Abstract
An internal combustion engine 1 at a standstill of a vehicle after cold starting can switch its combustion mode to a homogenous combustion mode or a stratified combustion mode. An operation range of the stratified combustion at the standstill of the vehicle after cold starting is expanded relative to an operation range of the homogenous combustion at the standstill of the vehicle after cold starting as an inclination of the vehicle decreases. With this technique, the operation range of the stratified combustion can be expanded while assuring an intake air negative pressure required for achieving the brake performance, so that HC reduction at the standstill of the vehicle after cold starting is obtained.
