Above 35° C (95° F) test quality before use Refer to "ISO 22241" document series for more information about DEF quality control.Note: Dispose of all fluids according to applicable regulations and mandates.DEF/Urea Solution Recommendations for Marine Engines
The US has adopted/approved NOx Emissions Control Area (ECA) regulations. Per ECAs, vessels that are 2016 and later models, or vessels that are modified to 2016 models, are required to meet Tier III NOx standards. These engines may require the use of Diesel Exhaust Fluid (DEF) and other urea solutions for engines equipped with Selective Catalytic Reduction (SCR) systems. If required, Cat marine engines are designed to operate on DEF of urea concentrations of 32.5 percent (by weight) or 40 percent (by weight). The crystallization temperature of 40 percent urea solution is 0° C (32° F). If urea solution ambient temperatures are routinely below 5° C (41° F) and supplemental heat is not applied to urea storage, then 32.5 percent solution should be used and maintained at a temperature above −0° C (14° F). Urea solutions should be maintained above the specified freezing temperature. Consult the urea supplier and follow the guidelines provided in this article for handling and recommendations.Vessels that are traveling internationally and have on/off NOx controls that allow the vessels to meet ECA regulations must enable NOx controls prior to entering the ECA. For US flagged vessels, the SCR must be activated and deactivated automatically based on input from the Global Positioning System. For US flagged vessels, on/off NOx controls are allowed on engines > 30 liters/cylinder and are not allowed on engines < 30 liters/cylinder unless installed on a vessel with propulsion engines >30 liters/cylinder. Otherwise the NOx control systems on Category 1 and 2 engines must always be on. Foreign destinations should be reviewed for supply of ULSD fuel and DEF prior to departure. Exemptions for ULSD or DEF use due to fluid unavailability per 40 CFR part 1042.650(a) by US flagged vessels operating outside of US waters may be requested from the US Environmental Protection Agency (EPA). The EPA can be contacted at the following address:complianceinfo@epa.gov
When used in marine engines, DEF of 32.5 percent urea concentration must meet all the guidelines and quality recommendations given in this Chapter.When used in marine engines, urea solution of 40 percent urea concentration must follow all the DEF guidelines and quality recommendations given in this chapter and must meet the characteristics listed in Table 5 for 40 percent concentration. The supplier should provide documentation to prove that the urea solution is compliant with the characteristics published in Table 5.Refer to your engine Operation and Maintenance Manual to determine the concentration of urea solution allowed in your engine.
