  • Patent number: 9926823
    Abstract: A method for controlling an exhaust after-treatment system connected to a diesel engine via a gas passage and having a diesel oxidation catalyst (DOC) and a “diesel-exhaust-fluid” (DEF) injector arranged downstream of the DOC and upstream of a selective catalytic reduction catalyst (SCR) includes detecting a flow of exhaust gas emitted by the engine into the gas passage. The method also includes detecting a level of nitrogen oxides (NOx) in the exhaust gas downstream of the SCR. The method additionally includes activating the DEF injector for a period of time to reduce the level of NOx to a predetermined NOx value. Furthermore, the method includes regulating an injection of fuel upstream of the DOC to clean the DEF injector via a stream of superheated exhaust gas if the period of time used to reduce the level of NOx to the predetermined NOx value is greater than a predetermined threshold value.

  • Patent number: 8434457
    Abstract: Various fuel injection systems and fuel injectors are disclosed that provide varying cooling rates for fuel injectors connected in series to fuel supply and drain rail. The local cooling rate for each injector is manipulated to balance the heat flux or heat transfer across the injectors disposed along the rail. The cooling rates may be manipulated by varying sizes of openings or slots in the nozzle case, by varying annular spaces disposed between the nozzle case and the portion of the injector body that houses the actuator and solenoid assembly, and by varying the size of annular spaces disposed between the nozzle case and the cylinder head. Strategic placement of slots in the nozzle case that direct more flow at the portion of the injector body that houses the actuator and solenoid assembly may also be employed. As a result, the operating temperatures of fuel injectors connected in series to a fuel rail can be manipulated and moderated so the downstream injectors are not prone to overheating.

  • Patent number: 8201754
    Abstract: A common rail single fluid injection system includes fuel injectors and control valve assemblies with an internal cooling fluid circuit to improve overall life and performance of the injector. This is accomplished by supplying cooling fluid to the injector and allowing the same to come in direct contact with one of the hottest locations within the fuel injector; the high-pressure leak split spot. By providing cooling fluid directly to this location and then allowing the cooling fluid to drain out of the injector, the present disclosure effectively and efficiently manages thermal loads within the injector.

  • Publication number: 20110315118
    Abstract: Various fuel injection systems and fuel injectors are disclosed that provide varying cooling rates for fuel injectors connected in series to fuel supply and drain rail. The local cooling rate for each injector is manipulated to balance the heat flux or heat transfer across the injectors disposed along the rail. The cooling rates may be manipulated by varying sizes of openings or slots in the nozzle case, by varying annular spaces disposed between the nozzle case and the portion of the injector body that houses the actuator and solenoid assembly, and by varying the size of annular spaces disposed between the nozzle case and the cylinder head. Strategic placement of slots in the nozzle case that direct more flow at the portion of the injector body that houses the actuator and solenoid assembly may also be employed. As a result, the operating temperatures of fuel injectors connected in series to a fuel rail can be manipulated and moderated so the downstream injectors are not prone to overheating.
