Abstract:Gas exchange instability is an important issue that affects the stability of the linear engine generator (LEG). Fuel injection quantity fluctuation is a potential disturbance factor that induces LEG gas exchange instability. In order to grasp the impact of fuel injection quantity changes on LEG under the action of multi-field coupling the effect of gas exchange stability, a numerical model of the coupling of motion-combustion-gas exchange multiprocessing is constructed, and the calculation method of cyclic ite… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
