涡轮当量面积和增压器效率是增压配机中两个重要参数,它们的相互配合直接关系到柴油机与增压器能量的分配和气缸工作参数。本文通过所建立的(?)_T-(?)_(TK) 图谱探讨了它们之间的关系及其对三种不同类型柴油机性能的影响,分析了不同增压度下增压器效率对油耗的影响。并且还以实际柴油机的运行点作了验证。所作论证对于不同类型不同增压度的柴油机来说.选择适当效率水平的增压器并配以适当的涡轮当量面积以达到良好的经济性具有实际意义。
Turbine equivalent area and turbocharger efficiency are two important parameters in turbocharging. Their mutual cooperation is directly related to the energy distribution of diesel engine and turbocharger and cylinder operating parameters. In this paper, the relationship between them and their influence on the performance of three different types of diesel engines are discussed through the established (?) _T - (?) _ (TK) map. The effects of turbocharger efficiency on fuel consumption Impact. And also with the actual operating point of the diesel engine has been verified. The justification for different types of diesel engines with different intensities of pressurization is of practical significance in choosing a turbocharger with an appropriate level of efficiency and a suitable turbo equivalent area for good economy.
