Experimental study of application of emulsion fuel to medium scale diesel engine (direct fuel injection chamber type, serial six cylinders, compression ratio 17.0, stroke volume 10.3 litters) was conducted (2100 rpm in steady revolution) at the Institute of Mutual Engineering of Univ.of Oriente, Santiago de Cuba, Cuba. Two kinds of surface active agents of a Non-ionic synthetic product and a water solution of plant (sugar cane) pyrolysis product were compared for the stability of emulsified fuel, the engine performance and the soot concentration in the exhaust gas.Although the stability of emulsion fuel by using water solution of plant (sugar cane) pyrolysis product is a little lower than that by synthetic non-ionic surface active agent, it was shown that there is no problem in the steady running of engine. As the engine performance fluctuates over a wide range owing to the running condition and the water content (up to 20vol%) in emulsion fuel, the clear difference in the engine performance due to the kind of surface active agent could not be shown. The difference in the effect of micro-explosion on the engine performance between the two types of emulsions prepared by the different surface active agents could not be shown. Soot concentration in the exhaust gas fluctuates over a wide range owing to the running condition of engine and the water content in emulsion fuel. Thus, clear difference of soot concentration due to the different kinds of surface active agents could not be shown.From this study, finally, it was shown that the water solution of plant (sugar cane) pyrolysis product can be used as the emulsifier for fuel of diesel engines, and more work is needed to examine the effect of surface active agent on the stability of emulsion, engine perfoamance, soot concentration in the exhaust gas.

在古巴圣地亚哥东方大学共性工程研究所进行了乳化燃料在中型柴油机(直喷室型，六缸串联，压缩比17.0，行程10.3升)上的应用试验研究。比较了非离子合成产物和植物(甘蔗)热解产物水溶液两种表面活性剂对乳化燃料的稳定性、发动机性能和废气中碳烟浓度的影响。虽然植物(甘蔗)热解产物水溶液的乳化燃料稳定性略低于合成的非离子表面活性剂，但对发动机的稳定运行没有影响。由于运行条件和乳化燃料中的水分含量(高达20Vol%)，发动机性能的波动范围很大，因此表面活性剂的种类对发动机性能的影响不明显。不同表面活性剂制备的两种乳化液对发动机性能的影响差异不大。排气中的碳烟浓度受发动机运行状况和乳化燃料中水分含量的影响，波动范围很大。本研究表明，植物(甘蔗)热解产物的水溶液可以作为柴油机燃料的乳化剂，表面活性剂对乳化液稳定性、发动机性能、废气中碳烟浓度的影响还有待进一步研究。
