A diesel engine comprising a fuel injection device ( 9 ), an EGR device ( 19 ), and a control device ( 26 ) for controlling the fuel injection device ( 9 ) and EGR device ( 19 ) so as to realize a premixed combustion in which a mixture is ignited after the end of fuel injection, the diesel engine further comprising detection unit ( 31 ) for detecting the ignition timing of the mixture, wherein when the actual ignition timing detected by the detection unit ( 31 ) shifts from the preset optimum ignition timing, the control device ( 26 ) corrects the timing of fuel injection conducted by the fuel injection device ( 9 ) and matches the actual ignition timing with the optimum ignition timing.
