International ClassF02B 1/14AbstractThe present invention aims at expanding an operation range for allowing a compression ignition combustion operation. The present invention provides an internal combustion engine of a compression ignition type that is capable of operating with a compression ignition combustion scheme in a given operation range. The ECU of the internal combustion engine detects an operating condition of the internal combustion engine and determines, according to the detected operating condition, which mode is to be used operate the internal combustion engine, a 4-cycle compression ignition mode or a 2-cycle compression ignition mode. The ECU controls the internal compression engine to perform the compression ignition mode determined. According to the present invention, the compression ignition combustion operation is switched from 4-cycle to 2-cycle when the operating condition of the internal combustion engine is in such state that the 4-cycle compression ignition mode cannot be performed, fro example, when the exhaust temperature is low. | |
