Abstract
A method of estimating temperature in an engine including estimating metal temperatures at each of a plurality of nodes and estimating a coolant temperature. The method further includes detecting a measured coolant temperature and determining a gain based on a difference between the estimated coolant temperature and the measured coolant temperature. The method adjusts the metal temperatures at each of the plurality of nodes based on the gain. The method estimates the metal temperatures of engine components without temperature sensors.
