Knock suppressing apparatus for internal combustion engine

摘要: A knock suppressing apparatus for an internal combustion engine includes: a sensor sensing the vibrations of and generating corresponding output signal; interface circuit vibration level based on signal sensor; noise detector level; memory storing basic level, threshold correction value in relation to number revolutions per minute engine; calculator updating current operating condition, corrected determination updated value; determiner making comparison between if exceeds threshold; controller controlling, from determiner, control parameter direction suppress knocking. condition may be further provided determining whether is predetermined range suitable value. In this case, updates generates range.
