| Abstract: | Various technologies presented herein relate to heating a fuel and
enhancing fuel and charge-gas mixing inside a combustion chamber to
enable minimal, or no, generation of soot and/or other undesired
emissions during ignition and subsequent combustion of the locally
premixed mixtures. To enable sufficient mixing of the fuel and
charge-gas, a jet of fuel can be directed to pass through a bore of a
duct causing charge-gas to be drawn into the bore creating turbulence to
mix the fuel and the drawn charge-gas. The duct can be heated to
provision heating of the fuel and charge-gas mixture. The duct can be
located proximate to an opening in a tip of a fuel injector. An ignition
assist component can be located downstream of the duct to facilitate
ignition of the fuel/charge-gas mixture. |
