V250MDC Marine Engine Family

Wabtec’s V250MDC marine diesel engines meet US EPA Tier 4 & IMO III emissions standards without after-treatment: clean, simple and evolutionary. Our EGR 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. Our solution offers OPEX savings by avoiding any additional operating cost from urea consumption, SCR catalyst replacements, and maintenance on the SCR dosing system.

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
