I can't answer that.
I am not exactly sure of this, and I feel I am getting out of my depth, but I think the M44 was developed from another engine which was only single cam. So when the M44 was put in the 318 the 't' was added to show a difference between engines.
As I say, I am unsure of the history so please, please excuse me if this is not the case.
I am not an authority on it; just stating it as I understand it. But, don't you agree that 'twin injection' makes more sense than 'touring international'? |
