Biggest Engine

Playing the Tier Game

By Larry Pearson With few exceptions, marine power is diesel power and emissions levels from diesel engines are coming under increased scrutiny and regulations from the Environmental Protection Agency. The levels of acceptable NOx, carbon monoxide and particulate matter for diesel engines in U.S. flagged vessels depends on the displacement of the engine. The EPA has settled on a liters-per-cylinder measurement to determine the schedule to meet the emission requirements. For example, marine diesel engines between 1.2 and 2.5 liters per cylinder have had to meet what is known as Tier Two requirements since 2004. These are engines typically used to power small gensets, bow thrusters, fire pumps and other auxiliary engine requirements. However, not all of the engines between 1.2 and 2.5 liters per cylinder have to meet Tier Two requirements. "Engines used for emergency generators and other standby power are exemption from these regulations," said Gary Aucoin, marine sales manager for Louisiana Machinery Inc., Belle Chasse, La., a Caterpillar distributor and major supplier of diesel engines for shipyards in Louisiana. Larger engines, between 2.5 and 5.0 liters per cylinder must today meet less stringent emissions standards known as Tier One. These engines are used for main power requirements of marine vessels.


New Diesel Engine Lines Available for Workboat Market

In recent months several diesel engine manufacturers have expanded their existing engine and generator ranges to include models suitable for workboat, large yacht and fishing vessel applications. This translates to more propulsion choices for boat builders and owners. Following is a look at four newly launched lines. MTU Friedrichshafen's 8000 Series Last September, MTU introduced the new 8000 series, moving the company into medium-speed engine market.


Ingram Repowers With Cummins
