The system comprises an exhaust gas recirculation manifold arranged to distribute recirculated exhaust gas in an intake air stream to be introduced into the combustion engine; wherein the manifold has an exhaust gas recirculation inlet and an intake air inlet as well as at least one outlet leading to the multiple cylinders of the engine. The system also comprises a first distribution pipe, which has a first pattern of flow distribution perforations for distributing the recirculated exhaust gas into the manifold. The system further includes a second distribution pipe with a second pattern of flow distribution perforations for distributing the recirculated exhaust gas into the manifold, and at least one of the first and second distribution pipes being rotatable with respect to the other.


A system and method for estimating traffic intensity uses data from a subset (SV_(1-n)) of connected vehicles equipped with positioning systems (1) and active safety sensor systems (2a, 2b) capable of determining vehicles travelling in an opposite direction within a road network (9). It is determined whenever a connected vehicle meets another vehicle, and a position of the connected vehicle and data regarding met vehicles is reported to a back end system (6) which also provide instructions. The positions and directions of travel of the connected vehicles are kept track of and it is also determined whenever two connected vehicles within the subset (SV_(1-n)) meet one another. The number of vehicles a connected vehicle meets is counted and the total number of vehicles that passes a position within the road network (9) in a given direction is estimated based on the positions and directions of travel of the connected vehicles and the associated vehicle counts.

The present invention refers to exemplary embodiments of a pressure control device, a displacement control arrangement and a pumping arrangement, wherein the displacement control arrangement is part of the pumping arrangement and comprises a control ring, a rear face of a pump unit and the pressure control device. The rear face of the pump unit may belong to any type of pump unit comprising pressure chambers. The pressure control device is provided with a plurality of rotation symmetrically arranged through holes. Respective through hole is defined by a circumferential inner surface, wherein the circumferential inner surface of the through hole is provided with at least one protrusion extending into the through hole such that a midsection of the through hole has a smaller extension in an intended rotational direction than an outer section and an inner section of the through hole. The pressure control device is fixedly arranged to an axial surface of the rear face of a pump unit and the second axial surface of the pressure control device is facing an axial surface of the control ring. The rear face of a pump unit and the pressure control device are rotational symmetrically arranged about a first rotational axis and the control ring, which is provided with at least a first and a second opening formed as semi-circular arcs, and which are separated by a first and a second land, is rotational symmetrically arranged about a second rotational axis, wherein the second rotational axis is radially offset by a distance E in relation to the first rotational axis, and is arranged in parallel to the first rotational axis. Due to the radial offset between the first and second rotational axis, and due to the configuration of the through holes, by changing the displacement of the displacement pump the angular distance, thus the period pf time, the through holes are completely blocked by the first and second lands may be varied.

The present disclosure relates to a safety catch release mechanism (19) for release of a safety catch in a hood lock of (7) a vehicle (1). The safety catch release mechanism comprises a handle member (23), which is adapted for manual operation, and a safety catch operating member (25), which is adapted to be connected to the hood lock in order to release the safety catch (17). The handle member is displaceable from a first position, corresponding to a closed hood, to a second position, in which the handle member is manually operable. The handle member is further displaceable from the second position to a third position corresponding to the hood lock being released. The displacement of the handle member from the first position to the second position is independent of the safety catch operating member, but during displacement from the second position to the third position, the handle member concurrently displaces the safety catch operating member from a first position, corresponding to the hood lock being retained by the safety catch, to a second position, corresponding to releasing the safety catch. The disclosure further relates to a grill (11) and a vehicle (1) comprising such a safety catch release mechanism and to a method of opening a hood (3) of a vehicle.
