1·Knock the eternal alive the spark of love.

撞出永久不熄的爱的火花。

2·Researches on knock combustion in BJ492Q using spark plug optical sensors are presented in this paper. The effects of knock intensity on light emission are studied.

应用火花塞光纤传感测量系统对BJ 492 Q汽油机爆燃燃烧进行测量和研究，分析了爆燃燃烧时火焰光辐射的变化情况。

3·When worked in non-knock conditions, the most optimum spark angle is the adder of the initial spark angle, the basic ignition angle and the amendment spark angle.

发动机在非爆震区域工况下，其最佳点火提前角为初始点火提前角、基本点火提前角和修正点火提前角之和。

4·In knock regions, the most optimum spark Angle is the adder of the basic spark Angle, the knock amendment Angle and other amendments.

爆震区最佳点火提前角为基本点火提前角、爆震修正和其他修正之和。

5·The use of the spark plug sensor is proved to be feasible in knock combustion detection.

试验表明，火花塞光纤传感器完全可用于爆燃测量。
