Fuel-injected have a venturi?
My understanding (which seems to differ from every other post here - clarification please?) is that a fuel-injection system still has a venturi, but instead of the main jet in the middle of it, the fuel control unit is coupled to it to sense the pressure differential and meter the correct amount of fuel accordingly.
Is this not the case?
And therefoere of the 3 types of icing - impact, fuel and throttle ice, a fuel-injection system is free only from fuel ice (sometimes called vapourisation ice).
So given the 'right' conditions the venturi created by the throttle butterfly can still cause icing, however without the fuel to absorb some of that latent heat it is far less likely.
Thoughts?
