“…Lower sulfur and aromatics content, as well as higher flash point, good oxygen presence, higher cetane number, and better lubricity are some of the advantages that vegetable oils offer when used as diesel fuel. Their disadvantages include very high viscosity, higher pour point, lower heating value and lower volatility (3,4) . Transesterification of vegetable oils with chemical catalysts is the standard method for producing biodiesel.…”

Objectives:The aim of this study is to produce biodiesel from crude Mesua ferrea oil and to determine the influence of different operating characteristics, especially catalyst content, methanol to oil molar ratio and reaction temperature on the evaluation of biodiesel yield. Likewise, to assess the physicochemical properties of Mesua ferrea oil biodiesel for diesel engine applications. Methods: Prior to biodiesel production, the crude oil was degummed, bleached and deodorized to remove free fatty acids. Subsequently, the Mesua ferrea oil was converted into biodiesel using the basic transesterification process.The catalyst concentration was varied as 1%, 1.5% and 1.75%, respectively, while the molar ratios were 6:1, 8:1 and 10:1, and the reaction temperatures of 50 o C, 60 o C, and 70 o C were considered. Finally, the physicochemical properties were estimated with the aid of ASTM standards. Findings: The individual conversion efficiencies of MOBD (Mesua ferrea oil biodiesel) were 98.8%, 98.6%, and 98.1%, respectively. In addition, KOCH 3 catalyst has shown better yield of biodiesel than other catalysts. The better yield of biodiesel is found at 8:1, 1.5%, and 60 o C and the individual yields are 98.8%, 98.6% and 98.1%, respectively. Novelty: The influence of different operating parameters on the evaluation of optimal biodiesel yield when using hydroxide and methoxide-based catalysts is a new approach. The biodiesel yield of the methoxide-based (NaOCH 3 and KOCH 3 ) catalyst was higher than that of the hydroxide (NaOH and KOH) catalyst. Similarly, the cetane number of the biodiesel is increased, which is a primary fuel property during combustion in diesel engines.

“…One of the most important and widely used techniques for converting fossil fuels into useful energy is the use of diesel engines. Diesel engines have many practical applications in the business world, from cars to ships to trains 1–4 . Transportation, power generation, and waste incineration are often selected for preliminary estimates because of their significant contribution to greenhouse gas emissions.…”

The objective of the present study is to evaluate the performance, combustion, and emission characteristics of a compression-ignition engine using hydrogen-compressed natural gas (HCNG)-enriched Kusum seed biodiesel blend (KSOBD20). The flow rate of HCNG was set at 5, 10, and 15 liters per minute (lpm), and the injection pressure was varied in the range of 180-240 bar. Brake thermal efficiency (BTE) and brake-specific fuel consumption (BSFC) were improved when HCNG was added to the KSOBD20. Combustion characteristics, namely, cylinder pressure (CP) and net heat release rate (NHRR), were also improved. Emissions of carbon monoxide (CO), hydrocarbons (HC), and smoke were also reduced, with the exception of nitrogen oxides (NO x ). The higher injection pressure (240 bar) had a positive effect on operating characteristics. At an injection pressure of 240 bar, for KSOB20 + 15 lpm HCNG, the highest BTE and the lowest BSFC were found to be 32.09% and 0.227 kg/kWh, respectively. Also, the CP and NHRR were 69.34 bar and 66.04 J/deg. CO, HC, and smoke levels were finally reduced to 0.013%, 47 ppm, and 9%, respectively, with increased NO x levels of 1623 ppm. For optimum results in terms of engine characteristics, the fuel combination
