【摘要】 探讨了应用价值工程基本原理对燃用不同掺烧比的乙醇柴油混合燃料发动机的动力性、经济性和排放特性进行综合评价的方法.探讨了按价值系数高低来定量评价掺烧比方案的价值,即性价比高低的评价方法.结果表明针对DL190-12柴油机,乙醇掺烧比为15%的方案是性价比最高的方案.更多还原

【Abstract】 This paper applied the basic principles of value engineering to integrally analyze the dynamic,economic and emission characteristics of engines supplied with ethanol-diesel blend fuel with different blended ratio of ethanol-diesel.It proposed an evaluation method for blended ratio of ethanol-diesel according to value coefficient which reflected the performance-value ratio.Evaluation results indicate that 15% blended ratio of ethanol-diesel is best for ratio of performance-value.更多还原
