微机采集系统在柴油机冷起动过程研究中的应用

APPLICATIONS OF THE MICROCOMPUTER COLLECTING SYSTEM ON STUDY OF THE COLD STARTING PROCESS IN DIESEL ENGINE

介绍用于内燃机非稳态燃烧过程研究的一种试验数据采集与处理系统。根据内燃机非稳态燃烧过程的特点,提出了非稳态燃烧过程的处理方式。并利用该系统对有起动孔的涡流室式柴油机冷起动过程进行了研究,发现了三种不同形式的主、副压差图及其变化规律。

This paper introduces a system about collecting and handling the experimental data onstudy of the unsteady conbustion in internal combustion engine. A handling way of the un-steady combustion is established according to the characteristics of the unsteady combustionin internal combustion engine. This system is used for studying the cold starting process inswirl chamber diesel engine with start hole. The different pressure diagrams in main andsecondary chambers and their variable laws are found.
