An internal combustion engine including a cylinder having an inner cylinder wall, a piston having a crown received in the cylinder, and a cylinder head coupled to the cylinder. The cylinder head defines an intake port and an exhaust port. The piston is configured to reciprocate between a top dead center position and a bottom dead center position. Wherein when the piston is in the top dead center position, the inner cylinder wall includes an exposed portion above the crown. A combustion chamber is defined between crown of the piston, the exposed portion of the inner cylinder wall, and an inner surface of the cylinder head. The exposed portion of the inner cylinder wall includes a series of surface features to promote mixing of an air-fuel mixture in the combustion chamber. |
