sCr system
us tier 4i, eu stage iiiB

SCR (Selective Catalytic Reduction) technology is used on Scania’s engines

for Stage IIIB and Tier 4i to reduce the NOX content in the exhaust gases.
A chemical process is started by injecting reductant, a urea and water
mixture, into the exhaust gas stream. During injection the water evaporates
and the urea breaks down to form ammonia. The ammonia then reacts
with the nitrogen gases in the catalytic converter and forms harmless
products such as nitrogen gas and water. Through the use of SCR the
exhaust gases are purged of poisonous levels of NOX in the best possible
way. Scania is making use of a system that is carefully developed and
tested in our own laboratory.

The reductant tank holds 38 or 60 litres and is heated by the engine’s

cooling system in order to avoid freezing of the urea solution, urea
freezes at -11°C. The reductant tank and a pump module are delivered
as a unit which is fitted to brackets for an easy installation. The Scania
system contains all mechanical and electrical parts needed except from
The principle for Scania SCR system the exhaust piping which is to be adapted according to the customers
installation.
