Title:
ENGINE DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/175039
Kind Code:
A1
Abstract:
The objective is to provide a highly reliable and safe engine device wherein a pipeline, which is a section where intake air (outside air) and blow-by gas leaking from a fuel chamber converge, is not blocked by the accumulation of ice even when used in cold regions, and particularly in extremely cold regions with temperatures of −20°C or lower. Therefore, in the present invention a blow-by gas mixing coupling, which is for introducing blow-by gas flowing in a recirculation hose into an intake pipe, has a blow-by gas guide plate forming introduction spaces that expand on the upstream side and downstream side of a blow-by gas introduction opening, in the intake direction of an intake passage. The blow-by gas introduction plate blocks off the upstream end of the introduction space that expands on the upstream side of the blow-by gas introduction opening, and the downstream end of the introduction space that expands on the downstream side of the blow-by gas introduction opening opens into the intake passage.
