Icing in Piston Engine Intake Ducts
This is not a query about carburettor icing. The mechanism for this is well documented. However, most references say that icing in the intake duct cannot, or does not, occur with fuel injection sysytems
However, there is some potential for adiabatic cooling in the intake when the air valve is closed. Question. Is there any evidence at all out there of icing in the intake duct or manifold of fuel injected engines?
