Exhaust-to-Intake Temperature Ratio
Ratio of exhaust-gas to charge-air temperature - a sensitive indicator of cylinder fuel balance, valve timing and cooler performance.
T_exh / T_in (K/K)

Status
Normal
Formula, assumptions, and limits
Uses absolute Kelvin. For slow-speed at MCR expect 2.0–2.3. Two-stroke units with water-side CAC fouling show declining r_T over months as intake T rises.
