Well I had no idea those were referred to as "rotary" Welp.

The sopwith camel had what was called a "total loss" oiling system, e.g., oil ran into the engine and then sprayed out of it into the air. Since these planes also had open cockpits, the pilots inhaled/ingested quite a lot of castor oil on every flight. Castor oil gives you diarrhea something fierce, but the pilots soon figured out that a good treatment for diarrhea is gin. During WWI it became completely ordinary and commonplace for all sopwith camel pilots to get drunk before going on sorties.

This is the best thing I've heard about gin (and the British military) since learning that the gin in a gin and tonic was originally the mixer. That is, gin is in a gin and tonic to cut the tonic and not vice versa.

Motronic posted:That really doesn't look like it should work at all. It makes sense if you just follow one cylinder around and watch the piston movement. Interesting tidbit: Both rotary and radial engines all must have odd numbers of cylinders (even the bigger 14- and 28-cylinders engines you see in WW2 were in rows of 7). Discuss.

 had this all typed up last night, and never clicked submit.dissss posted:I've never heard of anyone breaking a throttle cable on a Japanese car, even an 80s model with hundreds of thousands of kilometers and no one pro-actively replaces them. I had one fail in an odd way on an 88 Honda Accord - it wore through the plastic sheath right at the firewall, and frayed, and got jammed. I wound up loving with it until it would idle at about 4000 RPM, and just shut it off at red lights. Drove it like that for a week or so, it would do about 50-60 in 5th like that. I could give it more gas, but backing it off required pulling over and forcefully pulling the cable back through the firewall. I also had the clutch cable snap on that car once, so I'd shut it off at a stop, put it in 1st, and start it when it was time to go. I'm amazed how durable that starter was, it never hiccuped despite me using it to move the car around my apartment parking lot for over a month after the timing belt broke (apartment had some rule that a car couldn't sit in the same spot for more than a few days). Mileage was unknown - carfax didn't exist when I bought it, but the odometer showed 130k. When carfax finally did come out, I found out its last inspection (in loving Minnesota) had an odometer reading of 180k.. 5 years prior to my buying it. Aside from the timing belt breaking (and somehow not bending any valves; mechanic insisted on lining it up and doing a compression check before doing a teardown), and the alternator taking a poo poo in the middle of a 650 mile road trip (it would still charge above 4000 RPM, so I spent the rest of the trip in 4th gear), the drat thing never let me down. It was bitchy, and I suspect it had a bad cam position sensor (sometimes it would be really hard to start, and sometimes it would start jerking really bad for about 30 seconds complete with the tach going apeshit, then the CEL would pop on and it would drive fine afterwards), but it was reliable. It also gave me random showers going around turns in the rain, since the sunroof drain tubes were clogged to poo poo. Fucknag posted:Probably dropped a DBW engine into a car with a cable throttle and didn't want to redesign the throttle system to accommodate a matching pedal assembly, last model year or two of the chassis or whatever. The first year of the Saturn Ion (and I assume the Chevy Cobalt) used a cable throttle. They switched to DBW in 2004. Then switched up the automatic transaxles for 2005 in the Ion (the manuals are the same Getrag F23 that was used in the Cavalier, Grand Am, etc). My boss has a 2004 Ion sedan. It's a pretty unique unicorn - it's the first year DBW, but still has the 5 speed automatic Aisin-Warner automatic (AW55-50SN - which was only in 03-04 Ion sedans, not coupes). You absolutely want to avoid the 03-04 Ion coupes with an automatic, they used a very weak CVT (it's easy enough to swap in the Aisin-Warner 5 speed auto when they fail, it bolts in, just need to swap the TCU and some wires IIRC). He's mentioned he doesn't like how it shifts (which is a common complaint, and why GM dropped the 5 speed Aisin auto for their own 4 speed), but his average MPG is better than what I get in my 06 coupe with a manual transmission. His is also the relatively rare "Ion 1" - meaning it has a radio and not much else (the 2 is most common - power locks, power mirrors, optional power windows, CD player). I'm actually surprised it even has a/c, since he (and the car) lived in Detroit most of his life until this year, and the car was purchased new in Michigan. I don't see a/c being needed in that area most of the year, and I know a/c was optional on the Ion. Speaking of, I've offered to track down a new front bumper for his - he had an "oops" with another car, but only the bumper cover was damaged. I'm wondering if I can fit one in my car, if I yank the sub, fold down the back seats, and fold down the front passenger seat (it folds flat).  I need to make a junkyard run soon anyway.

Computer viking posted:To avoid a stall situation with two exactly opposed cylinders? I think it's due to the Otto cycle. In a, say, 7 cylinder rotary engine, the firing order will be: 1 - 3 - 5 - 7 - 2 - 4 - 6 ensuring an even distribution. A hypothetical 8 cylinder rotary engine would run rather rough: 1 - 3 - 5 - 7 - 2 - 4 - 6 - 8 the 8 - 1 would mean that every other revolution you'd have two cylinders in succession firing.

bolind posted:I think it's due to the Otto cycle. In a, say, 7 cylinder rotary engine, the firing order will be: Wouldn't the firing order be 12345678, as the different cylinders passed the fixed ignition point in the rotation (Ref Quark's movie above)? Ofc, that invalidates my "opposed cylinders at the same time" idea, too.

I struggle to see how it would work out if you could have ignition at any point other than just past maximum compression, and that's at a fixed point in the rotation.

The best radial engine starts are the ones that use a "shotgun" gunpowder or cordite charge, such as the so-called "Coffman" engine starter. https://www.youtube.com/watch?v=65qrzgbTTcQ

Absolutely, and in fact that's the very scene in which I learned that that kind of starter existed. Definitely watch the original it is great.
