“…in charging time of the battery, charging stations, safety issues, cruising range, distance traveled per charging, and maintenance problem of EV is importantly unveiled (Kuhe & Aliyu 2017;Kattela et al 2018;Ravikumar et al (2018a,b); Zhen et al 2019). Therefore, the invention and utilization of renewable energy have a good perspective on vehicles (Gao et al 2007;Yang et al 2009;Kolokotronis et al 2010;Dernotte et al 2010;Potter et al 2012;Anand et al 2012).…”

“…Currently, environmental pollution and emissions from automobile vehicles are the most important concern. The various countries are paying more attention to minimize the exhaust emission such as carbon monoxide (CO), nitrogen oxides (NOx), and hydrocarbon (HC) from an automotive vehicle by adopting new inventions in the design and development of IC engines (Sissine 2007;Demirbas 2009;Hoang & Le 2017;Kattela et al 2018;Zhen et al 2019). Many research results on IC engines reveal that without enhancing the physical, chemical, and thermal properties of fuels it is difficult to achieve greater thermal efficiency, brake power, fuel economy, and reduction in CO, NOx, and HC emissions even after modifying the internal combustion engines.…”

Renewable energy called normal-butanol is a possible alternative fuel for automobile vehicles like some other possible fuel such as compressed natural gas (CNG), liquid petroleum gas (LPG), ethanol, and methanol. Bio-butanol or normal-butanol is also a meritable energy source to substitute for regular fossil fuels. The normal-butanol has recently started to use as a possible substitute fuel to regular fuels for internal combustion engines to attain eco-friendly and capital benefits. As compared to regular energy sources in internal combustion engines, normal-butanol has some benefits, so it shows the potential to decrease tailpipe emission andan increase in positive network delivery. The current work carried out to investigate the performance and emission characteristics of dual spark plug ignition engine fuelled with normal-butanol as additive fuel by adopting 10:1 and 10.5:1compression ratios. The experimental results reveal that when compared between 10:1 and 10.5:1 compression ratios, brake power (BP) is increased by 3.5% and 3.2% for normal-Butanol 35 (nB35) blend and energy efficiency increased by 2.72% and 2.14% for nB35 blend at a part and full load for 10.5:1 compression ratio. The n-butanol create a greater impact on tailpipe emissions that the carbon monoxide (CO) decreased by 32%, 29%, and hydrocarbon (HC) reduced by 2.38% and 2.22% for nB35 blend at a part and full load condition respectively. The experimental results on dual spark ignition engine using n-butanol as additive fuel by varying compression ratioreveals that n-butanol can be a suitable replacement energy source for the automobile sector in the nearest future.

“…Swirl movement of air is the movement around the circumference of the piston bowl geometry; as it moves, the increase in velocity leads to better air-fuel mixing to result in incomplete combustion and reduced emissions. The standard hemispherical PBG is modi ed into the split (toroidal) and re-entrant type [11][12][13][14]. Jaichandar et al [15].…”

The present investigation is carried out on biodiesel practicability over the existing non-renewable fuel due to its environmental dilapidation effect and oil crisis. Biodiesel was extracted from crude oil by transesterification, and its properties have been compared with those of neat diesel according to ASTM standards. Then, the blends of biodiesel are prepared for experimental analysis. Experimental results from our previous research study, the best blend was optimized. Then, the standard CI engine with Hemispherical Piston Bowl Geometry (HPBG) is modified to Toroidal or Split type Piston Bowl Geometry (TPBG) and Re-Entrant Piston Bowl Geometry (RPBG). Experimental works were carried out for preheated optimized blend, neat diesel with modified Piston Bowl Geometries. The engine characteristics results were compared with these altered conditions. The modified PBG with preheated biodiesel blend resulted in better Performance and Combustion characteristics. The preheated biodiesel blends indicated significant depletion in the emission of harmful particulate matter such as CO, NOx, and unburnt Hydrocarbons.

“…Diesel engines (CI) are superior to gasoline engines due to their higher power, efficiency and fuel economy. However, diesel engines impose environmental concerns due to higher NO x and soot emissions 1‐3 . In order to overcome this is problem, the scientific research has mainly focused on the optimization of engine parameters.…”

To achieve emission standard norms and higher fuel efficiency conversion are the main concerns in diesel engines. The single parametric study approach might not attain the optimal combustion characteristics. In order to overcome this issue, multi objective study has been carried out to achieve the higher performance and simultaneously reduction of emissions. The main objective of present article is identifying the optimum set of the engine parameters for diesel fuel, which gives better performance and emissions. Numerical analysis was carried out by using CONVERGE CFD software. Numerical analysis were carried out by varying the Compression Ratio (CR) (12–16.5), Start of Injection (SOI) (0–25° bTDC), Fuel Injection Pressure (FIP) (500–1,400), and Exhaust Gas Recirculation (EGR) (0–40%). Response surface methodology was used for optimization. The parameters are optimized for minimizing the NOx, soot, and ISFC by using the Response Surface Methodology (RSM). Regression equations were developed for the responses such as ISFC, NOx, and soot. It was observed that the interaction effects also play a major role in determining the performance and emission characteristics of the engine. The optimum combination of operating parameters was found to be CR 14.55, SOI 16.29° bTDC, FIP 855 bar, and EGR 26.15% with a composite desirability of 0.94. The corresponding NOx and soot emissions are reduced by 40.3% and 52.38%, respectively, and a marginal reduction in the ISFC is accomplished. Mixture homogeneity (TFDI) was improved 27% for optimum case compared to baseline configuration.
