[@animusfoxx6965]

This is absolutely mind-blowing, and to think that Ronald Valentine makes working engines less than half this size just throws everything I thought I knew about engines out the window.

[@MTRailfan406]

[@davelowets]

Cox engines was mass producing the TINY .010 engines over 50 years ago....There were literally tens of thousands of these things out there.

[@carbon1255]

This is the CUTEST THING EVER. Well done.

[@pleaseforgiveme717]

Carbon 12 Id assume, it's the only thing I would imagine it doing

[@Damien.D]

So cute! We're five years later, wonder if a model was build out of this engine. It would easily win cuteness award in any RC show.

[@rcdieselrc]

Yes, I understand pressure drop and flow. You use the needle to tune the engine not change the fuel tubing.

[@sunoncream1118]

can u explain wath does the combustion chamber tuning is for and how to use ? diesel are auto ignited so i suppose ure tunning the seize of the chamber to get the flash combustion a litle before top hig dead point of the piston but explain how u get to the wanted result like wich side is thighning wich is lossening, and why u expand or contract the chamber seize at that moment ^^

[@josex360x]

This might be the smallest diesel engine in the world, nice work man.

[@BrilliantDesignOnline]

Ran many an .049 back in the day, but did not know there was a diesel! So cool it starts with no glow plug!

[@peterdarr383]

the .049 was a two stroke diesel - ignition from the platinum glow wire and compression. Nitro reacts to platinum initiating combustion.

[@davelowets]

​​​@@peterdarr383it was a "semi-diesel", as it did not fire off compression alone. It also relied on a catalytic reaction (heat) with the methanol in the fuel and the platinum in the glow plug element. Edit: It wasn't the nitro that reacted with the platinum, it was the methanol. The nitro was just there as a power booster. There were classes of airplane racers that actually required a ZERO nitro fuel in those engines. The fuel was simply methanol and a lubricant. No nitro in it at all.

[@davelowets]

There was also a special head available back in the day to convert an .049 into a true diesel. They were made by a company called "Davis" i.i.r.c. It ended up a strong suggestion to replace the crank in an .049 also when converting to a diesel, because the factory crank was known to break from the increase in compression when used with the diesel head conversion. The aftermarket crank came out shortly after the head did.

[@petegower]

Takes me back to when I was a teen age aeromodeller. I once took a Mills .75 cc diesel into my local cinema, and started it, during a quiet and tense part of the classic Hammer House Of Horror Film, DRACULA.. It didn't half cause a commotion in the stalls. I think that was the high point of my teenage delinquency.

[@nosbig11]

brilliant!!

[@davelowets]

Hmm, strange thing to want to do.... 🤷🏻

[@petermainwaringsx]

@@davelowets It was of it's time Dave. It was the sixties and whilst I was causing a disturbance in my local cinema, older teenagers were experimenting with drugs. 🙂

[@rcdieselrc]

The compression ratio is adjusted by the screw in the head. The top of the cylinder contains what is called a contra-piston which moves in the cylinder to vary clearance volume.

[@Sausketo]

Wow, incredible design

Awesome video and i like That Diesel Engine Model of yours!

[@kermittwitlow7080]

Ha were did u get that

[@capatainnemo]

Kermitt Witlow he probably built it

[@rcdieselrc]

capatainnemo I must have missed this one. I didn't built this. These were produced by Allison Engineering in the 1990's. They had a range of displacements 0.1, 0.2, 0.5, 1, 1.5, and 2.5CC. These can only be found second hand today and many if not most are held by collectors.

[@rcdieselrc]

Mihail Stefanov Thank you. I am planning a how it works video and possibly a build video, though I did not build this one.

[@yahatinda]

MANY years ago I flew control line with Davis, the guy who makes or made diesel conversion engines for years, in Highland Park in brooklyn,N.Y.

[@Gaark]

thats ridiculously cute :D

[@Ligma_Balzach]

By far, the neatest thing I've seen on YT lately. Nicely done!

[@rcdieselrc]

Heat due to compression causes autoignition of the air/fuel mixture.

