Abstract: A rotary device is coupled to the rotary mechanism of a turbocharger for selectively adding torque to and subtracting torque from the rotary turbocharger mechanism. A controller causes the rotary device to apply torque to the rotary turbocharger mechanism which causes the compressor to operate at a power level which creates a target pressure in the intake manifold different from existing pressure in the intake manifold.

Abstract: A method for controlling operation of an internal combustion engine determines an estimated NOx value as a function of at least one engine operating parameter. The method also determines an actual NOx value using a NOx sensor positioned in an exhaust gas stream of the internal combustion engine. The method detects at least one condition indicative of whether or not the actual NOx value is accurate. The actual NOx value is used for controlling engine operation when the at least one condition indicates that the actual NOx value is accurate, while the estimated NOx value is used for controlling engine operation when the at least one condition indicates that the actual NOx value is inaccurate.

Abstract: A dual-mode fuel injector has an internal part containing a variable volume chamber space which fills with fuel at common rail pressure and a plunger which is operable to force fuel out of the variable volume chamber space and to be injected out of the nozzle through the injection orifices at amplified pressure greater than common rail pressure. The plunger and the internal part have respective surfaces which come into mutual abutment during filling of the variable volume chamber space with fuel at common rail pressure and which, when in mutual abutment, create a seal which seals fuel in the variable volume chamber space against escape from the variable volume chamber space past the seal.

Abstract: A system and method for heating main unit containing host salt having ammonia that is used as reductant in an engine exhaust gas after-treatment system. Engine coolant is delivered from internal combustion engine to auxiliary heating device. When necessary, the auxiliary heating device heats the engine coolant to temperatures that will aid in releasing ammonia from the host salt. The auxiliary heating device may employ an electric heating element, a combustion element, or be an exhaust gas heat exchanger, among other heating methods. The heated engine coolant is delivered to a coolant heating manifold, where heat from the heated coolant is transferred to the main unit. The transferred heat may aid in elevating the temperature in/of the main unit to facilitate the release of stored ammonia from the host salt as a gaseous reductant. The gaseous ammonia may then flow from the main unit.

Abstract: A fuel injector assembly has a control valve body and a plurality of end caps. End cap locating holes are formed into a mating surface of each end cap, and control valve body locating holes are formed into each mating surface of the control valve body. Locating pins inserted into the end cap and control valve body locating holes each have a fixed portion that affixes the locating pins to either the control valve body or the end cap. In the event of failure of a locating pin between the fixed portion and a free portion of the pins, the free portion maintains alignment of the control valve body locating holes with the end cap locating holes.

Abstract: A system for estimation of exhaust gas temperature for internal combustion engine at low operating temperatures allows determination of when use of exhaust gas temperature sensor measurements is allowable for engine diagnostic. One approach implements a physical model of pressure and temperature drops across a dual stage waste-gated turbo-charger along with modifiers based on current operating conditions to estimate the temperature in the exhaust manifold. Another models combustion to estimate the temperature in the exhaust manifold.

Abstract: A method for determining the degree of saturation of a solid ammonia storage material in a storage unit includes activating a heater to release ammonia from the storage material until the pressure of the storage unit reaches a predetermined pressure. The method then deactivates the heater and determining a decay rate of the pressure of the storage unit while the heater is deactivated. The method estimates the degree of saturation of the ammonia storage medium in response to the decay rate. According to some embodiments, determining the decay rate may include measuring the time required for the pressure of the storage unit to drop from a first pressure threshold to a second pressure threshold.

Abstract: An ammonia abatement system and method for an exhaust system that includes a threeway catalytic converter (TWC) and a diesel particulate filter (DPF). Exhaust gas entering the TWC above the stoichiometric point (_ > 1) may result in the formation of elevated levels of ammonia in the exhaust gas. To prevent the increased quantities of ammonia from skipping through the DPF, the DPF includes a catalyst to oxidize some of the ammonia and an acidic material to adsorb and store at least a portion of the excess ammonia. The acidic material may also release at least some of the adsorbed ammonia when a lean exhaust gas is present in the DPF. Additionally, an additive, such as copper or iron, may be added to the acidic material that may convert some of the NOx in the lean exhaust gas into nitrogen gas (or nitrous oxide) and water.
