給装置１こ関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention utilizes negative pressure in the cylinder to supply air-fuel mixture to the cylinder, an intake passage that supplies air or air-fuel mixture to the cylinder, and a supercharger that simultaneously pressurizes the air or air-fuel mixture to the cylinder. One of the two is a supercharging passage forcibly supplying the supercharging device (this is related to the next supercharging device).

。Conventionally, internal combustion engine supercharging systems generally have one supercharger disposed in a single intake passage. However, in such a system, the entire amount of intake air must be supplied from one supercharger, leading to an increase in the size of the supercharger. In other words, for example, if a four-stroke engine is used as the base, one cycle of the engine [total engine exhaust ff1]
A supercharger with a large air supply capacity such as vX1cX supercharging ratio C-charging efficiency during natural intake is required.

。The primary purpose of the present invention is to eliminate such inconveniences, but as the prior art,
No. 8-17927 As shown in Fig. 8-17927, when the intake passage that communicates with the combustion chamber through the intake valve merges with the supercharging passage in the middle, the camshaft for the compression valve at this junction f. In order to selectively open the intake passage and the supercharging passage by interposing a rotor valve that switches in conjunction with each other, the first half of the intake stroke is passed through the intake passage to depressurize the intake passage. When I'i air is supplied into the cylinder, f
During the second half of the intake stroke, the pressure is increased through the supercharging passage.
There is one strainer so that this air can be supplied into the cylinder. However, the lever is 1 [ψ gas:, 1 filtration/supercharger E to supply E in the cylinder'? There is no need for 1°, so it is relatively small. Is it possible to obtain a strong supercharging effect using 8 amounts of supercharging?If a low-return valve as described in U is installed, the structure surrounding the valve train J4 fi'J and the intake valve 17J will be changed. It has the disadvantage of being ``J'', ``I#'', and there is no reason to use it.

It is set up. The intake passage 3 absorbs the air mixture A, which is generated by the air sucked from the air cleaner 5 and passes through the vaporizer 6, and the negative pressure inside the cylinder 2, which is generated as a result of the piston's descent. Utilize the cylinder 2 to supply one cylinder 1. This is a normal one that is constructed in such a way that the intake manifold 7 carries the air-fuel mixture A generated in the carburetor 5 into each cylinder 2 in the direction of γ6, and this It has an intake boat 9 that connects the terminal end of the intake manifold 7 with each cylinder 2 through an intake valve 8.
After the branch part 10 of this intake passage 3, for example, each end of the intake manifold 7 and each intake boat 9,
Connect the check valves 11 with the first... respectively. I am intervening. Each check valve 11 has a structure called a reed valve, and only the air-fuel mixture A flows toward the cylinder 2 7:
One step has been taken to allow P to pass. -10,000, supercharging passage 4
The air sucked from the +3jJ air cleaner 4 is pressurized by a supercharger 121 such as a small air pump, and the pressurized air B is passed through the check valve 11 and 01■ in the intake passage 3. 1 point 11 between ... and 0 ■ intake valve 8...
``It is configured so that it can supply 1 part to 1 part.
Specifically, pressurized air B7 (discharged from the supercharger 12)/guiding main passage section 13, and this main passage section 1
The pressurized air B in the air intake boat 9 is distributed through a branch passage section 14 in the middle of each intake boat 9.
One of these branch passages 14 has a solenoid valve 15 in the middle.
There is one intervention in each case. tl,i: The 9J valve 15 is configured so that the valve body 1511 is actuated by the electromagnetic actuator 15aIC to open and close the branch passage section 1f, and the 9J valve 15 opens and closes the branch passage section 1f at the timing shown in FIG.
(1 is set to close. In other words, in FIG. 3, a is the opening characteristic of the 111' air valve (not shown).

When the intake stroke begins, the intake air A is supplied to the cylinder 2 through the intake passage 37F. Then, when the second half of the culm 11 and 52'lh is J, the solenoid valve 15 is IJ.
<1 After the supercharging 4112, pressurized air B is supplied into the intake boat 9. At this time, the check valve 11 corresponding to the intake boat 91 is closed by its pressure f, and the pressurized air B is supplied to the cylinder 2 without flowing back to the vaporization D6 side. Ru. After 1u when the solenoid valve 15 closes and supercharging is stopped, the 1v intake valve 8 closes and the intake stroke ends. Therefore, such an operation is performed for each cylinder 2...l once per cycle of the engine.

ことが可能となる。First, during the middle of the intake stroke, where the cylinder volume changes significantly with respect to the crank angle, in other words, the cylinder negative pressure is large, intake is performed through the normal intake passage, and then,
Pressurized air or pressurized mixture is supplied from the supercharging passage into the cylinder 1.
Therefore, it is possible to obtain a supercharging effect of 11'' and 1' by using a supercharger with a small specific valley amount.
