Nlde-3 Engine Manual [better] -

Most IDI engines use a simple pre-chamber nozzle. The NLDE-3 uses a inside a tangential-entry pre-chamber. CFD simulations (retrospectively run in 2023) show that the V-tip creates a double vortex, improving air-fuel mixing by ~12% compared to straight-tip designs—but only if the pre-chamber carbon gap is kept under 0.3 mm. The manual stresses cleaning this gap with a 5.2 mm reamer, not a drill bit (a common error destroying the chamber).
