“…Moreover, the surplus oxygen content in nbutanol contributed to the reduction in NOx emissions. The decline in the level of PM emissions could also be associated with the inclusion of n-butanol in the blends, as was, particularly observed in the blends during lowload conditions [48]. Hence, blends containing nbutanol exhibit favourable engine performance and lower CO2 and PM emissions, establishing them as a promising fuel choice.…”

Aims: This study investigates the impact of blending n-butanol with diesel fuel on the performance of a single-cylinder, 4-stroke diesel engine under varying engine loads. Study design: The performance assessment followed SAE J1349 on a Tec-Quipment TD110-115 4-stroke engine at 1500 rpm with varying loads and fuel samples. Place and Duration of Study: The study was conducted for 2 months the at Automotive Engineering Technology Workshop, Federal Polytechnic, Bauchi Nigeria. Methodology: The SAE J1349 test protocol was followed, using diesel fuel (D95) and different blended fuel samples (D90, D85, D80, D75, and D70). While diesel fuel generated higher brake power due to its higher calorific value, the D95 blend demonstrated comparable performance to diesel fuel across all parameters. Results: The brake power of the D95 blend initially decreased by 69.7% and then increased as the load increased to 2500g and 3000g, indicating improved combustion due to oxygenation. The D95 blend exhibited lower fuel consumption compared to diesel fuel, although blends with higher n-butanol percentages showed increased brake-specific fuel consumption due to lower calorific values, densities, and viscosities. Under maximum load, the D95 blend exhibited higher exhaust gas temperature and heat loss, reflecting the increased fuel quantity required for additional power. Lower heat losses at lower loads were attributed to factors such as lower calorific values, n-butanol's heat of vaporization, temperature differentials between the exhaust and ambient conditions, and engine size. Conclusion: The engine load has diverse effects on parameters across different fuel samples. D95 exhibits similar performance to diesel, yet discrepancies arise, especially with higher n-butanol content at lower loads.

“…The diesel engines have many advantages for medium-to-heavy ground vehicles such as high thermal e ciency [1][2][3][4][5] . However, the particulate matter (PM) emission from diesel engine has been a huge problem to the environment [6][7][8][9][10] . The PM includes carbon, ash, organic compounds, and sulfate materials [11,12] .…”

This paper discusses the influence of partial region regeneration on both regeneration and emission performance by regeneration test bench. DPF substrate is divided into following four regions on the radial direction by the distribution of thermocouples. For the single region regeneration, region 2 has the highest maximum temperature, maximum temperature gradient, average diameter. The regeneration efficiency decreases when the loading area is far away from the center. The maximum total mass concentration is 0.36mg/m3 at region 4 due to the mass of carbon black loading. For double regions regeneration, the center and adjacent regions have positive effect on maximum temperature, maximum temperature gradient, regeneration efficiency and regeneration performance ration. The maximum total mass concentration and maximum average diameter are 0.2mg/m3 and 34nm at regions 14. For multiple regions regeneration, the lowest maximum temperature and the maximum temperature gradient are 565℃ and 8.3℃/m at regions 134, respectively. Regions 123 have maximum regeneration efficiency, performance ratio, total mass concentration and average diameter. The maximum and minimum average diameters are 101.8nm and 30.2nm at regions 123 and regions 134, respectively.

“…The primary fuel of modern compression-ignition engines is diesel fuel. Due to the depletion of fossil fuels, especially oil, climate change, economic problems, population growth and energy demand, intensive research work is being carried out to obtain alternative fuels to diesel [47][48][49][50][51][52]. For this reason, research on compression-ignition engines fueled by fuel blends as an alternative to diesel fuel is gaining great importance in the direction of performance and emissions.…”

“…In addition, during the study of engines with alternative fuels, the influence of various design and operational parameters is evaluated in the direction of reducing exhaust emissions. For example, in [47], a study was conducted on a common-rail diesel engine to evaluate the effect of a diesel-butanol blend on particulate matter (PM) emissions using a pilot injection strategy. The addition of nbutanol can improve the mixing of fuel and oxidizer and lower the average temperature in the combustion chamber and consequently reduce NO x emissions (up to 25%) and PM emissions (up to 69%).…”

The results of an experimental study of the effect of the pressure drop of the air filter pf on the operat-ing parameters and exhaust emissions of a modern CI internal combustion engine of a truck equipped with an electronically controlled power system are presented. 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. It was found that an increase in the filter resistance pf causes a decrease in the filling degree by 12%, engine useful power by almost 10%, exhaust gas temperature by a maximum of 30oC and an increase in specific fuel consumption by almost 5%. Air filter resistance has no significant effect on NOx emissions and HC concentration. There is a reduction in H2O emissions by up to 7%, CO by up to 13% and CO2 by up to 4%, and an increase in oxygen emissions by 15%, depending on operating conditions.
