“…Renewable diesel is derived by refining organic oil/animal fat, extracted in a procedure termed as hydro-treatment of fatty acids. In comparison to the glycerin-based esterification reaction of organic oils/animal fats, the diesel produced in this step is known as renewable diesel in order to differentiate it from conventional biodiesel [45]. Sustainable diesel is generally referred to as "green diesel", and can be extracted from fatty acids or vegetable oils using conventional hydro-treatment technology [46].…”

First, second, third, and fourth-generation biofuels are continuously evolving as a promising substitute to petrodiesel catalyzed by energy depletion, economic and environmental considerations. Bio-diesel can be synthesized from various biomass sources, which are commonly divided into FAME and renewable biodiesel. FAME biodiesel is generally produced by the transesterification of vegetable oils and fats while renewable diesel is produced by hydro-deoxygenation of vegetable and waste oils and fats. The different generation, processing technologies and standards for FAME and renewable biodiesel are reviewed. Finally, the life cycle analysis and production cost of conventional and renewable biodiesel are described.

“…As demonstrated by numerous studies [10][11][12][13][14][15][16][17][18][19], an alternative, non-fossil fuel in a CI engine can improve the emission behavior compared to diesel. Therefore, such a fuel blend was investigated under cold conditions with the optimum injector design.…”

This paper deals with the emission optimization of a compression ignition (CI) engine during cold ambient operation. Hence, in the present study, the effect of different injector nozzle geometries and pilot injection strategies, but also the influence of intake swirl, rail pressure, exhaust gas recirculation (EGR) as well as EGR cooling on the emission behavior during cold run are investigated. Therefore, test bed experiments under steady-state cold conditions are conducted on a state-of-the-art CI single cylinder research engine (SCRE) with approximately 0.5 l swept volume representing the typical passenger car (PC) cylinder size. The cold charge air temperature of down to −8 $$^{\circ }\hbox { C}$$ ∘ C and a low engine coolant and lube oil temperature represent a cold run close to reality. For emulating the higher friction of a typical 4-cylinder PC engine during cold run, the indicated mean effective pressure (IMEP) is increased according to a specifically developed equation and the turbocharger main equation is solved permanently to adjust the gas exchange loss. To take account of a potential future tightening of emission legislation, in addition to limited exhaust gas emissions, non-limited emissions such as carbonyls are measured as well. Since alternative fuels are able to make a significant contribution to the defossilisation of transportation, an oxygen-containing fuel, consisting of 100 % renewable blend components (HVO, ethers and alcohols) and fulfilling the EN 590 legislation is investigated under the same cold conditions in addition to the research on conventional diesel fuel.

“…HVO diesel is derived from waste cooking oil or animal fats while GTL diesel is produced from the Fischer-Tropsch process by the conversion of methane-rich gases into longer-chain hydrocarbons (liquid synthetic fuels). GTL and HVO diesels have lower engine out emissions than ULSD [3,4]. Furthermore, the two alternative fuels can be used in CI engines without modifying the existing infrastructure.…”

Heat Release Rate (HRR) analysis is indispensable in engine research. The HRR of Internal Combustion Engines (ICEs) is most sensitive to gamma ( ). The proposed HRR models in literature were largely based on expressed as functions of temperature. However, is depended on temperature as well as the excess air ratio ( ). In this work, an improved HRR model based on ( , ) was used to investigate the combustion behaviour of standard diesel, Gas-to-Liquid (GTL) diesel and Hydrotreated Vegetable Oil (HVO) diesel in a 96 kW, multiple fuel injection, Euro V, Direct Injection (DI) engine. The improved HRR model (Leeds HRR model) was validated for the alternative fuels by comparing the fuel masses predicted by the model to the measured fuel masses. The fuel masses predicted by the Leeds HRR model were also compared to the predictions from four HRR models that were based on ( ). No work has been done in the past to investigate the combustion behaviour of GTL and HVO diesel in a multiple fuel injection, Compression Ignition (CI) engine. This work also featured two novel approximation techniques that were used to estimate the rate of evaporation of the injected fuel from the HRR profiles and the actual SoC from the HRR and fuel burn profiles (for the case of significant heat release bTDC). The overall average error in the predictions of the Leeds HRR model was 4.86% with a standard deviation of 2.39 while the typical error in the other models ranged from 14.66% to 19.99%. The accuracy of the HRR model of CI engines for the HRR analysis of GTL and HVO diesel is therefore, improved by using ( , ). The combustion of HVO diesel was found to be the smoothest of the three fuels due to the narrow distillation range of HVO diesel.
