Multidimensional analysis of the impact of motion variation on exergetic performance in a free piston linear hydrogen engine

International journal of hydrogen energy, 2020
Linear engine is a promising new energy conversion device which supports variable stroke (or compression ratio) operation for thermal optimization. Previous studies have shown that hydrogen fuel is well adapted to the new engine due to fast combustion ...

Study on methanol-hydrogen engine in extended-range electric vehicles

International Journal of Engine Research
The demand for clean and efficient new vehicle models is steadily increasing. Methanol-hydrogen engines use methanol as the main fuel and can recover the heat from engine exhaust to dissociate part of methanol into hydrogen-rich syngas.

Effect of variable stroke on fuel combustion and heat release of a free piston linear hydrogen engine

International journal of hydrogen energy, 2019
Variable stroke (or compression ratio) has been expected as a potential technology for optimizing engine combustion all the time. The free piston motion of linear engines introduced by its unconstrained dynamics is well suited for this expectation.

The effect of motion on fuel diffusion and mixture preparation of a free-piston linear hydrogen engine

International journal of hydrogen energy, 2019
The most notable difference between linear hydrogen engine (LHE) and conventional crank hydrogen engine (CHE) is that the former supports variable motion operation for combustion optimizing.
