The knock threshold detection is the key of gasoline engine knock detection, and it is the key of the closed loop ignition control of gasoline engines.

汽油机爆震的难点是爆震边缘点检测，爆震边缘点是汽油机点火闭环控制的前提。

The engine electronics system also controls the ion stream knock control that gauges the ideal ignition time of the individual cylinders, thus making full use of the engine's potential.

引擎电子系统还控制着离子流冲撞控制，准确估计出每缸的理想点火时间，从而将引擎的潜在能力充分发挥出来。

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。
