Publication number: 20230015517Abstract: A mixing structure can include a body having first conduits, mixture conduits, and second conduits extending through the body to the internal volume. The first conduits may be closer to a first side of the body than the mixture conduits and the second conduits. The second conduits may closer to another side of the body than the first conduits and the mixture conduits. The internal volume may receive liquid streams from an injector. The first conduits and the second conduits may receive gas streams from outside the body. The body may thermally modify the gas streams and entrain the gas streams into the liquid streams in the internal volume. The mixture conduits may be positioned to direct the gas streams entrained into the liquid streams out of the body in directions directed toward the second side of the body and away from the first side of the body.Type: ApplicationFiled: September 26, 2022Publication date: January 19, 2023Inventors: Sreenivasa Rao Gubba, Bhaskar Tamma, Victor Manuel Salazar, Adam Edgar Klingbeil, Thomas Michael Lavertu, Roy James Primus, John Dowell, Kevin Bailey, Kevin McElhaney

Publication number: 20060178800Abstract: A diesel engine (10) wherein both the operating speed of the engine (RPM) and the timing of the fuel injection into the engine (AA) are cooperatively controlled to be responsive to both the temperature and the pressure of the air (30) used for combustion. A controller (44) receives a temperature signal (28), an air pressure signal (36), and a power demand signal (24) and executes control logic to produce a fuel injection control signal (46) and an engine speed control signal (48) for controlling a fuel injection system (16). A control strategy based on engine inlet air temperature and pressure or manifold air density may be useful for variable speed and power applications. For applications with discreet speed and power points, such as a locomotive, a speed and timing control strategy based on ambient temperature and pressure is useful for maximizing power during high altitude and/or high ambient/inlet air temperature operation.Type: ApplicationFiled: January 31, 2006Publication date: August 10, 2006Inventors: Gong Chen, Richard McGowan, Donald Melpolder, Shawn Gallagher, John Dowell, Kyle Stott

Publication number: 20060086327Abstract: A locomotive diesel engine, having a cylinder liner and a separate water jacket surrounding the cylinder liner, with a portion of the water jacket being positioned between the cylinder liner and the engine frame, where the cylinder liner is supported by the water jacket. An external shoulder on the cylinder liner can be supported by an internal flange in the water jacket, thereby eliminating direct contact between the cylinder liner and the engine frame. A coolant passage can be provided between the water jacket and the cylinder liner, at a point adjacent the topmost position of the top piston ring. An upper liner seal can be provided between the cylinder liner and the water jacket, above the coolant passage, and a lower liner seal can be provided between the cylinder liner and the engine frame, below the coolant passage. Coolant ports can be provided for coolant flow directly between the cylinder head and the water jacket, with seals in the coolant ports to seal the coolant, independently of the head gasket.Type: ApplicationFiled: October 25, 2004Publication date: April 27, 2006Applicant: General Electric CompanyInventors: Paul Flynn, Jeffrey Lebegue, John Dowell, Barry Record
