Empirical study of the effect of the air filter on the performance and exhaust emissions of a diesel engine
Published 2023-03-01“…The tests were carried out for an air filter with a clean filter cartridge Δpf0 = 0,58 kPa and with a cartridge contaminated after a service mileage (about 50 thousand km) ΔpfD = 2,024 kPa. In each test, engine performance, exhaust emissions and relative change in emissions were determined: CO, NOx, HC, CO2, H2O. …”

Experimental Evaluation of the Effect of Replacing Diesel Fuel by CNG on the Emission of Harmful Exhaust Gas Components and Emission Changes in a Dual-Fuel Engine
Published 2023-01-01“…The use of a dual-fuel system had a positive effect on the emissions of some harmful exhaust components, even in an engine from a vehicle that had been running for many years on diesel and at high mileage, but, simultaneously, the emissions of some harmful exhaust gas components increased.…”

Experimental Assessment of the Impact of Replacing Diesel Fuel with CNG on the Concentration of Harmful Substances in Exhaust Gases in a Dual Fuel Diesel Engine
Published 2022-06-01“…The test results confirm that, compared to conventional fueling, the diesel/CNG-fueled engine allows for a significant reduction in CO<sub>2</sub> concentration even in a car operated for several years with diesel fuel and with high mileage. The use of a non-factory installation significantly increased the concentration of methane CH<sub>4</sub>, nitrogen dioxide NO<sub>2</sub> and carbon monoxide CO in the exhaust gas. …”
