火花塞热值测定及其点火的波形分析

本文着重通过对火花塞正常点火和炽热点火离子电流显示的波形分析介绍在大量试验中观察到的一些新的现象和其中的内在联系，并对与波形分析密切相关的火花塞热值测定作了必要的介绍，最后还就离子电流作为燃烧现象的讯号在内燃机中的进一步应用作了探讨．

Preignition Rating of Spark Plugs and the Oscillogram Analysis on Its Ignition

In this paper some new phenomena observed in many tests and the internal relations found among them are introduced by the oscillogram analysis on normal ignition and preignition of spark plugs showed by ion current, the preignition rating of spark plugs closely related to the oscillogram analysis is demonstrated essentially, and the further applications of ion current as a signal of combustion in internal combustion engines are discussed.
