Information on Urea that will be required for new diesel powered vehicles.
Hold on, here comes the next big change in diesel engines. Starting with the automotive market in 2009 and then with virtually all of the medium and heavy duty markets in the 2010 model year, diesel engined vehicles will require an additional fluid to operate.
These vehicles will require an ?aqueous urea solution? as defined by ISO 22241-1 using test methods described in ISO 22241-2:2006. This is a solution of 32.5% Urea in deionized water. This Urea solution is used as part of a Selective Catalytic Reduction (SCR) system to reduce the NOx emissions of diesel fueled engines.
These systems require that a tank of the Urea solution be installed on the vehicle. The Urea is meter injected into the exhaust stream after the turbocharger where the exhaust heat will convert it to ammonia which is then used by a special type of catalytic converter to significantly reduce the formation of NOx. This system will function as long as there is Urea available.
This is a complicated system with maintenance requirements, cold weather operability issues (Urea freezes), and quality concerns.
There is a wide ranging debate on what type of driver information systems are to be required, what will happen if the system runs out of the Urea solution, and where Urea will be available.
Enertech Labs will be offering a very high quality 32.5% Aqueous Urea Solution that will meet or exceed the requirements of all OEM?s. This product will be available beginning in 2009. We will also be offering education and training on purchasing, storing, and using these products.
