PROBLEM TO BE SOLVED: To hold good combustibility by suppressing sticking and depositing of carbon in an injection port of a fuel injection nozzle, even in the case of lasting of low load operation of idle operation or the like performing EGR further with a small fuel injection amount. SOLUTION: In a Diesel engine provided with an exhaust gas recirculating device, exhaust gas recirculation control device 51 so as to perform recirculation of exhaust gas at least in an engine low load region and a fuel injection amount control device 52, correction means 53 is provided, which performs up loading increase correction further increasing an increase of fuel injection amount when an external load is operated in the engine low load region by a prescribed amount temporarily more than an amount matched with a target torque increase component. |
