Emission Control Systems

DPF (Diesel Particulate Filter)

• Shortly after a main injection, the first post-injection is made to increase the combustion temperature.

• Another post-injection is made in an exhaust phase. This fuel is not burnt in the cylinder but evaporates in the combustion chamber.

• These fuel vapours burn in the oxidisation catalytic converter. The heat generated by this method increases the temperature of the exhaust gases before the particulate filter to approximately 620°C.
