摘要： Often NOx selective catalysts that use ammonia to reduce NOx within exhaust to a harmless gas require on-board storage of ammonia which can be hazardous and inconvenient. In order to generate ammonia in exhaust, the present disclosure increases a NOx concentration in exhaust from at least one combustion chamber, at least in part, by injecting fuel in a predetermined increased NOx generation sequence that includes a first injection during non-auto ignition conditions and a second injection during auto ignition conditions. At least a portion of the NOx is converted to ammonia by passing at least a portion of the exhaust with the increased NOx concentration over an ammonia-producing catalyst.

摘要： A method of retrofitting an engine with an exhaust system is disclosed. The method may include placing an exhaust treatment device in an exhaust duct of the engine, and placing an exhaust heater in fluid communication with the exhaust duct of the engine at a location upstream of the exhaust treatment device.

摘要： A method of operating an engine system should produce relatively low concentrations of various emissions without compromising a desired power output of the system. In order to operate an engine system of the present disclosure, a predetermined total amount of fuel injected into at least one combustion chamber is apportioned into at least a first amount and a second amount of fuel. The first amount of fuel is injected into the at least one combustion chamber during non-auto ignition conditions. The second amount of fuel is injected into the at least one combustion chamber during auto-ignition conditions. When the engine system is in a mid-low engine load range, the second amount of fuel is one of equal to or less than 15% of the predetermined total amount of fuel. When the engine system is in a high engine load range, the second amount of fuel is greater than 15% of the predetermined total amount of fuel.

摘要： In one aspect, a common rail fuel system includes a plurality of fuel injectors that each include an injector body defining a first fuel inlet fluidly connected to a first common rail and a second fuel inlet fluidly connected to a second common rail. Liquid fuel injection from a first nozzle outlet set is facilitated by energizing a first electrical actuator to open a direct operated check. Injection of gaseous fuel from a second nozzle outlet set is facilitated by energizing a second electrical actuator to open an admission valve to flood a gaseous nozzle chamber with high pressure gaseous fuel above a valve opening pressure that opens a conventional spring biased check to facilitate gaseous fuel injection out of second nozzle outlet set.
