| abstract |
It is proposed a module (100) for use on-board a vehicle. The module comprises a heater (50) and at least a first and a second storage compartment (10; 20; 30; 40; 20', 40'). The first compartment at least partially surrounds the heater (50), and the second compartment at least partially surrounds the first compartment. The first compartment is configured to perform a first function in a first temperature range, and the second compartment is configured to perform a second function in a second temperature range, said second temperature range being lower than said first temperature range. The first compartment is in fluid communication with the second compartment. One function of said first and second function is receiving an ammonia precursor, and decomposing the ammonia precursor using a catalyst to generate an ammonia solution. |
