乙醇柴油替代燃料排放功效及热力学效率计算分析

Thermodynamic Analysis and Emission Calculation of Diesel Engine Using Ethanol Diesel-oil Alternative Fuel

对辽宁海事局30 m级海事巡逻船0210轮主机进行热平衡和火用分析,获得该主机各部分热量损失和火用损失分布情况,对于采用替代燃料——乙醇柴油进行热力学分析和排放估算,计算结果表明:在保持燃料火用和有用功不变的条件下,采用乙醇柴油时发动机所耗燃料增加3.456%,热效率微增,而二氧化碳排放量有了较大幅度的减少。

The thermal balance analysis and exergic analysis of the diesel engine for the 30 m class patrol boats are per-formed to investigate the loss distribution of heat and exergy for every part of the diesel engine.For the ethanol diesel-oil alterna-tive fuel, the thermal balance and exergic analysis of the diesel engine are carried out also.The results illustrate that, after using ethanol diesel alternative fuel, at the same time keeping fuel exergic and useful work as a constant, the fuel consumption in-creased 3.456%.However, thermal efficiency slightly increases and the carbon dioxide of diesel engine emission is greatly re-duced.
