摘要
基于质量守恒原理,构建了柴油机排气流量模型.根据该模型,利用柴油机进气流量测量值,可计算出柴油机排气流量,通过试验数据分析,由排气分析仪实测得出的排气流量值和由本文模型计算得出的排气流量值比较,相对误差在允许范围内,该计算模型在发动机试验中具有实用性.
With the quality of conservation as the foundation,the exhaust flow model of diesel engine is got.Through the formula and the measured intake flow of diesel engine,indirectly exhaust flow is got.Through the analysis of data,between the measured exhaust flow value based on exhaust analyzer and the calculation model data,the relative error is within permitted,therefore the calculation model is practical in engine tests.
