摘要： A control device for cylinder injection type spark-ignition internal combustion engines which includes a fuel injection valve (4) for injecting a fuel directly into a combustion chamber (5) such that when an internal combustion engine (1) is run within a predetermined running region, the fuel is injected mainly during a compression stroke to effect stratified-charge combustion. A target load value Pe set according to an accelerator opening information at least based on a driver's operation is corrected with an environmental parameter detection value correlated with an intake density, engine control parameter values Tend, Tig are set on the basis of the corrected target load value Pec, and stratified-charge combustion is carried out on the basis of the engine control parameter values. Accordingly, stratified-charge combustion is performed stably with certainty even if environmental parameter values, such as an atmospheric pressure and intake temperature, correlated with the intake density differs largely from those of the standard atmospheric pressure at the time of engine running in highlands and the like.

摘要： A controller of an in-cylinder spark ignition internal combustion engine switches a control mode in accordance with the engine operating condition between a compression stroke injection mode control under which the fuel is injected during a compression stroke and laminar combustion is effected and an intake stroke injection mode control under which the fuel is injected during an intake stroke and uniform mixing and combustion are effected. When a regular gasoline having a lower octane value than that of a premium gasoline is used, the octane value of a target mean effective pressure (Pe) set in accordance with the throttle opening ( theta th) is corrected so that the engine output before and after the mode switching is compensated so as to thereby prevent a torque shock at the time of mode switching.
