Webengines at altitude. If you see EGTs this high, consider throttling back, and check your turbine inlet temperature (TIT) because it’s probably also too high. • Some engine designs have notoriously high EGT spreads (a.k.a. “lean range” page 47). Fuel injected engines with stock injectors are usually 80-100°F, but the Continental IO-470 ... Webthat CHT inﬂuenced the NOx, soot, and heat release rate predictions, due to CHT being able to predict spatially and temporally varying temperatures. Fontanesi et al.