[@thebrakecutters5650]

see now that makes sense, i was a little retado when i couldn't figure out why no sparky spark...

[@TheBiarsamex]

Amazing, I knew and had only the glow plug engine in planes with line, I just knew these diesel engines in books, works only with compression.?? What is impressive is the size of these engines and they make perfect combustion, I flew a lot my planes and always impressed me how well they flight, im from ’74 and in the 80’s were an awesome entretainment.. very cool video

[@rcdieselrc]

TheBiarsamex Yes compression ignition. The fuel contains ether to help start the engine.

[@TheBiarsamex]

rcdieselrc thank you.!

[@rcdieselrc]

After ten years of electric models you'll miss the mess like I did.

[@hecker4758]

You guessed that right Very true

[@diversityhdd]

It was no mess and Yep we miss it

[@zayyandzikraka3833]

I enjoyed electric planes a few month back, now i fly my old glow models.. the sound and smell just amazing

[@vineettopno1680]

true

[@davelowets]

Yep. Electric is just missing TOO many of the things involved with nitro to me

[@weelianocraft]

I remember those P.A.W. diesel 10 size engines on control line Combat planes more than 20 years ago. It ran on castor oil and nitro mix, those engines were small but they made a huge racket! Good job on your little diesel engine!

[@funnyfailer99]

Make a v12 and put it in a scaled rc super marine spitfire :D

[@hopeso]

I have one in development but it's a two stroke.

[@politicallyinaccuratetoast4757]

[@thomasrose6962]

its interesting how playing with the comp ratio is part of the tuning process

[@mikeg3529]

What does that screw on the head do? Adjust the compression?

[@slerbahuuli]

i am wondering the same thing...

[@jangisgand6140]

Michael G Yes, it does.

[@AMILAL1000]

Michael G it controls the compression ratio of the combustion chamber .when he tight it engine speed ups

[@hondamannen1]

as you can se on the prop, it is made to drive the air to the back of an plane. in the rotation you start it, it blows the air to the front, that the oil is spued on the wood is becauce it has a lot of speed out of the engine. ask any "RC knowing" person and they tell you the right rotation of your nice motor.

[@blackdeck9112]

Will this fit into my Honda? Also is it compatible with my rear spoiler and the flame sticker on my hood?

[@uuuultra]

It would probably be faster than your Honda

[@derSkedda]

+uuuultra dos id hav V-TEC?

[@anronioruiz9244]

[@rcdieselrc]

That is unburnt oil which is mixed into the fuel because it's a two stroke. It doesn't run hot enough to burn it.

[@SuperSpetterpoep]

Now turbo it.

[@tebibyte2357]

Buy one of those turbo key chains

[@necrothescistt8164]

And put 8 inch pipes on it

[@integrationofmanandmachine4714]

You can't turbo two stroke smh

[@NutScrewGamer]

Nitrous oxide yes?

[@daTroost]

I like that you don't need a battery and glow plug to start it! Cool.

[@catalinoprea7637]

in future we will have cars with these small engeins wich use just a 2 ml of diesel or petrol if they keep up the prices at pump:)

[@iinvokemyfirstamendmentrig7937]

[@9102jack]

That's a nice little engine! I've always been fascinated at how much noise such a small collection of parts ca make! Take a COX Baby Bee for example!

[@3ccdmike]

the .049 yes

[@rizkiyoist]

When VTEC kicks in 0:52

[@rcdieselrc]

It's a compression ignition engine. When a given volume of air is compressed it's temperature rises, in this case high enough to ignite the fuel.

[@Clapham888]

Very nice, I'm impressed! Out of curiosity, would it be possible to trace the build diagrams for it? This would be a great little project for a hobbyist fitter & turner. Also, 18k RPM - Diesel. That right there is awesome.

[@rcdieselrc]

That tube at the front of the engine is the intake. The exhaust is the wider slot around the cylinder, there is no manifold or muffler. This is a simple two stroke engine.

[@nick_nt7574]

This will replace my vtec engine.

