Accordingly, water, heated in a fore exhaust pipe 4, flows into the evaporator 6, becomes the wet steam and is mixed with the warm air of the warm air supplying pipe 9, thereafter, is mixed with the fuel in a carburettor 20 and is sent into the engine E.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for increasing fuel efficiency and L1 output of an internal combustion engine such as a gasoline engine or a diesel engine.

Conventionally, various means have been provided for efficiently burning fuel in an internal combustion engine to improve fuel efficiency and increase output. However, the equipment for this is complicated and expensive,
The drawback was that the effectiveness did not increase depending on the rotational speed of the internal combustion engine.

As a means of achieving the above-mentioned goal, it is sufficient to always select the optimal mixture ratio of air and fuel, but in reality, the internal combustion engine
Since it is controlled by external conditions, it requires a high level of skill.

In addition, there is a method of increasing the output by dripping or spraying water into the combustion chamber along with the fuel and utilizing the large expansion force when the water evaporates, but this can cause rust inside the cylinder. There are disadvantages such as poor combustion because the fuel and water are not sufficiently compatible, and the combustion temperature remains constant due to the water.

This invention focuses on the fact that water in the liquid phase has a large expansion force when evaporated, and that water causes a high twisting reaction with fuel. The mixture of air, moist steam, and fuel is created by mixing an appropriate amount of moist water vapor at an appropriate temperature into the air that is drawn into the combustion chamber together with fuel. Combustion, fuel efficiency, output direction 1-
The aim is to aim at seven.

Below is an example of the application to an automobile gasoline engine. it
; Next, this invention will be explained.

This invention mainly consists of a water supply means, an evaporator, an air supply means, and a mixed air supply pipe.

First, regarding the water supply means, (T) is a tank containing water, and (1) is a water supply pipe that supplies water from the tank (T) to an evaporator (6), which will be described later. (P) is a water supply pump, and between the pump (P) and the evaporator (6), there is a solenoid valve (2) that cuts off the water supply to the evaporator, and a water supply amount? There are seven flow rate adjustment valves (3) to adjust, and the water supply pipe (1) coming out of the flow rate adjustment valve (3) is connected to the front exhaust pipe (4), the exhaust manifold (
5) It passes through and opens at the bottom of the evaporator (6).

The evaporator H (6) contains stainless steel wool (7) and is fixed on the exhaust manifold (5).

Regarding the air supply means, (8) is an outside air supply pipe connected to the evaporator (6), and this outside air supply pipe (8) K
A warm air supply pipe (9) having a warm air intake OQ that opens near the front exhaust pipe (4) is connected to the front exhaust pipe (4). (
The trick is to switch between the two supply pipes with a switching valve installed at the connection between the two supply pipes (8) and (9).

The mixed air supply pipe a2 connects the evaporator (6) and air cleaner 0]
It connects the

Note that the solenoid valve (2) is operated by the temperature regulator u, in response to a signal from a humidity sensor aIO that detects the internal temperature of the evaporator (6).

Similarly, the operation of the switching valve 0) is controlled by the signal from the temperature sensor 0Q that detects the temperature inside the mixed air supply pipe 0.
(171)

Further, the flow rate adjustment valve (3) is operated in conjunction with the operation of the accelerator Oa.

As another embodiment, the solenoid valve (2) is eliminated and the evaporator (
6) The flow rate adjustment valve (3) can also be operated by the humidity sensor 04 and temperature controller QeK.

Next, the operation and effects of this invention will be explained.

When starting the engine (E), that is, while the engine temperature is low, the solenoid valve (2) is closed, the switching valve αυ is closed, that is, the outside air supply pipe (
8) Closed. When the engine temperature rises and the temperature inside the evaporator (6) rises, the solenoid valve opens and the switching valve closes. Furthermore, when the temperature inside the mixed air supply pipe (6) rises, the solenoid valve (2) closes. ) remains open, the switching valve αυ is open, that is, the temperature controller #i is set in advance so that the outside air supply pipe (8) is open and the warm air supply pipe (9) is closed.
Adjust η.

In the example, the opening of the solenoid valve (2) is approximately 50°C1 switching valve Q
The switching of l) is approximately 80'C.

Now, when the engine (E) is started, the solenoid valve (2) is closed, so the water supplied from the pump (P) passes through the return pipe O having a check valve (not shown) to the tank ( Return to T). Therefore, water is not supplied to the evaporator (6), and the warm air supply pipe (10) is gradually lowered in temperature from the warm air intake (10).
The air passing through 9) is sent to the evaporator (6), and the mixed air supply M
! (Air cleaner 0.1& is entered through 12.) The mixture sent from the carburetor (A) to the engine is only air and fuel. This is to prevent the temperature of the mixture from lowering due to low-temperature wet steam.

The temperature of the engine (K) increases and the exhaust manifold (5
), and when the temperature inside the evaporator (6) reaches the set value due to the air warmed and sent in by the front exhaust pipe (4), the temperature controller a0 is activated by detection by the temperature sensor Q41.
opens the solenoid valve (2), and water supply to the evaporator (6) is started. The water warmed by the front exhaust pipe (4) enters the evaporator (6) and turns into wet steam to the warm air supply pipe (9).
The mixed air enters the carburetor (A) via the air cleaner (13), mixes with fuel, and is sent to the engine.

The mixture of air, water vapor, and fuel inside the cylinder contains water in a liquid phase with a high coefficient of body expansion, so it has a strong explosive force and improves engine output. In addition, 0 in water H20 and C in fuel OR cause an endothermic reaction and become C0-1-H, resulting in complete combustion, reducing unburned gas, saving fuel and preventing air pollution caused by exhaust gas. useful for.

When you step on the accelerator α barrel and increase the engine rotation, the flow rate adjustment valve (3) linked to the accelerator is activated, increasing the amount of water supplied to the evaporator (6) and increasing the amount of water in the mixture sent to the engine. The amount of wet water vapor increases.

Furthermore, when the temperature of the mixed air entering the air cleaner (to) exceeds the set value, the temperature controller F61 θ switches the switching valve αυ based on the detection Qζ of the temperature sensor OQ, and the outside air supply pipe (8
) only sends cold air to the evaporator (6), so the temperature inside the evaporator is lowered and the amount of humid steam generated is suppressed, ensuring that no more than an appropriate amount of humid steam is supplied to the engine. prevent.

Above, we have described examples of automobile engines.
In implementation in a diesel engine, in the air intake step 6, the air is mixed with humid water vapor generated in an evaporator.

Finally, the features of this invention will be listed.

(1) Since the coefficient of expansion of water is large, the explosive power is greater than that of a mixture of only air and fuel, which can improve horsepower and fuel efficiency.

(2) Due to the combustion heat generated at the moment of explosion in the combustion chamber, the fuel and water undergo an endothermic reaction, resulting in complete combustion of the fuel. Therefore, unburned gas is reduced, saving fuel and preventing air pollution.

(3) Furthermore, since the adhesion of unburned carbon υζ in the combustion chamber is reduced, the spark plug becomes clean and the air-fuel mixture is completely ignited.

(4) The amount of air decreases by the amount of water vapor in the mixed air, so
Nitrogen oxides in exhaust gas are reduced to prevent atmospheric contamination 1. I
Useful for Z.

(5) It can be easily and inexpensively implemented in existing internal combustion engines, regardless of the size of the IF.
