Description

Auto fuel supply pressure and fuel atomization automatic control device

The present invention relates to an automatic fuel supply pressure and fuel atomization automatic control device for cars, and more particularly, in the supply of liquid fuel to the combustion chamber of the engine in accordance with the piston suction power of the combustion chamber, not directly forced supply by the fuel pump of the fuel tank Since the required amount of fuel is supplied and the fuel is automatically supplied in a nebulized state when the liquid fuel is supplied, the contact mixture between the combustion air and the atomized fuel is smoothed so that the combustion chamber is completely burned and the output of the vehicle is The present invention relates to an automatic fuel supply pressure and fuel atomization automatic control device that improves, generates noise, reduces exhaust gas from starting, and saves fuel due to proper fuel supply.

In general, the fuel supply of an automobile engine is to supply the liquid fuel of the fuel tank by a fuel pump or a high pressure pump.

However, the fuel pressures supplied by these pumps are supplied at a pressure so high that they cannot be used in the combustion chamber.

Therefore, the engine is equipped with a fuel pressure regulator in order to prevent such high pressure fuel from being supplied directly to the combustion chamber immediately.

At this time, the fuel pressure regulator serves to adjust the fuel pressure to be supplied to the combustion chamber and the fuel pressure to be returned to the fuel tank to receive the excess pressure of the fuel pumped by the pump.

In this way, the fuel pressure to be supplied to the combustion chamber is kept in the fuel supply pipe in which the injector, which is an injector for finally injecting fuel into the combustion chamber, is kept and the remaining fuel pressure is sent back to the fuel tank.

However, there is a disadvantage that the same pressure is always maintained in the fuel supply pipe by the fuel pressure regulator.

Due to these drawbacks, the inlet valve is opened to receive fuel from the combustion chamber during the intake stroke with the fuel pressure supplied to the combustion chamber already defined, and the fuel of the same pressure staying in the fuel supply pipe is opened at the moment the injector is opened. Regardless of the engine speed, a problem arises that it must be forcibly supplied.

In particular, the engine is simultaneously made by the timing belt to match the engine speed and the fuel injection time.

The fuel injection time supplied to the combustion chamber also coincides with the engine speed.

Therefore, when the engine speed is low, the injector is open for a long time, and the fuel injection time is long, so the amount of fuel supplied to the combustion chamber is increased, and when the engine speed is high, the time for injecting fuel is short, because the injector is short, the combustion chamber is short. The amount of fuel supplied to the car will also be reduced.

As a result, the fuel supply pressure is maintained the same by the fuel pressure regulator, but it may appear that there is no problem in the fuel supply because the flow rate supplied to the combustion chamber also changes according to the fuel injection time.

However, the fuel supply pressure should not be regarded as the correct fuel supply only by matching the fuel injection time according to the engine speed under the same fuel supply pressure. Since the load on the engine is different when the engine is lowered, the fuel pressure to be supplied to the combustion chamber must be selectively supplied according to the conditions of the different roads.

In addition, even when driving at the same speed, the load on the engine also works differently depending on how much a person rides or rides less, or when a lot of loads are loaded with less load. The need to supply selectively according to the conditions can be seen as the key to correct fuel supply.

However, the existing fuel supply technology does not have the technology to automatically adjust the fuel pressure according to various road conditions or driving conditions during driving. Therefore, the fuel pressure regulator is adjusted based on the fuel with the highest fuel consumption among the conditions so that the fuel supply pressure is not insufficient even when driving with a lot of luggage. At this time, there is a big problem that can lead to fuel waste.

In addition, excessively supplied fuel causes incomplete combustion in the combustion chamber, which generates exhaust gas that pollutes the atmosphere, threatening life, and even if the excessively supplied fuel is completely burned in the combustion chamber, more heat is applied to the engine than the atmosphere. It is being discharged to heavy water and it becomes the cause which adds to greenhouse gas.

Therefore, in order to improve this, Korean Patent Registration No. 10-378510 "Automatic fuel supply automatic control device" has been developed and presented by the present inventors.

It is composed so that the liquid fuel of the fuel tank is supplied from the fuel pump and passes through a multi-layered fuel pressure control cylinder in the fuel supply passage, and the fuel is supplied to the engine combustion chamber through the fuel suction pipe in the fuel supply chamber of the lower fuel container. The discs that make up the cylinder form a flat surface with a slippery surface.There is no center piece that supports the middle of the discs in the form of a ring between the discs to form the fuel flow path, so the middle of the discs is pressed between the upper and lower discs by the supply fuel pressure. As a result, there was a discontinuation of fuel flow.

In addition, the fast flow of liquid fuel did not produce enough particulate fuel to facilitate contact with combustion air.

In addition, the Korean Patent Application No. 10-2005-12218 was developed to improve the disadvantage of not making enough atomized fuel, which is a bumpy protrusion on the spacer plate for maintaining the gap between the plurality of fuel flow plates inside the fuel. By forming these lines and the uneven surface, forming the gear tooth surface on the middle partition plate, and forming the groove line on the fuel suction pipe, the liquid fuel flowed to improve the atomization state, but the atomization supply effect of the fuel Since there was an incompatibility, the Applicant has improved the conventional disadvantages and deficiencies listed above to further promote the fuel supply pressure and the atomization of the liquid fuel.

Its purpose is to make it possible.

In addition, since each air layer is formed in the upper portion of the fuel container to generate a pneumatic action, the required amount of fuel is supplied to the combustion chamber, thereby completely burning the vehicle, improving the output of the vehicle, reducing noise, and exhausting the engine from the start. Its purpose is to ensure that fuel is saved by supplying adequate fuel without gas generation and without wasting fuel.

In addition, the fuel suction pipe and the fuel discharge pipe are respectively connected and fixed in communication with each other, the inlet hole is formed in the cap in which the combustion chamber is formed, and the solenoid valve is provided in the inner side of the cap in which the inlet hole is formed. The valve operates to block the fuel intake pipe and simultaneously open the inlet hole formed in the cap so that the liquid fuel is supplied to the engine directly through the fuel discharge pipe without passing through the fuel supply container.

On the other hand, the fuel is not forcibly supplied by the fuel pressure regulator, but the purpose of the fuel is automatically supplied according to the suction pressure of the piston acting in the combustion chamber according to the engine speed.
