Natural gas combustion in diesel engine

Abstract

The article is devoted to the use of natural gas as an alternative fuel for diesel engines. When operating the diesel engine on natural gas with an additional portion of the diesel fuel are distinctive features of the processes of mixture formation and combustion, there is heterogeneity of the combustible mixture in the cylinder, more fuel evaporation and other aspects of the processes of formation of the fuel-air mixture and its combustion. Consequently, the use of alternative fuels with different chemical composition leads to distinctive indicators of the combustion process. Therefore, for the scientific representation of the real picture of the combustion process in a diesel engine running on natural gas, it is necessary to conduct an indication of its working process and a detailed description of the combustion process.

Comment l’industrie du gaz naturel peut-elle faire progresser les objectifs de double carbone? Une étude de cas de la Chine selon la perspective de la chaîne industrielle

“…Le principal composant du gaz naturel est le méthane, et ses principales sources de pollution sont le soufre et une très petite quantité d'azote (Lopatin, 2020;Zou, Yang et collab., 2018). Les émissions de polluants atmosphériques et de gaz à effet de serre sont moindres par rapport à celles du charbon et du pétrole (Moore et collab., 2014;Zou, Yang et collab., 2018).…”

“…Par rapport aux sources d'énergie fossile traditionnelles, le gaz naturel permet d'économiser plus de 20 % d'énergie et a un taux d'utilisation global de l'énergie de plus de 80 % (Lopatin, 2020;Lv, 2022;Zhou et collab., 2022;Zou, Yang et collab., 2018), ce qui réduit de 1,79 milliard de tonnes les émissions de dioxyde de carbone, de 140 millions de tonnes les émissions de dioxyde de soufre et de 22 milliards de tonnes les émissions de poussière (Gao et collab., 2022;Zheng, 2022). Cela réduit ainsi considérablement les émissions de polluants atmosphériques et contribue à préserver l'atmosphère (Gao et collab., 2022;Zheng, 2022).…”

A Review of Using Natural Gas in Internal Combustion Engines

“…A special intake valve opening technique to enable internal exhaust gas recirculation [IEGR]. The article results were that the use of dual-fuel improves the efficiency of fuel conversion compared to CNG without hydrogen ethanol because of less unburnt hydrocarbon ( HCS ) and carbon monoxide ( CO ) and NOx emissions increased in the case of dual fuel compared to CNG case (da Costa et al, 2019) [6]. A comparison between lean combustion and exhaust gas recirculation in an engine fuel with HCNG was conducted by (Park et al, 2017) [7].…”

“…Using lean burn and EGR strategies increased emissions of CO2 compared to the stoichiometric case without using the dilution strategy. [13] studies a diesel engine fueled with natural gas with diesel fuel enrichment that produces better mixture formation and combustion. The researcher also made a comparative study on the difference between operating diesel engines on natural gas and diesel fuel.…”

Optimization of adiabatic flame temperature of natural gas combustion under different conditions

“…utilized in the transportation sector, steam power plants gas turbines, and so forth. [7][8][9][10] Adiabatic flame temperature (AFT) is defined as the maximum temperature of the products of combustion assuming no heat loss.…”
