The utilization of biodiesel‐diesel blends in compression ignition (CI) engines are a viable option for the current energy crises. But due to better combustion features of biodiesel‐diesel blends leading to high NOx release from engine exhaust hinders the use of such blends. Usually all of the harmful exhaust emissions like HC and CO reduces marginally, except nitrogen oxides at higher compression ratios with biodiesel blended fuel. The present paper focuses on the study of variation of compression ratio and use of NiO nanoparticles in neem biodiesel‐diesel mixture (NB25) at different braking loads. A total of four test fuels of NB25 blend were prepared having nickel oxides at different concentration levels of 25, 50, 75, and 100 ppm. The current findings reveal that the use of 75 ppm of NiO in NB25 blend reduces the amount of thermal NOx by 6.2% compared to the absence of nanoparticles. Also, the performance parameters such as brake thermal efficiency improved by 2.9% and brake specific fuel consumption reduced by 1.8%. The presence of 75 ppm of NiO in NB25 not only shows best performance and also lower harmful emission.

“…Biodiesel is an environmentally friendly, renewable fuel which can be used in any compression ignition engine to substitute diesel fuel. Chemically, biodiesel contains a mixture of methyl esters with long-chain fatty acids, and is typically derived from nontoxic biological resources, such as vegetable oils [35][36][37][38][39], animal fats [40][41][42][43][44][45][46], or even cooking oils [47][48][49][50]. While many recent works analyzed the effects of biodiesel on the injection process, spray formation, and combustion [51][52][53][54][55][56], this section will emphasize the potential of different biofuel blends in reducing the noise and chemical pollutions of ICEs.…”

Performance Enhancement of Internal Combustion Engines through Vibration Control: State of the Art and Challenges

et al. 2019

View full text Add to dashboard Cite

Internal combustion engines (ICEs) are the primary source of power generation in today’s driving vehicles. They convert the chemical energy of the fuel into the mechanical energy which is used to drive the vehicle. In this process of energy conversion, several parameters cause the engine to vibrate, which significantly deteriorate the efficiency and service life of the engine. The present study aims to gather all the recent works conducted to reduce and isolate engine vibration, before transmitting to other vehicle parts such as drive shafts and chassis. For this purpose, a background history of the ICEs, as well as the parameters associated with their vibration, will be introduced. The body of the paper is divided into three main parts: First, a brief summary of the vibration theory in fault detection of ICEs is provided. Then, vibration reduction using various mechanisms and engine modifications is reviewed. Next, the effect of using different biofuels and fuel additives, such as alcohols and hydrogen, is discussed. Finally, the paper ends with a conclusion, summarizing the most recent methods and approaches that studied the vibration and noise in the ICEs.

“…In one of the relatively recent research work (Ranjan et al, 2018), synthesized magnesia nanoparticles were dispersed in 20 to 50 PPM into three different WCO biodiesel-diesel blend (B10, B20 and B100) to investigate the cold flow properties, functional, exhaust emittent, and combustion characteristics. 30 PPM concentrated fuel samples showed refinement in the cold flow properties.…”

“…Hence from all the literature works, we are evident that the scattering of nanoparticles in fuels can enhance the functional attributes and diminish the emission characteristics of the engines. However, with very minimal works reported on the magnesia nanoparticles that possess excellent thermal properties than other metal oxide particles and in addition to the latest work by Ranjan et al (Ranjan et al, 2018), the waste cooking oil biodiesel contains very high unsaturated fatty acids with the existence of more double and triple bonds in the form of linoleic and linolenic acids. The presence of such bonds leads to lesser oxidation stability which makes it undesirable as a fuel for diesel engine, as they are unsafe during storage, contains lesser heating value, is corrosive in nature, in addition to higher specific fuel consumption.…”

This research article intends to discuss on the role and effects of dispersing solution combustion derived magnesia nanoflakes (~17 nm) within the biodiesel-diesel blends and pure diesel termed as nanofuels, in order to investigate the functional and pollutant emissions of a single-cylinder, electrically loaded, water-cooled diesel engine. The fuels focussed in this study are a blend of palm oil biodiesel and regular diesel dispersed with 50 ppm magnesia nanoflakes, and a pure diesel dispersed with 50 ppm magnesia nanoflakes. These fuels are compared with regular diesel which is considered as the base reference fuel, as well as with the biodiesel-diesel blend. From the experimental measurements, we inferred that the fuel density, viscous nature, and calorific value enhanced with the addition of nanoflakes. As for the engine performance attributes, the brake specific fuel consumption (BSFC) is lessened by 3.08% and 2.88% for particle dispersed biodiesel-diesel blend and particle dispersed diesel, respectively, whereas the brake thermal efficiency (BTE) enhances by 5.04% for particle dispersed biodiesel-diesel blend and 2.74% for particle dispersed diesel. With reference to emission, the unburnt hydrocarbon (UHC), white damp (CO), particulate exhaust or smoke, and the nitrogen oxides (NOx) are reduced by 9.51%, 18.71%, 13.64%, and 5.63%, respectively for particle dispersed biodiesel-diesel blend and 10.35%, 16.54%, 13.64%, 19.47%, and 4.70%, respectively for particle dispersed diesel.
