Abstract
A dual fuel common rail engine supplies pressurized natural gas and liquid diesel fuel at different pressures through a co-axial quill assembly for direct injection from a single fuel injector into an engine cylinder. Pressure waves in the gaseous fuel common rail are damped in a pressure damping chamber of the co-axial quill assembly before the pressure wave can undermine consistent gaseous fuel injection rates and quantities from the fuel injector.
