“…The optimization results show that RSC uses a wide range of power factors and factors, while CSC uses a wide range of power factors and intrinsic Efficiency to achieve pure and high-power Efficiency. Li et al [24] proposed direct injection using direct injection of highpressure methane. Therefore, we conducted gas injection and combustion experiments with a single-cylinder CI engine with a compression ratio of 15.5.…”

Due to the increase in grounds performance of internal combustion engines, the diesel engine has become dominant forces in the power, propulsion, and energy. For domestic, industrial, and transportation applications, internal combustion engines are the more reliable and misogynist power source. Diesel engines rely on fluid Spritz dynamics for air-fuel mixtures and swirl plays a crucial role in the pattern of air motion as impacts fuel air mixing and combustion. Further-more, older studies have indicated that it affects heat transfer, combustion efficiency, and engine emissions. By varying air inlet pressure, this work demonstrates the presentation and production features of Compression Ignition engines. Using compressor, the inlet pressure of air is manipulated, and when compressed air is sent to engine at different pressures, performance parameters and heat balance sheets are calculated.

“…NG mainly contains methane, and this low-carbon gas fuel has been widely applied in many power devices such as the internal combustion engines for vehicles, ships, and power plants. , Most modern internal combustion engines powered by gas fuels utilize pulsed fuel injection system to realize air–fuel mixture formation, and gas fuel direct injection (DI) is helpful for improving efficiency. Natural gas fuel as one alternative fuel is a promising focus because of its abundant storage, widespread distribution infrastructure, and low cost together with clean-burning qualities, , and the direct-injection compression ignition (DICI) technology benefits the NG engines with high thermal efficiency and low emission. , The direct-injection technology requires high pressure of the gas fuel, and high-pressure gas fuel direct injection is necessary for higher efficiency and output power.

Dual-fuel diesel/natural gas direct-injection engine is promising and highly attractive due to its low-carbon emission and high thermal efficiency, and both high-pressure diesel and natural gas injections are critical for air−fuel mixing. This study presents an optical experimental investigation on the highpressure dual-fuel diesel/methane injection process based on a constant-volume vessel test rig. The results show that the diesel penetration process of the dualfuel injection experiences two stages: Stage I, the diesel tip penetration S diesel , the diesel spray area A diesel , and the diesel spray perimeter C diesel of the dual-fuel injection are smaller than those of the single diesel injection. Stage II, both the diesel and methane continue to penetrate forward, and S diesel , A diesel , and C diesel of the dual-fuel injection become larger than those of the single diesel injection do. The diesel injection pressure causes effect on the dual-fuel spray penetration. The diesel injection pressure directly causes linear influence on the two-stage dual-fuel injection characteristic. As the diesel injection pressure increases, the diesel spray meets the methane jet advancer and the cross point occurs linearly earlier. Furthermore, the dual-fuel injection is asymmetric and the methane gas jet enhances this asymmetry so that the spray cone shifts to the side of the methane gas jet.
