Patent number: 9670828Abstract: A mixture-charged gas engine includes at least one cylinder. A combustion chamber delimited by a cylinder head, a cylinder wall, and a piston, which can be moved in the cylinder, is arranged in the at least one cylinder, and the combustion chamber is divided into a main combustion chamber and at least one pre-chamber fluidically connected to the main combustion chamber via at least one firing channel. An air-/combustion gas mixture can be supplied to the main combustion chamber via an inlet valve during an intake stroke of the piston. The mixture-charged gas engine is characterized in that a separate combustion gas supply is provided for the at least one pre-chamber.Type: GrantFiled: May 6, 2015Date of Patent: June 6, 2017Assignee: MTU Friedrichshafen GmbHInventors: Anko Ernst, Udo Sander

Patent number: 9562510Abstract: A spark plug for a stationary, gas-powered internal combustion engine, having a metallic body, an insulator mounted in a passage of the body, a center electrode passing through the insulator, a ground electrode mounted on the body that, together with the center electrode, forms a spark air gap, and a cap attached to the body. The cap shields the center and ground electrodes from the combustion chamber after the spark plug is installed in a combustion chamber of the internal combustion engine, and that, together with the body of the spark plug, forms a prechamber in which the center and ground electrodes are located. The cap has at least one opening that permits gas exchange between the prechamber and the space outside of the prechamber.Type: GrantFiled: August 21, 2014Date of Patent: February 7, 2017Assignee: FEDERAL-MOGUL IGNITION GmbHInventors: Werner Niessner, Anko Ernst

Patent number: 9172216Abstract: A pre-chamber sparkplug is suggested with a central electrode, with at least one ground electrode, which is distanced from the central electrode forming a spark gap, and with at least one transfer bore in a pre-chamber cap. The ground electrode comprises an internal circumferential area, which faces the central electrode, and an external circumferential area, which faces away from the central electrode. The internal circumferential area of the ground electrode shows a concave progression in the longitudinal direction of the pre-chamber sparkplug, subjected to a tensile force, and the external circumferential area shows a convex progression in the longitudinal direction of the pre-chamber sparkplug, subjected to a pressure.Type: GrantFiled: May 27, 2011Date of Patent: October 27, 2015Assignee: MTU Friedrichshafen GmbHInventor: Anko Ernst

Patent number: 8939129Abstract: A gas mixer for mixing a first gas and a second gas, including a gas housing, a Venturi tube, a flow body for the first gas arranged in the Venturi tube to form a mixing gap, an inflow tube connected to the Venturi tube, to an inflow opening to the Venturi tube for the second gas, and an actuating element for varying the inflow cross section of the inflow opening. The actuating element has a first and a second actuating part which restrict the inflow cross section. The first actuating part is a first gas housing part and the second actuating part is a second gas housing part. At least one of the gas housing parts forms part of the Venturi tube and/or of the inflow tube At least one of the gas housing parts can be moved with respect to another and has a rotor of a linear motor.Type: GrantFiled: May 15, 2012Date of Patent: January 27, 2015Assignee: MTU Friedrichshafen GmbHInventors: Johannes Prinz, Manolo Odermatt, Anko Ernst

Patent number: 8890396Abstract: The invention relates to a spark plug for a gas-fired internal combustion engine, and Includes a metallic body, with an insulator fastened in the body. A central electrode, leads through the insulator and includes a protruding end of a precious metal alloy. An annular ground electrode is fastened to the body and surrounds the end of the central electrode which, at the inside thereof facing the central electrode is provided with a precious metal or with a precious metal alloy. The mutually facing surfaces of the central electrode and ground electrode formed by the precious metal or the precious metal alloy are coaxially disposed cylinder surfaces. A cap is provided and attached to the body and which, after installation of the spark plug into a combustion chamber of the internal combustion engine, shields the central electrode and the ground electrode from the combustion chamber.Type: GrantFiled: December 15, 2010Date of Patent: November 18, 2014Assignee: Federal-Mogul Ignition GmbHInventors: Anko Ernst, Udo Sander, Mario Dittmann, Werner Niessner, Alexander Schenk
