Wärtsilä Emission Measurement Services

Emissions measurement by Wärtsilä engineers ensures compliance with environmental regulations. The analysis results give an overview of the engine’s condition and indicate which components need to be adjusted to reach emission limits and improve performance.

Tighter environmental regulations call for advanced emission controls and near-zero diesel emission levels. Emissions limits are set by the authorities in most industrialised countries, with regular measurements to check compliance. Targeting lower emission levels means that the methods for measuring and controlling them must become more accurate and reliable.
