預(yù)擊穿階段可以通過(guò)湯森放電理論進(jìn)行解釋，在傳統(tǒng)點(diǎn)火系統(tǒng)中，當(dāng)初級(jí)線圈充電結(jié)束斷開(kāi)初級(jí)線圈回路后，次級(jí)線圈的感應(yīng)電動(dòng)勢(shì)增大，點(diǎn)火電極電極之間的電場(chǎng)逐漸增大，中心電極表面的電子在電場(chǎng)作用下加速并逃逸出來(lái)，以**快的速度奔向側(cè)電極，形成電流并達(dá)到接近飽和的狀態(tài)。隨著電場(chǎng)強(qiáng)度的增加，更多的電子開(kāi)始飛向側(cè)電極，并在電場(chǎng)的作用下獲得足夠的動(dòng)能。在飛行路徑上，加速的電子和氣體原子以一定概率發(fā)生碰撞，并產(chǎn)生新的自由電子，自由電子倍增。被撞擊后的氣體原子由于失去了電子而變成正離子，在電場(chǎng)的作用下飛向陰極撞擊出更多的電子。當(dāng)電子數(shù)量呈幾何倍數(shù)增加并達(dá)到極限時(shí)，原本絕緣的氣體被擊穿，變成等離子態(tài)。
