对置活塞二冲程柴油机热平衡和余热可用能分析
Analysis of Thermal Balance and Waste Heat Exergy for Opposed-Piston Two-Stroke Diesel Engine
摘要
Abstract
Through the opposed-piston two-stroke diesel full condition bench test,the thermodynamic parameters in each operation condition were determined.The thermal balance was analyzed based on the one law of thermodynamics and compared to the conventional diesel, and the waste heat exergy was analyzed based on the second law of thermodynamics.Results show that: peak of the effective thermal efficiency appears in high-speed and medium-load area;at low-speed and low-load, cooling water accounts for the major part of waste heat energy, and lower than conventional diesel;at high-speed and high-load, exhaust gas energy accounts for the major part of waste heat energy, and higher than conventional diesel.Exhaust gas exergy is larger than cooling water exergy, and the maximum value can reach 67% of exhaust gas energy with great development space.关键词
