    摘要： An exhaust gas purification system for internal combustion engines having at least two cylinders of which the port of each exhaust valve communicates with a port passage provided in the cylinder head, and a pair of the adjacent port passages communicate with a common port passage forming a siamese port passage therewith. A secondary air intake passage having a check valve communicates with the port passages for introducing secondary air by exhaust pulsation. In order to enhance the exhaust pulsation effect, the exhaust pipe connected to the opening of the common port passage has a constant cross section of a fixed diameter. Heat insulation is provided along the siamese port passage and a portion of the exhaust pipe for good oxidation of the unburned constituents. The total volume of the exhaust passage through the siamese port passage and the heat insulated exhaust pipe portion is equal to the displacement volume of the corresponding cylinders for introduction of a sufficient amount of the secondary air. The ignition timing is retarded to restrict the combustion temperature to under 2000.degree. C. for reducing the amount of nitrogen oxides.

    摘要： An air-pollution preventive arrangement for use with an internal combustion engine for motor vehicles, adapted to reduce the concentrations of noxious compounds such as unburned hydrocarbons and carbon-monoxides contained in the engine exhaust gases. The arrangement comprises a thermal reactor for primarily recombusting the exhaust gases and a catalytic converter for secondarily recombusting the exhaust gases passed from the thermal reactor so as to oxidize the residual unburned compounds. An air injection unit supplies additional air which is admixed, in a limited proportion, to the exhaust gases entering the thermal reactor to aid in the primary re-combustion of the exhaust gases therein. The noxious unconsumed hydrocarbons and carbon-monoxides are thus converted into innocuous compounds at efficiencies which are far higher than those attained where the thermal reactor or the catalytic converter is employed independently. Such additional air may also be admixed to the exhaust gases entering the catalytic converter which is located downstream of the thermal reactor, whereby the re-combustion efficiencies of the reactor and converter are maintained at high levels throughout varying driving conditions of the motor vehicle. The arrangement may also comprise a second catalytic converter which is adapted to reduce nitrogen oxides in the exhaust gases.

    摘要翻译： 适用于汽车内燃机的空气污染预防措施，适用于减少发动机废气中所含的有害化合物如未燃碳氢化合物和一氧化碳的浓度。 该装置包括用于主要再燃烧废气的热反应器和用于二次重新排放从热反应器通过的排气的催化转化器，以便氧化剩余的未燃烧的化合物。 空气注入单元提供额外的空气，其以有限的比例混入进入热反应器的废气以帮助其中的废气的初次再燃。 因此，有毒的未消耗的碳氢化合物和一氧化碳被转化为无害化合物，其效率远高于单独使用热反应器或催化转化器所达到的效率。 这种附加空气也可以混入进入位于热反应器下游的催化转化器的废气，由此在机动车辆的变化的驾驶条件下，反应器和转化器的再燃烧效率保持在高水平。 该装置还可以包括适于减少废气中的氮氧化物的第二催化转化器。

    摘要： In an afterburner installed in an engine exhaust system, a temperature sensor is positioned to establish when the temperature in the afterburner exceeds a predetermined value so that the engine intake system can be placed in communication with the atmosphere and the connection between the accelerator pedal and the throttle valve can be broken off. Consequently, the fuel supply to the engine is interrupted and the afterburner is cooled by the introduced air.
