Zusammenfassung:Provided is a piston temperature state monitoring system for an internal combustion engine and a piston temperature monitoring method for an internal combustion engine which are capable of properly managing a history of a piston temperature. When the number of times of a piston temperature suppression control is counted, if a ratio µ of a temperature difference ΔT which is the difference between a maximum limit temperature Tmax and a piston temperature Tp to a margin width ΔTm which is the difference between the maximum limit temperature Tmax and a control start temperature Tc is equal to or less than a count threshold ratio µc set in advance or calculated, a count output system M13 outputs a count signal Cs.
