Publication number: 20250058289Abstract: A mixing device for mixing a powder-liquid mixture, comprises a movable body, arranged within the housing, with a channel formed between the housing and the movable body. An actuator moves the movable body between a closed and an opened position. The movable body comprises a first body section having a first set of openings, and a second body section having a second set of openings. The housing comprises a sleeve with a covering section that covers the second set of openings when the movable body is in the closed position, for minimizing a flow of the mixture through the second set of openings, and be offset from the second set of openings when the movable body is in the open position, for allowing the mixture to flow into the channel through the second set of openings.Type: ApplicationFiled: December 15, 2022Publication date: February 20, 2025Applicant: Tetra Laval Holdings & Finance S.A.Inventors: Thomas EGGLER, Denis STEFFEN, Nora MAGONI, Sergio ZAPPELLA

Patent number: 11242787Abstract: Selective catalytic reduction systems are known and are generally included in exhaust systems of diesel engines in order to treat the exhaust gases of such engines. Such systems involve the introduction of diesel exhaust fluid (DEF) into exhaust gas flowing in an exhaust passage of an engine. When dosing DEF onto a hydrolysis catalyst in a SCR system, the DEF will under certain conditions cool the hydrolysis catalyst sufficiently to either slow down or effectively prevent ammonia release, which creates a lag or delay in the function of the hydrolysis catalyst. This limits the amount of control which can be exerted over ammonia storage in the SCR catalyst, and NOx conversion. In a first step, a set of measurement data is received from one or more sensors provided in the system.Type: GrantFiled: December 11, 2017Date of Patent: February 8, 2022Assignee: Perkins Engines Company LimitedInventors: Leo Shead, Alexis Eden, Ronald Silver, Thomas Steffen
