The passage is normally closed by a valve which opens in response to an opening pressure having a predetermined magnitude intermediate the magnitude of the normal combustion pressure and the pressure at which detonation occurs. The passage and the valve may be carried by either the permanent portion of the engine or a replaceable portion, such as a spark plug.
