[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an increase in output of a prime mover of an automobile using an internal combustion engine as a prime mover, and by utilizing anti-braking energy generated during braking, the prime mover is forcibly supplied with a filling effect. By increasing the output, it aims to increase output, save fuel consumption, reduce harmful exhaust gas, and improve driving safety by braking effect.

[0002]

2. Description of the Related Art As one of the methods for increasing the output of an internal combustion engine of an automobile, in order to improve intake efficiency, a turbocharger driven by exhaust pressure or a supercharger driven by crankshaft is used as a part of a prime mover. Is installed.

[0003]

The conventional supercharger for automobiles, which has been conventionally installed, has the effect of increasing the output, and at the same time, a loss of self-output for driving the supercharger occurs. Also, while a good filling effect can be obtained when the prime mover rotates at high speed, it is difficult to obtain good results at low speed and acceleration. Therefore, in order to almost eliminate the loss of self-output, such as in a supercharger, seek another power source, and configure an appropriate amount of air supply method and device according to the needs of the prime mover. Is the purpose.

[0004]

[Means for Solving the Problems] While driving an automobile at high speed,
Or, I am trying to stop while descending a slope, but it does not stop easily. This is due to anti-braking energy due to inertia (physically, gravity and inertia due to acceleration) during traveling, and is inevitably generated at each braking. The method and apparatus of the present invention measure the forced air supply to the prime mover by effectively utilizing this anti-braking energy. First, the energy generated in the wheels is taken out from the power transmission device of the automobile, the air compressor is driven as a power source, and the air compressed by the compressor is accumulated in the air tank. The accumulated air is guided to the prime mover, and the air supply regulator adjusts the pressure and flow rate according to the operating conditions of the prime mover to eject into the prime mover and improve the suction effect. By using this device, there is almost no loss of self-output such as when installing a supercharger, and by supplying the accumulated air by the air supply regulator, an appropriate amount of forced air supply to the prime mover is achieved. it can.

[0005]

The anti-braking energy generated when the vehicle is braked is used as a power source to operate the air compressor by operating the switch and the clutch that interlock with the brake pedal, and the air compressor operates to compress the air and store it in the air tank. .. The accumulated air is guided to the air supply regulator, the pressure and flow rate are adjusted by the action of the air supply regulator, and the air is ejected into the suction pipe of the prime mover to increase the intake air amount of the prime mover.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A power take-off device, a pulley (2) or a gear is fixed on a propeller shaft (1) for a power transmission of an automobile using an internal combustion engine as a prime mover, and a belt (3) shown in FIG.
Alternatively, an air compressor (8) having an electromagnetic clutch (6) and a pressure valve (7) is connected via a gear. Air piping (10) from the pressure valve of the air compressor to the air tank (9)
Connected to, from the air tank, the engine air intake pipe (20)
An air supply regulator (1) having an air outlet (16) installed inside
Also connect the air pipe (11) to 2). The operation of the air compressor is via the brake pedal (4). When the brake pedal is stepped on while the vehicle is running, the switch (5) provided near the brake pedal support shaft is turned "on", and the current from the power supply flows to the electromagnetic clutch of the air compressor to connect the clutch. When the clutch is connected, the compressor is driven by the rotating force of the propeller shaft via the pulley and the belt, and the air is compressed by the rotation of the compressor and accumulated in the air tank through the pressure valve and the pipe. When you release your foot from the brake pedal, the switch turns off, the electromagnetic clutch releases, and the compressor stops. The pressure valve of the air compressor is provided so as to apply a certain load or more to the compressor regardless of the air pressure in the air tank and obtain a braking effect similar to engine braking. The air supply regulator (12) is a pressure controller (1
3), electromagnetic coil, and air valve (1
4), and the air ejection port (16) is installed inside the air suction pipe of the prime mover. The air from the air tank passes through the pipe, enters the pressure controller, is depressurized to a pressure suitable for air supply, enters the electromagnetic air valve chamber (15), and is proportional to the current flowing through the electromagnetic coil of the air supply regulator. Movable and openable air valve,
It passes between the valve seats and ejects from the ejection port in the engine suction pipe. The electromagnetically movable air valve is an electromagnetic coil (17) that controls the current in conjunction with the accelerator mechanism, and an electromagnetic coil (18) that comprehensively controls the current based on signals from sensors such as motor temperature, rotation speed, output, and exhaust gas concentration. The combined use of) will allow forced air supply from the fully closed state to the fully open state with the air volume that is closest to the operating condition of the prime mover. FIG. 2 shows the air valve of the air supply regulator fully closed when the engine is switched off, when the prime mover is at a low temperature, and when the engine is idling. FIG. 3 shows the same air valve fully opened at the time of acceleration, high output, and the like. The air ejection port (16) in the prime mover air intake pipe is installed at an angle and position toward the air inflow destination direction (direction of the prime mover combustion chamber). When the air valve is opened as required by the prime mover, air is ejected from the ejection port. When high-pressure air is ejected from the ejection port into the air that is naturally inhaled by the prime mover itself, a pumping force is generated on the front surface of the ejection port and a suction force is generated on the rear surface. Therefore, the inflow velocity and flow rate of the air that is flowing in naturally are increased, and the air is pressure-fed into the combustion chamber. As described above, the method is characterized in that not only the air compressed and accumulated by the compressor is fed in and forced air is supplied, but also the air in the self-suction of the prime mover is increased to perform pressure feeding and filling. ..

The anti-braking energy extraction operation is performed by hydraulically operating the clutch of the air compressor by utilizing a part of the hydraulic pressure of the braking device generated by the brake pedal, not by the electric switch or the electromagnetic clutch. A clutch mechanism can also be adopted.

When the clutch of the air compressor has a pre-discontinuity that causes shock and noise at high speed running, the clutch structure is a multi-plate type or a fluid clutch, or a fluid joint is provided between the compressor main shaft and the clutch. It is easy to solve by using.

The air ejecting device of the air supply regulator described above is intended to increase the amount of natural intake air of the prime mover by applying the principle of the ejector for vacuum generation, by the ejected air. Therefore, unlike the supercharger, it is not necessary to supply the total intake air amount to the prime mover, so that the amount of air supplied from the air compressor can be reduced.

When air is ejected from the air ejection port into the suction pipe, discharge cooling due to adiabatic expansion occurs, so that there is no need for a cooler (intercooler) installed in the supercharger.

[0011]

According to the present invention, the anti-braking energy, which is inevitably generated when the vehicle is braked, is effectively used to drive the air compressor, compress and store the air, and guide the air to the prime mover. It is a method and device of forced air supply that ejects it into the suction pipe of a prime mover by a regulator.It measures the self-power loss of the prime mover to almost eliminate the self-power loss, and saves fuel consumption due to the combustion effect. Improved driving safety can be expected due to the reduction of exhaust gas and the braking effect of the air compressor load.
