4.7 Emission 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 (EURO 5 and future ones). This comprises technologically enhanced en‐
gines with an increased peak pressure improving the combustion and reducing the number of parti‐
cles. Furthermore, all engines are fitted with various after-treatment facilities.
These facilities contribute to the protection of human health and the environment.
