Looking into the Prechamber of a Lean-Burn Gas Engine.

open access: yesJSME International Journal Series B, 1997
Quartz prechamber models have been installed in a constant volume test rig (CVR) for the investigation of prechamber mixing processes. Planar laser induced fluorescence of acetone has been used for a 2-dimensional visualization of flow structure and quantitative analysis of mixture formation.

Possible applications of prechambers in hydrogen internal combustion engines

open access: yesCombustion Engines, 2022
The use of hydrogen as a fuel for an internal combustion engines has caused many problems for years, the most significant of which seems to be the excessive emission of nitrogen oxides and the tendency to knock combustion. In order to ensure better control of the combustion process in a internal combustion engine powered by hydrogen, it has been ...

Platinum‐Decorated Laser‐Induced Graphene Electrodes: Optimizing Hydrogen Evolution Reaction Catalysis through Minimal Platinum Loading

open access: yesChemNanoMat, Volume 12, Issue 1, January 2026.
Laser‐induced graphene electrodes decorated with platinum (Pt) nanoclusters are engineered via magnetron sputtering to optimize hydrogen evolution reaction (HER) catalysis. By tuning Pt deposition time, a minimal Pt loading (60 s) delivers outstanding HER performance, balancing defect density and Pt2+ anchoring for superior mass activity.
