摘要： PROBLEM TO BE SOLVED: To provide a highly-efficient and highly-reliable exhaust treatment device provided with a catalyst in the exhaust pipe of an internal combustion engine, effectively performing control over temperature rise of the catalyst by efficiently using exhaust heat, and suppressing degradation of the catalyst or a heat medium. SOLUTION: In the exhaust treatment device having the catalyst 2 and a heating means 21 for the catalyst respectively provided in the exhaust pipe 11, a heat transfer means 41 is provided upstream of the heating means 21 and a heat transfer means 42 is provided downstream of the catalyst 2. A heat recovery passage 43 forms a circulation passage for the heat medium. According to exhaust gas temperature detected by a temperature sensor 22, an ECU 3 controls the operations of the heating means 21, heat recovery passage 43 and heat medium carrying means 44, and promotes the temperature rise of the catalyst by moving heat downstream of the catalyst 2 to an upstream side. Alternatively, heat on the upstream side is discarded to a downstream side to prevent the degradation of the catalyst 2, thereby performing efficient temperature control. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide an exhaust emission control device of an internal combustion engine which further reduces hydrocarbon to be discharged together with exhaust gas even when the temperature of catalyst is low. SOLUTION: A controller 29 supplies hydrogen as fuel when the temperature of catalyst 25 is lower than an activation temperature, and supplies gasoline as fuel when the temperature of the catalyst 25 is the activation temperature or higher. Thereby, when the activation of the catalyst 25 is low, such as at starting, hydrogen is supplied to a gasoline engine 11, and the hydrocarbon contained in the exhaust gas becomes approximately zero. When the catalyst 25 has obtained the activation temperature or higher, the hydrocarbon contained in the exhaust gas is oxidized by the catalyst 25 that has reached the activation temperature. Therefore, if gasoline is supplied, the hydrocarbon to be released together with the exhaust gas into the atmosphere is reduced. The controller 29 also increases the open degree of a throttle 23 when supplying hydrogen, thereby increasing the flow rate of air and the amount of hydrogen jet to be sucked into a combustion chamber 19. Thereby, heating value is sufficiently ensured even when hydrogen is applied to fuel. COPYRIGHT: (C)2009,JPO&INPIT
摘要翻译：要解决的问题：为了提供一种内燃机的废气排放控制装置，即使催化剂的温度低，也能够进一步减少与排气一起排放的烃。解决方案：当催化剂25的温度低于活化温度时，控制器29提供氢作为燃料，并且当催化剂25的温度为活化温度或更高时，供应汽油作为燃料。因此，当催化剂25的活化低时，例如在起动时，向汽油发动机11供给氢气，并且排出气体中所含的烃变为约零。当催化剂25获得活化温度以上时，废气中所含的烃被已达到活化温度的催化剂25氧化。因此，如果供给汽油，则与废气一起排放到大气中的烃被减少。控制器29还在提供氢时增加节气门23的开度，从而增加空气的流量和吸入燃烧室19的氢射流量。从而，即使在施加氢时也充分确保了热值燃油版权所有（C）2009，JPO＆INPIT
