DESIGN OF COMBUSTION CHAMBER OF INTERNAL COMBUSTION ENGINE WITH SPARK IGNITION Russian patent published in 2017 - IPC F02B23/10 F02F1/24 

FIELD: engine devices and pumps.

SUBSTANCE: design of the combustion chamber of a spark-ignition internal combustion engine includes a combustion chamber, a spark plug and a guide portion. The combustion chamber is configured to reproduce a mixed flow that swirls in the axial direction of the cylinder. The spark plug is located in the central part of the top wall of the combustion chamber. The guide portion protrudes from the upper wall of the combustion chamber and is configured to direct an air flow passing through the central portion of the combustion chamber toward the inlet/outlet of the combustion chamber, allowing air to be separated around the guide portion.

EFFECT: increased efficiency of ignition and combustion of air-fuel mixture.
