Diesel Exhaust Fluid (DEF)

DEF is a critical element of the Tier 4 Final aftertreatment system. The DEF you purchase should meet and display certification for one or more of the following standards: American Petroleum Institute (API), German Institute of Standardization DIN70700 or the International Organization of Standardization (ISO) 2224-1. DEF is widely available throughout North America and Europe. Popular websites such asfinddef.comandDiscoverdef.com提供有关购买商店的指南。

Maintaining Fuel Cleanliness and Quality

Cummins Tier 4 Final engines must be operated on Ultra-Low Sulfur Diesel (ULSD) with a maximum sulfur content of 15 ppm or less. This is a regulatory requirement; failure to do so will result in damage to the engine and aftertreatment system within a short period of time. This damage could cause the engine and aftertreatment to become inoperable, and failures attributable to the use of incorrect fuels will be denied warranty coverage. The High Pressure Common Rail (HPCR) fuel systems used for all Tier 4 Final engines require a new level of cleanliness. Internal components such as the fuel injectors can be damaged by particles as small as 5 microns. Injector wear reduces engine performance and fuel efficiency – and can lead to severe damage of other engine components. Fleetguard fuel filters with NanoNet media provide up to 13 times better protection against harmful particles, particularly under high vibration and fuel surge conditions.
