SCR system
EU Stage IV, US Tier 4f
SCR (Selective Catalytic Reduction) technology is used on Scania’s engines for
EU Stage IV and US Tier 4f to reduce the NO
X
content in the exhaust gases.
A chemical process is started by injecting reductant, an 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 NO
X
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 is available in different sizes and is heated by the engine’s
cooling system in order to avoid freezing of the urea solution; urea freezes at
-11°C. The 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 exhaust piping which is to be
adapted according to the customers installation.

The industrial engines from Scania are based on a robust design with a strength
optimised cylinder block containing wet cylinder liners that can easiliy be exchanged.
Individual cylinder heads with 4 valves per cylinder promotes repairability and fuel
economy.
The engine is equipped with a Scania developed Engine Management System,
EMS, in order to ensure the control of all aspects related to engine performance.
The injection system is Scania’s XPI (Extra High Pressure Injection), a common rail
system that in combination with SCR (Selective Catalytic Reduction) and EGR (Exhaust
Gas Recirculation) gives low exhaust emissions with good fuel economy and a high
torque. The engine can be fitted with many accessories such as air cleaners, silencers,
PTOs and flywheels in order to suit a variety of installations.
