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 heat exchanger includes a case with at least a case inlet and at least a case outlet. A separation structure located within the case defines a first section and a second section. A bundle of tubes or other means for transferring heat is housed within the first section. The first section has the case inlet and the second section has the case outlet and a liquid drainage. The heat exchanger also has channels having longitudinal axes directed towards a side of the case.
