  "textContent": "An EGR control unit (34S), in accelerating an engine, closes an EGR valve (19) to stop EGR, in a case where an increased amount (Q) of a fuel injection amount (Q) detected by a fuel injection detection unit (31S) is larger than a preset first threshold value (Qc), a boost pressure (Pb) detected by a boost pressure detection unit (32S) is lower than a preset second threshold value (Pbc), and an engine operation state detected by an engine operation state detection unit (33S) is outside a preset high rotation and high load operation state region (Ra). As a result of this, an exhaust gas amount flowing into a turbocharger (16) can be confined within a proper range in accelerating the engine in a diesel engine (10), which avoids a rotational speed (Nt) of the turbocharger (16) from rising exceeding an allowable rotational speed (Nta) in accelerating the engine to prevent trouble of the turbocharger (16).",
