Devize Engines - Axial Barrel 4 Cylinder - First Time Running- Tuned By Shane T 

Living up to the name for sure 😂😂

No real reason for 2 strokes these days to smoke at all... especially opposed pistons 2 strokes. Its probably just a matter of running very rich and untuned for this test.

Our pleasure!

Well appreciated sir

Thanks 🔥

👍🏻👍🏻

😂😂😂

My guess is that he plans on solving that issue with a temporary fix or some kind of modification to where ignition or soark issues don't occur as often

Deltic 2 stroke diesel 1950 ?

@@Whateverpoopiepants old design but new machining and new materials.

@@zonta71 I doubt it.

@@Whateverpoopiepants so what you are saying is the engine in this video was built in the 50s no worries. Moving on

@@zonta71 Don’t need to be so wet.

You are shockingly close to exactly how this is configured. Pretty much the answer to all of your suppositions is Yes. Well except for the bearing one 😂

I explained more about the engine and it’s oiling requirements in one of my other videos, but no it requires no oil in the fuel itself. The piston shown was a very early design and not precisely what is used in the finished engine. It uses dowels to keep the rings aligned so they don’t snag in the ports on the way by.

Can’t argue that point. Still fantastic to see it run at all.

Believe it or not, this does NOT use oil mixed with the fuel. They also have a 4 stroke design.

There are several steps to the process and this is just the first one. A milestone of sorts for this project some 3.5 years in design. The timing is variable by engine speed and cylinder load, typical axes for timing control on standard engines. Appreciate you taking a look and the comment 👍🏻

i think your comment on the bearing is more than likely going to be this ones achilles heel too. it wont "spin" it as such, as scuff the hell out it and the cam. they arent rolling... theyre scrubbing. think tapered bearings and why theyre tapered... that they have a common point of convergence. where does this ones bearings converge? cylindrical rollers on a radial face dont work, they scrub. and then its a cam as well. one line rolls, the rest scrubs... as it takes the forces of combustion...

I recently whatched a video on a diesel engine that was made in England used on several truck one of which logged over a million miles. The pistons met in the middle much the same only not an axial engine. The company was purchased by Chrysler and then phased out the engine. There are apparently some of these trucks in existence however they are in Australia and currently not in running condition

Achates power is already licensing similar tech to Cummins... for the ACE engine in the military for tanks etc... 1000hp 4 cyl. they also have a 10.6L and 2.7L design. Walmart and Tyson have trailed the 10.6L engine in transfer trucks fora while now.

😂😂 agree

Slowly, slowly grasshopper

@@TunedbyShaneT 😂😂😂 You guys kick ass man lol

Its definitely the spark plug wires. 🤣

There are many applications possible. Aircraft, Marine even Hybrid Automobile.

@@TunedbyShaneT It would seem to me one advantage of this design is keeping the design simple and costs low.... the US needs a locally produced small - medium industrial engine also, for tractors and the like. Companies like Big equiment company and others are trying to return control to the owners of vehicles so they can repair and maintain thier machines cost effectively rather than essentially buying license to run thier machines (which is downright evil). Thinking in the range of 40-200hp.... many companies focus on a single market and end up over optimizing for that to the point that thier engines never get used... because they lack cross market synergy to fund R&D.

I know ACHATES found some solution however I’m not privy as to what.

Similar but not the same

Axial engines have been around for some time as have Barrel’s no one has tried this exact approach yet however.

What isn’t

Just because it’s 2 stroke doesn’t mean the oil and fuel get mixed

@@trevoncowen9198 allot of smoke to say otherwise

@@jamescummings4130 on the first ever start not to mention it isn’t tuned also I don’t think u can determine the composition of exhaust through ur phone

@@trevoncowen9198 oil burns off quickly after first start, mixture has nothing to do with the fact it clearly is burning oil, go troll somewhere else

@@jamescummings4130 oh you built this engine? And I’m guessing oil burns white not blue?

👍🏻👍🏻👍🏻

Yeah it shouldn’t be smoking like that. The problem is being remedied now.

It was injecting smoke into the cylinder because of a oil pressure regulator malfunctioning

It doesn’t use premix oil in the fuel. Unfortunately due to a stuck regulator valve it was doing its own oil injecting in the cylinders. Parts are being made to correct it.

@@TunedbyShaneT Yaa I was going to say you're missing a seal somewhere...,

😂😂

One can only hope

It is not intended to be emissions legal at this point but the smoke is not normal. A regulator valve in the oiling system is the culprit. Thanks for giving it a look 👍🏻

If it was intended for smog certification that might be a problem.

ACHATES........

2 strokes could be smog legal

That exact linkage is unique and proprietary, but if you can imagine, the bottom of the extension has a roller sort of like the roller on the bottom of a conventional roller valve lifter. It rides on the face of the cam while the extension has a “knuckle” which also holds another roller on the opposing side of the cam in such a manner than as the Cam rotates, the piston is pushed up and down the cylinder.

@@TunedbyShaneT What you just described is not unique, or proprietary. It has been done for years in multiple different designs. While this is a cool, nothing mechanical about it is new. Keep in mind that the axial engine was supposed to be the next big thing in internal combustion for 100+ years. While it can have a thermal efficiency advantage, that is the only advantage it will ever have. This design is very similar to a Sterling, but you described it as having a Dyna type connection at the wobble plate. Neither of which is a new idea, or proprietary. Years ago I built my first axial engine out of an axial ac compressor. Surprisingly it worked very well, but not for long.... And that is the downfall of every axial ever designed, longevity... Who cares if it gets 100 mpg and then you walk when it breaks down shortly thereafter... Every design that has come up, failed.... You would think after 100+ years it would succeed if it was a sound design. And that is exactly why all of them fail... I too used to believe that an axial had promise, then learned from experience otherwise... Someone has else already failed with the same design people thought was unique.. Axial is probably the most tested and experimented engine design there is, which is exactly why basically nothing uses them.... They are cool thou, because they are different.
