The invention relates to an internal-
combustion straight-heating
steam engine which takes fuel as energy and is based on the structure of an internal-
combustion engine. The internal-
combustion straight-heating
steam engine consists of a
crankshaft 1, a connecting rod 2, a cylinder 3, a
piston 4, a sprinkler 5, a heat storage
carburetor 6, a water tank 7, a high-pressure
hydraulic pump 8, a
water filter 9, a return
pipe 10, a conduit
pipe 11, a
water pressure regulator 12, an
exhaust valve 13, a
spark plug 14, an
electrical control assembly 15, a wiring harness 16, an intake valve 17, an oil atomizer 18, an
oil pressure regulator 19, an oil delivery
pipe 20, an oil return pipe 21, a
gasoline filter 22, a high-pressure
oil pump 23, an
oil tank 24 and a cylinder cover 25, and is characterized in that: the sprinkler is arranged on the cylinder cover, the heat storage
carburetor is arranged in the cylinder, and the sprinkler is connected with the
water pressure regulator which is connected with the water tank by the high-pressure
hydraulic pump. In the expansion
stroke, the gas combustion causes the temperature in the heat storage
carburetor to rise, the sprinkler sprays right amount of water into the heat storage carburetor, then the water is vaporized, and the steam drives the
piston to move so as to output
mechanical energy. The internal-combustion straight-heating
steam engine is characterized by high efficiency, energy saving,
environmental protection, and the like.
