Publication number: 20130245872Abstract: A hybrid powertrain includes a combustion engine, an electric machine arrangement, a gearbox operable to receive motive power from at least one of the combustion engine and the electric machine arrangement for providing motive power to a load of the powertrain. The powertrain is configurable in operation so that its combustion engine is switchable between an inactive state and an active state. The combustion engine is cranked to switch it from its inactive state to its active state. Application of cranking torque to the combustion engine is controlled in operation to substantially temporally coincide with a gear change in the gearbox.Type: ApplicationFiled: March 20, 2013Publication date: September 19, 2013Applicant: VOLVO TECHNOLOGY CORP.Inventors: Lars Lars CARLHAMMAR, Svante KARLSSON, Helene PANAGOPOULOS

Publication number: 20120103805Abstract: A diagnosis method and a gas sensor that is adapted to perform the diagnosis method are described for detecting a damage of a gas sensor causing a malfunction, particularly a crack, wherein the gas sensor has at least two chambers with one chamber comprising a reference gas. The method includes pumping out gas of one of the chambers, measuring a value of a variable being proportional to the concentration of the gas as a function of time, comparing the measured variable value and/or the measured time to a predetermined threshold, detecting a damage of the sensor if the measured variable value and/or the measured time is outside the interval of normal mode of operation defined by the corresponding predetermined threshold.Type: ApplicationFiled: December 29, 2011Publication date: May 3, 2012Applicant: Volvo Technology Corp.Inventors: Charlotte Holmen, Henrik Svenningstorp

Patent number: 7921647Abstract: An internal combustion engine exhaust gas system includes an EGR arrangement adapted to lead a first flow of exhaust gas, the EGR flow, from an outlet side of the engine to an inlet side of the engine, an exhaust gas conduit adapted to lead away a second flow of exhaust gas, the exhaust flow, from the outlet side of the engine, and an energy recovering unit, such as a turbo, associated with the exhaust gas conduit. The unit is adapted to recover exhaust gas energy from the exhaust flow. The system includes a heat exchanger adapted to allow heat exchange between at least a part of the EGR flow and at least a part of the exhaust flow, the heat exchanger being associated with the exhaust gas conduit at a position downstream the energy recovering unit.Type: GrantFiled: June 29, 2005Date of Patent: April 12, 2011Assignee: Volvo Technology CorpInventors: Daniel Grunditz, Mikael Larsson, Arne Andersson, Lennart Cider, Edward Jobson, Martin Lunden, Peter Josza
