Publication number: 20090133666Abstract: A homogenous charge compression ignition barrel engine includes an engine housing, a power shaft and a plurality of cylinders surrounding the shaft. Each cylinder has a closed end and an open end. An intake system introduces a combustible mixture into the cylinders. A track is disposed between a first end of the housing and the open ends of the cylinders. The track has a cam surface that longitudinally undulates with respect to the open ends of the cylinders. A piston is moveably disposed in each of the cylinders and is in mechanical communication with the cam surface of the track such that as the cylinders and the track move with respect to each other, the pistons reciprocate within the cylinders. Each cylinder is operable to compress a combustible mixture until the mixture auto ignites, without the introduction of a spark.Type: ApplicationFiled: November 20, 2008Publication date: May 28, 2009Applicant: Thomas Engine Company, LLCInventor: Charles Russell Thomas

Patent number: 7469662Abstract: The relative combustion phasing of a homogenous charge compression ignition engine is controlled by controlling the introduction of ions and free radicals to cylinders in the engine. The engine has an engine housing with at least a first and second cylinder and an intake system that introduces a combustible mixture of air and fuel to the cylinders. A piston is disposed in each of the cylinders and is operable to compress a combustible mixture until the mixture auto ignites, without the introduction of a spark.Type: GrantFiled: October 21, 2005Date of Patent: December 30, 2008Assignee: Thomas Engine Company, LLCInventor: Charles Russell Thomas

Patent number: 7464673Abstract: An internal combustion barrel engine includes an engine housing and an elongated power shaft. A combustion cylinder and a guide cylinder are spaced apart and disposed on a common cylinder axis. A double-ended piston includes a combustion end disposed in the combustion cylinder so as to define a combustion chamber between the combustion end and the closed end of the combustion cylinder. A guide end is disposed in the guide cylinder. Combustion occurs only in the combustion cylinder and does not occur in the guide cylinder.Type: GrantFiled: August 14, 2006Date of Patent: December 16, 2008Assignee: Thomas Engine Company, LLCInventors: Charles Russell Thomas, Bret R. Hauser, David P. Branyon

Patent number: 6986342Abstract: A homogenous charge compression ignition barrel engine includes an engine housing with a first and second end. An elongated power shaft is longitudinally disposed in the engine housing and defines a longitudinal axis of the engine. A plurality of cylinders surround the longitudinal axis with each cylinder having a closed end and an open end. Each cylinder has a central axis. The open ends of the cylinders are each generally directed toward the first end of the housing. An intake system is operable to introduce a combustible mixture of air and fuel into each of the cylinders. A track is disposed between the first end of the housing and the open ends of the cylinders such that a portion of the track is disposed generally in alignment with the central axis of each of the cylinders. The track has a cam surface that longitudinally undulates with respect to the open ends of the cylinders. A portion of the cam surface is disposed generally in alignment with the central axis of each of the cylinders.Type: GrantFiled: March 2, 2004Date of Patent: January 17, 2006Assignee: Thomas Engine CopanyInventor: Charles Russell Thomas

Patent number: 6834636Abstract: An internal combustion barrel engine includes an engine housing with a first and second end. An elongated power shaft is longitudinally disposed in the engine housing and defines a longitudinal axis. A combustion cylinder and a guide cylinder are spaced apart and disposed on a common cylinder axis that is generally parallel to the central axis. The cylinders each have an inner end and an outer end, with the inner ends being closer to each other. The outer end of the combustion cylinder is closed. An intake system is operable to introduce a mixture of air and/or fuel into the combustion cylinder. A track is supported between the inner ends of the cylinders and has an undulating cam surface. The track is moveable such that the portion of the cam surface most directly between the cylinders undulates toward and away from the inner end of the combustion cylinder.Type: GrantFiled: April 29, 2003Date of Patent: December 28, 2004Assignee: Thomas Engine CompanyInventors: Charles Russell Thomas, Bret R. Hauser, David P. Branyon
