eu stage iiiB
SCR (Selective Catalytic Reduction) technology is used on Scania’s engines
for Stage IIIB and Tier 4i to reduce the NO
X
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 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 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 fi tted 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 easily 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) 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.
