Abstract
A diesel engine comprises a high-pressure pump () driven by an engine (E) to supply fuel in a fuel tank () to a common rail (), an electric priming pump () provided in a fuel passage () extending from the fuel tank () to the high-pressure pump (), and a control device () to control the electric priming pump (). The control device () drives the electric priming pump () when the engine is started, if a state that the engine rotating speed (Ne) is higher than a predetermined first rotating speed (N) and the common rail pressure (Cp) is lower than a predetermined first pressure (C) continues for a period being equal to or more than a predetermined first period (T). The burden on the operator is mitigated since necessity for the priming operation can be automatically judged.
