Title: Waste heat recovery system including a mechanism for collection, detection and removal of non-condensable gas

Patent ·
OSTI ID:1364593
;

The disclosure describes a non-condensable gas collection, detection, and removal system for a WHR system that helps to maintain cycle efficiency of the WHR system across the life of an engine system associated with the WHR system. A storage volume is configured to collect non-condensable gas received from the working fluid circuit, and a release valve is configured to selectively release non-condensable gas contained within the storage volume.
