ABSTRACT:
A fuel injection internal combustion engine is provided with a sub-combustion chamber in communication with a main combustion chamber. A volumetric ratio of the sub-combustion chamber to the main combustion chamber is set within a range of 2:8 to 6:4. A mixture switching valve is provided for injecting the mixture of the fuel and compressed air into the sub-combustion chamber, and a spark plug is arranged in the sub-combustion chamber. The sub-combustion chamber is formed of a material having a thermal conductivity which is lower than that of the material forming the main combustion chamber. The mixture switching valve is a mixture gas injection device including a pressure accumulating chamber adjacent to the sub-combustion chamber and to which pressure air is filled, an opening or closing valve to cause the pressure accumulating chamber to be communicated with the sub-combustion chamber in such a way that they may be opened or closed, and a fuel injecting valve for injecting fuel into the pressure accumulating chamber.
