Glow Engine SUPERCHARGER?
 

Ive been working with car engines and motorcycle engines for a while, i was wondering if anyone ever thought i trying to build and put a super/turbo charger on a glow engine...Is the exhaust pressure from a glow engine enough to run a turbocharger? the output from the charger can go directly into the carb for max airflow...im just wondering if anyone thought of this before...or if this is even possible...just my thoughts! :)

RE: Glow Engine SUPERCHARGER?
 

I remember seeing a thread here about a guy that made a turbo and it worked correctly.. something broke and the guy couldn't get to the cnc machines again to repair the thing....

RE: Glow Engine SUPERCHARGER?
 

Do you mean two stroke or four stroke glow engines?

Yes supercharging can be done, has been done and it has been thought of countless times so no, this is not a new idea. But it is an expensive proposition and these engine have fantastic power to weight ratios already so generally why bother.

Two stroke engines are supercharged with tuned pipes. Otherwise it is a bit tough to mechanically or turbo-supercharge with no exhaust valves and crankcase induction but it can be done to a small degree. With the small four strokes it is just a pain in the arse to make the superchargers themselves. When folks need more power from their four strokes they generally use liquid supercharging aka nitromethane. Or bump displacement. KISS principle rules. And budget.

yah i figured someone thought of it before...im running a two stroke but i would think that it could only be done on a 4 stroke cuz it has the correct cycle..but if a small enough turbocharger could be made to fit a 4stroke glow engine then would it be of any benefit? i figure just boosting the nitro % would be just slightly cheaper...

There are a couple four strokes that have super chargers. They are mecanical vs exhaust driven though. I wouldn't think that a turbo would be much use if it would even work on a two stroke though. How many motorcycles with 2 stroke engines havet turbochargers? A tuned pipe is another story though.

RE: Glow Engine SUPERCHARGER?
 

you dont see many motorcycles with turbos on them...but people have asked to fit custom ones..i worked on a bike that had one on it and i was non stop asking question about it to the owner..but yah i dont think a turbo can be used on a two stroke now that i think about it more...would be cool to see a small 4 stroke with one though...not sure if it would get a huge boost in power but ya never know :)

RE: Glow Engine SUPERCHARGER?
 

Thought the same thing, on 2 strokes th eintake and exhaust are open at the same time so a turbo wouldnt work but a 4 stroke is a completely different animal.
Bear in mind a lot of things have to change when you supercharge an engine. The pressure on the back of the intake valve is trying to force it open so it is like having weaker valve springs just to name one.
However YS 4 strokes have a unique supercharging system where the intake charge is sucked into the crankcase and blown into the intake by means of a rotary valve. Fascinating really.

Here is the 1990's OS super charged 4-stroke.

RE: Glow Engine SUPERCHARGER?
 

OS had a supercharged 1.20 four cycle engine back in the 1990's.
They used to have a RB Supercharger for radio control car and truck 3.5cc glow engines, but it looks like they discontinued it.
There were a few guys who did superchargers for their engines as a one off kind of thing.

OS, a number of years go, did make a limited run of .91 and 1.20 electronic fuel injected four cycle engines too.

The main problem is the superchargers or turbochargers to not work well on engines as the engines get smaller and smaller in displacement. Eventually you reach a point where the superchargers just do not work anymore.
For small motorcycle engines, it appears that trying to run a supercharger or turbocharger on a engine smaller than 250cc doesn't appear to yield any more performance out of the engine. I have seen a number of superchargers or turbochargers for 250cc ATV types of engines for sale though. But no one except for Peugeot has tried to run one on any smaller size engine (Peugeot did sell a 125cc engine with a turbocharger or surpercharger on it in Europe).

RE: Glow Engine SUPERCHARGER?
 

The problem with a turbo-charger on our model engines is the oil in the fuel, it creates so much drag as to render the turbo useless. On the exhaust side the oil would have to be forced into the center of the wheel. ( against centrifugal force), to exit the exhaust pipe and on the compressor side the oil would collect on the outside end of the compressor vanes, the worst possible place for it to be. As you can see the exhaust flows from the outside in to the center on the turbine side and from the inside out on the compressor side.

This has been discussed over and over again in the car engines forum. RB Innovation supercharger has been available for car/buggy engines for several years now and even though it looks cool and showels air, it simply can`t work it`s magic on a twostroke where the exhaust port is the last one to close. The pressure just escapes out before it closes. In a couple of words: wasted money! Only for the cool looking bling-bling effect;)

RE: Glow Engine SUPERCHARGER?
 

I have an electric driven supercharger. It was only produced for a short time before all the 'bad vibes' from internet experts killed it. :eek:

It looks cool. I can say for a fact it does not hurt performance. I cannot say it makes more power than dumping extra nitro in would do.

When using the supercharger, I can open the HSN 4 more turns to compensate. Without it in operation, if the HSN were opened 4 turns more the engine would barely run.

So, it is doing something about adding more air.

In any case, more power or not, I dig it. It is neat looking, and just another cool accessory to have on a blinged out engine/car. :D

RE: Glow Engine SUPERCHARGER?
 

That is really clean looking supercharger on that car there kmot. so it does look like a super or turbo is possible just not as efficient in the smaller engines let alone a 2 stroke...just add more nitro...thats what ill do for my planes lol.

RE: Glow Engine SUPERCHARGER?
 

YS 4-cycle engines are supercharged using a crankcase supercharging system. Also, some of them are fuel injected, like the YS 170-DZ. The YS 170-DZ/CDI also has ignition. There you have it, one engine that is the complete package.

Here's a couple 2 stroke turbos for ya...[link=http://www.boondockers.com/turbo/turbo.html]boondocker's turbo[/link]

Superchargers or turbochargers are specifically prohibited in AMA control line speed.

RB also sells Nitrous systems

RE: Glow Engine SUPERCHARGER?
 

now someone should stick that on a .52 4 stroke and see if it does anything

Those things remind me of the old saying that 90% of fishing gear is designed to catch fishermen rather than fish.

RE: Glow Engine SUPERCHARGER?
 

That super charger costs $150 and a nitrous system is $175

RE: Glow Engine SUPERCHARGER?
 

From what I remember from mine, the old OS 1.20 had a genuine Roots type super charger. Albeit, simplified.<div>YS engines (certainly all of mine) don't and have never had, a super charger.</div><div>Instead, their design gives a type of super charging effect.</div><div></div>

RE: Glow Engine SUPERCHARGER?
 

Supercharging is an effect. If you pack more fuel air mixture into the engine than it can naturally induce then it is supercharged. The method does not change that.

RE: Glow Engine SUPERCHARGER?
 

This is nice....

RE: Glow Engine SUPERCHARGER?
 

Forced induction on a 2 stroke....

Can’t see why it wouldn't work with a tuned pipe.

Would be an awful waste of fuel when it wasn't on song. :D
