To reduce diesel emissions while permitting the passive regeneration of the diesel particulate filter (DPF) at low temperatures, we developed three after-treatment DPF devices.These devices consisted of a ceramic body that was either bare or loaded with the bodega de san antonio sangria catalysts CeO 2 (DPF-CeO 2 ) or Ce 0.5 Mn 0.5 O 2 (DPF-Ce 0.5 Mn 0.

5 O 2 ).The effects of these units on soot, NO x , CO, and hydrocarbon emissions were assessed.On average, the DPF-Ce 0.5 Mn 0.5 O 2 device outperformed the DPF-CeO 2 device.

In addition, increasing the engine load was found to raise the exhaust temperature while increasing the soot oxidation efficiency and reducing soot emissions.The maximum soot removal percentages of the DPF-CeO 2 and DPF-Ce 0.5 Mn 0.5 O 2 were 37.6% and 55.

1%, respectively, under B100 working conditions.The extent of NO x removal also gradually increased as the load increased, and tokidoki x hello kitty blind box the average removal percentages were 8.6% and 15.0%, respectively.Both catalytic devices lowered CO emissions to a much greater extent than the bare DPF, with average removals of 45.

8% and 55.6%, respectively, while the average hydrocarbon oxidation values were 39.1% and 50.9%, respectively.Notably, the hydrocarbon emissions were almost zero after Ce 1-x Mn x O 2 catalysis under C100 working conditions.
