摘要： A urea quality diagnosis system capable of accurately diagnosing the quality of an aqueous urea solution in a urea tank. A concentration and a level (L) of an aqueous urea solution inside a urea tank 16 are detected, and the quality of the aqueous urea solution is diagnosed based on a detected value of the concentration of the aqueous urea solution when the level L is equal to or higher than a predetermined value.

摘要： A selective catalytic reduction (SCR) system that can detect whether or not a float is stuck even where a water level sensor that detects a liquid level in a stepwise manner is used, including: an urea injection quantity integrating unit that integrates an injected quantity of urea to calculate an urea injection quantity integrated value; an integrated value resetting unit that, if a detected value from detection means changes, resets the urea injection quantity integrated value; and an abnormality determination unit that, if the urea injection quantity integrated value exceeds a predetermined threshold value for determination, determines a level sensor as having an abnormality.
