Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an air supply system for an engine, and particularly to an air supply system for an engine that makes it possible to supply air with a high oxygen concentration.

[Conventional technology]

Since the output Vi of the engine is obtained by mixing the air and the fuel phase, in order to improve the output, the first step is to suck as much air as possible into the cylinder. For this reason, today, a turbine wheel is driven by engine exhaust gas, and a compressor blade integrated into the turbine wheel is rotated to compress intake air. Turbochargers have been provided that supply fuel into the combustion chamber of an engine and explosively burn a large amount of fuel in response to the supplied fuel to improve output torque.

[Problem that the invention seeks to solve]

However, in such a turbocharger, outside air is passed through a filter, compressed, and supplied into the combustion chamber of the engine, so a large driving force is required to compress the air, and sufficient intake air intake is required. Become. For this reason,
It is necessary to make the turbine, the combustion engine, and the intake pipe larger than a certain size. Furthermore, the combustion efficiency of fuel relative to the set intake air amount in the combustion chamber is relatively low. Because the amount of oxygen contained in the intake air volume is small,
Even though the amount of intake air is sufficient, the combustion efficiency of fuel with oxygen is not good.

The present invention was constructed by focusing on such conventional problems, and its purpose is to forcibly feed air with high oxygen concentration into the combustion chamber to provide intake air supercharging to the combustion chamber. An object of the present invention is to propose an air supply system for an engine that can sufficiently improve combustion efficiency and greatly improve engine output.

[Means for solving problems]

The engine air supply device of the present invention includes an engine air supply system that includes:
A means for decomposing oxygen molecules in the intake air is provided, and air with a high concentration of smoked oxygen molecules is supplied into the combustion chamber.

[Effect]

During operation of the engine, air is drawn into the engine's intake system by the reciprocating movement of the piston within the cylinder and the rotation of the intake air supercharging compressor (fan). This sucked air is separated by oxygen separation means into air that contains a large amount of oxygen molecules and air that contains few oxygen molecules and a large amount of nitrogen molecules, etc. Of these, only the air that contains a large amount of oxygen is used in the combustion chamber of the engine. supplied to

Therefore, the combustion chamber is sufficiently filled with oxygen that contributes to fuel combustion, which improves fuel ignition and combustion speed, improves engine startability and engine output, and further reduces fuel consumption. I can do it.

[Embodiments of the invention]

Hereinafter, specific examples of the present invention will be explained in detail with reference to the drawings.

FIG. 1 shows one specific example. Reference numeral 1 designates an intake pipe provided in the intake system, which has a single intake air amount l'', but is branched into two intake ports, an exhaust port 3 and an air supply port 4. The intake manifold 2 is provided with a filter 5 for removing dust, fine sand, and dirt from the air, and a fan for promoting air supply (if necessary, this is connected to the turbocharger) is installed in the intake pipe 1 on the downstream side of the filter 5. 6 (which can also be a compressor) is provided. This air supply promotion fan 6 is driven by a motor 7 installed outside the intake pipe 1, and when the fan 6 is used for intake supercharging, the motor is 7 is used to increase the rotation speed.

On the other hand, a triangular ceramic discharge plate 8 is provided near the branching part of the exhaust port 3 and the air supply port 4 in the intake pipe 1. , - an electrode 9 as an oxygen separation means at a foot distance apart;
, 1o are provided. The ceramic discharge plate 8 is composed of a pair of aluminum electrodes with an insulating material sandwiched therebetween, and a high-voltage AC power source 11 is connected to the pair of aluminum electrodes. On the other hand, a negative DC voltage is applied to the electrode 9, and a positive DC voltage is applied to the electrode 1° from a general DC power source (not shown).

In such an engine air supply system, an intake operation is performed by the operation of the engine and 60 rotations of the fan, and at this time, air outside the vehicle cabin is forcibly introduced into the intake pipe 1 through the filter 5 .

The air that has passed through the filter 5 is relatively clean, and when this air passes near the ceramic discharge plate 8, oxygen molecules in the air are separated by high-pressure discharge between the discharge electrodes. In other words, air is separated into oxygen molecules centered around ozone 08 and nitrogen molecules N2. Since ozone 03 is a negative ion and nitrogen N2 is a positive ion, ozone O and l are attracted to the electrode 10 and flow toward the air supply port 4.
Nitrogen N2 is attracted by the electrode 9 and flows toward the extraction port 3 side.

Is the air containing a large amount of oxygen 4V at the air supply port? c), is taken into the combustion chamber, and is first discharged outside the air system, which contains a large amount of nitrogen. As a result, the absolute value of the amount of oxygen in the combustion chamber relative to the amount of intake air is significantly increased, and the fuel combustion efficiency is significantly improved f/C.

In such an embodiment, due to the intake pressure generated when the engine is operating and the intake action of the fans 26 and 27,
Outside air passes through the discharge electrodes 21 and 22 and is sucked into the intake pipe 1A. At this time, a silent discharge occurs between the discharge awakening electrodes 21 and 22, and ozone 03, oxygen 02, and nitrogen N2 are separated from the air. These oxygen ions and nitrogen ions are attracted by the electrodes 25 and 24, respectively, and move. Therefore, air containing many oxygen molecules flows inside the air supply port 3A, increasing the oxygen concentration in the combustion chamber, thereby improving combustion efficiency and power performance as in the first embodiment. can be achieved. Note that the air containing N2 ions is discharged to the outside air from the exhaust port.
