Engine device

摘要

An engine device in which a first case and a second case can be installed in a compact manner while preventing a decrease of temperature of the first case and the second case due to cooling air for an engine. The engine device is equipped with the first case for removing particulate matter in exhaust gas of the engine, and the second case for removing nitrogen oxide in the exhaust gas of the engine. The first case and the second case are disposed on the upper surface side of the engine at a position higher than an air flow path of a cooling fan of the engine. The second case is disposed at a position higher than the first case.
