ODD/even firing engines!

can anyone explain this to me?
i seem to be having trouble finding anything on the internet!
is the vg30 odd firing or even?

Most engine including the VG30 is even fire, what that means is the cylinders all fire at even degree intervals apart from one another. For example out of the 720 degrees each cylinder fires once and 120 degrees apart making it an even fire engine. An Odd Fire V6s fires at intervals something like 132, 108, 132, 108, 132, 108 in a full 720 cycle of the engine.
