Abstract
PURPOSE: To prevent an after burning by providing a heat accumulator taking an oxidizing reaction to unburnt components, at an upstream point of a specific one for supplying a secondary air, of exhaust passages running from respective cylinders so as to take the above said reaction to the unburnt components.
CONSTITUTION: Exhaust gas passages 10W13 respectively connected to cylinders 2W5 of an engine 1 are gathered and connected to an exhaust gas purifier 15. A secondary air supply path 16 is connected to the specific exhaust gas passage 10 and a heat accumulator 19 taking an oxidizing reaction to unburnt components is provided at an upstream point of the passage 10. If a secondary air is fed reversely to increase unburnt components in exhaust gas carried from he cylinder 2, the unburnt components are oxidized in reaction to the heat accumulator 19 so that its amount is reduced. An air fuel ratio is therefore leaned to range where an after burning does not occur. The after burning caused by a supply of secondary air can be surely prevented.
