摘要
摘要本文研究了点燃式发动机点火能量对火核生成和初期发展的影响.发现增加点火时的击穿能量,可使火核的初始尺寸有效地增加,从而加快火焰的形成和初期发展,并且可以燃烧更为稀薄的混合气,而仅仅增加电容和电感放电阶段的点火能量却没有显著的效果.
Effects of spark energy on the flame initiation and early development in a spark ignition engine was studied. It was discovered that augmentation of breakdown energy in spark duration increased initial flame size effectively, resulted in speeding up flame kernel formation and early development, and promoting lean mixture combustion. But, the increase of spark energy only during the period of capacitive and inductive discharge had no obvious effect.
