柴油机冷起动辅助措施的匹配优化试验研究

Research on the Matching Optimization Experiment for Support Measure of Cold Start of Diesel Engine

重点论述了柴油机冷启动辅助装置燃油加热器的选型试验。对燃油加热器优劣的评价指标进行了分析研究,提出了燃油加热器的评价方法。最后通过样本CFD分析,优化了燃油加热器与发动机之间水路系统的匹配,实际效果进行了试验验证。

This paper mainly discusses engine start assistant statement. With disadvantage evaluation specification the selection experiments for diesel heater with diesel the analysis and research for diesel heater＇s advantage and the diesel heater selection evaluation method is proposed. Finally, through the analysis of CFD sample, matching between diesel heater and engine water flow system is improved, and the actual effect is tested and verified.
