MACKS Posted December 12, 2008 Share Posted December 12, 2008 Whats the difference in these motors,some engines are listed as Maxidyne some as Econodyne some are listed with boath names such as EM6-350 Econodyne.I know what a maxidyne is but what does econodyne mean.Also what does Thermodyne mean. I'm thinking it has something to do with the charge air cooling.Thanks for any info.

Underdog Posted December 31, 2008 Share Posted December 31, 2008 Whats the difference in these motors,some engines are listed as Maxidyne some as Econodyne some are listed with boath names such as EM6-350 Econodyne.I know what a maxidyne is but what does econodyne mean.Also what does Thermodyne mean. I'm thinking it has something to do with the charge air cooling.Thanks for any info.The Thermodyne was the first Mack diesel with direct fuel injection into the cylinders. Most diesels before it used a pre- combustion chamber in the head to mix the fuel. This was a big advance in engine power and economy.The Maxidyne, introduced in the mid sixties (along with the new R-model chassis), was the first true "low RPM" engine. Operating range 1200-2100 RPM. This again was a great improvement in power and economy at the time. Also allowed for less complicated transmissions and less shifting. Mack engineers really had this one figured out!The econodyne, as its name might imply, was an attempt at improving fuel economy. This was a lower RPM engine (1200-1800 RPM) more suited to highway travel. These may have been Mack's first 4-valve cylinder heads as well. Someone who knows better than me might offer more info on that.On modern engines, Maxidyne and Econodyne engines are set up according to what they will be used for. RPM range and torque rise is mostly defined by computer parameters. Maxidyne is set up for vocational and construction use with a wider operating range, while Econodyne is better suited for highway travel. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/7081-maxidyne-econodyne-thermodyne/#findComment-28393 Share on other sites More sharing options...

If we had known you all were so hard up, maybe Barry could have solicited for a Christmas "TOYS for SOTS" charity drive. Or at least new bottles of Monkey Grip for everyone. I prefer Gorilla Tape myself, though. Quote Link to comment https://www.bigmacktrucks.com/topic/7081-maxidyne-econodyne-thermodyne/#findComment-28551 Share on other sites More sharing options...

james j neiweem Posted January 2, 2009 Share Posted January 2, 2009 Back to the original question before the turn. Thermo means heat and dyne is a measure of energy thus thermodyne equals heat energy. originally this was probably a marketing tool. Maxidyne- maximum energy (guess). Econodyne- economy energy (guess). I believe thermodyne started with the b models. Before that the L and A models were just mack diesel if I remember correctly.

Greg Rider Posted January 4, 2009 Share Posted January 4, 2009 If it's any what-for my truck has a Magnadyne engine. Does that mean magnet power? I think all the Flathead gas jobs were called Magnadyne. I don't think the OHV gas engines were called anything special.
