Multiquip 8982465062 DEF DCM Exhaust NOX Sensor - OEM Replacement Part

This DEF (Diesel Exhaust Fluid) DCM exhaust NOX sensor monitors nitrogen oxide emissions in the exhaust stream of Tier 4 Final compliant super silent generators, providing critical feedback to the emission control system to ensure compliance and optimal engine performance. The sensor works in conjunction with the diesel oxidation catalyst (DOC) and selective catalytic reduction (SCR) systems to maintain proper aftertreatment operation.

Designed specifically for the DCA70SSIU4F super silent generator equipped with the Deep Sea DSE8610 MKII/MKII-U2 controller, this sensor is essential for maintaining emissions compliance and preventing system derates. The exhaust aftertreatment system requires proper maintenance to prevent carbon accumulation—operators should run the unit at rated power periodically until exhaust gas becomes mostly colorless every 250 hours, especially when operating below 30% of rated power to minimize soot buildup that could trigger sensor faults or system warnings.

Compatible with the following Multiquip generator models:

• DCA70SSIU4F
