JPH0392515A - Engine with cylinder having intake and exhaust holes - Google Patents

Abstract

PURPOSE:To perform smooth intake and exhaust of an engine with a simple structure by disposing a cylindrical component (valve) for free rotation situated to cross the intake and exhaust ports and having a through hole in the direction of its diameter. CONSTITUTION:Cylindrical valve members (a) and (b) for free rotation and each having a through hole in the direction of its diameter are disposed to cross intake and exhaust ports connected respectively to an intake manifold 1 and an exhaust manifold 2. These valve members (a) and (b) are interlocked with a rotating crankshaft and a timing belt and others and rotated. In the suction stroke, the hole of the intake valve member (a) is made to communicate with a cylinder (3) to intake mixture into the combustion chamber. In the exhaust stroke, the hole of the exhaust valve member (b) is made to communicate the cylinder (3) to discharge exhaust gas out of the combustion chamber.

Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to an engine that performs intake and exhaust without using valves, camshafts, valve springs, etc. of a 4-cycle engine. using. To explain based on the diagram, Figure 1 Intake valve (A) and exhaust valve (B)
In order to move the engine up and down, a camshaft (c), valve hook (2), valve spring (e), etc. were required, making the engine larger and increasing costs.

Another drawback is that the valve moves up and down, so there is a lot of loss compared to rotational movement, and when the mixture is sucked into the cylinder, it hits the bulk of the valve before being sucked into the cylinder, so it is not drawn in smoothly and is not combusted. The present invention was devised to eliminate this drawback, and this can be explained with reference to the drawings in Figure 2. An inhalation component (a) that combines a thick prismatic column and a thin cylindrical column with the same center. Exhaust parts (b), suction parts made of a combination of thin cylinders and balls (C), exhaust parts (d)
), the thick cylindrical part (he), (g) and the spherical part (chi),
A hole is made in (ri) and air is inhaled and exhausted through that hole.

A part with only cylinders works the same way, but I wanted to reduce the weight as much as possible, so I created a part that combines a thick cylinder and 11 cylinders (a). (b) Or it is a part that combines a thin cylinder and a sphere (C). 'I think (d) is better. This part will work if it is rotated clockwise or counterclockwise in the same direction, but in the explanation, it will be rotated clockwise when facing the figure. Also, the number of the thick cylindrical parts with holes {he) and (}) and the ball parts (ch) and (ri) are the same as the number of air points in the engine, and the four parts in Figures 2 and 3 are two-cylinder parts. It is used for

(a) of the four figures in Figure 3. (b) is a front view of part 7'j which combines a thick cylinder and a thin cylinder, (C) and (d
) is a front view of a part that combines a thin cylinder and a sphere. I will explain how each of these parts works, but the part that combines a thick cylinder and a thin cylinder and the part that combines a thin cylinder and a sphere have the same role, and the cross section of the hole that I will explain from now on is the same. Therefore, I will explain the parts for intake (a) and exhaust (b), which are parts that combine cylinders.

Figure 4 is a cross-sectional view explaining how to use the intake (a) and exhaust (b). ■ is a diagram showing which part of the perforated part is involved in suction, compression, combustion, and exhaust.The method of division is to divide the cross-sectional circle into 8 equal parts so that the same work is located in front. The suction part (a) connects the suction part with a hole, and the exhaust part (a)
For b), connect the exhaust part with a hole.

Also, there are various possible shapes for this hole, as shown in ■.
In the explanation, we will use a straight line.

Next, we will explain how it is used in combination with the cylinder (nu), intake manifold (ru), exhaust manifold (wo), etc. in Figure 5 and below.

Figure 5 Intake Parts that are removed by the timing belt (a).
(b) shows that when the intake valve (a) is in the position shown in the figure, the hole connects the intake manifold (L) and the cylinder (N), so the air-fuel mixture is negatively affected by the lowering of the piston (W). The pressure draws it into the cylinder.

At this time, the exhaust hole (b) is covered by the wall of the cylinder (nu), so gas will not enter through the exhaust gas.

Figure 6 Compression The air-fuel mixture sucked into the cylinder (N) is compressed as the piston (W) rises, but at this time, both the intake (a) and exhaust (b) are in the positions shown in the diagram. Since it is blocked by the wall of the cylinder (nu), the air-fuel mixture does not escape and is compressed normally. Figure 7 Combustion The compressed air-fuel mixture burns and expands because the spark plug (power) produces a spark.

At this time, the intake (a) and exhaust (b) holes are in the positions shown in the diagram, and each hole is covered by the wall of the cylinder (nu), so the air-fuel mixture does not escape and combustion occurs normally.

Figure 8 Exhaust The exhaust gas generated by combustion is exhausted as the piston (wa) rises again, but at this time the intake port (a) is blocked by the wall of the cylinder (nu). Exhaust gas does not enter or exit, but for exhaust (b
) is located in the position shown in the diagram, so exhaust is exhausted through the hole that connects the cylinder (nu) and the exhaust manifold (wo).

The above is the equipment of this part, and this is repeated.In addition, the rotation speed of the camshaft in conventional engines was 1/2 of the engine rotation speed, but in this engine, four processes are performed at 172 rotations, so the intake The rotational speed for (a) and exhaust (b) is 174 of the engine rotational speed.

Figure 9 Also, for this intake at 1/4 of the engine speed (a)
One way to rotate the exhaust (b) is to use a timing belt (ta) to rotate a crank gear (re) and a gear (y) that has four times the number of teeth as the crank gear (re).

Figure 10 The size of the holes in this part is 1/8 of the circumference of the cross section, but the shapes of the holes in the horizontal part that hang over the top of the cylinder (N) are as follows: Except for the problem of strength, you can think of something like the one shown in the figure.

Since the present invention has the structure described above, it has fewer parts than conventional 4-cycle engines, so the engine can be smaller and costs can be reduced.
