In the present invention, low-pressure fluid passage in the shell of so-called Jet injector can have reducing and expansion district, so-called reducing and expansion district refers to the region that the section area of low-pressure fluid passage changes, and described shell can be set to Venturi tube or shunting island, and high voltage power fluid tip can be set to Laval nozzle.
In the present invention, the fluid that the motive fluid injection pipe of described Jet injector sprays can be oxygenant, reducing agent or other fluid.
In the present invention, so-called " working medium envelope " refers to the wall in the space holding gas working medium, the wall in the space of the accommodation gas working medium be such as made up of piston, cylinder and cylinder head, or the wall in the space of the accommodation gas working medium of communicating passage formation.
In the present invention, so-called " the working medium enveloping space " refers to the space of the accommodation gas working medium that working medium envelope is formed.
In the present invention, according to the known technology of heat energy and dynamic field, necessary parts, unit or system etc. should be set in the place of necessity.
Beneficial effect of the present invention is as follows:
Working medium internal combustion heater of the present invention can make the fluid chemical field (indistinct merging, chemical reaction occurred) of the fluid and the described working medium enveloping space being ejected into the described working medium enveloping space (space in such as reciprocal passage) be in steady state, thus can occur to stablize chemical reaction (abundant mixed combustion), and then stable operation.
