“…In general, there were three methods to control the concentration and flow rate of the air and natural gas mixture in the first generation of NGEs. (1) Under the condition that the flow passage cross section of natural gas remained constant, the mixture concentration was adjusted by controlling the natural gas inlet time. (2) Under the condition of constant natural gas inlet time, the mixture concentration was controlled by changing the area of cross section of natural gas flow passage.…”

“…Stricter and stricter policies and regulations have been applied by governments of many countries due to over 20% pollutant emissions coming from automotive vehicles. Driven by the low cost, abundant resources, and desires to reduce the carbon emissions, it is expected that more natural gas would be put into application of automobiles in near future [1].…”

Review A Review of Development of Natural Gas Engines Lidong Liu 1, Mengli Zhang 1, and Zhengbai Liu 2, * 1 College of Automobile and Traffic Engineering, Liaoning University of Technology, Jinzhou 121001, China 2 School of Innovation and Entrepreneurship, Southern University of Science and Technology, Shenzhen 518055, China * Correspondence: liuzb3@sustech.edu.cn Received: 4 January 2023 Accepted: 22 February 2023 Published: 9 March 2023 Abstract: Natural gas has been successfully applied to the operation of internal combustion engines (ICEs) in various applications including automotive vehicles and generator sets, and is becoming a promising alternative fuel in ICEs due to its advantages such as the excellent knock resistance, stable combustion process, and low pollutant emissions. The operation cost of vehicles using natural gas engines (NGEs) is remarkably reduced, as the price of natural gas is over 50% lower than that of gasoline or diesel fuel. This review describes three stages of the NGEs development followed by discussions of natural gas resources, mechanisms underlying structural design and combustion process of NGEs, as well as different technologies applied in NGEs. The scientific guidance for research and development of NGEs is also provided in this review.

This paper presents a planned heating control strategy applied for a natural gas thermal desorption system for polluted soil to achieve the dynamic adjustment of the heating time and energy consumption. A lumped-parameter model for the proposed system is established to examine effects of the natural gas mass flow rate and the excess air coefficient on the heating performance of the target soil. The control strategy is explored to accomplish the heating process as expected with constant temperature change rate or constant volumetric water content change rate at different phases by adapting the natural gas flow. The results demonstrate that the heating plan can be realized within the scheduled 36 days and the total natural gas consumption can be reduced by 24% (1487 kg) compared to that of the open-loop reference condition, which may be widely applied for other thermal remediation systems of the polluted soil.

“…One of the essential actions for mitigating current climate change risks is to significantly reduce transport sector emissions [1][2][3][4]. As a consequence, over the last few years, an increasing number of researchers have focused on the development of advanced propulsion systems [5]. In particular, powering Internal Combustion engines (ICEs) with gaseous or strong evaporative fuels (like hydrogen, propane or methane gas) may be introduced in the near future and also maintained for a longer period (especially if equipping heavy-duty long-range transport applications) to achieve the aforementioned goal [6].…”

The current ongoing rise in environmental pollution is leading research efforts toward the adoption of propulsion systems powered by gaseous fuels like hydrogen, methane, e-fuels, etc. Although gaseous fuels have been used in several types of propulsion systems, there are still many aspects that can be improved and require further study. For this reason, we considered it important to provide a review of the latest research topics, with a particular focus on the injection process. In advanced engine systems, fuel supply is achieved via enhanced direct injection into the combustion chamber. The latter involves the presence of under-expanded jets. Under-expanded jets are a particular kind of compressible flow. For this reason, the review initially provides a brief physical explanation of them. Next, experimental and numerical CFD investigation techniques are discussed. The last section of this manuscript presents an analysis of the jet’s structure. The injection parameters commonly used are examined; next, the characteristics of the near-nozzle field are reviewed and finally, the far-field turbulent mixing, which strongly affects the air–fuel mixture formation process, is discussed.
