Abstract: A dual fuel engine system is provided. The dual fuel engine system includes a dual fuel engine. The dual fuel engine system also includes a turbocharger connected to the dual fuel engine having a turbine portion and a compressor portion. The dual fuel engine system further includes a methane reduction module positioned downstream of the turbocharger. The methane reduction module is configured to receive a flow of exhaust gas from the turbine portion of the turbocharger. The methane reduction module includes a combustor. The methane reduction module is adapted to increase a temperature of the exhaust gas flow received from the turbine portion of the turbocharger. The methane reduction module is also adapted to combust methane constituents present in the exhaust gas based on the increase in the temperature.

Abstract: A fluid level monitoring system for a container defining a chamber includes first and second flexible interdigital capacitive sensors located at first and second ends of the chamber and disposed about a longitudinal axis of the chamber. The first and second flexible interdigital capacitive sensors are configured to be immersed, at least in part, within a fluid contained in the chamber. The fluid level monitoring system further includes a controller disposed in operative communication with the first and second flexible interdigital capacitive sensors, to determine a level of the fluid in the chamber based, at least in part, on an average of measure of parameters received from the first and second flexible interdigital capacitive sensors.

Abstract: A method for quality testing a tube bundle is provided. The tube bundle includes a plurality of tubes. The method includes providing a collimated light source and a receiving screen at a first end and a second end of the tube bundle respectively. The second end of the tube bundle is distal from the first end of the tube bundle. The method further includes directing a light beam through the tube bundle, wherein the light beam enters the tube bundle at an incident light intensity. The method includes passing the light beam through each of the plurality of tubes. The method also includes measuring, on the receiving screen, a received light intensity of the light beam exiting each of the plurality of tubes. The method further includes comparing the received light intensity with the incident light intensity, and determining a quality of the tube bundle based on the comparison.

Abstract: An ultraviolet sensor arrangement detects the amount of sulfur in a fuel of an internal combustion engine by emitting an ultraviolet light field in the presence of the fuel. A detector is disposed to detect a responsive amount of fluorescent light and provide a sensing signal indicative of the amount of sulfur in the fuel. A filter (or filters) receives the sensing signal and provides a filtered sensing signal to a sensing circuit.
