Opis:: Engine emissions can be reduced by performing suitable modifications to the oil filter. Biomass medium served as the replacement for the standard paper fibres, which are used in common oil filters. The experimental analysis of 4 emission elements showed a moderate increase in the case of 2 emission characteristics, whereby a 10% increase in monoxide was present, and also, an increase of 2.5% of nitrogen oxides was observed. Further, there was a significant reduction of 2 other emission elements, namely the unburned hydrocarbons decreased by 61%, and the amount of particulate matter was reduced by 18%. Measured engine power increased by 1.2% using the modified oil filter, which proves the success of this filter. There was a decrease in oil pressure as well, the value dropped by 0.5 bar during the whole period of the measuring process.

Opis:: The aim of the article was to analyze changes in the trends of selected physical, chemical and functional properties of lubricating engine oil operating in a diesel-engine vehicle equipped with DPF. The vehicle was operated mainly in urban driving conditions (app. 70%), which impeded the DPF regeneration cycle and caused dilution of oil with unburned fuel. Changes in the following physical and chemical properties were assessed: the DF level in engine oil, viscosity (kinematic, dynamic HTHS and structural CCS), total base number, acid number as well as the degree of oxidation, nitration and sulphonation. The tests have shown that the amount of unburned fuel that goes to the engine crankcase due to the unfinished DPF regeneration cycle is as high as 26.0-34.6%. Dilution of the lubricating oil with fuel leads to a significant reduction of its viscosity - about 30% of the fuel content causes a decrease in the kinematic viscosity measured at 100°C to the level of 7.7 mm2/s. There was also a significant decrease in total base number (TBN) < 2 mg KOH/g, and an increase in the total acid number (TAN). Moreover, the results obtained were analyzed for potential effects that could have been caused during prolonged engine operation by assessing the content of trace elements in the samples taken.

Opis:: This paper provides a general review of light-duty (LD) and heavy-duty (HD) regulations, engine technology, and key emission control strategies. The US is placing a stronger emphasis on laboratory emissions, and the LD regulations are about an order of magnitude tighter than Euro 6, but Europe is focusing on real-world reductions. The California HD low-NO_x regulation is advancing and may be proposed in 2017/18 for implementation in 2023+. The second phase of US HD greenhouse gas regulations propose another 25-30% tightening beyond Phase 1, beginning in 2021. LD and HD engine technology continues showing marked improvements in engine efficiency. LD gasoline concepts are closing the gap with diesel. HD engines are demonstrating more than 50% BTE using methods that can reasonably be commercialized. LD and HD diesel NO_x technology trends are also summarized. NO_x storage catalysts and SCR combinations are the lead approach to meeting the LD regulations. Numerous advanced NO_x technologies are being evaluated and some promise for meeting the California HD low NO_x targets. Oxidation catalysts are improved for both diesel and methane oxidation applications. Gasoline particulate filters (GPF) are the lead approach to reducing particles from gasoline direct injection (GDI) engines. They reduce PAH emissions, and catalyzed versions can be designed for low back pressure. Regeneration largely occurs during hot decelerations.
