ABSTRACT:
The engine is provided with an auxiliary chamber having an auxiliary chamber port with an opening communicated with the combustion chamber. The auxiliary chamber port is arranged to be opened or closed with an auxiliary chamber valve. The timing of closing the auxiliary chamber valve is in between a final stage of compression stroke in which the temperature within the cylinder becomes higher and an initial stage of explosion stroke. On the other hand, the timing of opening the auxiliary chamber valve is in a middle stage of the compression stroke, thereby allowing the mixed fuel cooled in the auxiliary chamber to be replaced with a portion of the mixed fuel in the combustion chamber, thereby lowering the temperature within the cylinder.
