O.S. Engines FS-48 Surpass Diesel Conversion & Etherless Fuel

In this video I run the FS-48 diesel conversion I did in 2006. I rebuilt it last year to replace a damaged liner and ring (unrelated to the diesel conversion). I also added the crankcase recirculation system OS uses in the new Alpha Series. Once the engine is warmed up I can switch to a fuel mix with no ether. 12% oil, 87% kerosene, and 1% DII. I did not measure RPM this time, but it has run at 10,800 RPM on the etherless fuel while turning a Graupner 12x6. Fuel consumption is on the order of 12oz (355mL) per hour at wide open throttle in flight. The compression setting is substantially higher without ether, but the engine appears to be doing well. In the past I had run the engine with 20% castor oil in this fuel. The 12% synthetic oil is an experiment at this time. Please note model diesel engines are design to run on model diesel fuel containing ether, kerosene, oil and a few other additives. It is best purchased ready to use. Fuel without ether is an experiment at this time.
