“…The research was conducted to learn how thermal brake efficiency changed across a wide range of operating speeds (700-1900rpm) while maintaining constant torque. The Heenan-Froude hydraulic dynamometer engine test bed (Nwakaire et al, 2020) was used to conduct the fuel comparisons, with pure petroleum diesel (B0) serving as the reference standard.…”

Biodiesel made from the transesterification of plant-derived oils is an important alternative fuel source for diesel engines. Several disparate studies have emphasized the significance of biodiesels in emission reduction and engine efficiency. The present study examined the effect of using palm kernel oil (PKO), pure petroleum diesel, and its blends on the fuel consumption rates, energy expended, brake-specific fuel consumption, and brake thermal efficiency of a four-cylinder tractor under varying operating speeds (700 – 1900rpm) at constant torque. The study was conducted at a large farming site in Anambra State, Nigeria. The findings indicated that PKO biodiesel blends had the overall optimum energy output, fuel consumption rates, and brake-specific fuel consumption, respectively, at the highest engine speed of 1900. Although B10's rating of 60.6% for thermal brake efficiency was impressive, it was lower than B100's 66.95 %. Based on the results, B10 is the best gasoline for testing and may be used as a replacement fuel in four-cylinder farm tractor engines with no modifications. The study concludes that biodiesel blends showed potential as an alternative to fossil diesel.

“…Methanol produced from coal and other waste resources into liquid fuel was found particularly useful for traction purpose in DEL [91]. Among the other renewable fuels in the blended form for DEL are biodiesel, bioethanol, and bio-methanol [92,93]. However, the demerits are deterioration of the biodiesel and corrosion effects on the copper and brass parts of DEL [91].…”

This work presents the review of locomotives and the future of railway automotive power in Africa. Locomotives down time on account of inadequate spare parts still remains a challenge in African. It is thus, imperative to review the locomotives in African, to establish the current capabilities as well as provide recommendations to bridge the gaps and its extrapolated trends in future. Firstly, the comparison factors were track length, electrified rails, number of locomotives and yearly passengers on each of Egypt, Ghana, Kenya, Nigeria, South Africa and Zambia rails. Secondly, the focus was on engine parameters from literatures and maintenance logbooks of locomotives. From available data, it was found that South Africa and Egypt have more advanced rail system than the rest four selected countries. It was also found that additive manufacturing, 3D printing, ductile cast iron and die-forging can be used to produce the engine body for diesel engine using steel and aluminum alloys while aluminum silicon and tin doped with copper are good for reciprocation mechanisms. And finally, increased reliability of locomotives can be guided by an engine selection matrix, while use of renewable and energy hybridization are needed to meet the expansion of railroads in Africa.

“…They also reported 6% increase for BSFC. Nwakaire et al [ 15 ] studied engine performance with different ratios of biodiesel blended in diesel fuel and claimed an improvement, compared to diesel fuel, of up to 26%; in addition, they reported low BSFC for biodiesel combustion. However, one of the major problems with biodiesel application as fuel is its oxidation stability.…”

Biodiesel is considered as a key prospective renewable energy source in India. Hence, a study was carried out for the improvement of palm kernel oil biodiesel production using a transesterification process at different molar ratios. This study comprehensively examined all aspects of biodiesel from optimum production to the effect of additives on its combustion behavior. The optimum yield condition was validated with the MINITAB-17 software and analyzed using the Taguchi method. Two different additives, 5% diethyl ether (DEE) and 2000 ppm Butylated hydroxyltoluene (BHT), were also experimented. Engine experiments were conducted at constant speed (1500 rpm) and five different engine loads (0, 25, 50, 75 and 100%) on a single-cylinder direct injection diesel engine. Heat release rate, brake specific fuel consumption, brake thermal efficiency, engine emissions, such as CO, HC, NOx, and smoke opacity were analyzed. The maximum palm kernel oil (PKO) biodiesel yields, obtained at 55 °C, for the KOH and NaOH catalysts were 86.69% and 75.21% at the molar ratio of 6:1. B20BHT combustion showed 4.6% higher brake thermal efficiency (BTE). NOx emission was reduced by 19.4%, compared to the diesel fuel values. DEE resulted in higher CO and HC emissions compared to diesel fuel values by 39.2% and 7.6%, respectively, whereas smoke emission was improved by 11.5%.
