnet to close the valve. Consequently, only the valve-closing electromagnet is energized to open and close the valve. The valve biasing springs force the valve to a location at which the valve-closing electromagnet can close the valve. This provides an electrical energy over prior methods in which both the valve-opening and valve-closing electromagnets are energized to actuate the valve.Type: GrantFiled: November 2, 2001Date of Patent: October 19, 2004Inventors: Diana D. Brehob, Eric Warren Curtis, William Francis Stockhausen

Patent number: 6532919Abstract: An electromagnetic valve actuator (EVA) for actuating movement of a valve in a vehicle engine includes a valve assembly operatively connected to the valve for movement therewith. The valve assembly includes a shaft connected to the valve. Two armature plates are operatively associated with the shaft, and each armature plate includes a permanent magnet. An electromagnetic coil is positioned between the two armature plates for selectively electromagnetically pushing and pulling the armature plates. Two springs are engaged with the two armature plates, respectively, for biasing the armature plates in opposing directions. The permanent magnets are operative to assist the electromagnetic coil in holding the valve in a desired position to reduce power consumption or assisting in repelling the armature for accelerating valve opening or closing.Type: GrantFiled: December 8, 2000Date of Patent: March 18, 2003Assignee: Ford Global Technologies, Inc.Inventors: Eric Warren Curtis, Mohammad Haghgooie, Thomas William Megli
