    摘要： A heat management system for air-cooled engines suitable to power yard care equipment or vehicles. The system may generally comprise an engine, a blower configured to blow ambient cooling air across the engine, and an exhaust system comprising an exhaust header and a muffler. The exhaust header has an inlet end which receives heated exhaust gas from the engine and an outlet end fluidly coupled to the muffler. An air control baffle is configured to redirect a portion of the cooling air from the blower towards the exhaust header and the muffler to enhance cooling the exhaust system. The system may further include an outermost protective shield exposed to equipment operators and an inner heat barrier or shield located between the muffler and protective shield. The system is designed to ameliorate both radiative and convective sources of heat transfer to maintain the protective shield at temperatures below established industry standards.

    摘要： An exhaust pipe for the exhaust tract of a combustion machine, which has an inlet opening for an air connection, is characterized by an inner pipe section which is surrounded by an outer pipe section in order to form an annular channel that is closed at one end and at the other end is open toward the inner volume of the exhaust pipe, wherein the inlet opening for the air connection opens into the outer pipe section. By means of such an exhaust pipe, advantageous mixing of air supplied via the air connection into the exhaust gas flowing within the exhaust pipe can be achieved with a simple design, which can be attributed in particular to the complete introduction of the air in combination with the flow direction that is present along the longitudinal axis of the annular channel and the exhaust pipe.

    摘要： Provided is a method of manufacturing an insulator including disposing first and second covering members, and swaging the first covering member with the second covering member. The first and second covering members each include a groove and flanges including a perforated flange. The second covering member is disposed on the first covering member such that an inner side of the groove of the second covering member faces an inner side of the groove of the first covering member; the flanges of the second covering member are individually placed on the flanges of the first covering member; and a pin retained on a base is inserted through the perforated flange of the second covering member, to thereby fix the second covering member in position. In the swaging, at least the respective perforated flanges of the first and second covering members are swaged with each other with the pin being inserted therethrough.

    摘要： Systems, methods, and apparatus are contemplated in which a tube cell that produces a dielectric barrier discharge (DBD) is individually configured to minimize the mixing of unwanted byproducts of the generated plasma with an exhaust air stream. The tube cell generates a DBD within a tube cell, such that oxidants or radicals are generated in an environment substantially separated from the exhaust stream. The generated oxidants are directed to intersect with the exhaust stream to minimize the generation of unwanted byproducts. The tube cells are further shaped and arranged in tube cell arrays to alter the flow dynamics of the exhaust stream and the oxidant or radical streams, including mixing of the streams.

    摘要： The separation efficiency of carbon dioxide is improved by making the temperature of exhaust gas further low. An exhaust gas purification apparatus for an internal combustion engine includes a first heat exchanger arranged in an exhaust passage of an internal combustion engine and configured to carry out heat exchange between outside air and exhaust gas of the internal combustion engine, a second heat exchanger arranged in the exhaust passage and configured to carry out heat exchange between a circulating heating medium and the exhaust gas, and a carbon dioxide separator arranged in the exhaust passage at the downstream side of the first heat exchanger and the second heat exchanger and configured to separate carbon dioxide from the exhaust gas.
