“…These results are in agreement with various reported researches in which the reduction of HC was attributed to the high oxygen content in biodiesel that leads to complete combustion. 34,35,67,74 The maximum concentrations of HC emission are 64 (B5), 63 (B10), 62 (B15), 61 (B20), and 65 ppm (B0), respectively, indicating that this value declines as the concentration of CMKOME increases. On average, the HC in the exhaust gas was found to decrease by 2.07, 4.2, 6.24, and 8.32% while using the CMKO-FAME blend with B5, B10, B15, and B20, respectively.…”

Utilization of agricultural waste such as nonedible seed oil for the synthesis of biodiesel via catalytic transesterification is one of the effective ways for the partial replacement of petroleum-based fuels in the area of renewable energy development and is beneficial to CO, CO 2 , and unburned hydrocarbon (HC) emission reduction to the environment. In this regard, the current study investigates the synthesis of fatty acid methyl esters (FAMEs) from Croton macrostachyus kernel oil by considering parameter interaction and optimization to maximize the yield of fatty acid methyl esters (FAMEs). The response surface methodology–central composite design (RSM-CCD) was applied to optimize the C. macrostachyus fatty acid methyl ester (CMKO-FAME) synthesis process by varying the process parameters such as reaction time (1–2 h), molar ratio (6:1–12:1), and catalyst loading (1–2 wt %). The optimum conditions for the transesterification of C. macrostachyus kernel oil (CMKO) were found to be a methanol to oil ratio of 11.98:1, catalyst loading of 1.03 wt %, and reaction time of 2 h, resulting in the conversion of 95.03 wt % C. macrostachyus kernel oil into its mono FAMEs. The fuel properties of CMKO and its FAMEs were determined based on ASTM D6751 and EN 14214 standards. Further, the CMKO and its FAMEs were characterized using Fourier transform infrared (FT-IR), gas chromatography–mass spectrometry (GC–MS), and nuclear magnetic resonance spectroscopy (NMR). The fatty acid composition of CMKO was myristic acid (1.36%), palmitic acid (11.35%), stearic acid (5.11%), oleic acid (18.64%), gadoleic acid (0.34%), linoleic acid (49.084%), and linolenic acid (14.1%). The purity of the produced methyl esters was determined by 1 H NMR and found to be 95.52%, which was quite in good agreement with the experimentally observed yield of 95.39 wt %. The produced CMKO-FAME was blended with diesel fuel at various ratios (B5, B10, B15, and B20) to evaluate the engine performance and emission characteristics in a diesel engine. The engine brake thermal efficiency is lower, the brake-specific fuel consumption (BSFC) using CMKO-FAME blends is higher, and the temperature of exhaust gas emitted after combustion also increased as compared to diesel fuel. Similarly, using produced FAME blends, the emission emitted such as HC, NOx, and CO is reduced. However, the engine fueled with the produced FAME blends increased the level of CO 2 into the atmosphere when compared to diesel fuel. The performance and emission characteristics of diesel engine result show that the blend of CMKO-FAME and diesel can be used as a fuel in a diesel engine without any modification of the engine.

“…The mix derived from Punnai has a greater ignition pressure and temperature, as well as a shorter ID; additionally, BTE, peak HRR, and power output are equivalent and similar to that of normal diesel (Kshirsagar and Anand 2017). Reformulation of biodiesel fuel compositions has been investigated in certain research as a strategy to reduce increasing NOx emissions (Venkatesan et al 2021). When exhaust gases are recirculated, a portion of the fresh air is supplied with CO 2 from the exhaust gas (Vallapudi et al 2018).…”

Pollution from diesel engines affects negatively the environment. As a result, there is a worldwide concern about reducing the pollutants emitted by diesel engines. In comparison to diesel fuel, biodiesel combustion produces reduced carbon monoxide (CO2) and unburned hydrocarbon (UHC) emissions, but higher nitrogen oxides (NOx) emissions. The current study is to investigate the thermal and chemical effect of exhaust gas recirculation (EGR) on features of a diesel engine for environmental sustainability. The punnai oil was produced from kernels of punnai seeds and transesterified in two phases using alcohol with the existence of a catalyst. The higher viscosity of punnai oil biodiesel is diluted by mixing it with diesel fuel. Our previous investigation indicated that neat punnai oil biodiesel is a potential fuel; however, the findings showed that the addition of diesel is necessary to obtain acceptable engine performance. In this study, punnai oil biodiesel was mixed at a rate of 20% with diesel (B20) and run in a diesel engine with varied EGR rates under five different engine loads. This combined impact enhanced the maximum heat release rate (HRR) and maximum combustion pressure, according to the findings. The premixed burning fractions were commonly higher at all engine loads, whereas the diffusion combustion fractions were lower. When the centre of the HRR changed toward the top dead centre (TDC), combustion durations remained rather constant. The experimental results revealed B20 blend at 10% EGR flow rate produced 6.57% lower BTE, 37.04% higher BSEC, 2.47% higher EGT, 5.13% lower CO, 31.11% higher CO2, 3.13% higher UHC, 8.36% lower NOx and 4% higher smoke opacity when compared with diesel in a standard diesel engine.

“…In recent years, with the increasing retention of internal combustion engines (ICE), pollutant emissions from ICE have already caused considerable damage to the atmospheric environment. Compared with other types of ICE, diesel engines are widely used in various fields such as agriculture, transportation, and industry because of their advantages in reliability and fuel economy. , However, gaseous emissions such as NO x and HC, and particulate emissions mainly composed of soot and unburned carbonaceous compounds are inevitably generated due to inhomogeneous mixture concentration and temperature distribution. , Among them, NO x has a significant impact on the atmospheric chemistry and climate. NO x in the atmosphere can be oxidized to HNO 3 and then deposited as acid rain, which will adversely affect drinking water, soil, and biodiversity. , The particles produced by diesel engines can easily penetrate into the respiratory tract and affect human health.…”

It is of great significance to improve the performance of diesel engines by adjusting the intake components and their distribution. In this work, various proportions of exhaust gas recirculation (EGR) gas and oxygen (O 2 ) have been introduced to the intake charge of a diesel engine and the effects of different intake components and stratification conditions on pollutant emissions, especially for particles, have been explored. The results show that the introduction of O 2 into the intake charge is beneficial to alleviate the deterioration of particles and hydrocarbon (HC) emissions caused by high EGR rates. Compared with the pure air intake condition, the introduction of moderate O 2 at high EGR rate conditions can simultaneously reduce nitrogen oxides (NO x ) and particles, when the intake oxygen content (IOC) is 0.2 and the EGR rate is 20%, the NO x and particles are reduced by 45.66% and 66.49%, respectively. It is worth noting that different intake components have a significant impact on the particle size distribution (PSD) of diesel engines. In addition, the in-cylinder O 2 concentration distribution formed by the stratified intake is advantageous for further improving the combined effect of NO x , particles and HC emissions relative to the homogeneous intake. At a condition of 0.2 IOC and 20% EGR rate, the NO x , particles, and HC emissions are about 8.8%, 14.3%, and 26% lower than that of intake components nonstratification, respectively.
