Patent number: 10844755Abstract: A control valve for use in a cam timing phaser arrangement is disclosed comprising a cylindrical valve body, a rotational shuttle element coaxially located within a recess of the valve body, and a blocking pin. When using in a cam timing phaser arrangement having a first phasing chamber and a second phasing chamber, the control valve when non-actuated acts as a double check valve, preventing flow between chambers. Actuation of the blocking pin limits rotation of the rotational shuttle element and results in the control valve allowing flow in a single flow direction between phasing chambers. The allowed direction of flow can be controlled by controlling the timing of the deployment of the blocking pin. A cam timing phaser arrangement, internal combustion engine, and vehicle comprising such a control valve are also disclosed.Type: GrantFiled: May 10, 2017Date of Patent: November 24, 2020Assignee: Scania CV ABInventors: Daniel Olovsson, Mikael Eriksson

Patent number: 10837338Abstract: Methods and systems are provided for treatment of an exhaust stream, comprising nitrogen oxides. The method comprises a first oxidation of compounds comprising one or more of nitrogen, carbon and hydrogen in the exhaust stream; and a control of a first supply of a first additive to the exhaust stream to prevent an accumulation of soot exceeding a soot threshold value in a catalytic filter. This soot threshold value depends at least on operating conditions for the combustion engine, which impact a level of a flow for the exhaust stream. A first reduction of nitrogen oxides is performed using reduction characteristics of a catalytic coating in the catalytic filter and the supplied first additive. Soot particles are caught and oxidized. A control of a second supply of a second additive is performed, following which a second reduction of nitrogen oxides is performed using the first and/or the second additive in a reduction catalyst device.Type: GrantFiled: August 26, 2016Date of Patent: November 17, 2020Assignee: Scania CV ABInventor: Magnus Nilsson
