“…Meanwhile, the so‐called microexplosion phenomenon (eg, breakup of a droplet into smaller droplets) was observed for all the droplets throughout the linear‐burning phase, as shown in Figure . The remarkable attributes found for all the droplets can further enhance the spray distribution and droplets' breakup rate within the combustion chamber for better combustion, and thus improving the thermal efficiency of the engine …”

“…The single droplet‐combustion experimental setup used in this study is the same as the one described by Ooi et al Experiments were conducted in an enclosed and insulated chamber with viewing windows on 2 opposite sides to allow access for a high‐speed camera and a high‐intensity backlight. A fuel droplet (approximately 60 μL by volume or 1.2 ± 0.1 mm in diameter) was produced and suspended on an end wire of a K‐type thermocouple by using a microsyringe.…”

Summary Graphite oxide (GO) is an important member of the graphene family of carbon nanomaterials with remarkable physical, chemical, and thermal properties. We conducted an experimental investigation on the combustion characteristics of diesel and biodiesel droplets dosed with 0.1% GO. The fuels were tested by a single droplet combustion experiment in which the temporal variation in the burning behavior of a suspended droplet was captured using a high‐speed camera. Numerical analysis of the combustion data suggests that the addition of GO in both fuels resulted in shortened ignition delay (by up to 38.2%), increased burn‐rate constant (by up to 29.4%), lowered peak temperature (by up to 7.8%), and shortened burning period (by up to 11.6%). To illustrate, the burn‐rate constant increased from 0.68 to 0.88 mm2/second, and the burning period reduced from 2.7 to 2.2 seconds when GO was dosed in diesel. By contrast, the ignition delay and peak temperature both decreased from 1.6 to 1.4 seconds and 659 to 611 K, respectively, when GO was added in biodiesel. Our results suggest that the fuel additive–induced benefits could effectively reduce emissions and improve fuel consumption for diesel engine applications.

Metal‐based fuel additives have been promising alternative choice to improve diesel engine performance and emission characteristics. Many studies have been performed on use of metal‐based fuel additives such as magnesium, platinum, titanium, and cerium in diesel engine. Unlike conventional metal‐based additives, Acetylferrocene and Ruthenium polypyridyl complex may be alternative metal‐based additives for diesel. This study intends to investigate performance and emission variations of a diesel engine powered by diesel blended with Acetylferrocene and Ruthenium polypyridyl complex additives. In accordance with this purpose, a single cylinder, direct injection diesel engine was used to test these alternative metal additives. Results showed that Acetylferrocene and Ruthenium polypyridyl complex were effective to improve emission characteristics without causing degradation in performance. CO and Soot emissions were showed decrease up to 40% and 32%, respectively, and the fuel consumption characteristic of engine was improved with additives. © 2019 American Institute of Chemical Engineers Environ Prog, 38:e13146, 2019

Abstract:The enhancement of the physicochemical characteristics of fossil fuel has been the subject of extensive research to achieve better efficiency and reduced emissions. Diesel is one of the fossil fuels that are highly consumed in daily life. This paper focuses on the behavior of a refined diesel fuel when copper oxide nanoparticles are added. The resulting blend of nano-diesel has been analyzed using a four-stroke engine under two loads indicating light vehicles and heavy duty vehicles. The nano-diesel was prepared by the aid of an ultrasonicator and a mechanical homogenizer. A base diesel was taken as a reference to distinguish the effect of the nanoparticles additives. Three different samples with different concentrations are utilized in this study. As a result, the fuel consumption, exhaust temperature, brake power, power losses and engine efficiency have been evaluated and compared to the base diesel in order to demonstrate and access the enhanced performance of the nano-fuel blend. The three concentrations conducted were 100 ppm, 200 ppm and 300 ppm of copper oxide nanoparticles. The results represented that the pure refinery diesel has low exhaust temperatures, high brake power and high efficiency as compared to the commercial diesel supplied from a gas station. In addition, 300 ppm copper oxide nano-diesel showed improvement in engine performances as compared to the other concentrations and pure diesel. In this context, lowest fuel consumption for both passenger cars and heavy duty vehicles was achieved, brake power for passenger cars only was improved and input power showed improvement however, exhaust temperature was the highest as for this fuel.
