摘要： An integral formed fluted tube intended, for example, for use as a sound suppression device in mufflers, exhaust ejectors, etc. is disclosed. The tube is formed of a cylindrical portion with generally circular inlets and outlets and a constricted portion between those ends and within the constriction, a plurality of bypasses therethrough. The constriction may also include a frontal portion having a generally concave surface which rises to an apex and thereafter forms a plurality of convex rear portions toward the outlet end. Other embodiments are shown in the Figures. The device may be used integrally within a muffler to obtain a venturi effect for an exhaust ejector and sound suppressor.

摘要： Trap for filtering particulates from diesel engine exhaust including filter cartridge arrangement having heat enhancement elements. In the case of exhaust gases flowing through a filter cartridge from inside to out and the cartridge having an inner tubular heater, heat enhancement elements include a heat insulator plugging the downstream end of the cartridge, a plurality of flow distribution rings which inhibit flow to the end of the cartridge thereby causing more even flow through the cartridge nearer the upstream end, and mechanism for controlling regeneration on-time as a function of vehicle system voltage and pre-energization heater temperature. In the case of a filter cartridge having flow from outside to in and having an outer heater, heat enhancement elements include a tubular, non-filtering, heat insulating sleeve about the heater and mechanism for controlling on-time as a function of vehicle system voltage and pre-energization heater temperature.

摘要： Diesel engine exhaust filter system for off-road vehicles. The system has a trap device and controlling mechanism on the vehicle. An electrical power source and a combustion air source are off-board. The controlling mechanism monitors backpressure to determine when regeneration is required. The vehicle is parked at a regeneration station for connection to the air source and power source for regeneration, which is then controlled by the controlling mechanism on-board.

摘要： The present disclosure relates to an exhaust aftertreatment device (30) having a core (18) and an outer housing (40) and a mounting layer (50) positioned between the core (18) and the outer housing (40). The core has an upstream end face (20) and a downstream end face (22). The mounting layer (50) and the housing (40) have main portions (52) that extend from the upstream end face (20) to the downstream end face (22) of the core (18). The mounting layer (50) and the housing (40) also include end portions (40a, 40b) that overlap the end faces of the core (18) to retain the core within the housing (40). The end portions (50a, 50b) of the mounting layer (50) are compressed against the end faces of the core (18) by the end portions (40a, 40b) of the housing (40).

摘要： An engine exhaust filtering system (10) filters carbon particles from exhaust gases. A length of pipe (12) leads from the engine to promote the agglomeration of carbon particles in the exhaust gases. The exhaust gases then pass through a diffuser (36) having a series of chokes (38) to promote further turbulence and agglomeration of the carbon particles. A diffuser (36) directs particles for uniform distribution over a filter cartridge (22). After passing through the filter cartridge (22), the filtered exhaust gases are then expelled into the atmosphere. The filter cartridge (22) is removable and can be reused after the particles are removed.
