Yep, I get what you are saying. I tend to a 800 KW CAT gen like the one in the vid.
My point to others was that smoke does not = power. Unfortunately in order to get a mechanical injected diesel up to speed quickly, it needs to be over fueled and will smoke. Once the gen is up to speed + load stabilizes, there isn't any smoke.
With electronically controlled injectors ( not just an electronic controlled fuel rack ) and sensors I'd suspect the smoke on load application will be much less.
Others had asked about slamming a load at cold start. A true backup generator has a block heater holding the engine coolant at about 130 * F so the cold start is more of a warm start.
