Cylinder injection type internal combustion engine and combustion control method at starting thereof

摘要

A cylinder injection type internal combustion engine (1) includes a fuel injection valve (10, 160, 170) for directly injecting a fuel into a cylinder and a catalyst (13a, 13b) for cleaning up an exhaust in an exhaust gas and has at least two combustion control patterns for activating rapidly the catalyst (13a, 13b). The combustion control patterns are switched over based on a temperature of the catalyst (13a, 13b). Furthermore, a stratified combustion is provided at the time of starting by making a configuration of the combustion engine (1) optimum. <IMAGE>
