... Abstract Liquefied petroleum gas (LPG) is a promising diesel fuel alternative for heavy-duty vehicle applications due to its CO 2 reduction potential, high knock resistance, easy liquefication capability, and lower fuel cost. Direct injection (DI) of liquid-phase LPG has emerged as a promising...

... conditions inside the chamber. The injected fuel jet generates turbulence in the vessel and forms a turbulent heterogeneous fuel air mixture in the vessel, similar to that in a compressed natural gas (CNG) direct injection engine. The fuel air mixture is ignited by centrally located electrodes at a given...
