Publication number: 20170350357Abstract: In metal-on-metal sealing structures, the sealing criteria employed for high pressure liquid fuel does not work when sealing gaseous fuels. An improved method for sealing a gaseous fuel between gaseous fuel conduits in an internal combustion engine comprises forming a contact band between two surfaces of a sealing structure between a first conduit and a second conduit. A width of the contact band is at least equal to the larger of a minimum contact pressure width where contact pressure is at least equal to a predetermined minimum contact pressure; and a minimum yield zone width where at least one of the two surfaces have plastically deformed.Type: ApplicationFiled: December 18, 2015Publication date: December 7, 2017Applicant: Westport Power Inc.Inventors: Alain M.J.

Publication number: 20170350358Abstract: A fuel-injection device has a low-noise and pivotable structure. The fuel-injection device includes at least a fuel injector and a receiving bore in a cylinder head for the fuel-injector, and a decoupling element between a valve housing of the fuel injector and a wall of the receiving bore. The decoupling element is captively situated on the fuel injector prior to its installation in the receiving bore in that a securing ring is mounted below the decoupling element at the outer periphery of the fuel injector and the securing ring is a closed plastic ring. The fuel-injection device is particularly suited for the direct injection of fuel into a combustion chamber of a mixture-compressing internal combustion engine having externally supplied ignition.Type: ApplicationFiled: October 26, 2015Publication date: December 7, 2017Inventors: Johann Bayer, Wilhelm Reinhardt

Publication number: 20170350360Abstract: A stop-start control system for a vehicle includes a camera disposed at the vehicle and having a field of view exterior and forward of the vehicle. A control includes an image processor operable to process image data captured by the camera. Responsive to image processing of captured image data, the control determines the presence of a stopping area ahead of the vehicle and being approached by the vehicle. Responsive to determination of the presence of the stopping area ahead of the vehicle and being approached by the vehicle, and responsive to determination that the driver of the vehicle releases the accelerator pedal of the vehicle so the vehicle is coasting toward the determined stopping area, the control causes the engine to at least partially shut off.Type: ApplicationFiled: June 8, 2017Publication date: December 7, 2017Inventors: Brian J. Tedesco, Sai Sunil Charugundla Gangadhar

Publication number: 20170350361Abstract: In a distribution flow path that allows engine coolant to circulate between an exhaust heat recovery unit and an engine, an upstream flow path on the upstream side of the engine and a downstream flow path on the downstream side of the engine are communicated with each other by means of a bypass flow path to thereby form a short flow path with a shorter flow path length than in a case where the engine coolant that has exited the exhaust heat recovery unit passes through the engine. A valve that can adjust the amount of the engine coolant flowing to the bypass flow path and a short flow path pump are disposed.Type: ApplicationFiled: May 5, 2017Publication date: December 7, 2017Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Toshio MURATA

Publication number: 20170350362Abstract: A system and method for assessing the presence or absence of ignition coil degradation for an ignition system that includes two ignition coils for each spark plug. Ignition coil degradation may be determined without having to monitor ignition coils via specialized hardware circuitry. In one example, degradation of one or more ignition coils may be inferred from cylinder the presence or absence of cylinder misfire.Type: ApplicationFiled: June 3, 2016Publication date: December 7, 2017Inventors: Chris Paul Glugla, Michael Damian Czekala, Garlan J.

Publication number: 20170350363Abstract: An ignition module, ignition system, and method for providing and generating at least two sparks in each cylinder in a single combustion cycle for RPMs over 3,000. The ignition module, system, and method is configured to detect misfires in a spark plug and take measures to alert a user of such misfires and cause an additional spark to occur prior to the completion of the cylinder's power stroke during its combustion cycle. The ignition module, system and method provides for continuous spark at high RPMs and is configured to reduce and/or eliminate engine misfire in excess of about 3,000 RPM for four stroke engines and up to 30,000 RPM for two stroke engines.Type: ApplicationFiled: August 15, 2017Publication date: December 7, 2017Inventors: Tod Ferguson, Ed Browalski, Ron Paul
