The US Environmental Protection Agency (EPA) has revised the emission monitoring criteria for diesel-powered vehicles. Under the new provisions, nitrogen oxide (NOx) sensors can now be used as a substitute for urea quality sensors within Selective Catalytic Reduction (SCR) systems. This regulatory adjustment is set to diminish instances of power reduction and maintenance expenses in diesel engines that stem from malfunctions in the urea system. Consequently, it offers a twofold advantage: technological refinement and bolstered market competitiveness for manufacturers of heavy-duty engines, including industry leaders like Cummins.
