Abstract
A combustion chamber of an internal combustion engine has the form of a B-shaped chamber which consists of two spheroidal or spherical contiguous chambers which form an inwardly extending projection against which the air and fuel mixture impinges so as to be divided into two swirl flows which sweep residual burned gases of the previous cycle in the combustion chamber, thereby preventing knocking in the operation of the engine to improve the fuel consumption, driving performance and output of the engine.
