L250MDC Marine Engine Family

The L250MDC EPA T4 & IMO III emissions-compliant engine series is the most technologically advanced and fuel-efficient medium-speed diesel engine ever built by Wabtec. The L250MDC marine diesel engines are certified to meet EPA Tier 4 & IMO III emissions standards through advanced exhaust gas recirculation that requires no urea-based after-treatment. This advanced technology limits the formation of NOx in cylinder as opposed to removing NOx from the exhaust through an after-treatment system, while maintaining world-class fuel efficiency.

Benefits

• Eliminates the need for space and weight provisions otherwise needed for an SCR system and urea storage tanks, preserving valuable cargo, accommodation, and tank space
• No additional operating expenses from urea use and catalyst replacements
• No hassle associated with planning for urea replenishment and handling urea onboard
• Reducing ship design complexity and shipyard installation time and cost compared to an engine with an SCR after treatment solution
• Robust and proven design, simple to operate
• World-class fuel efficiency and load response with practically no visible smoke
• High engine energy efficiency with more heat recovery available in jacket water system from EGR
• Narrow footprint allows ease of maintenance and packaging advantage
