AMMONIA GENERATING SYSTEM FOR USE IN A VEHICLE

摘要

A system, control module and method for use on board a vehicle, the system comprising: a decomposition tank configured to hold an initial ammonia precursor solution and an initial quantity of biological catalyst, wherein the biological catalyst is suitable for decomposing the ammonia precursor into ammonia; and a controller configured to control addition of ammonia precursor and/or biological catalyst to the decomposition tank; wherein the controller is configured to add a controlled amount of ammonia precursor and/or biological catalyst to the decomposition tank once the ammonia precursor in the initial solution in the decomposition tank has been at least partially decomposed.
