On the Application of Passive Pre-chambers to Difficult-to-Ignite Air-Fuel Mixtures in Internal Combustion Engines

Internal combustion engines influence global CO2 emissions. To address this, there is a growing emphasis on alternative fuel-based strategies, notably lean mixtures and using ammonia as a fuel. These pathways offer significant advantages but are limited by their high ignition energy requirements.
