A device serves for filtering a fluid contaminated with particles, in particular an exhaust gas transporting particulate matter from an engine. The device is provided with an outer container and at least one filter device of a porous material. The porous material of each of the at least one filter devices has a number of folds extending in the direction of flow. Furthermore, the porous material has in its cross section a closed geometrical form with at least one inner opening.

Porous folded filter device for filtering a fluid contaminated with particles

A fuel injection system for an internal combustion engine with a reservoir for pressurised fuel and at least one fuel injector which has a solenoid activated valve to control fuel pressure therein, and including a control piston linked to the injector's valving member and defining a control space communicated with the injector's fuel, and further including a pressure regulating valve assembly with another solenoid activated valve operated independently of the injector's solenoid valve and which is located between the reservoir and the fuel injector for selectively creating different flow control configurations to regulate fuel pressure delivered to the injector. The two solenoid activated devices providing an injector control for providing flexible opening operation of the injector at more than one fuel pressure level.
