摘要： A computer program, system and method are provided for thermally regulating an injector injecting a reducing agent into an exhaust pipe of an internal combustion engine. A pump is activated to deliver a coolant in a coolant circuit having a portion in heat exchange relation with the injector. A value is determined for a mass flow rate of the coolant delivered by the pump. A value is calculated for a temperature of the injector as a function of the determined value of the mass flow rate. A difference is calculated between the calculated value of the injector temperature and a predetermined set-point value thereof, and the mass flow rate of the coolant delivered by the pump is adjusted on the basis of the calculated difference.

摘要： An exhaust gas control apparatus and method for an engine includes a urea water supply mechanism that adds urea water to exhaust gas, a SCR catalyst that adsorbs ammonia and removes NOx in the exhaust gas by using the adsorbed ammonia, and a control device that controls a urea water addition amount based on a target adsorption amount for the ammonia adsorbed onto the SCR catalyst. The control device executes an integration processing that acquires a temperature of the SCR catalyst at a predetermined cycle and integrates the acquired temperature of the SCR catalyst when equal to or higher than a threshold, and an initialization processing that decreases the amount of the ammonia adsorbed on the SCR catalyst on a condition that an integrated value of the temperature of the SCR catalyst calculated in the integration processing has become equal to or higher than a predetermined value.

摘要： An injector for delivering a working fluid into a working environment is disclosed. According to one embodiment of the present invention, the injector includes a pre-metering chamber and a swirl chamber. A high velocity partially atomized flow is produced in the pre-metering chamber through a first exit nozzle after impinging on an atomization element, and then a swirling flow is created in the swirl chamber with the atomization element. When the swirling flow is released through a second exit nozzle, atomization can be achieved at low injector pressure with centrifugal force and shearing of the working fluid. In another embodiment, the injector includes a swirl chamber and an atomization element with a bore, through which a control valve is positioned. The control valve forces a working fluid flow through the atomization element when the injector is energized to create a swirling flow. No flow-back is required for the injectors.
