Fig. 2 is the sectional view along A-A line among Fig. 1.

Fig. 3 is the sectional view of combustion gas mixing firing chamber second embodiment of the utility model tape guide blade.

Fig. 4 is the sectional view along B-B line among Fig. 3.

Fig. 5 be guide vane be located at Fig. 3 in structure sectional view during diverse location.

Adopting shown in Fig. 1 is cold in the rotary valve, the structure sectional view of the secondary cylinder 1 of regenerative heat type internal-combustion engine and master cylinders 14, and the entrance point of combustion gas mixing firing chamber 9 is communicated with the heat outlet of being controlled by rotary valve 43, and outlet end is communicated with master cylinders 14 through connecting passage 13.Secondary cylinder 1 among the figure has been connected by rotary valve with master cylinders 14, gas distribution piston 2 in the secondary cylinder by backheat pressurized air row to firing chamber 9.Because set is the combustion gas mixing firing chamber that has guide vane, the guide vane 16 of some quantity is arranged in the circular entrance point that is evenly arranged in the firing chamber.For forming rotating vortex, guide vane will form corresponding angle of inclination with the air-flow that flows into, here, because flowing into the air-flow of firing chamber entrance point is axially to pass through guide vane, each guide vane on the angle of inclination with the air-flow shape that axially flows into the suitable angle about at 45, so that allow the pressurized air that flows through form rotating vortex, thereby the fuel oil that helps being sprayed with oil sprayer 19 better carries out mixed combustion.In the given structure of Fig. 1, each guide vane 16 is to be connected on the internal face 11 of gasket rings 17 by its outside, and each guide vane is the basic axis 22 that points to the firing chamber on the arranged radially direction.Be located at the entrance point of firing chamber by guide vane 16 and its gasket rings 17 of making one, be in the top of combustion chamber insert 12.For preventing that set guide vane 16 from influencing the injection process of oil sprayer 19, the inner side edge of guide vane be that the axis 22 with the firing chamber keeps suitable distance and its inner side edge also outward-dipping corresponding angle, make the guide vane that is circular layout can reserve the space that a mist of oil with certain angle of flare that is sprayed with oil sprayer 19 adapts at the shaft core position place.

Because secondary cylinder 1 relative master cylinders 14 is inclination several angles, oil sprayer is installed for convenience, as shown in Figure 2, allow oil sprayer 19 and firing chamber relative master cylinders 14 such as 9 grades on being in same axis 22 certain angle that also all tilted, after being provided with like this, the work done combustion gas of flowing out from the firing chamber is tangentially to enter master cylinders 14 through connecting passage 13, in master cylinders, also form certain rotation eddy current, to help allowing the work done combustion gas that enters master cylinders continue to finish the mixed combustion process in later stage.

In cold in shown in Fig. 3, the regenerative heat type internal-combustion engine, the heat outlet 3 of secondary cylinder 1 is by plunger valve 5 controls, plunger valve among the figure is in the top lift position, and gas distribution piston 2 is just pressed to combustion gas mixing firing chamber 9 to the pressurized air after the backheat through the plunger valve of opening in the secondary cylinder.In Fig. 3 structure, each guide vane 16 of firing chamber 9 is to be connected on the annular bottom surface 7 of flange platform 6 of plunger valve by its top, this with Fig. 1 in guide vane be connected on the internal face of firing chamber entrance point by its outer side be different.Rise at plunger valve 5, and after the flange platform 6 of its underpart leaves sealing seat 8, owing to the air-flow that comes from secondary cylinder is that radial flow is through the flange platform basically, if the suitable angle of guide vane thereon 16 about the air-flow shape of crossing with radial flow on the arranged radially direction is at 45, as shown in Figure 4, allow the pressurized air that flows through guide vane form rotating vortex, thereby help and the fuel oil better mixing.Guide vane 16 is basically perpendicular to the annular bottom surface 7 of flange platform on the axially-aligned direction.The bottom surface 7 and sealing seat 8 formed distances (shown in the position of lifting valve among Fig. 3) of its flange platform entered the firing chamber when guide vane 16 was wanted suitably to be in the top lift position greater than plunger valve in axial length so that allow pressurized air can both flow through guide vane 16.For this reason, the outer side of guide vane 16 also will be tried one's best near the internal face 11 of firing chamber entrance point.For not blocking the mist of oil that oil sprayer 19 is sprayed, the base of guide vane 16 for the angle of flare that adapts to mist of oil also outward-dipping several angle.The glow plug 21 of lighting fuel mixture is located on the sidewall of firing chamber 9, as shown in phantom in Figure 4.When guide vane is not located on the plunger valve, also can be shown in Fig. 5 structure, adopt guide vane 16 and gasket rings 17 are made one, be located at the bottom of sealing seat 8, but allow the flange platform 6 of guide vane and plunger valve 5 reserve certain distance, then contact with guide vane to prevent that plunger valve is worn.
