“…Studies on vegetable oils as fuel in diesel engines have been conducted by many researchers . Diesel engines fuelled with vegetable oils result in almost the same power output and slightly lower thermal efficiency. , The main obstructions for commercialization of biodiesel are an elevated cost for its production from nonedible or edible oils . The cost of biodiesel production accounts for 70% of its feedstock and also the rapidly increasing vegetable oil cost in the market. , Fuel with blends of 20–30% vegetable oil with diesel gave better performance over other blend ratios, and this is confirmed by many researchers .…”

Renewable energy research in support of the generously developing choice for diesel fuel automobiles has been concentrated because of environmental causes and hurly burly into petroleum combat. The test has been conducted in a light-duty single cylinder variable compression ratio (VCR) naturally aspirated multifuel research engine. Three input parameters, compression ratio (CR), injection pressure (IP), and injection timing (IT), are taken as input amends. In this study parameters are taken as 16, 17, and 18 for CR and 210 bar, 230 bar, and 250 bar for IP and 21°, 23°, and 25° before top dead center (bTDC) for IT. Experimental trials have been planned via statistical tool like design of experiments (DoE) to outline the resulting output, such as performance and emission. Better performance and lesser exhaust pollution are the desirable output factors by optimizing the injection system and compression ratio parameters by factorial design. The confirmatory tests validated that the models developed using response surface methodology (RSM) are adequate to describe the effects of CR, IP, and IT on the performance and emission characteristics using all test fuels. The error in prediction using RSM is within 5%.

“…Although attention remains focused on blending FAME with the diesel mix, some have begun to blend other types of biofuels, such as hydrotreated vegetable oil (HVO) 11 . Recent claims that HVO is greener than FAME have led to increased traction surrounding the possibility of HVO replacing diesel completely 12 . Hydrotreated vegetable oil is produced from the hydrogenation of vegetable oils such as palm oil, where hydrogen is used to break down large molecules into smaller ones.…”

The trend towards increasing biofuel blending mandates in several countries has raised a sustainability trilemma, especially for biofuels derived from palm oil. This study aims to find the most sustainable hydrogen production technology for the production of hydrogenated vegetable oil (HVO) and biofuel blending. It assesses the sustainability of palm‐oil‐derived biofuel blending of biodiesel (FAME), HVO, and petroleum diesel. There are three hydrogen production options for HVO: steam methane reforming (SMR), biomass gasification (BG), and electrolysis from solar energy (PVELC). The use of any production option depends on a combination of fuel quality standards and the prioritized sustainability considerations. The fuel quality aspects consist of constraints on the quality of the blend based on EURO‐2, EURO‐4, and EURO‐5 fuel standards, while sustainability priorities lead to varying policy preferences involving economic, environmental, and social sustainability considerations. There are two approaches to determine the most sustainable blend: using the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) method and using the sustainability index. The results show that scenarios that favor the economic dimension tend to produce a higher FAME blend, whereas those that prioritize the environment emphasize higher HVO blending with PVELC as the hydrogen production technology. Finally, any scenario that prefers the social aspects tends to produce higher biofuel blending. Overall, to achieve higher sustainability, higher biofuel blending is needed. The policy analysis section concludes that the biofuel policy direction should focus more on combining HVO and FAME so that each can offset the disadvantages of the other. © 2022 Society of Chemical Industry and John Wiley & Sons, Ltd.

“…In such case, these fuels can be classified as second-generation biofuels, not competing with food production [11]. During the production of HVO and FAME natural gas is utilized, however, a comparison of carbon footprints of HVO and FAME indicates HVO as more greenhouse friendly [7].…”

This study investigates combustion and emission characteristics of a contemporary single-cylinder compression ignition engine fuelled with diesel, fatty acid methyl esters (FAME) and hydrotreated vegetable oil (HVO). These two drop-in fuels have an increasing share in automotive supply chains, yet have substantially different physical and auto-ignition properties. HVO has a lower viscosity and higher cetane number, and FAME has contrary characteristics. These parameters heavily affect mixture formation and the following combustion process, causing that the engine pre-optimized to one fuel option can provide deteriorated performance and excess emissions if another sustainable option is applied. To investigate the scale of this problem, injection pressure sweeps were performed around the stock, low NOX and low PM engine calibration utilizing split fuel injection. The results showed that FAME and HVO prefer lower injection pressures than diesel fuel, with the benefits of simultaneous reduction of all emission indicators compared to DF. Additionally, reduction of injection pressure from 80 MPa to 60 MPa for biodiesels at low engine load resulted in improved brake thermal efficiency by 1 percentage point, due to reduced parasitic losses in the common rail system.
