Problems solved by technology

[0002] In order to improve the power, thermal efficiency and decontamination requirements of the piston reciprocating internal combustion engine, the current method is exhaust gas turbocharging or additional mechanism supercharging; exhaust gas turbocharging is difficult to meet the needs of various working conditions, and the transient response is lagging, so it is necessary to add Auxiliary facilities are resolved, increasing engine complexity and manufacturing costs
The mechanical supercharging outside the machine also increases the complexity and consumes additional power. The above measures still lack the control of the volume and temperature of the pressurized air. Therefore, although some results have been achieved, it is not ideal. , the largest number of small and medium-sized engines are difficult to popularize

specific Embodiment approach 1

[0012] Specific implementation mode 1: as figure 1 As shown: the application "a rack and pinion mechanism" (application number 200710147446.7) is used for power transmission. The upper horizontal connection part of the rack frame in this mechanism [6] is connected to the engine cylinder piston [7], and the lower horizontal connection part is made booster cylinder piston [5], so the two pistons are synchronous and have the same stroke; the diameter of the booster cylinder piston [5] is more than 2 times the diameter of the starting piston [7], forming an ultra-high booster mechanism, so that the power of the engine is The power of the engine cylinder is more than 5 times when it is not boosted (the specific value depends on the design requirements), the booster cylinder is made under the power output shaft (gear shaft), and the four sides are continuously cast on the body with transverse partitions (as shown in Figure 2.1 ).

specific Embodiment approach 2

[0020] Specific implementation mode 2: as Figure 6 Shown: frame [30] upper end connects piston [7] (piston lower mouth makes piston skirt, is connected on the frame [30] with screw), crank shaft [31] passes through frame [30] front and rear middle opening, crank pin [33] is placed in the frame [30] and rotates in the frame [30]. The lower end transverse connection part of framework [30] is made booster cylinder piston [5], the structure and arrangement of booster cylinder [16] and cover plate [20] and other parts are identical with embodiment 1, show and illustrate this in the figure omitted.

Abstract

The invention discloses a working substance flowing system of a piston reciprocating internal combustion engine and regulation and control setting thereof. An upper end of a frame moving up and down along the rotation of a power shaft is connected with an engine cylinder piston [7]; the lower end of the frame is made into a pressure cylinder piston [5]; an air inlet pipe[14], an air inlet check valve[2] and an air compression check valve[3] are arranged on a bottom cover plate of the pressure cylinder; air sucked from the air inlet pipe[14] by the pressure cylinder is sprayed by water mist for intercooling in compression; compressed air is stored in an air storage channel, tangentially supplied to an air inlet[10] of an engine cylinder sleeve; a rod head of the air compression check valve[3] is connected with the compressed air regulating and controlling device. An exhaust port [12] of the engine cylinder is arranged in the rear side of the cylinder top; a pressurized air bypass channel tightly pressed on the lower side of a flashboard-type exhaust valve [21] and an air suction check valve [22] of the upper side of a vent-pipe inlet cool an exhaust system and exhaust air and have the effects of both decontamination and preventing an exhaust gas turbine from surging. The supercharging mechanism has compact structure, indirect transmission, stable pressurization and cooling function; the working substance flowing system is provided with the regulating and controlling device with optimized performance and is convenient to the actualization of a small and medium sized engine.
