Show III. EXPERIMENT This study was constituted of many different phases directed towards one goal: proper atomization of alternative fuels in a C.I. engine. To obtain this goal, specific fuel properties, injection properties, and engine parameters were measured. The fuels tested on a volume basis were; 1) 100% Diesel Fuel #2 (DF2) 2) 10% Dioxalane/90% DF2 3) 10% MEK/90% DF2 4) 25% Sunflower Oil (SFO)/75% DF2 5) 10% Dioxalane/5% SFO/85% DF2 6) 10% MEK/15% SFO/75% DF2 7) 50% MEK/50% DF2 8) 25% Ethanol/75% DF2. Fuels 2, 3 and 4 were tested to determine if the spray pattern coefficient could correct atomization for fuels with drastically different fuel properties than those of DF2. Blends 5 and 6 were chosen because their viscosities were similar to those of DF2. Test fuel 7 was tested to observe the effects of burning a high percentage alcohol blend on engine parameters. Fuel blend 8 was tested to varify the occurrence of a vapor lock in the fuel system for ethanol blends. Fuel Properties Table 1. is a list of ASTM codes and the limiting requirements for a fuel to be classified as DF2 as set forth in ASTM D975(4). Due to the lack of equipment, the only property measured from the list was viscosity. However, higher heating value, density, -15- |
