“…The BSFC of the fuel samples increased with increasing FIP up to 220 bar, then declined at 240 bar FIP, as shown in the graph. This is because the fuel‐air mixture is better atomized and evaporates at greater 220 bar pressure 20 …”

“…At 240 bar, EGT of diesel and B20 are 380.08 and 392.71°C respectively. Additionally, the combustion process is enhanced with higher injection pressure due to increased fuel atomization and air‐fuel mixing, which results in complete combustion and lowers EGT 20 . When compared to diesel at 240 bar, B20A25 exhibited EGT of 357°C which is 9.1% and 6.1% lower than diesel and B20.…”

Alternative fuels have drawn a lot of interest as oil and gas sources have depleted and environmental concerns have grown. An alternative fuel being researched as a potential replacement for fossil fuels is biodiesel. A 5.2 KW, 4-stroke, single-cylinder diesel engine's Performance, combustion, and emission characteristics were evaluated in this study at 1500 rpm with various fuel injection pressures (180, 200, 220, and 240 bar). B20 (80 percent diesel and 20 percent mahua biodiesel) was created by blending mahua oil-based biodiesel with plain diesel at a 20/80 ratio. Al 2 O 3 nanoparticles were then added at four different quantities, including 25, 50, 75, and 100 ppm. It is found that BTE was improved by 6.1% and BSFC was reduced by 2.5% for B20A25over diesel at the FIP of 220 bar. In-cylinder pressure was higher and HRR was raised by 7.2% for B20A25compared to diesel at 180 bar. CO emission was reduced by 39% in B20A25 when compared to biodiesel blend at 180 bar. When compared to diesel at 180 bar, B20A25's HC and CO2 emissions were reduced by 7.5% and 4.5%, respectively. Smoke for B20A25 at 240 bar was 3.6 percent lower than diesel. Maximum NOx emissions reduction was seen when Al 2 O 3 nanoparticles were added to the blend at 220 bar FIP.

Dependence on nonrenewable fuels continues to a great extent today. Overuse of fossil fuels has brought along various environmental problems. In order to reduce such problems, compressed air engines have developed significantly during the last 20 years. Compressed air engines are environment-friendly engines that do not use fossil fuel and achieve expansion using compressed air. It is of great importance for engine efficiency to decrease friction losses of piston engines. There are not many studies in the literature focusing on friction manner of piston ring liner parts of compressed air engines with a piston. In this article, the transformation of a four-stroke gasoline engine with 388 cm3 displacement into a compressed air engine has been carried out and the friction manner between piston cylinder liner has been modeled with the help of GT-SUITE program using in-cylinder pressure-cylinder volume (P-V) data obtained from different engine loads under operating pressure of 12 bar and geometrical size of the engine. It has been determined according to the results of the simulation that asperity friction losses have not changed significantly in top dead center and bottom dead center regions due to low testing speed, and hydrodynamic power losses have occurred in the middle of the course. Lack of combustion reactions in such engines has resulted in compression leakages and unavailability of a quality oil film layer. Since there are no combustion reactions, the eccentric movement of the pistons of the compressed air engines is changed by the lubricating oil, engine speed, compression leaks, and viscosity parameters.

“…They also experienced similar results for CO, HC, and smoke (except NOx) emission, with all blends suggesting that B20 fuel was the optimum blend. Rajan et al [13] evaluated the performance of diesel engines using biodiesel at various injection pressures and reported lower levels of exhaust emissions except for NOx at higher Ips (injection pressure). Ravichandran et al [14] investigated the engine performance by employing a corn oil methyl ester mixture, which produced greater NOx emissions while lowering other pollutants when compared to diesel.…”

The objective of this research work is to evaluate the performance, combustion, and exhaust emissions of a variable compression ratio diesel engine utilizing diesel 25% rubber seed biodiesel mixture (B25) blended with 25 ppm and 50 ppm of alumina nanoparticle running with different operating conditions. An ultrasonicator was used to make uniform dispersion of alumina (Al) nanoparticles in the diesel–biodiesel mixture. Biodiesel mixture blended with nanoparticles has physicochemical characteristics that are comparable to ASTM (American Society for Testing and Materials) D6751 limitations. The results revealed that the B25 exhibited a lower cylinder peak pressure and lower HRR (heat release rate) than diesel at maximum power. BTE (brake thermal efficiency) of B25 is 2.2% lower than diesel, whereas BSFC of B25 is increased by 6% in contrast to diesel. Emissions of HC (hydrocarbon), CO (carbon monoxide), and smoke for B25 were diminished, while emissions of NOx (nitrogen oxide) were higher at maximum power. Further, the combustion and performance of diesel engine were improved with the inclusion of alumina nanoparticles to biodiesel blends. In comparison to B25, BTE of B25 with 50% alumina nanoparticles (B25Al50) mixture was enhanced by 4.8%, and the BSFC was diminished by 8.5%, while HC, CO, and smoke were also diminished by 36%, 20%, and 44%, respectively. At peak load, the maximum cylinder pressure and HRR of B25 were improved by 4.2% and 6.7%, respectively, with the presence of 50% alumina nanoparticles in a biodiesel blend (B25Al50).
