Reductant fill system |
| 摘要 |
A reductant fill system is provided. A reductant tank is configured to store a reductant. A receiver is configured to receive a supply of the reductant from an off-board reservoir. A first valve is in communication with the reductant tank and is configured to control a reductant flow into the reductant tank. A reductant supply line is in fluid communication with the receiver. The reductant supply line is configured to provide the reductant flow to the first valve. The reductant level sensor is configured to generate a signal based on a level of reductant in the reductant tank. A controller is communicably coupled to the reductant level sensor. The controller is configured to purge a stranded reductant in the reductant supply line, based on the signal generated by the reductant level sensor. |
