Influence of Emissions Reduction and Fuel Saving on Torsional Vibrations

  • Torsten Philipp
Development Torsional Vibrations

Measures affecting the combustion processes of large diesel and gas engines aimed at improving exhaust emissions, reducing fuel consumption and raising power density result in new combustion characteristics. Addressing their effects on the pattern of torsional vibrations produced at the crankshaft continues to be a major task for torsional vibrations specialist Geislinger.

Engine development aims and torsional vibrations

Compliance with emissions regulations has been one of the main development targets for the large engine industry during the past 25 years and more.

Rules like IMO Tiers II and III for marine engines and EPA Tier 4 for land-based off-highway applications have led to intensive development activity.

The drastic reduction in oxides of nitrogen (NOx) and particulate matter (PM) is typically achieved not only by optimising a single engine parameter or component, but by a combination of technical enhancements and modifications. Internal measures target the combustion process...
