Engine control system for controlling in-cylinder fuel injection engine

An engine control system for controlling an in-cylinder fuel injection engine having compression ignition mode, comprising

• an igniting trigger, and means for adding said igniting trigger by controlling said igniting trigger after a first fuel injection for controlling an initial combustion speed and thereafter performing
• a second fuel injection for torque control, wherein said system is configured such that
• compression igniting of said engine is performed while said engine is operated in a state of low speed and low load and spark ignition burning of said engine is performed while said engine is operated in a state of high speed and high load.

An engine control system for controlling an in-cylinder fuel injection engine having compression ignition mode, comprising

• an igniting trigger supplying means for controlling said igniting trigger so as to supply said igniting trigger after performing a first fuel injection for controlling initial combustion speed, wherein the system is configured such that a condition to generate a radical-flame is adjusted by controlling a state of said igniting trigger according to a driving state of said engine and, after forming said radical-flame, fuel for controlling a torque is injected according to a requested engine torque.
