An internal combustion engine having a combustion chamber divided into two regions by an arcuate barrier on the top of the piston and a complementary arcuate barrier formed in a cavity of the cylinder head. When the piston is at top dead center, the combustion chamber is effectively divided into two portions with approximately ten percent of the chamber being in the vicinity of a fuel injector and a spark plug. By this structure, the engine minimizes the amount of fuel used at idle and at very low power levels, and yet engine performance at higher power levels is not affected.