[@rcdieselrc]

It's not an injected diesel. The air in the cylinder is already mixed with the fuel so when the heat of compression ignites the fuel it burns very quickly. Model engines dues to their small size allow very high RPM and still stay within the strengths of the materials and piston speed limitations.

[@abledv872]

[@vantrongkiet]

i love the way you use the spring to start, not easy to find out

[@jomelle012]

AHAHAHA IT NEEDS TO REFUEL! thats too fucking adorable holy shit

[@rcdieselrc]

I'm not sure what you're saying. The RPM that the engine reaches when fuel runs out is not possible by needle setting while it's running. I think this has to do with the oil in the fuel.

[@krissaudiosurfchannel5240]

this is adorable.

[@rcdieselrc]

I do use the starter spring. You wind it against the spring and the spring spins it in the proper direction. This was only the second time running this engine so I was still sorting it out.

[@mvstahl1233]

Sins it is deisel you can run it off of cooking oil

[@rcdieselrc]

These were produced in the 1990's by Allen Engineering in the UK. They are not produced anymore and can only be found second hand. They show up on Ebay a few times a year. AE also made 0.2, 0.5, 1.0, 1.5, and 2.5cc engines in this style.

+FudgePc Elitist Living on the edge! Would you believe I also bathe in toxic dihydrogen monoxide regularly? Or risk my life with all the nutcases on the roads? I once even cut a tag off a mattress.

[@ArnoldsDesign]

+rcdieselrc You're right on about dihydrogen monoxide toxicity. I found some info a while back on this potentially deadly substance: "Dihydrogen monoxide is colorless, odorless, tasteless, and kills thousands of people every year. Most of these deaths are caused by accidental inhalation of DHMO, but the dangers of dihydrogen monoxide do not end there. Prolonged exposure to its solid form causes severe tissue damage. Symptoms of DHMO ingestion can include excessive sweating and urination, and possibly a bloated feeling, nausea, vomiting and body electrolyte imbalance. For those who have become dependent, DHMO withdrawal means certain death."

[@Gaark]

[@osatech1270]

hhhhh loool nice one dude

[@shaunredmond1619]

as you can see the block of would is also screwed to the desk or the vibration alone would make that small peice of wood move

[@danielhowe3516]

This is not a diesel engine, this is a nitro engine. it is a carburetted two-stroke. Diesels rely on high pressure injection, atomisation of fuel and high cylinder compression ratios to achieve combustion.

[@rcdieselrc]

Daniel Howe Thank you for your comment. It's called diesel and always has been in the modelling community. It is a carbureted compression ignition design burning kerosene and ether based fuel with no glow plug. These existed many years before glow engines. Today this type of engine is called homogeneous combustion compression ignition. The glow engine also falls under this category. Direct injection diesel are different.

[@ZYGTropicals]

You tell 'em rcd!!!!!!! Yeah buddy!

[@HexterTheJexter]

Wrong AGAIN! Its a REAL Diesel i.e. Compression ignition.

[@Misfitpathfinder]

rcdieselrc so it runs like a two stroke diesel but is it actually running of diesel or kerosene?

[@rcdieselrc]

Kyle Schumacher The key is compression ignition. The fuel is not really relevant as most any engine will run on almost any fuel with minor adjustments. In this case, model diesel engines use fuel that is suited to lower compression pressures and temperatures.

[@gamerpaddy]

what about a servomotor controlling the screw?

[@xistsixt]

Ishaan Bellic maybe those micro small linear servos would make it....

[@villelehtinen7717]

When turning the screw, you must also adjust the compression to get the revs right. So no.

[@gamerpaddy]

with screw i meant the lever for compression.

[@rcdieselrc]

It has been done before. reducing compression reduces power output. On small engines this is acceptable.

[@AMILAL1000]

rcdieselrc not only for small engines also for bigger engines . But problem for bigger engines is that there is no way to continuesly change the compression ratio . But recently heard that some japanese company has found a way to do that

[@toenoblefb8627]

Failed start attempts sounded like someone farting.

