击穿点火——适用于车用汽油机稀薄燃烧的高能点火方式

Puncture Ignition-A Kind of High Energy Ignition System for Weak Mixture Combustion in the Vehicle Gasoline

说明了对于稀薄燃烧来说有效点火能量是决定着火和稀薄燃烧极限的基本因素;介绍了击穿点火方式的基本原理,指出击穿放电阶段能量转换率最大,击穿放电方式的火花功率最大;将申穿点火方式和其它点火方式进行了比较,得出击穿点火是一种值得研究和应用的高能点火方式的结论。

Describing the fact that the effective ignition energy is the basic element determining ignition and combustion lim-iting condition of weak mixture. Introducing the principle of puncture ignition and during the puncture stage the energy transfering is the maximum, and the spark power is also the maximum. Comparing this type of ignition with other types, and drawing a conclusion, that is , this puncture ignition is worthy to be studied and applied on the vehicle.
