废食用油代用燃料在柴油机上的试验研究

Study on the Use of Alternative Fuel Made from Waste Vegetable Oil in the Diesel Engine

食用植物油是一种很有前途的代用燃料，它是利用植物的光合作用不断更新生产的一种能源。通过用废食用油制得的柴油机代用燃料，在小型高速柴油机上与0号柴油做了性能对比试验。试验结果表明，与燃用柴油相比，用废食用油作为代用燃料输出功率几乎相同（仅低2%），燃油消耗增加了6%-12%，排气温度降低了20℃，所排出的CO2降低了10%-15%，CO降低了10%-18%，HC降低了47%。

As a useful alternative fuel, vegetable oil is a kind of continuous renewed energy sources made from photosynthesis. In the paper, a performance comparison experiment of two kinds of fuel, alternative fuel made from waste vegetable oil （WVO） and No. 0 diesel oil, was conducted in the small type of diesel engine. Results showed that the alternative fuel is fit for the diesel engine. Compared with diesel oil, in the export power of the engine, the WVO is much at one （only reduced 2%）, and fuel consumption increased 6% - 12%, exhaust gas temperature decreased 20 ℃, CO2, CO, HC concentration emission reduced 100%- 15 %, 10 % -18 %,47 % respectively. The theory on searching for alternative fuel using in diesel engine was also provided.
