It's especially critical when cylinders are above 400F. The time when this stress is worst is going from climb power or full power all the way to idle.

WebOct 11, 2005 · The short answer is that your maximum head temperature (away from the cooling coils) would be 500 degrees max (probably). Barrel temperatures would be about 100 degrees less. Exhaust temperatures would be less than 600F. So you can figure that fin temperatures are at least 100 degreees below the temp of the average head … A Cylinder Head Temperature gauge (CHT) measures the cylinder head temperature of an engine. Commonly used on air-cooled engines, the head temperature gauge displays the work that the engine is performing more quickly than an oil or water temperature gauge. As the engine works at high speed or uphill, head temperature will increase quickly. The meter can be digital or analog. graham hutchinson twitter

WebSep 20, 2024 · Cylinder head temperature mainly reflects what is going on during the engine’s power stroke before the exhaust valve opens. It is a measurement of heat energy during the power stroke when the cylinder is under maximum stress from high internal pressures and temperatures. High CHTs indicate the engine is under excessive stress. WebOct 1, 2024 · Lycoming cylinders are built to take this additional heat, with a more robust head-to-barrel junction. This is reflected in Lycoming’s higher redline CHT of 500 degrees F compared with Continental’s redline of 460 degrees F. It’s important to understand that these CHT redlines should be treated as emergency values only. WebJan 8, 2013 · The maximum allowed cylinder head temperature for your engine is 500° F, but for maximum service life I’d like to see between 385° and 400° or a little higher for continuous operation. This is why it is so important to know your instrumentation accuracy and justifies having the instrumentation calibrated from time to time. graham hutton twitter
