I know several places up here with R-2000's, R-2800's, and even few R-4360's in various states of disrepair. (we still use DC-4's and DC-6's up here...and once there were quite a few KC-97 types) ...

I know they made both 11 and 12 cylinder versions (Alcoa had bought some of each, according to the book I was reading.) ...but I have no other info, so the additional info you provided is much apprec ...

I suspect it was flared off as leaving it to evaporate could result in an uncontrolled burning/explosion if anything ignited it....and in the days of oil lamps and steam powered drilling rigs, ignitio ...

I've never seen one of those Nordberg radial diesels that I mentioned before, but I am sure everything about them was massive....you are correct that the bearing area would no doubt need to be huge to ...

WS-110 was the weapons system for the B-70 Valkyrie...once the ws-110 system was cancelled, the XB-70's were used for research and testing only. The atomic powered aircraft used a gas turbine whose h ...

Anybody familiar with Wright Aeronautical's venture into marine engines? I found a reference to a 1925 vintage V-12 of 600hp ...looks like it has a dry sump, cast cylinder blocks bolted to the crank ...

I think very few of these got put into aircraft service...most of these ended up as the T-1020 which was used in tanks...our local museum has one of them on display. Although the service interval woul ...

I did a little more searching, apparently Nordberg made a successful 11 cylinder radial, but it was for industrial purposes...They were used for running generators (in a vertical shaft arrangement) In ...

I've never seen one referenced in any of my books...I suspect the reason for this is that the additional cylinders would dictate a larger diameter engine to make room for them all...this would increas ...

thanks! ...I would not have expected it to show up in pre-ww2 tank engines.....but then again, I sure did not expect to see it on a ww1 vintage stationary engine either. Perhaps this is a far more c ...

I am wondering when ADI (anti-detonant-injection) first came into use. I have a theory that it was NOT originally used in aircraft engines. My reasoning for this is that I recently added a 1917 Fair ...

It seems like I recall something I read about some experiments done with either the Allison V-1710 or possibly the Packard Merlin V-1650 to run in an inverted position as the DB605's, etc did. The ob ...

I don't know the inlet temp at the valves, maybe I can try to measure it this winter...no, mine is not aftercooled.....as for the steam engines this makes sense because the condenser creates a vacuum ...

Nope, no reduction in smoke with rpm drop....if I let the engine warm up a bit, it improves somewhat but will still smoke a bit unless the ambient air temp increases. (especially if you really put you ...

I agree a hundred and ten percent on that point! I have long argued that belts should not be used on critical items like camshafts...granted, chain drives and gear drives will wear out, but they give ...
