REDUCTANT INJECTION CONTROL SYSTEM |
摘要 |
<p>A control system for reducing nitrogen oxides in an engine exhaust of an engine includes an emissions catalyst having an inlet adapted to receive an exhaust from the engine. A reductant tank stores a reductant. An injector is in fluid communication with the reductant tank and is operable to inject the reductant into the exhaust upstream of the catalyst. A reductant pump pumps the reductant from the reductant tank to the injector. A controller determines a target pressure of the reductant based on an engine operating condition and operates the reductant pump based on the target pressure.</p> |
