Cat 3500 Series Marine Emissions Kits Certified by the EPA

7/29/2011

Caterpillar Marine Power Systems and Caterpillar Emissions Solutions announced that the United States Environmental Protection Agency has certified Cat 3500 Series Marine Emissions Kits according to EPA Rule 40 CFR Part 1042. This Marine Remanufacture Program applies to many commercial engines flagged or registered in the United States, and the requirements include a 25 percent particulate matter reduction at overhaul. By replacing the mechanical unit injector (MUI) system and other associated components on the engine, the upgrade kits offer vessel owners an in-hull solution that exceeds the requirements, and offers operational benefits.

Offering sustainable solutions to customers and the market at large is a driving force within the Caterpillar enterprise. Caterpillar is powering change by leveraging technology and innovation to increase efficiency and productivity with less impact on the environment and helping our customers do the same – enabling their businesses to become more productive by providing products, services and solutions that use resources more efficiently.

Reducing emissions is a key imperative within the Caterpillar sustainability strategy and the 3500 Emissions Upgrade Kits are an example of aligning sustainability with innovation to help our customers. Aside from the compliance and environmental benefits, an upgrade from a mechanical to an electronic EPA Tier 1 or Tier 2 configured engine can also result in numerous operational improvements. These benefits include improved diagnostic and display capabilities as well as smoother overall operation. As confirmed by multiple customers, an upgrade solution during the overhaul can result in lower vibration and noise levels, and a significant fuel savings. A lesser known advantage of electronic fuel injection engines is that they offer superior brake specific fuel consumption in the midrange versus a traditional mechanical fuel injection engine.  “In many cases, we observe that our customers operate a significant percentage of their time below the rated power and speed, meaning that this upgrade kit will translate into both emissions reduction and operating cost savings over time,” Tetrault noted.

Emissions upgrade kits for Cat 3500 Series marine propulsion engines are currently available for order from Caterpillar. The kits are also available internationally for customers but compliance will depend on local acceptance. Customers should contact their local Cat Dealer to determine applicability based on existing engine serial number and operation profile. For more information, please visit http://marine.cat.com.
