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: A method (10) for injecting ammonia (NH 3 ) into exhaust gas upstream of a catalyst of an aftertreatment system includes the steps of determining whether a regeneration event is imminent (14) on the basis of predetermined parameters, and determining whether dosing parameters are met (22). The method (10) further includes the steps of calculating an amount of NH 3 to fill the catalyst (18) and adjusting a quantity of NH 3 dosed (22) before the regeneration event occurs.

Abstract: An ammonia (reductant) injector for delivering a ammonia into an engine exhaust stream is disclosed. Generally speaking, the injector has a body with an inlet fluidly coupled to a plurality of channels within the body, a plurality of discharge ports, each port being fluidly coupled to at least one channel, and an ammonia feed line connected to the inlet of the body. The plurality of discharge ports are preferably spaced one from another such as to optimize the dispersion of ammonia from the ports throughout a cross-sectional portion of an engine exhaust stream.

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. The method monitors the pressure of the storage unit while the heater is active to determine a rate of pressure increase in the storage unit. The method estimates the degree of saturation of the ammonia storage medium in response to the rate of pressure increase. According to some embodiments, determining the decay rate may include measuring the time required for the pressure of the storage unit to rise from a first pressure threshold to a second pressure threshold. The method may further include sensing ambient temperature and compensating the estimated degree of saturation based on ambient temperature.

Abstract: A flow manifold system for injecting a first gas into a second gas, such as, for example, a system for injecting ammonia gas into the exhaust gas of an internal combustion engine. The first gas may be supplied to the system by one or more cartridges. The system may also include a control valve that is configured to control the delivery of the first gas to the least one critical flow orifice. The critical flow orifice is configured to allow for a relatively constant volumetric flow of the first gas through the critical flow orifice when the first gas attains a critical flow. Such critical flow may allow for an accurate estimation of the flow of the first gas through the critical orifice, and subsequently to the second gas, without the use of a flow sensor.
