MAN Truck Parts DPF Diesel Particulate Filter/Catalytic Converters Used In Exhaust System OEM:81151030164 81151039107 81151039130, 81151039164

Modern diesel engines use an integrated after-treatment system—comprising DOC, DPF, and SCR Catalyst Converters—to meet strict emission standards like Euro VI and EPA Tier 4. The DOC oxidizes CO and HC, the DPF traps particulate matter, and the SCR reduces NOx using urea. Beyond on-road vehicles, these systems are engineered for industrial and stationary equipment such as generators, construction, and agricultural machinery. Customized solutions are available to endure harsh conditions—high sulfur, variable loads, and extreme temperatures—ensuring compliance, durability, and optimal performance for diverse operational needs and regulatory environments.
