Abstract
A particular engine control system is used with an engine equipped with an automatic transmission. The automatic transmission is changeable between an economy operation mode, in which the automatic transmission is placed more frequently in higher gears so as to create a travel mode giving priority to fuel economy, and a power operation mode, in which the automatic transmission is placed more frequently in lower gears so as to create a travel mode giving priority to powerful running. The system controls the engine so as to provide a gentle increase in engine output in the economy mode.
