摘要： A system for purifying exhaust gas from an internal combustion engine comprises a catalytic reactor housing in which a catalytic reaction bed is housed. The bed defines therein first and second groups of passages arranged in heat-exchange relationship. The first group of passages is for the exhaust gas while the second group of passages is for air to control the temperature in the bed. A thermocouple detects the temperature in the bed and emits a signal which a comparator compares with reference signals and is operative to cause a blower to be driven so that air is forced into and flows through the second group of passages in the bed to cool the same when the temperature detected is above a predetermined range to thereby prevent catalyst in the bed from being melted. An electric heater is additionally provided in an air supply tube between the blower and the reactor. When the temperature is below the lower limit of the predetermined temperature range, the comparator operates to cause the blower to be also operated and, at the same time, cause the heater to be energized so that the air supplied to the bed is heated to heat the bed to a temperature at which the catalyst is appropriately activated.
摘要翻译：用于净化内燃机废气的系统包括其中容纳有催化反应床的催化反应器壳体。床在其中限定了以热交换关系布置的第一组和第二组通道。第一组通道用于废气，而第二组通道用于空气来控制床中的温度。热电偶检测床中的温度并发出比较器与参考信号比较的信号，并且可操作地使鼓风机被驱动，使得空气被迫进入并流过床中的第二组通道以将其冷却当检测到的温度高于预定范围时，从而防止床中的催化剂熔化。在鼓风机和反应器之间的空气供应管中另外设置电加热器。当温度低于预定温度范围的下限时，比较器操作以使鼓风机也被操作，并且同时使得加热器被通电，使得供应到床的空气被加热到热床到达催化剂适当活化的温度。

摘要： An electrical oxygen (O2) concentration sensor (1) has a specially designed seal at the end of the housing (10) to hold the wires (31,32,41) leading to the sensor element (3). The seal consists of an elastic insulation material (2), fixed inside a protective covering (11,12), within which holes (20) are bored to carry the leads. A radial rib (21) in the elastic insulant round each wire helps to hold the leads in place. The whole seal is held firmly by its covering, providing a secure and dense protective barrier and allowing accurate testing over a longer period.
