Abstract

PURPOSE: A high pressure cooling water is sprayed from a water pump to collect dust in an intake air, thereby preventing engine failure and blowby gas problem. CONSTITUTION: A sensing portion senses whether there are many dust. An electronic control unit operates a vacuum modulator by a signal from the sensing portion to open and close an operation valve connected to a thermostat housing. A spray pipe(30) is formed with a plurality of spray holes(30a) to spray a cooling water from a cooling pipe(3) in opening of the operation valve, thereby separating dust. The filtered air is introduced to an intake manifold(4).

Description

Intake system for alien substance elimination and elimination method

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an intake system for removing dust and debris from a vehicle engine. In particular, a coolant pipe, a drip case, a spray pipe, and an anti-bubble plate are formed between an air cleaner and an engine intake manifold. When the vehicle is operated in many areas, the high-pressure cooling water discharged from the water pump is sprayed in the form of a spray to filter dust and foreign substances into bubbles in the intake air containing fine dust and foreign substances. The present invention relates to an intake system for removing debris and a method for removing debris that flow into an intake manifold of an engine to enable combustion.

Although not shown, a conventional engine is configured to burn dust or foreign matter contained in the intake air by an air cleaner, so that the intake air from which dust or foreign matter is removed through the air cleaner is burned in the engine intake manifold.

However, in the related art, the air cleaner does not filter fine dust from dust or foreign matter contained in the intake air, and as a result, the fine dust is introduced into the combustion chamber together with the air, thereby adversely affecting a boring kit of the combustion chamber. There was a problem driving the engine is crazy.

That is, in the related art, fine dust that has passed through the air cleaner or dust coming into the sealing surface is introduced into the intake side of the engine as it is, followed by a closed stage that prematurely wears the boring kit of the engine. As a result, engine failure and excessive consumption of oil are caused. On the other hand, problems such as blow-by were caused.

Accordingly, the present invention has been made to solve the above-mentioned conventional problems, an object of the present invention is to form a cooling water pipe and the drip case and the spray pipe and the anti-bubble plate between the air cleaner and the engine intake manifold, When the vehicle runs in many areas, the high-pressure cooling water discharged from the water pump is sprayed in the form of a spray to collect fine dust and foreign matter contained in the intake air in the form of bubbles in the drip case, and pure air is the intake manifold of the engine. Intake for removing foreign substances that prevents engine failure, excessive consumption of oil, blow-by and other problems while preventing engine boring kits from premature wear due to fine dust. It is to provide a system and a method for removing foreign substances.

1 and 2, the sensor unit 10 for detecting whether the dust bundle area;

An electronic control unit (ECU) 20 that opens and closes the operation valve 2 connected to the thermostat housing by operating an engine negative pressure modulator 1 according to a signal detected from the sensor unit 10. and;

It is connected to the cooling pipe (3), when opening the operating valve (2) by spraying the high-pressure cooling water discharged through the cooling pipe (3) from the water pump in a spray method by primary filtered suction air from the air cleaner Spraying pipe 30 to form a plurality of spray holes (30a) in the front to separate the fine dust and the pure air flows into the intake manifold (4) to the combustion;

An anti-bubble plate 40 for forming fine dust separated from the intake air from the spraying operation of the spray pipe 30 into a bubble form;

A drip tray case for collecting fine dust made of bubbles from the bubble prevention plate 40; It consists of.

Hereinafter, reference numeral 5 denotes an alternator, and reference numeral 6 denotes an nipple for connecting an operation valve 2 connected to a cooling pipe 3 and a thermostat housing.

And, Figure 3 is a flow chart showing a foreign material removal method of the intake system is implemented from the intake system for removing foreign matter that is an embodiment of the present invention, the progress step,

Determining whether the driving place of the vehicle is a dusty area;

Spraying the high pressure cooling water discharged from the water pump by spraying the spray pipe 30 by opening the operation valve 2 connected to the thermostat housing when the dust bundle region is determined;

The high-pressure cooling water sprayed from the above step separates the fine dust from the first filtered suction air from the air cleaner to form a bubble and collect it into the drip case 50, and the pure air from which the fine dust is separated is intake manifold. Entering the fold (4) to combust;

Determining whether it is out of the dust bundle region from the step and repeating the above step if it is not out, and stopping the spray of the high pressure cooling water by closing the operation valve (2) if it is not out; Characterized in proceeding to.

Referring to Figures 1 and 2 attached to the operation of an embodiment of the present invention configured as described above are as follows.

First, the sensor unit 10 installed in the vehicle detects whether the driving place of the vehicle is a dust bundle area and then outputs the detection signal to the electronic control unit 20.

At this time, the electronic control unit 20 recognizes that the current driving place of the vehicle according to the signal detected from the sensor unit 10 is a dust bundle area, and then operates the engine pressure control device (1) to the thermostat housing The connected actuating valve 2 is opened.

Then, the spray pipe 30 connected to the cooling pipe 3 according to the opening of the operation valve 2 is discharged from the cooling pipe 3 through a plurality of spray holes 30a formed in the front thereof. Cooling water is sprayed by spraying.

At this time, the high pressure cooling water sprayed by the spray method from the spray pipe 30 separates the fine dust from the primary filtered intake air from the air cleaner,

The pure air from which the fine dust is separated is introduced into the intake manifold 4 so that combustion thereof can be performed.

On the other hand, the fine dust separated from the intake air from the spraying operation of the spray pipe 30 is made into a bubble form through the bubble prevention plate 40 and is then collected in the drip case 50, the drip case 50 Not only the bubble-shaped fine dust but also the high pressure cooling water sprayed through the spray pipe 30 performs a function of collecting together.

In addition, when the driving place of the vehicle is outside the dust bundle area, the electronic control unit 20 operates the engine negative pressure automatic control device 1 to close the operation valve (2) connected to the thermostat housing, Spraying of the coolant through the spray pipe 30 was stopped.

Therefore, the present invention which separates the fine dust from the primary filtered intake air from the air cleaner as described above, effectively removes the fine dust from the intake air flowing into the intake side of the engine, thereby reducing the performance of the engine This can prevent premature wear of the engine boring kit.

As described above, the present invention forms a coolant pipe, a drip case, a spray pipe, and an air bubble preventing plate between the air cleaner and the engine intake manifold, so that the high pressure discharged from the water pump when the vehicle runs in a dusty area By spraying the coolant in the form of a spray to collect dust and foreign substances contained in the intake air into the drip case in the form of bubbles, and pure air flows into the intake manifold of the engine to allow combustion. Boring kits prevent premature wear and prevent engine failure, excessive oil consumption and blow-by problems.

The present invention is not limited to the above-described specific preferred embodiments, and various modifications can be made by any person having ordinary skill in the art without departing from the gist of the present invention claimed in the claims. Of course, such changes will fall within the scope of the claims.
