“…However, the use of ethanol is limited due to the disadvantages of low calorific value and low cetane number 20 . Compared with ethanol, n‐ butanol has a higher carbon content, higher calorific value and cetane number, 21,22 and good mutual solubility with diesel 23,24 . Blending n‐ butanol with biodiesel and diesel as a fuel for diesel engines can both reduce the combustion of fossil fuels and significantly reduce the emissions of pollutants.…”

In this paper, a three‐dimensional simulation model of the engine cylinder is established using commercial simulation software AVL‐Fire, and the accuracy of the model is verified with experimental results. The effects of diesel/biodiesel/n‐butanol blends on diesel engine performance, and combustion and emissions characteristics were investigated by performing simulation operations on the model. The combustion process in the cylinder was simulated for 0%, 5%, 10%, 15%, and 20% of n‐butanol in the fuel mixture. The results showed that at 75% load, the brake thermal efficiency of D95N5, D90N10, D85N15, and D80N20 engines increased by 0.84%, 1.68%, 2.48%, and 3.19%, respectively, and soot emissions decreased by 2.76%, 5.52%, 8.25%, and 10.96%, respectively, compared with D100. However, the brake power of the engine was reduced, the brake ratio fuel consumption increased, and NOx emission increased. In addition, at all loads, soot and CO emissions decrease as the percentage of n‐butanol in the fuel mixture increases.

“…However, FID is not sensitive to unburned oxygenated fuel, aldehydes, and acetaldehydes, which are significant species in the exhaust for alcohol combustion. Several literature studies discuss the relative lower sensitivity of FID analyzer for unburned species with alcohol combustion both with blends of gasoline with methanol [7][8][9][10], ethanol [11][12][13][14], and nbutanol [15,16] as well as neat alcohol operation [17,18]. Accordingly, researchers typically employed alternative measurement methods, such as the Fourier Transform Infrared 01/28/2020 Spectroscopy (FTIR), gas chromatography (GC), and 2,4dinitrophenylhydrazine (DNPH) cartridge/impinger sampling systems to measure the unburned fuel species.…”

Typical automotive emission testing systems usually employ Flame Ionization Detection (FID) analyzers to measure unburned fuel species in the exhaust, but the technique is not suitable for engines operating on alcohol fuels. The FID method is not sensitive to measuring unburned alcohol fuels due to the presence of oxygen bonds in the fuel molecule. Other techniques, such as Fourier Transform Infrared (FTIR), can provide accurate unburned fuel measurements with alcohol fuel. However, these techniques are expensive and are less accessible compared to FID analyzers. In this study, the unburned fuel emissions from the engine exhaust were measured simultaneously with FID and FTIR analyzers, with the engine operating on pure alcohols, which are methanol, ethanol, and n-butanol. While most previous work focuses on stoichiometric airfuel mixtures, a wide range of lean operating conditions between global-λ 1.6 to 2.8 will be tested in this study. Such ultra-lean operation was achievable thanks to the narrow-throat pre-chamber combustion concept with the pre-chamber fueled with methane. The unburned fuel measurements from the two analyzers are compared, and correction factors for each fuel are identified to rectify the FID unburned fuel measurements based on the results provided by the FTIR.

“…The literature contains studies in which their authors point to the possibility of using various fuels for powering diesel engines. These include FAME (in amounts higher than the standard 7% (v/v)) [17], vegetable oils [18], dimethyl ether DME [19], butanol [20], pyrolysis oil [21] or synthetic fuels [22]. Some of these can only be used as a fuel component, while DME and synthetic fuels constitute complete substitutes.…”

Compatibility of Different Automotive Elastomers in Paraffinic Diesel Fuel

et al. 2021

The introduction of new fuels to power internal combustion engines requires testing the compatibility of such fuels with materials commonly used in fuel supply systems. This paper investigates the influence of alternative fuels on the acrylonitrile-butadiene rubber and fluoroelastomer used in the automotive industry. In the study, conventional diesel fuel, its blend with 7% of fatty acid methyl esters and paraffinic diesel fuel produced with the Fisher Tropsch synthesis from natural gas were interacted with the elastomers. The immersion tests were carried out at room temperature (20 °C) for 168 h. The effect was evaluated based on changes in the selected rubber’s volume, mass and hardness. It has been confirmed that the synthetic component without aromatic hydrocarbons had a different effect on the tested rubber than did conventional fuel. In follow-up work, the selected rubbers were also subjected to microscopic observation. The most frequently observed effect was the washing out of the seal protective layer.
