Norvel .15 running on B100 Biodiesel fuel

This is a better clip of this engine running on 100% Biodiesel fuel. Actually, 98% as 2% of the fuel mix was Amsoil cetane booster. Still, we have virtually a one component fuel. That is, no additional oil was added for lubrication. The only lubrication in the run was provided by the fuel itself.

Testing has revealed that about 40% of the fuel is being expelled. We are assuming that this is that part of the fuel that is acting to lubricate the engine. However, it may just be incomplete combustion due to poor atomization. As well, this batch of Biodiesel may have not been as refined as it could be. We are working to perfect our production methods in the hopes that more fuel will be burned. This will include better fuel along with some mechanical modifications to the throttle and to the engine itself to try and improve atomization.

If I were you, I would use a crankcase-pulse fuel pump -and- the exhaust pressure tube, maybe even use a smaller muffler outlet for more backpressure. Then just lean out the needles, that way you don't have too much lubricating oil causing drag and muffler-goo/smoke. The perfect diesel run could be had by using heated fuel vapor instead of liquid fuel. :)

These are all good ideas. Yes, better atomization is needed by the looks of things. I've been out of action for the last two years but I hope to get back to work this summer.

One way to pre-heat the fuel would be to install tubing inside the muffler that the fuel lines are hooked up to.

Or, make a "water jacket" but run the fuel through that instead of water.

Or both strategies might be needed.

We'll see.

ams? whats that

how did u do that

It is about time someone made a renewable fuel efficient RC motor!
