WHEN AN EGR CONTROL VALVE (21) IS FIXED AND A VALVE OPENING DEGREE EGRVO OF THE EGR CONTROL VALVE IS GREATER THAN A VALVE-OPENING THRESHOLD VALUE EGRVOTH, A LIMIT VALUE QLIM OF THE INTAKE AIR AMOUNT IS SET TO A PRESCRIBED AMOUNT QLIM1. CONVERSELY WHEN THE EGR CONTROL VALVE IS FIXED AND THE VALVE OPENING DEGREE EGRVO OF THE EGR CONTROL VALVE IS LESS THAN OR EQUAL TO THE VALVE-OPENING THRESHOLD VALUE EGRVOTH, THE LIMIT VALUE QLIM OF THE INTAKE AIR AMOUNT IS SET TO A PRESCRIBED AMOUNT QLIM2. |
