摘要： A method for predicting soot build-up in an engine system when operating according to an intended drive cycle. The engine system includes an internal combustion engine and an exhaust gas aftertreatment system provided with a particulate filter. The method includes providing data representing engine operational conditions for the internal combustion engine during the intended drive cycle, wherein the data comprises values for at least engine speed and engine torque distributed over a time period representing the intended drive cycle; determining a working temperature for the exhaust gas aftertreatment system during the intended drive cycle based on the data representing the engine operational conditions; providing a reference relation between working temperature of the exhaust gas aftertreatment system and a corresponding estimated magnitude of a build-up of soot in the exhaust gas aftertreatment system; and predicting soot build-up in the engine system when operating according to the intended drive cycle by comparing the determined working temperature for the exhaust gas aftertreatment system with the reference relation.

摘要： The invention relates to a hydrofoil system for a marine vessel comprising a hull (101), the hydrofoil system comprising at least one pair of foldable hydrofoils (109, 110) which are pivoted relative to the marine vessel, wherein each hydrofoil (109, 110) is controllable by at least one actuator (930) for displacement of the at least one pair of foldable hydrofoils in a lateral direction of the marine vessel between a stowed position and a deployed position. Each foldable hydrofoil (109, 110) is hinged relative to the hull above the water line on opposite sides of the marine vessel. A first portion (111) of each hydrofoil extends adjacent the hull (101) towards the water line of the marine vessel when the hydrofoil is in the stowed position and a second portion (112) comprises a free second end extending under the hull. The second portion (112) is submerged and arranged in a lateral recess (107) behind a stepped hull portion (106) of the marine vessel when the hydrofoil is in the stowed position.
