Abstract

This paper, we analyzed that the measured data of the radiated power spectrum of electromagnetic waves of the normal spark ignition system and the spark ignition system with feed through type ceramic condenser. The results show that the strength of power spectrum radiated from the system with feed through type ceramic condenser is weaker than the normal system, and the density of power spectrum radiated from the system with feed through type ceramic condenser is smaller than the normal system. From these results, the feed through type ceramic condenser can reduce the electromagnetic waves radiating from the spark ignition system which is the spurious emission, and it can be concluded that the ignition coil of the spark ignition system generating high voltage pulse is equivalent to the radio frequency oscillator which is oscillating high frequency from a electronic point of view.

정상적인 불꽃 점화 시스템과 관통형 세라믹 콘덴서를 부가한 불꽃 점화 시스템에서 복사되는 전자파의 전력 스펙트럼의 측정 데이터를 분석한 결과 관통형 세라믹 콘덴서를 부가한 불꽃 점화 시스템에서 복사되는 전자파는 정상적인 불꽃 점화 시스템에서 복사되는 전자파 보다 약하고, 스펙트럼 밀도 또한 소하였다. 이것은 불꽃 점화 시스템에서 복사되는 불요 전자파를 관통형 세라믹 콘덴서가 감소시키는 것이라고 할 수 있으며, 고압의 펄스를 발생하는 점화 코일은 고주파를 발생하는 무선 주파 발진기라고 할 수 있다.
