Patent number: 10458324Abstract: A rotary piston engine having a rotor with an output shaft and a plurality of longitudinally extending cylinder-forming bores, each having a slidable piston disposed therein. The rotor is contained in a housing that contains an elliptical cam track that interacts with the pistons, upon combustion, to cause rotation of the rotor. An opening in the housing end cap admits air into the cylinders on the rear side of the pistons and a port delivers air driven by the rear side of the pistons to an intake port in the side of the housing where, in response to the angular position of the rotor, the air is admitted to the front side of a piston for compression with injected fuel. The compressed fuel-air mixture is ignited and an exhaust port in the side of the housing opens to discharge the products of combustion.Type: GrantFiled: May 19, 2017Date of Patent: October 29, 2019Inventor: Daniel J Edwards

Patent number: 10458325Abstract: A rotary engine includes an insert having a pilot subchamber defined therein and communicating with the internal cavity of the engine. A pilot fuel injector has a tip in communication with the pilot subchamber. An ignition element extends into an element cavity defined through the insert adjacent the pilot subchamber. The element cavity is in communication with the pilot subchamber through a communication opening defined in the insert between the element cavity and the pilot subchamber. The communication opening is smaller than a portion of the ignition element adjacent the communication opening such as to prevent the portion of the ignition element from completely passing through the communication opening upon breaking off of the portion of the ignition element from a remainder of the ignition element. An outer body for a rotary engine and a method of combusting fuel in a rotary engine are also provided.Type: GrantFiled: March 20, 2018Date of Patent: October 29, 2019Assignee: Pratt & Whitney Canada Corp.Inventors: Michael Gaul, Andre Julien, Bruno Villeneuve

Patent number: 10458326Abstract: An internal combustion engine includes a cylinder case that includes a first geartrain disposed on a front end of the cylinder case and a second geartrain disposed on a rear end of the cylinder case. The first geartrain drives a first camshaft, and the second geartrain drives a second camshaft, the first and second camshafts having respective rotational axes that are parallel.Type: GrantFiled: January 27, 2017Date of Patent: October 29, 2019Assignee: Caterpillar Inc.Inventor: Craig P. Hittle

Patent number: 10458327Abstract: In an opposed-piston engine, two or more fuel injectors are mounted to a cylinder for direct side injection into the cylinder. The injectors are controlled so as to inject either a single fuel pulse or a plurality of fuel pulses per cycle of engine operation in order to initiate combustion during varying engine speeds and operating conditions.Type: GrantFiled: August 31, 2018Date of Patent: October 29, 2019Assignee: ACHATES POWER, INC.Inventors: Clark A. Klyza, Fabien G. Redon

Patent number: 10458328Abstract: A combustion pressure sensor has a case member with a joint surface on the side of a tip end and in which an opening portion is provided. A joint surface of a pressure reception member on which a combustion pressure acts is brought into planar contact with the joint surface of the case member so as to block the opening portion. A welding portion joins the joint surfaces to each other. A piezoelectric element stored in the case member converts a pressing force based on the combustion pressure transmitted from the pressure reception member into a signal. On the side of one edge side in at least the one joint surface, the one joint surface is limited to a given depth of welding from the other edge side. A predetermined clearance portion is provided so as to form a predetermined gap with the opposite joint surface and a welding portion is provided which includes at least all the limited joint surface from the other edge side in the one joint surface.Type: GrantFiled: March 25, 2015Date of Patent: October 29, 2019Assignees: CITIZEN FINEDEVICE CO., LTD., CITIZEN WATCH CO., LTD.Inventors: Kazuo Takahashi, Yoshihiko Soga

Patent number: 10458329Abstract: A power generation process for use in a processing unit that includes the steps of: using a regenerator to produce a flue gas stream; removing catalyst particles from the flue gas stream; routing the flue gas stream to a combustor/expander unit after performing the step of removing catalyst particles; and using rotation of the turbine of the combustor/expander unit as a source of rotary power. Preferably, the combustor/expander unit includes a combustion chamber and a power recovery turbine housed within a single casing. In certain embodiments, the flue gas stream is routed between the regenerator and the combustor/expander without passing through a compressor.Type: GrantFiled: March 6, 2014Date of Patent: October 29, 2019Assignee: UOP LLCInventors: Xin X. Zhu, Joao Jorge da Silva Ferreira Alves, Paolo Palmas, Richard A. Johnson, II, Michael R. Van de Cotte

Patent number: 10458330Abstract: A gas turbine engine comprises a fan drive turbine, a fan rotor, and a gear reduction driven by the fan drive turbine to, in turn, drive the gear architecture. A main oil supply system supplies oil to components within the gear reduction, and an auxiliary oil supply system. The auxiliary oil system operates to ensure that the gear reduction will be adequately supplied with lubricant for at least 30 seconds at power should the main oil supply system fail.Type: GrantFiled: January 2, 2015Date of Patent: October 29, 2019Assignee: United Technologies CorporationInventor: William G. Sheridan
