A fluid dispensing apparatus is provided and is configured to dispense two fluids to a vehicle. A rigid diesel spout delivers diesel, while a urea spout is slidably disposed on the diesel spout and configured to deliver urea to the vehicle. The urea spout includes a guide that cooperates with a rail on the diesel spout such that insertion of the diesel spout into the vehicle can slide the urea spout relative the diesel spout. A valve in the urea spout includes an area for receiving a projection member on the vehicle to open the urea spout when inserted into the vehicle. The vehicle correspondingly includes a diesel intake and a urea intake. A projection or pin is provided to cooperate with the dispensing apparatus to open the valve and allow urea to flow into the vehicle.

A diagnostic system and method for diagnosing the performance of a particulate matter (PM) filter of an exhaust system each involve receiving, by a controller from at least one sensor, a gas component measurement of exhaust gas flowing through the exhaust system and the PM filter. The controller calculates a conversion efficiency of the gas component by the PM filter and compares the calculated conversion efficiency to a predetermined conversion efficiency threshold indicative of an expected conversion efficiency of a flow-through catalyst. The controller then determines whether the PM filter is cracked or damaged based on the comparison between the calculated conversion efficiency and the predetermined conversion efficiency threshold.

A catalyst degradation detection method for use with a zero ceria catalyst. The method uses techniques to measure transient responses to engine control events of upstream and downstream sensors to determine catalyst degradation and performance. By measuring transient behavior, the method can determine catalyst degradation and performance based on the limited oxygen storage of precious metal catalysts that do not include added ceria or other materials with high oxygen capture rates.
