进气预热对共轨柴油机低温起动的影响研究

Research on the Influence of Intake Preheating on Low-temperature Starting of Common Rail Diesel

主要就进气预热对柴油机的低温起动的影响进行试验研究,通过理论计算、预热参数设计、试验测试等,满足某系列共轨柴油机-25℃下的低温起动要求。

This paper mainly makes experimental research on the effect of intake air preheating on low temperature starting of diesel engines.Through theoretical calculations,pre-heating parameter design,experimental tests,etc.,it is proved to meet the requirements of a series of common rail diesel engines at low temperature starting at-25℃.
