Replying to: coolrunning (Jun 11, 2008 12:41 am) "If it periodically unloads 50% of the cylinders, why isn't it 50% better fuel efficiency?"   Look at it this way, if the engine was being called upon to deliver say 32 hp to sustain say 65 mph (just an educated/non-scientific guess that probably isn't far off the mark), then each cylinder needs to be fed enough gas and air to develop 4 hp. Since the engine is designed to put out 42.5 hp per cylinder at WOT, running the engine at less than a tenth of that power is not terribly efficient.   When the ECU shuts off half of the cylinders, the power requirement of 32 hp to sustain the speed doesn't drop one bit, and as such, each of the 4 remaining cylinders must now be called upon to produce 8 hp. Even though the 8 hp isn't likely to be as efficient at burning fuel as whatever the engine's most efficient point is, it's still more efficient than asking 8 cylinders to produce 4 hp each, hence the 11% bump in fuel economy.   Make sense?   Best Regards, Shipo
