I think this may be what you are describing. [zen_tom, Feb 24 2011]
Wikipedia: Variable Cylinder Management
Honda's version of the technology: "It uses the i-VTEC system to disable one bank of cylinders during specific driving conditions (for example, highway driving) to save fuel. The 2008 Accord takes this a step further allowing the engine to go from 6 cylinders, down to 4, and further down to 3 as the computer sees fit. Honda's VCM uses overhead cams as opposed to DaimlerChrysler's Multi-Displacement System and General Motors' Active Fuel Management pushrod systems." [zen_tom, Feb 24 2011]
||I'm pretty sure there's been talk here before about running differing numbers of cylinders depending on load, and almost sure that there are actually engines already out there that do this.
||As [tom]'s link shows, the principle of not using all the cylinders all the time is widely known to exist and so this is [marked-for-deletion]. My car has an i-VTEC engine and I wish there was something on the dashboard display which told me how many cylinders it was using - it would just be nice to know, that's all.
