Abstract: Method for identifying slow transient variations and/or local spatial variations in vehicle related fluid dynamic conditions of a physical property in a set of data points. The method includes obtaining a first set of data points, calculating a temporal filtered value of the representation of the physical property for at least a portion of the first set of data points distributed over the total time period, combining at least a portion of the calculated temporal filtered values to obtain a second set of data points, and analysing in time sequence the second set of data points over at least a portion of the total time period.

Abstract: A passive shutter mechanism (10; 20) for a cooling pack (2) in a vehicle (1) adapted to selectively close at least part of an airflow path into the cooling pack (2), wherein the shutter mechanism comprises at least one blocking member (11; 21) adapted to be displaced between an open position, wherein air may flow into the cooling pack (2), and a closed position, wherein air is prevented from flowing into at least part of the cooling pack (2), depending on the movement of the vehicle (1). A vehicle (1) comprising such a passive shutter mechanism, as well as a method of operating such a passive shutter mechanism is also disclosed.

Abstract: A fuel ejector assembly for a vehicle. A second fluid passage extends into a first fluid passage so that a nozzle opening is arranged inside the first fluid passage facing an outlet flow port such that a first flow of fuel in the first fluid passage flows around the nozzle opening. A flow shape unit is disposed within the first fluid passage in connection to the nozzle opening.

Abstract: A purge ejector assembly for a vehicle. A second fluid passage extends into a first fluid passage so that a nozzle opening is arranged inside the first fluid passage facing an air channel flow port such that a flow of air in the first fluid passage flows around the nozzle opening, and wherein a flow shape unit is disposed within the first fluid passage in connection to the nozzle opening.

Abstract: A method, system and computer program performed by a system and a system for wireless communication between electronic control units (ECU's) in a communications network, the electronic control units being adapted for association with at least one vehicle, the method including determining a first electronic control unit, determining a second electronic control unit, determining a first network delay between the first electronic control unit and the second electronic control unit, calculating a first offset time for the first network delay, detecting time from a time source, detecting pulse from a pulse source, transmitting a message from the first electronic control unit to the second electronic control unit, coordinated processing of the message in the first electronic control unit and the second electronic control unit based on the first offset time, the time and the pulse.

Abstract: An arrangement (10) in a wheel well (2) of a vehicle (1), comprising at least one passage (11) providing fluid communication between an engine compartment (3) and the wheel well to permit airflow there through, wherein the passage is non-straight in order to prevent ingress of water into the engine compartment. Also disclosed is a vehicle comprising such an arrangement.

Abstract: The invention relates to a fabric filter system, having a first fabric filtering device in the form of elongated tubular fabric bag; a first gas tank for providing compressed gas; a first pulsing gas duct fluidly connected between the first fabric filtering device and the first gas tank through a first pulsing valve for cleaning the first fabric filtering device. The fabric filter system further includes a second gas tank for providing compressed gas. The second gas tank is fluidly connected with the first gas tank through a control valve. The first pulsing valve is opened to introduce the compressed gas into the first filtering device for cleaning when the control valve remains open. The control valve is closed after a predetermined time. A method for cleaning the fabric filter system is disclosed.

Abstract: The fabric filter includes a first chamber with an inlet, a second chamber with an outlet, filter bags housed in the first chamber and having mouths that open in the second chamber and defining at least a bag nest, manifolds with nozzles facing the mouths and housed in the second chamber, a flow direction along which during operation a dirty gas to be treated in the fabric filter enters the bags nest. Angles between the manifolds and the flow gas direction are bigger than 45 degree.
