车用焦炉气特性及理化参数计算模型研究

Research on Characteristics and Calculation Model of Physicalchemical Parameters of Coke Oven Gas for Vehicles

对焦炉气理化参数的确定建立了计算模型,通过模型计算得出焦炉气的化学计量空燃比、比热容、等熵指数、热值、黏度等参数值,为发动机的结构改进设计与优化提供了参考。最后对燃料热值及等熵指数等参数进行了分析,得出焦炉气的热值较高,发动机直接使用焦炉气作燃料可获得良好的综合性能。

Establish calculation model for several physic-chemical parameters, such as chemical on me-tering fuel-air ratio, specific heat capacity, isentropic exponent, calorific value act., which provides a refer-ence for the design and optimization of the structure of the engine. Finally, the calorific value of the coke oven gas and the isentropic index data were analyzed. Results show that the coke oven gas has high heat-ing value and engine directly using coke oven gas as fuel could obtain good comprehensive properties.
