When I turn the key in my car I have ignition. When the engine is running I have combustion. When the experts and the Patent attornies (after making millions more) sort it all out, we'll have a decision. (which might have actually already have been made). All IMO
Ignition is the first step in combustion. Once something is ignited it WILL combust. In fact it is in the first step of combustion. You cannot draw a line without first making a dot !!! Translation-WE WIN !!!! $ HCMC $
