Mine is more like the "Passive MAHLE pre-chamber"

I still use my PFI for fuel delivery. My pre-chamber is designed to collect fuel on the intake and compression stroke and uses my own designed spray guided piston to assist with this collection. The pre-chamber has a rich A/F ratio to promote flame speed by a torch flame kernel and reduce misfire. This allows for the main chamber to run at extreme lean conditions 30:0 plus while still having a low numeric BSFC number. My turbo plays a major part in the design by having high airflow numbers at light load to promote air/fuel to the pre-chamber and increase flame speed.
