9 Craziest Engines You Can’t Buy Today

[@RobynTapps]

That bike doesnt have a rotary engine.... Its a radial engine from an aircraft.

[@scootergeorge9576]

Correct. With the rotary engine the crankshaft is stationary and the cylinders revolve. Quite conman in WWI aircraft like the Sopwith Camel and Fokker Triplane.

[@rayg9069]

Yep, it's a pair of 6-71 GM Diesels mounted to a common gear case, they were used in tanks possibly Shermans?

[@CaberFeidh]

That first one is the twin-671 pack that powered the M-10 "wolverine" AT-SPG. Dodge had nothing to do with it... which should be obvious, since it actually runs

[@aussiebloke609]

[@marcconyard5024]

The sleeve valve radial was perfected by Bristol. First came the Hercules then the Centaurus.

That first engine is a twin Detroit Diesel 6-71 commonly used in boats.

[@buellfuel2001]

The first engine shown was a Detroit Deisel 6-71 tandem. They originally used 2 Detroit Diesel 4-71 in the Scenic Cruiser bus both to get it rolling then kicked one out at cruising speed. I have worked on the Ford 427 SOHC.

Thanks for taking the time for us thanks again

[@RevAldea]

You say this first is a Chrysler 30 cylinder madea from five 6 cylinder Plymouth flathead power plants but the first part of the video is showing a two GMC Detroit 53 series power plants configured as one power plant block assembly both engines I have seen for my self, back in my per teen years, I'm now 80 years old this year. it seems that someone has confused the timing of video with the timing of Notices. Sorry but this is true!

Rev I'm 85 this year and they're 71s not 53s. I've ran, taught, and maintained both.

[@MrCarnutbill67]

Flathead huh? What’s with the valve covers then? I worked on aircraft tugs that had 1953-54 Chrysler flathead 6’s in them and that ain’t it. Lol

[@jacquesblaque7728]

I suppose that by now someone's 'splained the difference between supercharging and mechanical scavenging. Detroit Diesels like this, being mechanically scavenged, have that service provided by the Roots blower. Any supercharging would be purely accidental. FWIW some Cleveland Diesels (locomotive engines, much bigger) are turbocharged, having crankshaft driven scavenging blowers to run at low speed/power to get them up & going.

[@billyshafer3182]

That is what they are. I worked con 671s in the Navy. If it is a gas engine. Where are the spark plugs.

[@johnlopperman2161]

ashole Not superchargers, but scavenging air blowers.

[@1972moonbeam]

The first engine is actually a set of twin 671 Detroit diesel one is a right hand drive and the other is a left hand drive. All 2 stroke Detroit’s run a blower because they don’t run intake valves. This set up was used on drilling rigs for running the mud pumps

[@skulz1974]

Thats not a mulitibank : its a Detroit twin-six.

[@aussiebloke609]

The Cizeta didn't have a central gearbox - it's a central flywheel and power takeoff to avoid flex from having a too-long crankshaft. The gearbox took power from this central point, but it was definitely not a "central gearbox, with a V8 on either side of it..." as there is no way you could fit two V8s _and_ a gearbox within the width of even a ridiculously-wide car like this (remember, the "T" in V16T stands for "transverse" - the engine is sideways across the car.) The gearbox was just behind the engine in the usual position.

[@JohnW1711stock]

The engine in the JRL Choppers bike, is not a rotary, It's a radial aircraft engine.

[@yeahimere9631]

John W 1711 Stock. You're right, a rotary aircraft engine has a static crankshaft that the block and cylinders rotate around.

[@alanhawkins4841]

The fist engine is a parallel Detroit Diesel 6- 71

[@dougb6239]

Yeah, you can very clearly see the infamous 6/71 blower, aka supercharger , in plain view. I was thinking Detroit!!!

[@swnorcraft7971]

With a rotary radial engine, the cylinders arrangement would have to be balanced. On this bike, they probably had to balance the crank, rods and pistons..... since it was running in the inverse of how it was designed.

[@ronmartin3755]

The Motorcycle engine is not a Rotary engine it is a radial engine!

[@jhfl1881]

and you can still buy it too. The Aussies make them.

[@larrygall5831]

@ 2:19 ..It's a *radial* engine, not a *rotary*. Big difference.. rotary engines have a cam instead of pistons / cylinders. Radial, found in aircraft, have multiple cylinders that radiate around the crank (in a circle).

