Abstract
Systems and methods for monitoring engine oil temperatures to detect higher than normal oil temperatures are provided. The system comprises a plurality of sensors for obtaining input signals from the operating engine for a predetermined set of engine conditions. At least one of the plurality of sensors includes an oil temperature sensor for measuring an engine oil temperature. The system also includes an engine control unit (ECU) where a plurality of predetermined limit values corresponding to at least one predetermined set of engine operating conditions is stored. The engine control unit is configured to select a predetermined limit value corresponding to a measured set of engine operating conditions, to calculate a maintenance limit value using the selected predetermined limit value, and to compare the measured oil temperature with the maintenance limit value. An output unit outputs a predetermined output depending on the result of the comparison.
