One-dimensional simulation of two stroke hydrogen direct injection linear generator free-piston engine

Developing one-dimensional (1D) simulation of two stroke hydrogen direct injection linear generator free-piston engine (2-stroke H2-DI LGFPE) is a low cost approach and it can avoid errors. A 1D simulation 2-stroke H2-DI LGFPE has been developed using GT-POWER software. The performance parameters of...
