PURPOSE:To properly adjust an EGR quantity against fluctuation in opening and closing of an opening/closing valve by installing an opening/closing valve located upstream from the confluence with an intake bypass path for opening and closing an intake path communicating with the intake air outlet of a pressure-wave supercharger and providing an EGR path connected to the intake air path located downstream from the opening/closing valve. CONSTITUTION:There are disposed an opening/closing valve operational state detection means 23 and a control means 40 for controlling an EGR valve 25 in such a way that the flow quantity in an EGR path 24 is changed according to the output of the detection means 23. |
