Verification of ignition energy time distribution control for a diluted combustion engine
Nihon Kikai Gakkai ronbunshu, 2021 Several high energy ignitions have been proposed to improve ignition performance of diluted combustion recently. One of the major issues in the high energy ignition systems is heat generation of an ignition coil due to increase of power consumption. This

Numerical Study and Experimental Validation of Minimum Ignition Energy for Microwave Spark Ignition [PDF]
IEEE Access, 2021 Microwave plasma ignition has the potential for energy savings and emission reductions, and the minimum ignition energy (MIE) and the lean limit can be determined by microwave spark plugs (MSPs) under the same microwave power. To predict the relationship among electric field intensity (EFI), equivalence ratio (φ) and MIE, a physical model of ...

Energy Injection for Fast Ignition [PDF]
Plasma and Fusion Research, 2009 In the fast ignition concept, assembled fuel is ignited through a separate high intensity laser pulse. Fast Ignition targets facilitate this ignition using a reentrant cone. It provides clear access through the overlaying coronal plasma, and controls the laser plasma interaction to optimize hot-electron production and transport into the compressed ...

Energy Estimation and Testing Verification on Ignition of a Torch Ignition System
Journal of Physics: Conference Series, 2022 Abstract The torch type electric ignition system is a desirable choice for reusable liquid vehicle engine. It is generally believed that the ignition and start-up process of engine are crucial and high-risk. However, due to the complexity of combustion experiments, the ignition and start-up process can be efficiently analysed from the ...
