Marine Emissions

Better. Compliance Worldwide.

Cummins is in the vanguard of supporting the environment, earning the first Environmental Protection Agency (EPA) Tier 2/IMO emission standards certification for our new wave of diesel marine power, the Quantum Series.

Our engineers continue to advance this new wave of diesel power, built around fuel systems that provide better power-to-weight ratio, cleaner starting, less noise and virtual elimination of smoke and odor traditionally associated with diesel engines.

A summary of current and near-term regulations is listed below.

  • IMO - The International Maritime Organization has issued Regulation 13 to Annex VI of MARPOL 73/78, which was enforceable from January 1, 2000 for diesel engines above 130 kW (174 hp) installed on a vessel. This regulation exempts diesel engines used exclusively in emergency applications.
  • EC - The Nonroad Mobile Machinery Directive regulates exhaust emissions from various mobile sources in the European Community. As of January 1, 2007 the scope of the Directive extends to those propulsion and auxiliary engines used aboard inland waterway vessels. The Directive contains a phased implementation based upon per cylinder displacement and application of the subject engine. For all propulsion engines and auxiliary engines greater than 560 kW, Stg IIIa limits apply. For auxiliary engines less than 560 kW, Stg II limits apply.
  • CCNR - In July 2007 (vessel in-service), the Central Commission for the Navigation of the Rhine (CCNR) implemented its Stg II emissions regulation for diesel engines. In an amendment to the CCNR regulation, EC type certification according to the directives of the European Union is considered equal to the CCNR's Stg II certification. Therefore, engines certified to the EC Nonroad Mobile Machinery Directive will be accepted without direct certification to the CCNR regulation.
  • EPA - On January 1, 2004, the Environmental Protection Agency mandated Tier 2 emission regulations for new commercial marine diesel engines installed on vessels flagged or registered in the United States.
