Publication number: 20170211520Abstract: An internal combustion engine includes a variable valvetrain system for improving the range of controllability of the internal EGR technique adjusts the internal EGR lift in a more favorable window and position compared to the internal EGR window typically utilized. In particular, a combined change of lift, phase and duration of the internal EGR lift of the exhaust vale improves the controllability and stability of the desired amount of internal EGR. The present system achieves a high internal EGR capability at low loads and lower back pressure. The system also achieves controllability of internal EGR at high loads without requiring ultra low lifts. The system also allows warm-up of the exhaust after treatment system faster for higher conversion efficiency, reduced HC and NOx engine-out emissions and increased combustion stability.Type: ApplicationFiled: January 21, 2016Publication date: July 27, 2017Inventors: Davide DI NUNNO, Manuel A.

Publication number: 20170211522Abstract: High pressure loop exhaust gas circulation is achieved in an exhaust system (10) of an engine (12) by providing an adjustable valve (100) in an exhaust passage (18) of the engine (12). The valve (100) is configured to control fluid flow through the passage (18) and generate pressure to drive the high pressure exhaust gas recirculation. The valve (100) includes a valve inner surface (110) that has a curvilinear profile when viewed in longitudinal cross section. An actuator (140) is connected to the valve (100), and is configured to move the valve (100) relative to the exhaust passage (18) so as to control exhaust gas pressure within the exhaust passage (18). In some embodiments, a pilot tube (280) is used in combination with the valve (100) to generate high pressure exhaust gas recirculation at the engine (12) intake.Type: ApplicationFiled: August 14, 2015Publication date: July 27, 2017Inventors: DAVID GRABOWSKA, RAJMOHAN CHANDRAMOHANAN

Publication number: 20170211528Abstract: A joint in a system for conducting a fluid has a first duct and a second duct that is coupled together via fasteners. Typically, the fasteners are placed into tabs that are affixed to the ducts and shafts of the fasteners run in the same direction as the duct. When the ducts are plastic and the fasteners are metal, the plastic can creep more than the metal such that the joint fails to seal properly after a period of time. To avoid such a situation, a joint that has fasteners installed at an angle with respect to the ducts is disclosed. The tabs are also angled with respect to the ducts: tabs that form an obtuse angle with one of the ducts mate with tabs on the other duct that form a complementary acute angle. In one embodiment, shafts of pairs of fasteners are roughly perpendicular.Type: ApplicationFiled: January 27, 2016Publication date: July 27, 2017Inventor: Gary Nola
