Abstract:
1. 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 block; applying multiple working fluids into single engine block; constructing the engine with compound cylinder structure; constructing the engine with piston-in-cylinder structure; combusting fossil fuel inside triple compound cylinders; applying compound combustions inside triple compound cylinders; expanding working fluids inside triple compound cylinders; applying compound expansions inside triple compound cylinders; applying staged-combustion inside triple compound cylinders; injecting working fluids into engine cylinders; combining different working fluids inside triple compound cylinders; transferring combined working fluids between cylinders of triple compound cylinders; acquiring mechanical power from multiple kinds of power strokes driven by expansions of multiple working fluids; sharing one common secondary cylinder between two primary cylinders; operating the engine with greater than unity overall Lambda valve; combusting fossil fuel near stoichiometric point inside primary cylinders; oxidizing combined working fluids with greater than unity Lambda valve inside triple compound cylinders; integrating catalytic metal meshes into engine cylinders; covering piston crowns with insulation materials; covering engine block 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.
