@@288gto7 lol, i think i knew a bit more about this engine ;-) It has 2 gear driven radial superchargers . The 12cyl. MTU in the Leo2 is turbocharged. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-POgo8NLj2Zw.html
Great Video, thanks :) Few times per year i operate a big winch which is powered by 2 mechanically connected MTU MB 838 CaM-500 engines. It's a lot of fun. One engine sounds great but 2 of those, running almost same rpm, sounds crazy. Full throttle and 2k rpm is like an earthquake and thunderstorm at the same time!
2:25 Wow, i didn't know till now that even the instrument panels i work with (of course 2, which are mounted above each other) are the original panels from the tank.
Medium Tank What? Sound can be POWER! Respect from a CG* 84mm instructor Royal Life Guards (dannevang/Denmark)) 1998-2007 *M/79 & M/85...liked(did better with) the older one 😲
the engine itself isn't actually that big, from the exhaust half way down it's torque converter, hydraulics and transmission flanked by massive radiators.
@Dalle Smalhals definetly yes, on the old cats you had to remove the entire upper front to get the transmission out. Idk what the guys at Krupp and Borsig smoked when thinking about maintenance. Now since the late 50s/early 60s the Leopards and Pattons already did something similar to power pack design. But the really good powerpacks were developed for the MBT/Kpz 70 programme, though the project was cancelled many ideas were kept. And on modern packs you only need to disconnect the final drives and some of the lines and cables and take some panels on top off, iirc for a Leo 2 it takes between 30min and 2 hours, which is almost nothing compared to the many hours for one part alone with a gantry(?) crane. It's so much better, especially for our boys and girls in the field 😁
@@magnushederstjerna5975 I was talking about the physical size not the displacement. 36 liters is not that big for a big diesel engine. Finally Scania can make 800hp from a 16 liter engine.
The radiator intake is actually on the top, its the circular turbine in between the 2 radiator pack, air gets s8ucked in from the top, expelled at the side, the same fashion that exhaust is expelled. that said, I believe the way the hull was made made it impossible for the hot exhaust gases to get into the turbine fan on the top.
Actualy when the tank is swimming thé cooling is done by the outside water flooding the radiator it is Also designed the reduced the infrared signature of the exaust when on the battlefield. Thé air from thé radiateur is then mixed with the hot Exaust to cool it down sgt rod
here you can see inside the Leopard1 chassis or hull; its from a "Gepard" Flakpanzer (AA version of Leo1) but many parts are the same, especially the chassis. There is a pump on the bottom to see which can be switched on for pump out leakage water, oil, fuel and all their mixtures.....bloody hell of a job to wipe out this whole surface it was !! Back left an right the huge disc brakes from " Alfred TEVES" later Continental TEVES ; we were able to change brakepads (huge !) from behind the tank simply by opening a round plate and we get access to the brakes. There is also to see a small metal wire all around going and this is also above the engine and tranny . Its the fireextinguisher wire which works with Halon. (not allowed anymore because Ozonlayer destroying) ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-rS5ju1GE6Qo.html
It is a V10. What you see in metallic color in the middle of the engine (right above the alternator on the left hand side) are the heat shields for the exhust manifolds. The valve covers are above them, with 4 smaller bolt heads barely visible. :)
@@dbasq1 Of course it was... The quick exchange of the whole engine and transmission unit is until today a big advantage. A well trained crew of mechanics was able to do that in less then 30 minutes. Leo 2 now has a V12 with almost twice the power, 1500 HP instead of 830 HP of Leo 1. I have to correct the displacement of the engine, the MB 838 had 37,4 liters.
