Abstract

PURPOSE: To raise combustibility of intake mixed gas by ignition by forming a strong swirl flow within combustion chamber in a low load region for an internal combustion engine of a lean-burn or exhaust recycling type.
CONSTITUTION: When engine is in a low load region, the port valve 10 rotates in the closewise direction, its lower end edge 10' touches on the inside bottom 5' of the intake port 5, and intake mixed gas flows biasedly along the ceiling surface 5" of the intake port 5. On the other hand, the upper end edge 10" of the port valve 10 comes near the ceiling surface 5" of the intake port 5 according to the low load of engine, so that the flow of mixed gas along the ceiling surface 5" is gradually faster. And the flow of the mixed gas is introduced into the combustion chamber 4 along the outside surface 8 in a curvi-radial direction of the intake port 5 and also the circumferential wall surface 7 smoothly following the outside surface 8. In consequence, residual gas near the ignition plug 9 is blown off and at the same time a strong swirl flow is produced.
