AI Technical Summary
Technical Problem
Internal combustion engines face inefficiencies due to reduced air flow cross sections caused by the positioning of spark plugs between outlet channels, which limits performance and increases fuel consumption, and conventional machining methods to improve flow are either costly or ineffective.
Method used
A cylindrical recess is created in each outlet channel on the side facing the spark plug, allowing for a larger flow cross section through one-dimensional mechanical processing, mimicking the flow optimization of 5-axis machining at a significantly lower cost.
Benefits of technology
This design achieves 90% of the flow efficiency of 5-axis machining while being cost-effective, resulting in a more efficient and low-fuel consumption operation of the internal combustion engine.

Abstract
The invention relates to an internal combustion engine (10) for a motor vehicle, with at least one combustion chamber (12), and with at least one cylinder head (18) which has at least one combustion chamber roof (16) which partially delimits the combustion chamber (12) and is assigned two exhaust ports (20) of the cylinder head (18) and a spark plug (28) which is held on the cylinder head (18) and is arranged at least partially between the exhaust ports (20), wherein one cylindrical recess (32) is provided per exhaust port (20) in the respective exhaust port (20) on a respective side (S), facing the spark plug (28), of the respective exhaust port (20).
