“…Rapeseed methyl ester is a biofuel with high viscosity and density, which can be prepared from biological sources such as vegetable oils (rapeseed oil). Esters of vegetable oils such as rapeseed oil, soybean oil, and cottonseed oil are considered as renewable alternative solutions for diesel oils [26][27][28][29]. Methyl esters are produced from corresponding vegetable oils through esterification process [9,16,[26][27][28][29].…”

Methyl esters are produced from corresponding vegetable oils through esterification process [9,16,[26][27][28][29]. The addition of a mixture of diglyme (C 6 H 14 O 3 ) and butyl diglyme (C 12 H 26 O 3 ) to "base" fuel DI1 at different blending ratios produced two oxygenated diesel fuels, namely GLY10 (89.8 mass-% DI110.2 mass-% glymes) and GLY30 (68.7 mass-% DI1-1.3 mass-% glymes) with 3% and 9% oxygen content, respectively.…”

“…Klyus [24] investigated the impact of various biofuels on CI engine technology. Buyukkaya [25] analyzed the impact of biodiesel content and type on DI diesel engine combustion characteristics and pollutant emissions and Allocca et al [26] performed measurements in a quiescent combustion chamber and in a EURO5 CI engine using conventional diesel oils and RME. Imran et al [27] thoroughly examined the impact of RME on CI engine performance and emissions under various engine speeds and loads and demonstrated the positive influence of this biofuel on CI engine soot reduction.…”

An experimental investigation is performed in a single-cylinder direct-injection (DI) diesel engine using city diesel oil called DI1 and two blends of DI1 with a mixture of glycol ethers. The addition of glycol ethers to fuel DI1 produced oxygenated fuels GLY10 (10.2 mass-% glycol ethers) and GLY30 (31.3 mass-% glycol ethers) with 3% and 9% oxygen content, respectively. The addition of biofuel rapeseed methyl ester (RME) to fuel DI1 produced oxygenated blend RME30 (31.2 mass-% RME) with 3% oxygen content. Engine tests were performed with the four fuels in the DI diesel engine at 2500 RPM and at 20%, 40%, 60%, and 80% of full load. The experimental diesel engine was equipped with devices for recording cylinder pressure, injection pressure, and top dead center (TDC) position and also it was equipped with exhaust gas analyzers for measuring soot, NO, CO, and HC emissions. A MATLAB 2014 code was developed for analyzing recorded cylinder pressure, injection pressure, and TDC position data for all obtained engine cycles and for calculating the main engine performance parameters. The assessment of the experimental results showed that glycol ethers have more beneficial impact on soot and NO emissions compared to RME, whereas RME have less detrimental impact on engine performance parameters compared to glycol ethers.

“…The flame lift-off length (FLoL) and the length based on the first appearance of soot (SLoL) are longer for RME. Allocca et al [20] characterized the spatial fuel distribution, mixture formation and the vaporization-combustion processes of the petrodiesel and RME in a non-evaporative spray chamber and an optically accessible engine. The observation indicated that diesel fuel evaporates more efficiently than RME, which affect the gaseous emissions; in fact, HC and CO for RME are slightly higher than diesel.…”

HVO, RME, and Diesel Fuel Combustion in an Optically Accessible Compression Ignition Engine

et al. 2019

The current paper investigates the spray and combustion characteristics of Hydrotreated Vegetable Oil (HVO), petrol diesel (EN590), blends of HVO with petrol diesel (70% EN590 and 30% HVO) and Rapeseed oil Methyl Esters (RME) in an optically accessible compression ignition engine. Mie scattering and natural luminosity imaging are employed to measure the liquid spray and combustion behaviors. The spray and combustion processes are divided into four stages based on optical imaging. The morphology and quantitative analysis based on imaging provides a method for visualizing the incylinder spray and combustion behavior with four test fuels. The ignition delay and combustion characteristics detected from optical measurements are compared to those determined from cylinder pressure. The results show that the ignition delay of HVO and RME occurs earlier and the flame propagation at the premixed combustion stage proceeds faster compared to EN590 and HVO30. The spray and combustion characteristics of HVO30 are similar to EN590. However, ignition occurs earlier for HVO30 due to the higher CN. Comparison of the HVO and RME shows that there is a marginal difference in the ignition delay for these two fuels. However, the combustion duration of RME is shorter than that of HVO.

“…The oil produced from the plants alone can be used to fuel compression ignition engines. Due to the stringent emission limits imposed on modern engines, precision injection systems must be used that are, unfortunately, very sensitive to fuel quality [Allocca et al 2014], [Szlachta 2002]. Due to the differing physical properties that change the fuel injection parameters, use of crude oils is problematic, especially in engines with common rail injection systems.…”

The first part of this paper presents an evaluation of the rheology of three fuel types for compression ignition engines, i.e. a conventional fuel grade and two biofuel grades, each with rapeseed oil. The analysis completed for this work has uncovered that a clear relationships exist between fuel temperature, density and viscosity. The second part of this paper is a determination of stream parameters of the analyzed fuels injected into a specially designed metering chamber via a common rail injection system. The third and last part of this paper is an evaluation of the microstructure of rapeseed stream by division of the stream into contours of different light reflectivity values corresponding to different fuel concentrations within the stream.
