Internal Combustion Engine Partitioning Wall Through Holes

The through holes are arranged asymmetrically with respect to the radial direction. Specifically, the through holes are positioned at different angular positions and/or have different orientations compared to a purely radial arrangement, creating an asymmetric flow pattern that prevents flow attenuation while maintaining manufacturing simplicity.

The through holes are oriented in multiple directions rather than purely radially. By introducing angular variation in the hole orientations, the design transitions from a one-dimensional radial pattern to a multi-dimensional arrangement, allowing air-fuel mixture to flow into the ignition chamber from multiple angles, thereby preventing flow attenuation and improving ignition reliability.

The asymmetric arrangement of through holes prevents the formation of opposing velocity components that would otherwise attenuate the air flow. By positioning holes at non-radial angles, the incoming air-fuel mixture flows smoothly into the ignition chamber without encountering counter-directional flow, maintaining high flow rates while still enabling effective flame ejection to the main combustion chamber.

The optimized angular arrangement of through holes creates a more uniform, rounded flow pattern into the ignition chamber. This curved flow distribution, achieved by strategically positioning holes at various angles, eliminates sharp velocity reversals and promotes smooth, continuous flow, thereby maintaining high air flow rates while ensuring proper flame propagation.
