PROBLEM TO BE SOLVED: To carry out rotating speed control of good response in idling operation even when an excess air ratio falls and the degree of constant volume falls in a diesel engine. SOLUTION: The degree of constant volume CVOL during idling operation is predicted from at least one of the excess air ratio, ignition timing of fuel and a compression end temperature in a cylinder (S1). Motoring load FMO during idling operation is predicted from at least one of intake pressure, the excess air ratio, water temperature and auxiliary machine load (S2). An idling injection quantity is computed from the degree of constant volume CVOL and motoring load FMOT (S3-S6). COPYRIGHT: (C)2006,JPO&NCIPI
