WebMar 1, 2024 · This is the best way to propel lean, just because we can see a live view of everything that is happening in the engine. With good equipment, you will have Exhaust Gas Temperature (EGT), Cylinder Head Temperature (CHT), and sometimes oil temperature. On the advanced avionics, you will have a lean assist, and here is how most work. WebCHT measures heat energy wasted during the power stroke, when the cylinder is under maximum stress from high internal pressures and temperatures. EGT measures heat energy wasted during the exhaust …

WebFeb 7, 2011 · EGT is primarily a function of your manifold pressure, RPM, and mixture setting. CHT is a function of those, but also of cooling. As the cooling over your engine is variable dependent on a number of factors (altitude, airspeed, outside air temperature, cowl flap setting, etc.). Lycoming Service Instruction 1094D provides a bit more information ... WebFeb 10, 2024 · CHT is cylinder head temperature, which has more to do with the timing of the spark. Detonation is caused by fuel essentially exploding or burning unevenly in the compression stroke. EGT is lower because ignition of fuel is completed earlier in the cycle, transferring more heat to the cylinder head. port saint lucie school board jobs
