Abstract
An internal combustion engine having a main combustion chamber, an auxiliary combustion chamber having inlet and outlet ports through which the auxiliary combustion chamber is communicated with the main combustion chamber, an intake port for supplying a lean air/fuel mixture to the main combustion chamber and an auxiliary passage disposed in the intake port for supplying a rich air/fuel mixture. A cylinder head of the engine has a cylindrical recess connecting with the intake port so as to enable the mixtures to flow through the intake port and the recess into the combustion chambers. An intake valve is adapted to seat, at the closed position, a on value seat disposed at the bottom of the recess. The auxiliary combustion chamber is communicated through the inlet port with the recess so that the rich air/fuel mixture is effectively conducted into the auxiliary combustion chamber through the inlet port when the intake valve is at the partially open position and is still positioned within the residual recess.
