“…Fuel with a higher viscosity will increase the problem of the atomization process and risk damaging the fuel injector. So that it will result in incomplete combustion and reduced engine performance and cause engine damage due to the deposition of solid particles that cannot be burned [13] [14]. The addition of bio additives which results in a decrease in the viscosity value allows the quality of the fogging to be maximized so that the combustion that occurs will be more complete.…”

Octane, heating, and viscosity value are important parameters that affect fuel quality. These parameters are related to combustion process and energy produced and affect vehicle performance. Main fuel is Pertalite with octane number of 90 (RON). The quality of Pertalite can be improved by adding turpentine oil as a bio-additive. This study analyzes effect of adding turpentine oil on these parameters and vehicle performance. Turpentine oil contains oxygenate, so long-term use has a lower risk to the engine. Various composition of turpentine oil for mixture with Pertalite are 0% (PMT 0%), 10% (PMT 10%), 20% (PMT 20%), and 30% (30% PMT) with a total volume of 100 (ml) of each sample mixture. A centrifuge (200 rpm) was used to ensure sample was evenly mixed. Results show addition of turpentine oil increases octane and heating value. The highest octane and heating values were PMT 30% samples, 94.4 (RON), and 39573.1 (KJ/Kg). Meanwhile, the lowest viscosity value was PMT 10%, which was 0.886 cSt. All fuel samples have a viscosity value according to the standard, which is below 1 cSt, so they can be used for testing on vehicles. Vehicle performance test shows that increase in octane and heating value will be followed by an increase in the number of torque and power. PMT 30% produced the highest torque and power numbers, 25.5 Nm (3000 rpm) and 12.10 hp (4000 rpm). An increase in the torque and power is proportional to the increase in specific fuel consumption, 2,377 Kg/Hour.hp (8000 rpm).

“…In addition to the above results, the CR spectral behavior at the various emulsion compositions can be summarized from the spectra using several statistical parameters; from which, necessary comparisons/inferences can be made. In this study, spectral centroid (µ 1 ), root mean square frequency (RMSF), spectral skewness (SS), and spectral kurtosis (K f ) were employed and are defined in Equations ( 4)- (7), respectively.…”

“…Quite unconventionally, this quest to improve fuel quality, reduce emission severity, and minimize costs motivated water emulsification of diesel fuels. Accordingly, these factors also motivated several studies that mostly report experimental investigations of engine performance and exhaust gas emissions under operating conditions of W/D emulsion fuels [6][7][8][9].…”

Diesel engine emissions contribute nearly 30% of greenhouse effects and diverse health and environmental problems. Amidst these problems, it is estimated that there will be a 75% increase in energy demand for transportation by 2040, of which diesel fuel constitutes a major source of energy for transportation. Being a major source of air pollution, efforts are currently being made to curb the pollution spread. The use of water-in-diesel (W/D)-emulsified fuels comes as a readily available (and cost-effective) option with other benefits including engine thermal efficiency, reduced costs, and NOx reduction; nonetheless, the inherent effects—power loss, component wear, corrosion, etc. still pose strong concerns. This study investigates the behavior and damage severity of a common rail (CR) diesel fuel injection system using exploratory and statistical methods under different W/D emulsion conditions and engine speeds. Results reveal that the effect of W/D emulsion fuels on engine operating conditions are reflected in the CR, which provides a reliable avenue for condition monitoring. Also, the effect of W/D emulsion on injection system components-piston, nozzle needle, and ball seat–are presented alongside related discussions.

“…Gel fuel is a type of condensed substance that combines the advantages of solid and liquid fuels [2][3][4]. Research on gel fuels is customarily subdivided into four areas: rheology [5,6], preparation [7,8], transportation and atomization [9] and combustion in rockets and power plants [10,11]. The widespread use of gel fuels in the power industry requires a detailed investigation of the characteristics and patterns of their ignition and combustion processes.…”

A model was developed to research the critical conditions and time characteristics of the ignition of gel fuels in the course of conductive, convective, radiant and mixed heat transfer. MATLAB was used for numerical modeling. Original MATLAB code was established pursuant to the developed mathematical model. For gel fuel ignition at initial temperatures corresponding to cryogenic storage conditions with different heating schemes, a numerical analysis of interconnected processes of heat and mass transfer in the chemical reaction conditions and exothermic and endothermic phase transitions was conducted. The model was tested by comparing the theoretical results with the experimental data. Dependencies were established between the key process characteristic (i.e., the ignition delay time) and the ambient temperature when the following parameters were varied: emissivity, heat emission coefficient, activation energy and pre-exponential factor of the fuel vapor oxidation reaction. The critical values of the main parameters of the energy source were determined. For these values, gel fuel ignition conditions were consistently realized for each heating scheme. The critical heat fluxes necessary and sufficient for the ignition of typical gel fuels were determined.
