Abstract: This study examines particle and gaseous emissions from a light-duty diesel vehicle equipped with a partial-flow catalyzed diesel particulate filter (P-CDPF). The vehicle underwent testing on a chassis dynamometer following the new European driving cycle. The results show a significant reduction in total hydrocarbon (THC) and carbon monoxide (CO) when employing P-CDPF. Specifically, catalytic coating successfully converted 48% of THC and 66% of CO into carbon dioxide (CO2). This resulted in a 6% increment in CO2 emissions after the driving cycles. Nitrogen oxides (NOx) increased after P-CDPF because of elevated in-cylinder temperature due to backpressure. Additionally, the integration of P-CDPF resulted in a 45% reduction in particulate number (PN) and a 60% reduction in particulate mass (PM). The findings of this study propose a feasible solution for controlling harmful substances, thereby contributing significantly to practical initiatives aimed at reducing harmful emissions emitted by untreated diesel vehicles
