Reducing the sulphur content of marine fuels

Reducing the sulphur content of marine fuels

IMO’s MARPOL Annex VI legislation has so far been based on the concept of SECAs, i.e. it seeks targeted sulphur reductions in those specific areas where emission density is high and sulphur impacts from ships are comparable to those from land-based sources....
Particle emissions from modern vehicles

Particle emissions from modern vehicles

Ultra-low sulphur fuels have enabled the introduction of modern engine and after-treatment technologies in order to meet increasingly stringent exhaust emissions limits. Through these improvements, substantial reductions in road vehicle emissions have occurred over...
Advanced combustion engines for low emissions and high efficiency

Advanced combustion engines for low emissions and high efficiency

Air pollutant emissions from motor vehicles have fallen dramatically over the past two decades as a result of continuing improvements in engine and after treatment technologies to meet lower regulated emissions limits, and in the quality of fuel used to power these...
