Abstract: A multiple stage separation vortex flow air filter includes an air filter housing (AFH) having a central axis; a cylindrical helical plate located within the AFH proximate an upper shell bottom of the AFH; an air inlet eccentrically connected to the AFH to cause air flowing through the air inlet to create a vortex around the cylindrical helical plate; an perforated conical element in which the air flows through, the perforated conical element within the cylindrical helical plate around the central axis; an oblong conical casing that forms a conical passage and located along the central axis and partially within the perforated conical element, wherein air enters the conical passage through a whirling ring; and an air filter element within the oblong conical casing, wherein air flows through the air filter element and enters into an engine through an outlet pipe.

Abstract: An internal combustion engine (ICE) system, comprising an ICE; an exhaust conduit for transporting exhaust gases from the ICE to an exhaust outlet; an exhaust aftertreatment system (EATS) disposed in the exhaust conduit downstream the ICE; a flex bellow disposed in-between the ICE and the EATS; and a heater arrangement, the heater arrangement being arranged within the flex bellow and further provided in the form of a coil having one or more heating regions and one or more portions configured to induce turbulent flow of the exhaust gases. The present disclosure furthermore relates to a vehicle comprising the ICE system.

Abstract: A mudflap for a truck or a trailer, the mudflap comprising a frame, attached to a support in the vehicle, a front side being oriented toward the wheel, and a rear side oriented away from the wheel, the frame having a left upright, a right upright, a top cross member, a bottom cross member, a plurality of louvers, each louver having ends fixedly attached to the left and right uprights, each louver comprising a first louver portion having a leading free edge and a second louver portion, the second louver portion extending from the first louver portion, the first louver portion being inclined with regard to a horizontal direction by a first angle comprised between 40° and 55°, and the second louver portion being inclined with regard to first louver portion by a second angle.

Abstract: A wheel cap, comprising: an inner side, for attaching the wheel cap to a wheel rim of a wheel; a peripheral edge, coaxial with a central axis of the wheel cap; an outer face, opposite to the inner side, wherein the outer face is delineated by the peripheral edge and comprises a peripheral portion and a central portion, centered on the central axis; and openings, connecting the peripheral portion to the inner side. The outer face is concave, so that: the central portion is recessed inwards relative to the peripheral portion along the central axis; and the peripheral portion is recessed inwards relative to the peripheral edge along the central axis.

Abstract: A brake cooling system, comprising a pressurized air source configured to supply compressed air. A flow passage extends from the pressurized air source to a vicinity of a brake assembly, and has an outlet directing the air towards the brake assembly. At least one de Laval nozzle is provided in the flow passage to increase speed and reduce temperature of air passed through the de Laval nozzle. A valve controls fluid communication between the air source and the de Laval nozzle. When the valve is closed, air is prevented from reaching the de Laval nozzle. When the valve is open, air is allowed to pass through the de Laval nozzle. A temperature sensor senses the temperature of a brake assembly. If the temperature is above a predefined limit, the valve becomes opened, and air is passed through one or series of de Laval nozzle and to the brake assembly.
