Abstract:
Method of regulating the heat of an internal combustion engine by using electrically controlled devices which deliver and regulate volume flow of a cooling medium or heating medium and through the use of temperature sensors at a number of points of the internal combustion engine which generates temperature-dependent signals, which are processed in an electronic evaluation unit wherein said unit includes at least one microprocessor to form actuating signals for a plurality of devices wherein temperatures of the cooling media and/or heating media are registered, said method comprising the steps of;registering at least one of critical component temperatures and characteristic output values of the internal combustion engine; detecting changes in said at least one of the critical component temperatures and the characteristic output values of the internal combustion engine; providing regulation of said heat of the internal combustion engine as a function of said provided changes in said at least one critical component temperatures and said characteristic output values; wherein the step of registering at least one of critical component temperatures and characteristic output values of the internal combustion engine includes the step of registering the temperature of a cylinder head in a region between output valves.
