Engine generating energy through physical and chemical energy conversions of a compressed gaseous fuel

This invention describes a vehicle engine that uses a special type of fuel, like liquefied petroleum gas. First, the stored liquid fuel is pressurized and then used to spin a turbine, which generates electricity. After this initial energy extraction, the same fuel is then burned in a combustion engine to provide additional power.

Why it matters: Since 2013, advancements in hybrid vehicle technology and sophisticated engine control systems have made integrating electric generators with combustion engines more feasible. Improved fuel system controls for managing liquefied petroleum gas and its phase changes could also make this dual energy extraction more efficient.
