Abstract

Abstract Translated from Japanese (57)【要約】 【目的】 エンジン再始動時における吸着剤の吸着効率 の低下防止を図ると共に、排気ガス温度に依存せずに最 適タイミングで吸着剤の再生を可能にしたエンジンの排 気浄化装置の提供。 【構成】 排気浄化用触媒4上流の排気通路3に設けら れ、排気ガス中の未燃ガスを吸着する吸着剤5と、この 吸着剤5の周囲に配置されたヒータ7とを備える。ヒー タ7への通電により発生する熱で吸着剤を温めることに より、吸着剤5から未燃ガスが強制的に脱離されて吸着 剤が再生され、これによってエンジン再始動時における 吸着剤の吸着効率の低下が防止される。 (57) [Abstract] [Purpose] Exhaust gas purification device for an engine that prevents the adsorption efficiency of the adsorbent when the engine is restarted and that enables regeneration of the adsorbent at optimum timing without depending on the exhaust gas temperature. Offer of. [Structure] An adsorbent 5 for adsorbing unburned gas in exhaust gas is provided in an exhaust passage 3 upstream of an exhaust purification catalyst 4, and a heater 7 arranged around the adsorbent 5. By heating the adsorbent with the heat generated by energizing the heater 7, the unburned gas is forcibly desorbed from the adsorbent 5 and the adsorbent is regenerated, whereby the adsorption efficiency of the adsorbent when the engine is restarted. Is prevented.
