GE Transportation’s marine diesel engines meet EPA Tier 4 emission standards through advanced exhaust gas recirculation (EGR) technology without a urea-based SCR aftertreatment system.

At GE Transportation, now a Wabtec Company, we understand that no operator would be keen on incurring additional operating expense to meet the EPA Tier 4 emissions standards. Our EGR technology limits the formation of NOx in cylinder as opposed to removing NOx from the exhaust through an aftertreatment 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. No urea. No kidding!

Engine room space and engine weight are critical - that is why we made sure that our EPA Tier 4 engine is similar in size and weight to engines that meet prior emission standards. With our solution, we eliminate the need for spacious provisions required for an SCR aftertreatment system and urea storage tanks, preserving valuable cargo, accommodation, and tank space. We can save up to 75 % of required vessel space and engine system weight compared to an SCR solution.

Our proven solution is less complex to install and operate, produces practically no visible smoke, has world class fuel efficiency and load response, and avoids the hassle of planning urea replenishment and onboard handling of urea. No urea. No kidding!
