Study on the Optimal Pre-Chamber Geometry for Active Pre-Chamber Gas Engines
SAE Technical Paper Series<div class="section abstract"><div class="htmlview paragraph">In a pre-chamber engine, fuel in the main-chamber is ignited and combusted by the combustion gas injected from the pre-chamber. Therefore, further fuel dilution is possible and thermal efficiency can be also improved.

Influence of Internal Geometry on Pre-chamber Combustion Concept in a Lean Burn Natural Gas Engine
2022The road transport sector, dominated by internal combustion engines, accounts for as high as 23% of annual carbon emissions and is considered the major area where urgent carbon reduction strategies are required. Natural gas is considered one of the intermediate fuels to reduce carbon emissions before net carbon neutral solutions can be achieved ...

A systematic experimental and numerical investigation on the effects of chamber geometry and fuel–air mixture conditions on flame propagation and subsequent turbulent jet formation in a pre-chamber ignition system is conducted. Investigation of initial pre-chamber pressure showed that higher pre-chamber pressure led to slower flame propagation ...
