摘要： An ignition timing control apparatus for an internal combustion engine capable of using as a fuel a regular (low-octane) gasoline, a premium (high-octane) gasoline, or a mixture of both type of gasolines. The engine produces knocks when the ignition timing is advanced beyond a reference ignition timing determined as a function of the type of gasoline being used. This advance ignition timing control apparatus detects the knocks, and provides as an output a signal according to the occurrence rate of the knocks which essentially indicates the type of gasoline in use. By means of this signal, this ignition timing control apparatus performs two types of controls one of which is to change over one reference ignition timing adapted for the premium gasoline to the other reference ignition timing for the regular gasoline to retard the current ignition timing, and the other of which is to continuously displace the reference ignition timing in the direction of retard angle by using a proportion factor calculator and an interpolator. At the same time, the changed-over reference ignition timing or the displaced reference ignition timing is corrected by the detected knock signals on a real time basis. The combined ignition timing signal serves to energize an ignition coil to suppress the occurrence of knocks. This operation will continue until no knocks occur. Additionally, other operating parameters such as a compression ratio, a supercharging pressure, and air/fuel ratio etc., can also serve to suppress the occurrence of knocks.

摘要翻译：一种用于内燃机的点火正时控制装置，该内燃机能够使用普通（低辛烷值）汽油，高级（高辛烷值）汽油或两种汽油混合物作为燃料。当点火正时提前超过根据正在使用的汽油类型而确定的参考点火正时时，发动机产生爆震。该提前点火正时控制装置检测爆震，并根据基本上表示使用中的汽油类型的爆震发生率提供一个信号作为输出。借助于该信号，该点火正时控制装置执行两种控制，一种是将适用于优质汽油的一个参考点火正时切换到普通汽油的另一参考点火正时，以延迟当前点火正时，并且另一个是通过使用比例因数计算器和内插器在延迟角方向连续地移动参考点火正时。同时，通过检测到的爆震信号实时地校正转换参考点火正时或移动参考点火正时。组合点火正时信号用于激励点火线圈以抑制爆震的发生。该操作将继续进行，直至不发生敲击。另外，压缩比，增压压力，空燃比等其他运转参数也能够抑制爆震的发生。
