The L250MDC EPA T4 & IMO III emissions-compliant engine series is the most technologically advanced 和 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 st和ards 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.
