4.7 Exhaust gas after-treatment
The exhaust from a diesel engine contains invisible particles that are dangerous to health.
State-of-the-art engine technologies are used to reduce the emission of pollutants and to meet the
tighter exhaust standards.
For a proper balance, all parameters affecting combustion must be optimally adjusted to each oth‐
er. In interaction with injection and turbo-charging in particular, the exhaust gas recirculation allows
for combustions with significantly less nitrogen oxides.
