Increasing the engine power of a Kubota L2501 / D1703-M-DI-E4B - Part 2

This is part 2. Go here for part 1:    • Increasing the engine power of a Kubota L2...   Investigating the differences between an older direct-injection D1703 and the current direct-injection D1703 that Kubota uses in the L2501. We'll adjust the injection timing (spill timing) with some advance, and adjust the fuel rack as well. The intention here is not to throw emissions regulations into the wind, but to instead explore the differences in these motors and consider the impact of the changes for this specific motor in this specific use case. The motor in the L2501 burns diesel inefficiently and produces a lot of soot due to the lower cylinder pressures and temps. It also consumes noticeably more fuel to produce the same amount of work due to the inefficient burning. By adjusting for higher efficiency, we get less soot, and burn less fuel (don't forget PRODUCING and transporting fuel creates emissions too), but we do get slightly more NOx. What is the sum of all these parts, and what is actually better for the environment in this use case for this specific motor? From my perspective, the jury is still out on the environmental impact, but the power and responsiveness gained is black and white. Comment below with your own thoughts & opinions, but please keep the discussion and debate civil. I am not suggesting or advocating you make any of these changes to your own tractor.
