The backflow preventer (20) has: a casing (41) formed by locally expanding the cross-sectional area of the air intake pathway; and an inner tube (42) substantially constructing a duct for the mainstream of air intake. The inner tube (42) is supported by a flange portion (50) and the downstream end (42a) opens within the casing (41). During backflow when the bypass pathway (17) opens, a portion of the intake air enters into an exit-side space section (55), and the flow is prevented by the flange portion (50). Consequently, reverse flow is suppressed.Type: ApplicationFiled: August 6, 2014Publication date: August 18, 2016Inventors: Takeshi OOKAWA, Kiyoshi IKEGAYA

Publication number: 20160237882Abstract: A system having an engine is provided. The system includes a high pressure (HP) turbocharger and a low pressure (LP) turbocharger connected in series with each other. The system also includes a first valve assembly configured to selectively bypass at least a portion of the exhaust from the engine to the LP turbocharger. The system also includes a storage tank configured to store a pressurized fluid and configured to be in fluid communication with the HP turbocharger and the LP turbocharger. The system further includes a second valve assembly in fluid communication with the storage tank, the HP turbocharger and the LP turbocharger. The system also includes a controller operatively coupled to the first valve assembly and the second valve assembly. The controller is configured to selectively operate the first valve assembly and the second valve assembly based on a change in a load requirement on the engine.Type: ApplicationFiled: April 29, 2016Publication date: August 18, 2016Applicant: Caterpillar Inc.Inventors: Xinyu Ge, Yongli Qi

Publication number: 20160237883Abstract: A bypass mechanism is disclosed for use with a turbocharger. The bypass mechanism may have an exhaust passage formed by at least a first wall, and a bypass manifold formed by at least a second wall surrounding the exhaust passage and including a space between the first wall and the second wall. The bypass mechanism may further have at least one opening in the first wall fluidly connecting the exhaust passage with the space. At least one valve is configured to open and close the opening to selectively allow exhaust gas to pass from the exhaust passage to the space through the at least one opening. The space may be fluidly connected to at least one entry passage of an exhaust stack. In addition, the at least one opening and the at least one entry passage may be positioned on opposite sides of the exhaust passage.Type: ApplicationFiled: February 17, 2015Publication date: August 18, 2016Applicant: ELECTRO-MOTIVE DIESEL, INC.Inventors: Gary R.

Publication number: 20160237885Abstract: A supercharger constructed in accordance to one example of the present disclosure can include a shaft portion connected to a pulley. A pair of supercharger rotors can be arranged for concurrent rotation with respective rotor shafts. A clutch rotor can be mounted to the shaft portion. The clutch rotor can rotate around a longitudinal axis. A clutch armature can be mounted to a drive shaft and unconnected to the shaft portion. The clutch armature can be configured to rotate around the longitudinal axis. The clutch rotor and the clutch armature can selectively cooperate in an engaged position and a disengaged position. In the engaged position, the clutch rotor and the clutch armature rotate together. An electric motor can have an output that provides a rotational input to one of the rotor shafts.Type: ApplicationFiled: April 28, 2016Publication date: August 18, 2016Inventors: Matthew J.

Publication number: 20160237886Abstract: An engine including at least two piston and cylinder assemblies that, when operating with a fuel savings cycle, establish at the end of the simultaneous compression strokes a charge of compressed air in one cylinder of one assembly and a charge of compressed air fuel mixture in the other cylinder of the other assembly. When the air fuel mixture is ignited, the high pressure conditions in the other cylinder are immediately communicated through a passage to the one cylinder to accomplish a double expansion during the simultaneous power drive strokes thus using much of the pressure energy before exhaust occurs by the pistons themselves. The improvement comprises changing the other assembly which has the charge of compressed air fuel mixture therein between the two piston and cylinder assemblies in a predetermined pattern as, for example, an operative alternation between the two piston and cylinder assembles.Type: ApplicationFiled: April 4, 2016Publication date: August 18, 2016Inventor: Raymond F.
