In the combustion chamber structure, an ignition plug is disposed in the combustion chamber at a position on the downstream side with respect to the intake swirl, and a squish flow is guided into the squish zone in a direction opposite to the intake swirl to stimulate the combustion. A combustion chamber structure for an engine characterized by having a guide channel for feeding fuel into the combustion chamber.
