INTERNAL COMBUSTION ENGINE, COMBUSTION CHARGE FORMATION SYSTEM, AND METHOD

摘要

A gaseous fuel internal combustion engine (10) includes an engine housing (12) defining at least one cylinder (14), and an intake housing (18) defining an intake passage (20) fluidly connecting with the at least one cylinder (14). The engine (10) includes a gaseous fuel delivery mechanism (13) coupled with the engine housing (12) and a distributed ignition promoting mechanism (22) having a bead presentation device (24) extending into the intake passage (20) and configured to present a liquid bead of distributed ignition promoting material (100) therein such as engine lubricating oil. During operation, gases passing through the intake passage (20) dislodge the liquid bead from the bead presentation device (22) and carry the distributed ignition promoting material (100) into the cylinder (14) for distributively igniting therein a mixture containing a gaseous fuel, air and the distributed ignition promoting material (100).
