<p>The present invention addresses the problem of providing a diesel engine with which the generation of black smoke in upland areas can be prevented. This diesel engine (100) is equipped with: an EGR device (30) which, by means of an EGR valve (32), opens and closes an EGR passage (31) connecting an exhaust passage (20) and an intake passage (10), thereby recirculating a portion of the exhaust gas from the exhaust passage (20) to the intake passage (10) via the EGR passage (31); and an ECU (50) that controls the recirculation of the exhaust gas by the EGR device. In addition, this diesel engine is equipped with an atmospheric pressure sensor (60) that detects the atmospheric pressure, and when the atmospheric pressure detected by the atmospheric pressure sensor (60) after the completion of startup is equal to or less than a prescribed pressure, the ECU (50) stops the recirculation of the exhaust gas by the EGR device (30).</p> |
