Effect of Temperature Conditions on Flame Evolutions of Turbulent Jet Ignition
Energies, 2021 Turbulent jet ignition technology can significantly improve lean combustion stability and suppress engine knocking. However, the narrow jet channel between the pre-chamber and the main chamber leads to some difficulties in heat exchange, which ...
