WebInconsistent high CHT readings have been a problem in the past. Years ago CHT’s were measured under the spark plug. These measurements were 25 to 50 degrees hotter than CHT well measurements (see appendix A). The cylinder head wall at the spark plug is not thick enough to stabilize the heat conducted by the plug and the top of the cylinder head. WebCHT is our best proxy for internal cylinder pressure (ICP). If we want to protect our engines against excessive ICP, we need to limit CHT to a reasonable value. Whats’ reasonable …
