Embodiment 600

[0048] Embodiment 600 may be similar to embodiment 500, except that embodiment 600 is a multi-hole injector configured to inject multiple fuel injections 622 and Figure 5 The Example 500 is other than a single hole injector. Accordingly, embodiment 600 may receive dilution gas from each of adjacent cylinders via high pressure dilution gas line 442 or via receiving dilution gas from reservoir 234 .

[0049] now refer to Figure 7 , which shows a non-limiting example embodiment 700 of fuel injector 66 . Embodiment 700 is similar to embodiment 600 except that embodiment 700 receives dilution gas only from adjacent cylinders via high pressure dilution gas line 442 . Accordingly, embodiment 700 does not receive dilution gas from reservoir 234 .

[0050] now refer to Figure 8 , which shows a non-limiting example embodiment 800 of fuel injector 66 . Embodiment 800 is similar to embodiment 600, except that embodiment 800 receives dilution gas only from reservoir 234 and does no...

Abstract

The invention provides methods and systems for a ducted injector. Methods and systems are provided for a ducted fuel injector. In one example, the ducted fuel injector comprises a plurality of passages, with at least one of the passages configured to receive an oxygen poor gas from a reservoir or an adjacent cylinder to decrease a likelihood of pre-ignition in the duct.

Description

technical field [0001] This specification generally relates to a ducted fuel injector. Background technique [0002] In a diesel engine, air is drawn into the combustion chamber during the intake stroke by opening one or more intake valves. Then, during the subsequent compression stroke, the intake valve closes, and the reciprocating piston of the combustion chamber compresses the gases that entered during the intake stroke, raising the temperature of the gases in the combustion chamber. Fuel is then injected into the hot compressed gas mixture in the combustion chamber, causing combustion of the fuel. Therefore, in a diesel engine, due to the high temperature of the air, the fuel may burn with the air in the combustion chamber and may not ignite via the spark plug as in a gasoline engine. The combusted air-fuel mixture pushes the piston, which drives the piston motion, which is then converted into rotational energy of the crankshaft. [0003] However, the inventors have ...
