Patent number: 11035309Abstract: An internal combustion engine is provided. The internal combustion engine includes a control device, and at least one injector for liquid fuel. The injector(s) can be controlled by the control device via an actuator control signal. The injector(s) include an injector outlet opening for the liquid fuel which can be closed by a needle. A sensor is also provided for measuring a measurement variable of the injector(s). The sensor is or can be in a signal connection with the control device. An algorithm is stored in the control device, which algorithm calculates a state of the injector(s) based on input variables and an injector model, compares the state calculated via the injector model with a target state, and produces a state signal in accordance therewith. The state signal is characteristic of a change in the state of the injector(s) that occurs during intended use of the injector(s) and/or an unforeseen change in the state of the injector(s).Type: GrantFiled: November 3, 2016Date of Patent: June 15, 2021Assignee: INNIO Jenbacher GmbH & Co OGInventors: Raphael Burgmair, Medy Satria, Dino Imhof

Patent number: 10648416Abstract: An internal combustion engine is provided. The internal combustion engine includes a control device, and at least one injector for liquid fuel that includes a discharge opening for the liquid fuel. The at least one injector is connected to a collection volume by means of a line for liquid fuel. Liquid fuel can flow through the line for liquid fuel from the at least one injector to the collection volume. A control element that can be adjusted by the control device via a control signal is also provided. Via the control element, a back pressure in the line for liquid fuel can be adjusted in order to adjust an amount of liquid fuel discharged through the discharge opening of the at least one injector. Also provided is a method for operating an internal combustion engine and an injector.Type: GrantFiled: November 3, 2016Date of Patent: May 12, 2020Assignee: INNIO JENBACHER & GMBH CO OGInventors: Raphael Burgmair, Medy Satria, Dino Imhof, Stephan Laiminger

Publication number: 20180363570Abstract: An internal combustion engine including a control device, at least one combustion chamber, and at least one injector for injecting liquid fuel into the at least one combustion chamber is provided. The injector can be controlled by the control device by means of an actuator control signal. An algorithm is stored in the control device, which algorithm receives the actuator control signal and using an injector model calculates the amount of liquid fuel that is discharged via the discharge opening of the injector and compares the amount of liquid fuel calculated by means of the injector model with a desired target value of the amount of liquid fuel. Depending on the result of the comparison, the control device leaves the actuator control signal the same or corrects it.Type: ApplicationFiled: November 3, 2016Publication date: December 20, 2018Inventors: Medy SATRIA, Dino IMHOF, Raphael BURGMAIR

Publication number: 20180320618Abstract: A combustion engine with at least one injector for the injection of liquid fuel into at least one combustion chamber is provided. The injector can be regulated by means of a regulating device through an actuator triggering signal, wherein the at least one injector has an outlet opening that can be closed by means of a needle. An algorithm is contained in the regulating device, which receives as an input value at least the actuator trigger signal, and which calculates via an injector model the mass of liquid fuel transferred via the outlet opening of the injector. The regulating device compares by means of the injector model, the calculated mass with a required target value ref of the mass of liquid fuel, to correct the actuator trigger signal.Type: ApplicationFiled: November 3, 2016Publication date: November 8, 2018Inventors: Raphael BURGMAIR, Dino IMHOF, Medy SATRIA
