PURPOSE:To improve the travelling performance by providing EGR valves for opening/closing respective EGR path and means for performing open/close control of EGR valve with correspondence to the operating condition of respective cylinder. CONSTITUTION:EGR paths 6 are opened respectively to the intake paths 4 communicatable independently with respective cylinder 1a-1d. Plural EGR valves 7 for opening/closing respective EGR path 6 and means 13 for detecting the operating condition of respective cylinder 1a-1d are provided. While control means 15 will perform open/close control of respective EGR valve 7 with correspondence to the operating condition of each cylinder 1a-1d. Consequently, EGR for respective cylinder 1a-1d will correspond to the combusting condition of corresponding cylinder to uniform the combusting condition of said cylinders 1a-1d resulting in improvement of travelling performance. |
