Abstract: Device for the abatement of pollutants of an internal combustion engine comprising an external casing in which a DOC and a bypass duct of the DOC is housed to define a bifurcation for the exhaust gases passing through the device, so that a first flow is intended to cross the DOC and a second flow is intended to bypass the DOC, an injector of urea-based reducing agent arranged at or at a point immediately downstream of the bifurcation and an electric heater arranged annularly with respect to the bypass duct and configured to heat the bypass duct and to be passed by the first exhaust gas flow.

Abstract: An exhaust system for an internal combustion engine, which is provided with a feeding pipe of fresh air to an intake manifold and with a turbocharger arranged along the feeding pipe; the exhaust system displays: an emission pipe for releasing the exhaust gases produced by the internal combustion engine into the atmosphere; at least one gas treatment device, which is arranged along the emission pipe and consists of an oxidizing catalyzer and an anti-particulate filter; and a recirculation circuit, which displays a recirculation pipe which is regulated by a recirculation valve and connects the emission pipe downstream of the treatment device to the intake pipe upstream of a compressor of the turbocharger to introduce into the intake pipe a certain amount of exhaust gases present in the emission pipe; along the recirculation pipe a filter consisting of a metallic mesh arranged to close the recirculation pipe is arranged.

Abstract: The cartridge has two compartments normally for containing two substances of the mixture, which are separated by a preferential break member; one of the two compartments contains a liquid solvent, and is fitted with a bellows having an intake valve and for producing a pumping action by varying the volume of the bellows by exerting pressure on the bellows. The bellows first causes breakage of the member to mix the two substances, and then produces flow of the mixture to accelerate its reaction. The cartridge is insertable inside a cavity of a support for heating or cooling in predetermined conditions.

Abstract: A miniaturized sensor device comprises at least one pair of active projecting elements or cantilevers, which are set parallel to one another and at a micrometric or sub-micrometric distance apart and are designed to be submerged at least partially in a fluid. Each pair comprises a first cantilever, equipped with actuator means, and a second cantilever, equipped with sensor means. The actuator means can cause a movement of the first cantilever, whilst the sensor means can detect a movement of the second cantilever, induced by the movement of the first cantilever, for generating accordingly a measurable signal, which represents the lubricating capacity of the fluid.

Abstract: An evaluation method in which a capacitive sensor is placed in a region of a container, into which a granular material is fed so as to contact the sensor, and the variation in the impedance of the sensor caused by feeding in the material is evaluated. The method is particularly useful for evaluating the compactness of sand in a formwork for making metal castings. The evaluation system includes a sensor defined by plates sensitive to the variation in the dielectric; and a conditioning and control circuit for indicating the variation in the capacitance of the plates, or more generally the total impedance of the system, when the granular material is fed into the container. In one embodiment, the plates of the sensor are defined by two combs made of conducting material, having two numbers of interlacing segments, and located on a rigid or flexible support.
