Abstract
Knowledge learned through the successful application of millions of knock sensors on automotive engines is reported. An explanation of the basic characteristics of the knock phenomena and their relationship to sensing capabilities is given. Popular conceptions and misconceptions concerned with engine knock and the variables affecting it are examined. Sensing methods are described, with the emphasis being on vibration sensitive devices. Application methodologies and issues are discussed, with a review of potential pitfalls in sensor selection, sensor location, and systemization.
