Patent number: 10550808Abstract: A fuel injection system of an internal combustion engine includes: an injector having a hydraulic control chamber controlling the delivery of fuel through the injector, an actively controlled first valve system controlling the pressure relief from the control chamber, movable between: a first position in which the first valve system closes the injector by deterring the pressure from being relieved from the control chamber through the first relief circuit, and a second position in which the first valve system opens the injector by allowing the pressure to be relieved from the control chamber through the first relief circuit. A second relief circuit allows the pressure to be relieved from the control chamber through the second relief circuit. The second relief circuit includes a second valve system passively controlled by the fuel pressure and movable between two positions deterring or allowing the pressure to be relieved from the control chamber through the second relief circuit.Type: GrantFiled: December 19, 2014Date of Patent: February 4, 2020Assignee: VOLVO TRUCK CORPORATIONInventor: Guillaume Millet

Patent number: 10119508Abstract: A cover for an internal combustion engine assembly that includes a pressurized fuel accumulator feeding fuel to at least one injector is provided, the cover defining, with a cylinder head, a volume designed to receive the common rail and the injector. The cover borders a first sub-volume, designed to receive the injector, and a second sub-volume separated from the first sub-volume by a separation wall of the cover and designed to receive the common rail. The cover includes a frame to be fitted on the cylinder head and a cap removably fitted on the frame. The separation wall is designed for the passage of a fuel connection connecting the injector to the common rail.Type: GrantFiled: December 13, 2013Date of Patent: November 6, 2018Assignee: Volvo Truck CorporationInventor: Guillaume Millet

Patent number: 10107224Abstract: In a fuel system for delivering pressurized fuel both to an internal combustion engine and to an exhaust installation, the fuel system includes two separate branches for delivering fuel to the internal combustion engine and to the exhaust installation, and includes a primary fuel pump delivering fuel to both branches of the fuel supply circuit. The primary fuel pump output is controllable independently of the engine speed. The pump output may be controlled such that the pressure of fuel in the fuel supply circuit depends on whether fuel is to be delivered to the exhaust installation. The fuel system may include a hydraulically controlled shut-off valve arrangement which is forced to switch depending on the pressure in the fuel supply circuit.Type: GrantFiled: December 6, 2013Date of Patent: October 23, 2018Assignee: Volvo Truck CorporationInventors: François Giroud, Thomas Grange, Guillaume Millet

Patent number: 8803460Abstract: A device, having first and second motor units, for generating a torque on an output member in response to a torque setpoint. The first motor unit includes at least one motor of a first power, or small motor, having a shaft to which the output member is connected. The second motor unit includes at least one motor of a second power higher than the first power, or large motor, having a shaft rotationally connected to the output member via viscous coupler, and computer programmed, in response to a torque setpoint, to power the second motor unit so that the viscous coupler provides a viscous torque conforming to the torque setpoint. Further, in parallel with this, the first motor unit is powered so that it produces the additional torque between the torque setpoint and the viscous torque until the viscous torque reaches the value of the torque setpoint.Type: GrantFiled: March 9, 2010Date of Patent: August 12, 2014Assignees: Universite Pierre et Marie Curie (Paris 6), Centre National de la Recherche ScientifiqueInventors: Guillaume Millet, Vincent Hayward, Dogan Sinan Haliyo, Stéphane Regnier

Patent number: 8286613Abstract: A nozzle assembly includes a first needle and a second needle controlling respectively fuel flow towards a first series of outlets and a second series of outlets. It includes a passive control valve adapted to select, on the basis of the fuel feeding pressure, the needle to be activated for fuel delivery to the combustion chamber of an internal combustion engine. An injector with such an assembly is economic and efficient to spray fuel with two different patterns.Type: GrantFiled: July 4, 2006Date of Patent: October 16, 2012Assignee: Renault TrucksInventors: Guillaume Millet, Nicolas Dronniou
