I can't really visualize much and grasp a concept based on a verbal/written explanation when it comes to anything. But if I can see pictures and illustrations of how something works I usually don't have much trouble learning and understanding how it works. Direct injection is fairly simple mechanically speaking, but it is still pretty cool to see pics. I don't remember much in the way of emissions related stuff when I did my training on GM's direct injection stuff so I wouldn't recall any strategies like what you mentioned but it makes sense. All that I really paid attention to and committed to memory was information relating to driveability and mechanical failure diagnosis and repair.
