Talk:Active Fuel Management

Notes[edit]

Added a line about power consumption of 'dead weight' materials at the request of a friend. However, on verification, I'd like to see a little more added along the lines of.. While other cylinders are shut off, the pistons continue to compress and decompress gas, requiring power from the engine to move the pistons and crankshaft portions which are not used for producing power. The actual power required in compression, however is balanced by the decompressing gasses in other cylinders.

Honda uses the displacement on demand technology now

Honda's is covered at Variable Cylinder Management. --SFoskett 15:00, May 13, 2005 (UTC)

GM's press site indicated that the name "Displacement on Demand" was going to be renamed "Active Fuel Management". Evidence of this is apparent on the 2006 Chevrolet Tahoe's Vortec 5.3. So what would that mean for this article?--24.89.215.104 01:26, 8 January 2006 (UTC)[reply]

This whole article seems like a press release. I suggest a rewrite or deletion.

Agreed. This article should be combined with Honda's Variable Cylinder Management and given a non-patented neutral name for what is essentially the same technology. --NickGlasowiski (talk) 16:46, 29 April 2008 (UTC)[reply]

Hummm, after reading the "How It Works" It seems that GM has made it way more complicated than it would need be. Wouldn't it also work by stopping fuel to opposing cylinders and letting the valves work normally and incorporate and compression release on the deactivated cylinders. (This comment wasn't signed.)

No, that doesn't work. Unless you close the valves the engine simply becomes less efficient due to pumping losses. Aside from lab work, this has been tried in the field and the engine just runs like a dog. The link to the Cadillac XV12 engine is broken. The link to the XV16 engine took me to a standard Cadillac page. 80.176.88.36 (talk) 20:55, 7 October 2008 (UTC)[reply]

Mercedes??[edit]

Didn't Mercedes' S600 series have this same type of technology for a few years in the 1990s? --76.115.67.114 (talk) 19:07, 28 October 2011 (UTC)[reply]
