Patent number: 9803571Abstract: A method, used with dual-fuel engine, of controlling the amount of gaseous fuel delivered to the engine. At operating conditions that result in an equivalence ratio below a predetermined threshold (which typically occur at mid or part loads), it is determined whether better performance and/or lower emissions can be achieved by reducing gaseous fuel to some cylinders and increasing gaseous fuel to others. Typically, the gaseous fuel is reduced to zero to a number of cylinders and increased to others, with the increase resulting in an equivalence ratio that will provide improved emissions and efficiency and the desired engine output.Type: GrantFiled: January 23, 2016Date of Patent: October 31, 2017Assignee: SOUTHWEST RESEARCH INSTITUTEInventors: John C. Hedrick, David P. Branyon, Timothy J. Callahan, Jeremy D. Eubanks, Ryan C. Roecker, Garrett L. Anderson

Patent number: 8006656Abstract: An engine has a crankshaft, rotating about a crankshaft axis of the engine. An expansion piston is slidably received within an expansion cylinder and operatively connected to the crankshaft such that the expansion piston reciprocates through an expansion stroke and an exhaust stroke of a four stroke cycle during a single rotation of the crankshaft. A compression piston is slidably received within a compression cylinder and operatively connected to the crankshaft such that the compression piston reciprocates through an intake stroke and a compression stroke of the same four stroke cycle during the same rotation of the crankshaft. A ratio of cylinder volumes from BDC to TDC for either one of the expansion cylinder and compression cylinder is fixed at substantially 26 to 1 or greater.Type: GrantFiled: April 18, 2009Date of Patent: August 30, 2011Assignee: Scuderi Group, LLCInventors: David P. Branyon, Jeremy D. Eubanks
