Abstract
An internal combustion engine is controlled during a warm-up period as a function of a cumulative measure of energy supplied to the engine. For example, the total amount of fuel delivered to the engine since start-up or an accumulated value of a load level of each combustion event during the warm-up period may be measured. A degree of offset or modification of individual engine operating parameters during the warm-up period may be based upon the cumulative measure of energy supplied to the engine.
