So I was thinking last night, you know how some modern trucks and cars will shut half of their cylinders when they don't need the power. I don't think this would be a tough thing to implement yourself on diesel engine. Possible uses for a switch that would let you disable a few cylinders would be using even less fuel and quieter operation at idle (if you are using your bus engine as a generator or water heater), or traveling on long flat interstates.
