  1. Interesting process, cleaning the carbon from the intake runners. I'm still amazed at the modern engines' carbon buildups, both the direct injection and non-direct. That EGR makes quite a mess, doesn't it. The emission process is supposed to make for cleaner engines. And even if down the road we use chemicals or walnuts to get rid of the carbon, isn't that somehow going back into the atmosphere. Like the emission process is being negated? I don't know, just trying to make sense. A bit like Ray's comment about EVs and the electrical generation process shifting the emission savings to being negated there. I'm rambling I guess. Just trying to understand. As far as Ray's business is concerned, and our viewing the videos, my questions don't matter really.
