However it also add that power over the whole engine curve. But a turbo adds power at, usually calculated and designed, a specific rpm. <br /><br />And with a diesel you can have the Tubos create a lot of power at very low rpms. High speed, as in 5k rpm, diesels don't really exist until like the 60's 70's due to how a diesel works.<br /><br />What was the most Powerful Tank Diesel used by America during WW2?<br />http://answers.yahoo.com/question/index?qid=20090724210728AAK1XeP<br /><br />Also with tank engines in the Panther through Tiger II they were limited to 3k rpm. I have seen reports of over revs to 3200 which meant that the Germans started putting a governor on the engines to preserve engine life. <br /><br />A diesel has very low horsepower without any supercharging for its displacement and adding a supercharger only adds to the mechanical problems that could occur not to mention cost to build. A turbo also adds cost to maintenance on top of, like a roots type, the additional heat and stresses on engines (Maybach HL230) that already had almost every corner cut on it to ease production stress and still give power. <br /><br />Plus one source of fuel kept things simple. Which is why the USA used gasoline for the most part. <br /><br /><br />The M10 tank destroyer did use the: <br />General Motors 6046 Twin Diesel 6-71 375 hp (276 kW). <br />Power/weight, 12.5 hp/ton. <br />Weight 29.6 metric tons (65,000 lb)<br /><br />Considering that even the Panther:<br />Maybach HL230 P30 700 PS (690 hp, 515 kW)<br />Power/weight 15.39 PS/tonne (13.77 hp/ton)<br />Weight 44.8 tonnes (44.1 long tons; 49.4 short tons)<br /><br />And that you need a lot more engine to get an equal power from a diesel compared to a gasoline... Its no contest. Plus gasoline engine does have the advantage of higher rpms, which was needed on the German tanks due to the engines being directly connected to the turrets. Plus the added advantage of one engine design for over 7800 tanks is an ease on manufacturing. Diesel engines also need more metal in them due to the extra forces from compression ignition.CaptianNemohttps://www.blogger.com/profile/18276525826633146549noreply@blogger.comtag:blogger.com,1999:blog-803236411311363895.post-52271220848360436182013-06-06T16:44:41.093+02:002013-06-06T16:44:41.093+02:00The Leo I doesn't have a native diesel engine ...The Leo I doesn't have a native diesel engine though. It did have at the beginning but multifuel was planned and eventually equipped later to all of them. But I don't want to be pedantic. Basically you are right! Twin supercharged even.<br /><br />And thanks to Nemo for the hints.<br />It is not so much that I had any questions about it. I just wanted to be sure that this isn't a mistake. I have never heard of supercharged diesel engines before and I could think of some good reasons for not supercharging a diesel engine.<br /><br />But all right, it is correct.

Just for engineering and design. Another 7 gigs on novels. =)CaptianNemohttps://www.blogger.com/profile/18276525826633146549noreply@blogger.comtag:blogger.com,1999:blog-803236411311363895.post-20297953331179357552013-06-06T04:08:41.778+02:002013-06-06T04:08:41.778+02:00Thank you captain. :-DThank you captain. :-DExxec71https://www.blogger.com/profile/05100162498627493683noreply@blogger.comtag:blogger.com,1999:blog-803236411311363895.post-29046435244897100582013-06-06T03:03:39.770+02:002013-06-06T03:03:39.770+02:00Diesels have been roots-type supercharged before.
...Diesels have been roots-type supercharged before.<br /><br />SO a Turbo-charged engine would give more power...<br /><br />HOWEVER. In my own research into aircraft engines supercharged can mean turbo-charged. And it can get insanely confusing as to which type of supercharger they are talking about even with the primary source. Only a careful reading of the source can tell us, in context, which supercharger it is.<br /><br />Turbo is usually mentioned as a Turbo-charger. And what we think of as a normal supercharger is a Roots type supercharger.<br /><br />However a 3ed type exists. a Turbo-supercharger. Which uses both types to allow an engine with a turbo charger to be efficient due to the bend in the turbo piping. As best I recall, the air passes through the turbo through the cooler and into a supercharger then engine then back to the turbo.<br />Example: http://img300.imageshack.us/img300/5610/typebcontrolnh6.jpg<br /><br />More Reading:<br />http://rwebs.net/avhistory/opsman/geturbo/geturbo.htm<br />http://www.enginehistory.org/Wright/Kuhns/CurtissWrightTC18/TurboCompounds.shtml<br />http://www.spannerhead.com/2012/11/21/technical-curiosities-twincharging/<br /><br />Yah I know its a bit "over-the-top" But it should answer most of your questions.<br /><br />The reason I even have any of this stuff on hand is because I have been researching about the XF-12 "RC-12" "Rainbow" by Republic Aviation. A sexy looking plan even by today's standards. I also have flight manuals discussing, in 1942 and 1954, supercharging and problems and solutions for aircraft engines. Its a hobby.
