Abstract
To provide an engine device with high reliability and high safety in which a pipe conduit in a portion where a blow-by gas having leaked from a combustion chamber is merged with intake air (outdoor air) is not blocked with ice coating even in use in a cold region, especially an arctic region at −20° C. or less, a blow-by gas mixed joint configured to introduce a blow-by gas flowing in a returning hose to an intake pipe includes a blow-by gas guide plate that defines introduction space expanding upstream and downstream of a blow-by gas inlet in an intake direction of an intake passage. The blow-by gas guide plate closes an upstream end of a part of the introduction space expanding upstream of a blow-by gas inlet and opens a downstream end of a part of the introduction space expanding downward of the blow-by gas inlet in the intake passage.
