Patent ID: 7975485

Claim:
A method for operating integrated heat engine comprising: operating the engine with compound cycle; operating the engine with combined cycle; integrating both compound cycle and combined cycle into single engine body; applying multiple working fluids into single engine body; constructing the engine with compound cylinder structure; combusting fuel inside twin compound cylinders; applying compound combustions inside twin compound cylinders; expanding working fluids inside twin compound cylinders; applying compound expansions inside twin compound cylinders; applying staged-combustion inside twin compound cylinders; injecting working fluids into engine cylinders; transferring working fluids between twin compound cylinders; acquiring mechanical power from multiple kinds of power strokes driven by expansions of multiple working fluids; supercharging the engine by piston operation inside compound cylinders; storing supercharged working fluid into intermediate storage container; intercooling supercharged working fluid by evaporative intercooler; spraying fuel into evaporative intercooler; evaporating fuel inside evaporative intercooler; integrating catalytic metal meshes into engine cylinders; covering piston crowns with insulation materials; covering engine body with insulation materials; recovering exhaust heat energy with heat exchanger; utilizing exhaust energy to actuate engine valves; adopting pneumatic hybrid braking energy regeneration; adopting compressed air as working fluid for energy regeneration; working under multiple stage air compressor mode; working under multiple stage compressed air engine mode; cooling compressed air under air compressor mode; heating compressed air under compressed air engine mode; storing heat energy into vacuum insulated thermos tank under air compressor mode; storing pneumatic energy into compressed air reservoir under air compressor mode; releasing stored heat energy for energy regeneration under compressed air engine mode; releasing stored pneumatic energy for energy regeneration under compressed air engine mode; charging heat energy through “plug-in” to household electrical power source; and charging pneumatic energy through “plug-in” to household electrical power source.
