The Suspect Parameter Number (SPN) is diagnostic fault code terminology found on some Caterpillar ® products using a J1939 CAN data link. The Society of Automotive Engineers (SAE) developed the J1939 standards and SPN code terms have been assigned for specific parameters (component or system circuits) that diagnostic trouble codes (DTC) are associated with.
Dosing vertically upward (against gravity) is not recommended because of higher DEF deposits and DEF crystallization risk at point of DEF injection. What is the difference between SU, DU, Dosing valve, dosing injector, pump, doser? SU= Supply Unit = pump. This is the unit providing pressurized DEF to the doser on the SCR from the tank.
This added “cleaning” effect increases engine up time by lowering the failure rates for the EGR, VGT, doser valves, DOC, and DPF. Now, let’s do the math. It takes 1 fluid ounce of the fuel catalyst to treat every 25 gallons of diesel fuel, so 1 gallon treats 3,200 gallons of diesel.
Aug 18, 2019 · The SCR system, or urea injection, used a dosing valve positioned upstream of the SCR catalyst to introduce diesel exhaust fluid (a mixture of 32.5-percent urea, 67.5-percent water) into the exhaust system. When exhaust gases react with DEF, ammonia and carbon dioxide is formed. No More Second Fiddle—Best-in-Class HP and Torque
