另類思考, 用體積比例當成份計算....
節錄自Model Airplane News(Jan.2010 page 46), 由Dave Gierkei所發表的文章" Fuel Facts", 同時紀念引擎老先覺Chris Chianell , 小弟特將它整理如下 :
FUEL BLENDS ARE FORMULATED BY COMPONENT VOLUME, NOT COMPONENT WEIGHT.
--------------------------------------------------------------------------------
Ringless Piston(ABC,ABN,AAC), Ball Bearing Supported Crankshaft
Nitromethane Oil Contents Total Oil Mathanol
Synthetic /Castor
5% 14%/4% 18% 77%
10% 14%/4% 18% 72%
15% 14%/4% 18% 67%
20% 14%/4% 18% 62%
25% 14%/4% 18% 57%
30% 14%/ 4% 18% 52%

The Relationships of Displacement and Lubricating oil / Nitro percentages:

以上比例是以體積為成份比例計算的, 另類思考, 跟各位分享!
