PROBLEM TO BE SOLVED: To effectively restrain dew condensation of a condensate in an end of an injector.SOLUTION: An engine includes: an injector for injecting fuel into a cylinder of the engine; and a control section for setting a required injector end temperature with the usage of an injector end temperature in turning off of an accelerator of the engine, calculating a required idle engine speed in correspondence with the required injector end temperature, and adjusting the idle engine speed of the engine to be the calculated required idle engine speed. When the calculated required idle engine speed is higher than a predetermined upper limit threshold, the control section sets the value equal to or lower than the upper limit threshold as the required idle engine speed, and performs load increase control of the engine. |
