离子电流法在直管道燃烧器中应用的初步研究

Study on Application of Ionic Current in Straight Conduit Combustion Bomb

在一种新型直管道燃烧器中用离子电流法,对预混天然气进行燃烧基础特性的测试。通过控制温度和空燃比两个参数变化,进行单参数调节,分析了偏置电压变化与离子电流信号的关系,消除了由于发动机循环变动对燃烧状态和离子电流强度的不稳定影响。试验结果为离子电流法在发动机上的应用提供了基础性研究。

The basic characteristics of natural gas during combustion are studied by measuring ionic current in a straight conduit combustion bomb, which can control the change of temperature and A/F to avoid the unstable state of combustion and ionic current resulted from the cyclic variation in the engine experiment. This experiment studies the relation between ionic current and bias voltage in different conditions with a single parameter changed. The results provide for the application of ionic current in engine with.
