Determining the oil temp. for internal combustion engine enables highly accurate measurement of oil temp. without using oil temp. sensor |
摘要 |
The method involves measuring the temperature of the coolant and deriving the oil temperature iteratively from the coolant temperature and the coolant temperature gradient if the coolant temperature is below a threshold or from a load parameter and the revolution rate if the coolant temperature is above the threshold.
