ABSTRACT:
A method for enabling a transition of a multiple-displacement engine to a different engine operating displacement includes determining a temperature measure correlated with an instantaneous engine oil temperature at an engine start-up, for example, a detected engine coolant temperature at engine start-up; determining a start-up delay period based on the temperature measure, as with a lookup table of calibratable values; and enabling a displacement mode transition no earlier than when the engine run time since start-up exceeds the start-up delay period.
