“…Since the methodology described in this manuscript requires crank angle resolved pressure traces from MCC and PC, both chambers are separately equipped with cylinder pressure transducers. The measurement infrastructure that was used to measure the experimental data for the development and evaluation of the methodology in this manuscript is similar to the one described in Tilz et al 44…”

Significant improvements in the power density and efficiency of lean-burn large gas-engines with a prechamber and their high flexibility in meeting fluctuating power requirements illustrate the potential for using these engines in stationary power generation and in the transportation sector. Since these engines have comparatively low CO2 and NOx-emissions, they are seen as a promising solution to meet stricter emission standards. However, current combustion concepts for these engines must be enhanced to improve their performance and emission behavior; simulation methods play a major role in this process. It is critical to know and understand the fundamental processes and their relationships in the prechamber and main combustion chamber; conducting detailed analyses makes this possible. Zero-dimensional methods are suitable for these analyses. Due to their shorter calculation times, they allow extensive parameter variations to be investigated. Common methods in this area are limited to calculating performance and emission related values only in the main combustion chamber. Since a considerable share of NOx-emissions from high-performance lean-burn gas-engines arise in the prechamber, it is imperative to conduct a separate thermodynamic analysis of the prechamber and its interaction with the main combustion chamber. This paper presents a zero-dimensional method with which NOx-emissions from the prechamber can be calculated separately from the emissions of the main combustion chamber. To this end, it is necessary to conduct thermodynamic analyses of both the chambers and to consider their interaction. The measurement data for development and validation of this method is provided by tests on a single-cylinder engine with separate cylinder-pressure indication for both the chambers. Based on the results of the analyses, it can be determined to what extent each of the two systems is involved in the formation of nitrogen-oxides. With knowledge of the origin of NOx-emissions, measures may be enacted that reduce total NOx-emissions.

“…Except for the pilot commercial engines from manufacturers, such gas engine test benches are still lacking, especially the large-bore gas engine. Single-cylinder engines have been developed for simplification and can be used for steady-state studies in laboratories [150][151][152]. They are primarily charged by the supercharger or compressors directly, rather than utilizing a real turbocharger due to the exhaust gas pulsation.…”

Liquefied natural gas (LNG) is widely regarded as the midterm solution toward zero-carbon transportation at sea. However, further applications of gas engines are challenging due to their weak dynamic load performance. Therefore, the comprehension of and improvements in the dynamic performance of gas-engine-based power systems are necessary and urgent. A detailed review of research on mechanisms, modeling, and optimization is indispensable to summarize current studies and solutions. Developments in engine air-path systems and power system load control have been summarized and compared. Mechanism studies and modeling methods for engine dynamic performance were investigated and concluded considering the trade-off between precision and simulation cost. Beyond existing studies, this review provides insights into the challenges and potential pathways for future applications in decarbonization and energy diversification. For further utilization of clean fuels, like ammonia and hydrogen, the need for advanced air–fuel ratio control becomes apparent. These measures should be grounded in a deep understanding of current gas engines and the combustion characteristics of new fuels. Additionally, the inherent low inertia feature of electric power systems, and consequently the weak dynamic performance when adopting renewable energies, must be considered and studied to ensure system reliability and safety during transient conditions.

“…This essay is going to talk about the advantages and disadvantages, efficiency and other parts to compare spark-ignition engine and electric motor. Spark ignition engine is a type of internal combustion engine in which the air-fuel mixture is ignited using a spark from the spark plug [1]. Now, More and more electric vehicles appear in many countries, it seems better than traditional car (sparkignition engine car/ petrol car).…”

There are lots of differences between traditional engines and alternatives. For example, most of petrol car and electric vehicles have lots of differences. The author will talk about the difference between spark-ignition engine and electric motor (advantages and disadvantages) briefly, and this essay will explain them in a few parts carefully. People will consider of the efficiency of cars, fuel source and other different properties that spark-ignition engine and electric motor have. In efficiency, the author will talk about how to calculate the efficiency of Spark-ignition engine and how to calculate the efficiency of electric motor. in fuel source and emission, the author also will analysis the benefits that electric can do and the Spark-ignition engine cannot do, the environmental problems health problems and resource limited are all important. This essay will explain the difference between Spark-ignition engine and electric motor deeper in the following page.
