Abstract: An oil cooled cylinder liner, a method for cooling the same, and an opposed piston engine using the oil cooled cylinder liner are described. The cylinder liner includes a liner wall that has an inner face adjacent a piston bore and an outer face including an oil gallery surface. A plurality of grooves are disposed along the oil gallery surface. The grooves run parallel to each other and are spaced apart by bridging portions of the liner wall. At least some of the grooves have at least one fin disposed therein that runs parallel with the grooves. The grooves in combination with the fins increase surface area of the oil gallery to improve heat transfer from the liner wall to oil disposed along the oil gallery surface.

Abstract: A system and method for determining the quality of natural gas is provided. The system includes a fuel line for communicating natural gas to an engine. An infrared light source is disposed along the fuel line and is configured to emit a beam of infrared light into the fuel line having a wavelength of 6 to 10 micrometers. An infrared light detector detects a transmission value of the natural gas as the beam of infrared light passes through the fuel line. A natural gas quality module receives the transmission value from the infrared light detector and determines a quality value of the natural gas based on an amount of infrared light absorbed by methane in the natural gas. An engine control module, including a feed-forward control loop, receives the quality value from the natural gas quality module and alters an operating parameter of the engine in response thereto.

Abstract: A power plant is provided and may include an engine configured to receive charge air and produce exhaust. A first turbo machine may be driven by the exhaust and may drive a compressor that receives air and produces the charge air. A second turbo machine may receive the exhaust and may rotationally drive a pump in response thereto. The pump may receive an EGR from the exhaust and may introduce the pumped EGR to the charge air.
