  • Patent number: 9689365
    Abstract: An internal combustion engine includes a cylinder for combusting a mixture of fuel and air therein, and a starting air system configured to provide pressurized starting air to the cylinder and to monitor operability of the starting air system. The starting air system may include a pressurized starting air source, a starting air manifold, a starting air venting valve, and a sensing device. The pressurized starting air source is configured to store pressurized starting air. The starting air manifold is fluidly connected to the pressurized starting air source. The starting air venting valve is fluidly connected to the starting air manifold and configured to vent the starting air system. The sensing device is configured to detect a parameter that measures a condition within the starting air system.

  • Patent number: 9624873
    Abstract: A method is provided for detecting a leakage in a fuel supply system of an internal combustion engine. The fuel supply system includes a fuel line system with fuel line sections and a pressure monitoring system with monitoring segments, a set of valves, and a pressure sensor. The method includes detecting a leakage between the fuel line sections and the pressure monitoring system when the set of valves are opened to fluidly connect the monitoring segments. The method also includes performing at least two pressure measurements for at least two selected sets of neighboring monitoring segments for providing pressure behavior information for the selected sets of neighboring monitoring segments. The method further includes comparing the pressure behavior information of the selected sets of neighboring monitoring segments, and identifying a leaking monitoring segment based on the comparison.

  • Patent number: 9617950
    Abstract: A cylinder head for an internal combustion engine is configured to be operated with fuel, such as gaseous or liquid fuel, to provide a more complete combustion of the fuel/air mixture. The cylinder head has at least one fuel guiding section, which includes a fuel inlet valve casing for accommodating a fuel inlet valve configured to control a fuel flow rate, a fuel/air mixing chamber for mixing the fuel with air, and a fuel guiding portion connecting the fuel inlet valve casing to the fuel/air mixture chamber. The fuel guiding portion is integrally formed with the cylinder head and defines at least a first fuel feeding passage and at least a second fuel feeding passage. The first fuel feeding passage and the second fuel feeding passage extend from the fuel inlet valve casing to the fuel/air mixing chamber.

  • Patent number: 9441596
    Abstract: A valve for a fuel supply of an internal combustion engine is disclosed. The valve may have a valve housing that defines a channel in fluid communication with an inert gas supply line at a first end of the valve housing. The valve housing may also have a first flange disposed at a second end distal to the first end. The valve may have a valve body that selectively allow the channel of the valve housing to communicate with an inner bore of a double-walled connecting element of the fuel supply system. The valve housing may also have a second flange disposed adjacent to the first flange. The first flange and the second flange define a detection gap therebetween. The second flange may have a passage in fluid communication with a detection space of the double-walled connecting element and the detection gap.

  • Publication number: 20150285421
    Abstract: A connecting flange for a double-walled fuel supply line configured for use in a fuel supply system of an internal combustion engine is disclosed. The connecting flange may have a mounting surface configured to fixedly arrange an outer line element of the double-walled fuel supply line element around an inner line element of the double-walled fuel supply line element. A tubular hollow space may be provided between the inner line element and the outer line element. The connecting flange may have an end face opposite to the mounting surface. In addition, the connecting flange may have a central bore extending between the mounting surface and the end face. The end face may have a projection or a recess surrounding the central bore. The end face may also have a pair of circumferentially extending grooves formed in a front surface of the projection or in a bottom surface of the recess.
