Abstract
An internal combustion engine includes an engine block, a combustion cylinder including a cylinder wall, engine oil and engine coolant. Control of the internal combustion engine includes estimating the cylinder wall temperature in a temperature state estimator, comparing the estimated cylinder wall temperature to a predetermined temperature threshold, and circulating the engine coolant in the engine when the estimated cylinder wall temperature exceeds the predetermined temperature threshold.
