Japanese Patent JP6264882
Kind Code:
B2
Abstract:
A combustion chamber structure for a spark-ignition internal combustion engine includes a combustion chamber, an ignition plug, and a guide portion. The combustion chamber is configured to produce tumble flow that swirls in an axial direction of a cylinder. The ignition plug is disposed in a central portion of an upper wall of the combustion chamber. The guide portion protrudes from the upper wall of the combustion chamber, and is configured to guide airflow passing through the central portion of the combustion chamber in an intake-exhaust direction of the combustion chamber while dispersing the airflow around the guide portion.
