Abstract

PURPOSE:To prevent an outflow of jetted air, by forming a partition between a flow inlet of air and a flow outlet of combustion gas in a combustion chamber of a gear internal-combustion engine in which an even number of at least four operative gears are annularly arranged and meshed to one another. CONSTITUTION:Six operative gears are annularly arranged and supported to an operative gear case 7 so as to be meshed with one another. (The principal part is shown in thd drawing). A heat insulating base metal 18 is embedded to a location at a face-to-face position to an externally faced meshing point Go in the rear wall face of a combustion block 14, and a spherical combustion chamber 20 is formed between the base metal and the combustion block 14. To prevent jetted air from immediately flowing out to the outside of the chamber 20, a partition 63 is formed between a flow inlet 61 of air and a flow outlet 62 of combustion gas in the chamber 20. Further existence of the partition can surely mix fuel with air, and an air excess factor is decreased while an output of an engine can be increased.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a completely novel combustion chamber for a gear internal combustion engine that extracts power directly from rotational motion.

In a conventional simple spherical combustion chamber, the air injected into the combustion chamber does not sufficiently mix with the injected fuel and combust, but often short-circuits and flows out to the combustion gas outlet, increasing the excess air ratio and reducing the engine output. It is decreasing.

Therefore, in order to solve the above-mentioned problems, the present invention forms a partition between the air inlet and the combustion gas outlet in the combustion chamber to short-circuit the injected air and prevent it from flowing out.

Hereinafter, the wooden F3A will be described in detail based on a specific embodiment shown in the accompanying drawings. 6 operating gears f+1 (21

Further, the meshing point is the intersection of the straight line connecting the centers (0) between the operating gears and the reference pitch circle (pc). A small gear (8) is carved on the shaft end of every other working gear m (al (51), and this small gear (8) is replaced by an annular working gear i11 [2

1. In front of the outward meshing point (Go), for example, on the rear wall of the combustion block (14) at the position shown in Figure 3, there is an air supply port (A).
The combustion chamber (+91) is opened and communicated with the compressed air passage (G).

Although FIG. 3 shows a total of two air supply ports (A), it is also possible to use only one air supply port (A) if necessary.

The combustion block (14) is provided with an air-fuel mixture compression gear pump (c) (c) (c) which is arranged near the central main shaft (9) and driven by the central main shaft (9).
C) (C) (A) is communicated with the air intake port (5) opened on the side of the combustion block (14) through the air passage (C), and a needle valve (2) is installed in the middle of the air passage (C). Fuel passage c! Opens at 4. The governor 01) fitted to the tip of the central main shaft (9) is always urged forward by a coil spring), and the governor cover ■ is placed in front of the combustion block (14) and covers the governor 01), etc. Align the head of the needle valve (A), which is urged forward by a coil spring, with the middle part of the lever ■ whose base end is pivoted, and place the tip of the lever ■ against the back side of the governor I3). bring it into contact.

When the rotation of the central main shaft (9) increases, the governor 0υ moves backward on the central main shaft (9) as the rotation speed increases, and moves the needle valve @ backward via the lever ■ to open the fuel passage (7). The fuel flow path at the opening of the air passage (c) is narrowed, resulting in less fuel supply. In this way, a mixture of air and fuel is formed by driving the gear pumps (c) (c) (c) while adjusting the amount of fuel relative to air with the needle valve (-1 compressed mixture passage (7) is supplied to the combustion chamber (19) (Ql). The compressed mixture passage (7) is equipped with a pressure regulating valve near the combustion chamber Q9) (20) (2υ) to prevent the combustion gas from flowing back to the gear pump (c) (c) (a) side. (
C) (C) is pressure fed against the set pressure of the pressure regulating valve (B).

In addition, the gear pump (c) (c) (c) compresses air,
Therefore, fuel is conveyed, and the amount of fuel supplied is adjusted by a needle valve (A). Also, the combustion chamber (19)
In order to ignite the compressed air-fuel mixture injected into the air-fuel mixture, the glow plug Cll59460 Th is placed so as to face just in front of the opening of the compressed air-fuel mixture passage α. The compressed air-fuel mixture supplied by the gear pump (C) (C) (E) against the set pressure of the pressure regulating valve (B) is constantly pumped into the combustion chamber (+91 (2o)

62) The nearby bulkhead (63) is made high and the center part is made low to direct the air injected from the inlet (61) to the distant outlet (12)) so that it flows diagonally inside the combustion chamber (191F20) (12)). It is also possible to promote the mixing of the air and fuel by letting it flow through the combustion chamber Qqj (20) (2η) and retaining it for a relatively long period of time.

The present invention provides a gear internal combustion engine in which an even number of operating gears of four or more are arranged in an annular manner and mesh with each other, between an air inlet and a combustion gas outlet in a combustion chamber. Because the partition wall is formed in the air, the injected air will not short-circuit and immediately flow out from the outlet.In addition, the injected air and compressed air-fuel mixture collide with the red-hot partition wall and are heated, promoting vaporization and combustion. encourage Furthermore, due to the presence of the partition wall, air and fuel f4
This ensures that the air is mixed properly, lowering the excess air ratio and increasing engine output.
