Diesel-powered cars from Audi and Peugeot have been winning the 24 Hours of Le Mans each year since 2006. This is not a coincidence. Diesel represents the future in motor engineering.
With ASDS-2, diesel engines will be brought to the next level. The ASDS-2 is a highly efficient de-NOx system for midsize cars, full-size cars and SUVs.
Making no use of urea, the ASDS-2 is instead based on AdAmmine, and the system makes it possible to release an accurate dose of pure ammonia directly into the exhaust system.
The ASDS-2 is heated by the engine coolant and contains a replaceable cartridge with 9 litres of AdAmmine as well as a small start-up unit that ensures short time-to-dose even at temperatures well below 0° C.
This makes the ASDS-2 very suitable for urban driving over short distances with frequent cold starts of the engine.
In collaboration with the OEM, the capacity of the cartridges can be adjusted to last a standard oil service interval. In other words: The end-user will not have to do any refilling. The main cartridges will be replaced when the car is serviced.
The start-up unit is a permanent part of the car, and is recharged during normal driving.
The control system is electronic, and the ASDS software can be layered in the engine control unit as well as in the dosing control unit or in a separate ASDS controller.
