摘要：
A system includes an input and a thermal data processing module. The input receives a first oil temperature of an engine oil when an engine is turned on. The thermal data processing module estimates a first heat transfer from a piston of the engine to the engine oil. The thermal data processing module estimates a second heat transfer from the engine oil to an engine block of the engine. The thermal data processing module determines a second oil temperature of the engine oil based on the first oil temperature and the first and second heat transfers.
