Exhaust purification device with flattened pipe ends
A recently granted patent (Publication Number: US11859529B2) discloses an exhaust purification device designed for vehicles. The device comprises a casing that houses a purifier to clean the exhaust gas from the vehicle's engine. The casing features an inlet opening at one end for the exhaust gas to enter and an outlet opening at the other end for the purified gas to exit. The unique design includes pipes connected to the openings, with flattened connecting ends that extend laterally from the casing and have a shorter dimension in the longitudinal direction of the casing. These flattened ends make contact with the inner surface of the casing, ensuring efficient flow of exhaust gas through the purifier.
Furthermore, the patent details variations in the design, such as the inclusion of outer pipe portions connected to the flattened ends, with equal cross-sectional areas. The connecting ends can be shaped as ellipses, rectangles with rounded corners, or track shapes, enhancing the overall efficiency of the exhaust purification device. Additionally, the casing can accommodate a catalyst for selective catalytic reduction, further improving the purification process. The patent also specifies the orientation of the casing on the vehicle, aligning the longitudinal direction with the vehicle's width direction for optimal performance. Overall, the exhaust purification device described in the patent offers a novel and efficient solution for cleaning exhaust gas from vehicle engines, with a focus on maximizing purification effectiveness and space utilization.