[@rcdieselrc]

I understand engines and how they work. You made a comment in reply to another comment about how it ran a little faster as the fuel ran out. I'm telling you for the 4th time, this peak RPM as fuel runs out IS NOT POSSIBLE by adjusting the air/fuel ratio. I would be interested in seeing a video of your 0.1CC engine running.

[@huntergossett4281]

still more torque than a honda......

[@oldassaccount9034]

2:37 now it starts to sound like a wankel engine :D

[@rcdieselrc]

It seems that way, but I can't get that RPM by leaning the needle. I'm not sure what's happening, but I've experienced this before.

[@panutsik]

Это не дизельный, это компресионный двигатель. И в состав его топлива, солярка не входит :))

[@rcdieselrc]

Yes of course. Compression ignition model engines such as this have been called "diesel" since they were created in maybe the 1930's.

[@panutsik]

rcdieselrc Это двигатель с калийной системой зажигания...

[@rcdieselrc]

This engine uses fuel containing kerosene, diethyl ether, and oil.

[@panutsik]

rcdieselrc Yes of course. :) We understand each other.

[@rcdieselrc]

OK! Your last comment translated to something about potassium(?).

[@TheNoisePolluter]

Cool! You could put it in a small boat and have a neat little bath toy!

[@jjhack3r]

no glow plug? how does it even start when cold?

[@rcdieselrc]

Compression in the cylinder increases temperature above the autoignition temperature of the fuel.

[@jjhack3r]

+rcdieselrc must be pretty explosive stuff then lol

[@normdoty]

compression generates the heat to ignite the fuel air mix. the fuel is not pure diesel fuel, its a blend of diesel + oil + either. some people don't use the oil they consider the diesel lubricant enough. the either thins out the diesel and lowers the ignition temp.

[@lovepreetsingh-tb2fk]

[@rcdieselrc]

[@glfsn]

Fantastic. sounds like it is running rich though. When you restrict the fuel flow to kill the engine the RPM picks up before it stops.

[@elisheffer6049]

How did I search Wärtsilä RTA96-C and got to this?

[@rurruth]

diesel runs without spark. this low compression proprieties self ignites the chamber. I think the part on top is intended to adjust the compression rate at current temperature of piston. diesel and two stroke engines can use less parts and be more cheap/easy to build

[@rcdieselrc]

Model diesel engine run a mixture of castor oil for lube, kerosene, and ether. kerosene is slightly lighter than diesel, and the ether allows for cold starting and easier running and tuning.

[@familywall]

Excellent video, I have one very similar. You do realize, however, that you are spinning it the wrong way - The propeller is designed that the airflow is over the engine to cool it as it is an air-cooled engine...

[@rcdieselrc]

+familywall The propeller is wound against a spring against the spring, when released the spring starts the engine in the normal direction. I assure you it's running in the proper direction.

[@familywall]

+rcdieselrc Hi, I'm happy to be wrong - everyday is a learning day. Now that I've looked again, I can see that you compress the engine to get it to fire 'backwards' so to speak. Thanks for the update and growing my knowledge. Best of luck with the engine.

[@stevemaines4038]

I once owned one of these and mine came with a tiny fuel tank on the rear of the crankcase. I used the 3" prop that came with the Cox Tee Dee .010 engines and I was able to start mine in my hand. More of a novelty than anything useful, but still cool.

[@rcdieselrc]

@@stevemaines4038 Yes the tank is there. It's just too small to bother with on the bench. I intend to make a larger tank. The Cox 3x 1.25 is used in this video. I still haven't built anything to fly it.

[@gregorykern9679]

This engine probably makes more power than the cars that drive slow in front of me every day.

[@akshay.kumar.k]

In my opinion, one very useful application of this would be a *Portable Pocket Diesel Generator*, with a reduction drive and a dynamo, for the camping/hiking folks.

[@rcdieselrc]

In theory, but this makes so little power you're better of carrying a battery bank or spare batteries.

[@rcdieselrc]

AE, Allen Engineering made these in the 1990's.

[@rcdieselrc]

Diesel is compression ignition. Compressing a gas increases it's temperature. In a diesel engine this temperature is high enough to ignite the fuel.
