Ducted fuel injection with ignition assist
| DWPI Title: Fuel injection system for the diesel engine, comprises a fuel injector that is provided with the opening injecting the fuel into a combustion chamber, where duct is formed with a hollow tube aligned with the opening of fuel injector |
| Abstract: Various technologies presented herein relate to enhancing mixing inside a combustion chamber to form one or more locally premixed mixtures comprising fuel and charge-gas 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 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. |
| Use: Fuel injection system for the diesel engine. |
| Advantage: The fuel injection system comprises a fuel injector that is provided with a first opening injecting the fuel into a combustion chamber, where the rod is connected to the discharge end of the duct coated with the catalytic material, and hence prevents the undesirable emissions in the combustion chamber during the ignition. |
| Novelty: The fuel injection system comprises a fuel injector that is provided with an opening (146) injecting the fuel into a combustion chamber (105). A duct is formed with a hollow tube aligned with the opening of the fuel injector. An ignition assist component is located at a discharge end of the duct, and ignite the fuel using a catalytic material. A rod is connected to the discharge end of the duct coated with the catalytic material. |
