Prechamber ignition jet geometry: BayerRecent Research Landscape

Incomplete combustion and knock limits in high-compression engines reduce thermal efficiency. This architecture controls the ignition energy distribution through secondary-connected coils and pre-chamber geometry to ensure stable lean-burn performance.

What technical problems is Bayer addressing in Prechamber ignition jet geometry?

Inadequate lean mixture ignition

(2)evidences

Insufficient thermal energy transfer from the prechamber to the main combustion chamber prevents reliable lean-burn initiation. Consistent ignition across varying engine loads ensures stable combustion and reduced cycle-to-cycle variability.

Inadequate main chamber ignition energy

(1)evidences

Slow or inconsistent combustion initiation in lean-burn environments leads to cycle-to-cycle variability. Enhancing the penetration and distribution of ignition energy ensures stable combustion and higher thermal efficiency.