Far too many mistakes here, so many it gets a thumbs down from me.. The Merlin is no crazy engine, it was a war-winning engine which continued to be used in detuned Meteor form in Centurion tanks into the '70s. Hundreds of thousands were made during and after WW2, there are lots of them around still. If you have lots of money, you can buy one and fly. The Commer engine was unusual, but not crazy. It was a successful and well-like lorry / truck engine of its day. Efficient, reliable and sufficiently powerful. I could go on, but it gets boring But, what is that pic you used for click-bait? It looks like a V16 with four motorcycle cylinder heads

It's a Detroit Diesel twin 6-71. Used in tug boats, IIRC.

[@bulta209]

Every one of these engines can be bought today. BS video.

[@fredericrike5974]

Your bad research, or complete lack there of, gets an F minus as a grade. The Twin Six in the first clip has not been available since the late '40s as surplus; the straight six SC diesels it is made from have been out of production since the mid"60s- you can get a gasket set from specialty mfgs, but even pistons are made to order. Panhard as a brand died before 1960, no whole engines or parts available except through specialty brokers. The 427 SOHC engine in the clip was built by Ford to compete at NASCAR against the MOPAR Hemis- not in production since 1969, and even then only a few hundred ever made- the Kasse engine you refer to is from later model parts and has no kinship with it. You are correct- this video was shot through with errors, just not what you seem to think.

The Rhone rotary engine was built in France back in the thirties. The entire engine and propellor assembly spun around the crankshaft.

The first engine was two 6-71 Detroit Diesels (6 cylinder, 71 cubic inches per cylinder), mated to a reduction gear for marine applications.

[@rhondal1]

The first engine was a Detroit Diesel twin. We had twins and quads for mainly government use. We used inline 6-71's. I worked at Detroit Diesel for 32 years.

In order for the engine on the bike to be called a rotory, the crankcase would have to spin on the crankshaft. I just verified it on Wikipedia.

[@Christopher0184]

Rotary engine is a term borrowed by the modern car industry from the aircraft industry, and it is technically a rotary engine. The engine that powers Mazda RX-7s is a Wankel engine. So stop trying to correct this guy when he didn't actually make a mistake.

Christopher0184. No, the engine in the bike is a radial engine, a rotary engine's block and cylinders rotate around the static crankshaft. Do some research and get your facts right , dopey!

[@lindamcentaffer5969]

Aaaah the Wankel IS a Rotary. I think ya ought to EDUCATE yourself in this field! The only ROTARY engines used in airplanes, was in the World War 1 era, where the RADIALLY arrainged engine"s CRANKSHAFT was actually bolted to the firewall via a flange on the aft end of the crank, while the engine ROTATED around the crank shaft. The French made Gnome was a prevalent brand then, and the type was known as a ....ROTARY! The more modern types of "Radial - cylindered" engines, where the crank case is bolted to the firewall, HAS BEEN since around 1920, called a RADIAL engine. The Wankel has, because it's crank shaft is "weird," as long as I can remember, always been called a ROTARY. I have gray hair, and you're the first supposed "authority" in the field of engines I have ever seen get confused over this issue. Advice: when many people say you're wrong, research and learn. Then, ya MAN UP & admit it. Much more respectable that way.

That motorcycle is confusing the shit out of me. If that's not a radial aircraft engine, why does it look exactly like one. If it's a rotary aircraft engine why are the cylinders stationary? If it's a Wankel type rotary engine, why does it have a bunch of obvious cylinders? Are you ignant or have I gone mad?

[@aussiebloke609]

He's ignorant. This is a simple radial engine. Mind you, there were radial engines that were referred to as rotary (before the Wankel design started using the term), but in those cases, "rotary" meant that the entire radial engine spins on a stationary crankshaft. It's an old idea that made it onto a few aircraft - biplanes, if memory serves - and the design didn't last long because the design limits RPM significantly.

[@DaveBassTrekker]

R2800 "generally quite poor" - In what way? RADIAL engine with 2800 cubic inches and rated at 1500hp to 2250hp, depending on aspiration, water injection and fuel deliver systems applied. Was used in high performance FIGHTERS like the Vaught F4U Corsair, the Grumman F6F Hellcat, Republic P47 Thunderbolt, as well as several other high profile attack, bomber and cargo planes. Had more torque than you'd know what to do with and was reliable for 15 hour flights. No car engine could take the punishment an airplane engine endures. Quite poor - my Aunt Fanny.
