Abstract
An engine system including an air intake duct positioned upstream of an engine cylinder may include an ice ingestion feature for retaining condensation. An ice ingestion feature may include indents formed in the bottom of an air intake duct wall. As such, the ice ingestion feature may include compartments and/or grooves of varying depths, widths, and/or angles such that the ice retention rate may be based on the surface area of the compartment or grooves.
