“…Distinctions of the mass burn fraction the ignition timing of −20.8° CA~−14.2° CA were minor; however, they were for the range of −11.1° CA~−8.3° CA. Mass burn fraction profiles were retarded by late ignition for a spark ignition engine fuelled with syngas over the equiv of 0.85 [53]. Heat release rates determined the in-cylinder pressure evolutions, further affecting the engine efficiency and power output.…”

The application of hydrogen fuel in ORP engines makes the engine power density much higher than that of a reciprocating engine. This paper investigated the impacts of combustion characteristics, energy loss, and NOx emissions of a hydrogen-fuelled ORP engine by ignition timing over various equivalence ratios using a simulation approach based on FLUENT code without considering experiments. The simulations were conducted under the equivalence ratio of 0.5~0.9 and ignition timing of −20.8~8.3 °CA before top dead centre (TDC). The engine was operated under 1000 RPM and wide-open throttle condition which was around the maximum engine torque. The results indicated that significant early ignition of the ORP engine restrained the flame development in combustion chambers due to the special relative positions of ignition systems to combustion chambers. In-cylinder pressure evolutions were insensitive to early ignition. The start of combustion was the earliest over the ignition timing of −17.3 °CA for individual equivalence ratios; the correlations of the combustion durations and equivalence ratios were dependent on the ignition timing. Combustion durations were less sensitive to equivalence ratios in the ignition timing range of −14.2~−11.1 °CA before TDC. The minimum and maximum heat release rates were 15 J·(°CA)−1 and 22 J·(°CA)−1 over the equivalence ratios of 0.5 and 0.9, respectively. Indicated thermal efficiency was higher than 41% for early ignition scenarios, and it was significantly affected by late ignition. Energy loss by cylinder walls and exhaust was in the range of 10%~16% and 42%~58% of the total fuel energy, respectively. The impacts of equivalence ratios on NOx emission factors were affected by ignition timing.

“…Carbon dioxide accounts for 95% of it, while hydrogen and other trace compounds add up to 3% . It is possible to produce biogas from a combination of commercial and agricultural waste, animal manure, straw, and domestic sewage, and it contains roughly 50–70% methane, 25–50% CO 2 , and 1–5% hydrogen and is an environmentally sustainable fuel for vehicles. − Biogas can be substitute for natural gas and is used in place of natural gas. The findings demonstrate that the physical and chemical properties of gasoline and biogas are compared.…”

Gasoline is a liquid composed of hydrocarbons, refined from crude petroleum, and characterized by a boiling point. It is difficult to regularly refine these oils, and their scarcity in natural resources makes it problematic to refine them. Gasoline engines produce fewer toxic emissions, like NO x , CO, and CO 2 . On the basis of economical and natural concerns, gasoline can be put back by many alternative fuels. It can be powered by alternative energy sources, like hydrogen, natural gas, ethanol, acetylene, propane, biogas, etc. The performance of these types of fuels in an internal combustion engine is very charming and appropriate for nature. Hydrogen is sustainable, and the amount of energy necessary to create hydrogen is small. Hydrogen engines are more prominent at approximately 30% compared to gasoline engines in terms of direct injection. Ethanol causes 80% less CO emissions after it has been properly blended with gasoline. Natural gas fueling stations are expanding in popularity. After the natural gas percentage is increased in the fuel, high efficiency is achieved at a sustainable performance in the 0.7−0.9 equivalent ratio. (G + 1000 g/h acetylene) has a higher brake thermal efficiency (G + 500 g/ h acetylene). These vehicles, after all, have seen considerable increases in terms of fuel economy, total performance, and substantially reduced emission standards. This study aims to compare various alternative fuels with gasoline by analyzing their availability, engine tests, toxic element emissions, price, etc. Furthermore, a selection criterion for alternative fuel is given in various measuring scales that will be helpful for choosing alternative fuels because fossil fuels are running out.

“…For example, Xie et al [17] used ignition and EGR to control load of a spark-ignition engine fueled with methanol. Arroyo et al [18] used a group of experimental tests to study the effect of ignition timing and supercharging on a gasoline engine fueled with synthetic gases extracted from biogas. Yousufuddin and Masood [19] studied the effect of ignition timing and compression ratio on the performance of a hydrogenethanol fueled engine.…”
