cone angle plane angle injection angle help

Not quite Toseland lol. Sorry Bash, was going to reply and forgot.

Cone angle and spray angle are the same thing, denoted in the injector part number. Plane angle is simply the angle the injector sits in the head. Or at least that's how i understand it in relation to cr injectors, as ever i expect someone will be along shortly to explain why i am wrong.

That's what I said lol,    the plane angle being the angle of the direction of spray in relation to the way the  injector is pointing.. it's denoted by the injector not by the way it sits, so for the sake of arguement if the I jector was sat perpendicular to the head, 0degrees would be coming out straight, changing the plane angle changes the direction the fuel is spraying in..  changes to the cone angle change the shape of the cone itself (how flat, or thin it is..) a 0degrees cone angle would be a single jet of fuel.. 180degrees in theory would be flat out of each side of the injector like those silly water fountain things that make a ball of water
