Description and Purpose
The DEF Doser Fluid Supply Module (Part Number: 2880158) by Cummins® accurately introduces Diesel Exhaust Fluid (DEF) into the exhaust flow, indispensable for the Selective Catalytic Reduction (SCR) system to diminish nitrogen oxide (NOx) emissions and satisfy environmental standards.
Importance of Replacement
A defective DEF Doser may obstruct DEF injection, impairing SCR effectiveness, increasing NOx outputs, weakening engine performance, and risking breaches of emission requirements. Swift replacement helps secure proper emission regulation and stable engine function.
Impact on Vehicle Performance
A fully operational DEF Doser ensures exact DEF dosing, enabling significant NOx reductions, conformity with ecological policies, and optimal engine output, which includes higher fuel efficiency and prolonged service life. Sustaining the DEF system is essential for vehicle wellness and regulatory adherence.
