Invention name: Sliding idle foam tube decompression piece.

technical field

The invention relates to a fuel atomizing device for a gasoline engine, in particular to a sliding type idle foam tube decompression piece.

Background technique

During the work of the carburetor, due to the wear and tear of the various measuring holes due to dust, especially the main foaming pipe, it must ensure the effective concentration of air and gasoline so that the engine can work normally. However, with the use of time and dust on the measuring holes The wear and tear of the air hole will cause the air hole to become larger, which will seriously affect the working condition of the engine.

Especially when the engine is refueled, it is easy to stall and have no idle speed, which seriously affects the normal operation of the engine.

This invention is to cooperate with the invention patent technology 'Carburetor fuel-saving maintenance method' applied for in 2008 and the 'Carburetor main nozzle support frame' applied for in 2012 to repair the main nozzle in the previous patented technology Finally, another energy-saving technology is added.

Contents of the invention

The purpose of the present invention is to provide a sliding idling foam tube decompression sheet, which makes the structure of the original carburetor simple and easy to maintain. service life, reduce exhaust emissions and other functions.

The present invention is realized by the following technical scheme: a sliding type idling foam tube decompression piece, which is composed of No. 1 decompression piece and No. 2 decompression piece. The No. 1 decompression piece is rolled into a semicircular grooved cylinder by steel plate, and the No. 2 decompression piece is sleeved on the outside of the No. 1 decompression piece. Insert the No. 1 decompression piece from the left side of the waist of the idling foam tube so that it can seal 2 air intake holes. According to the working conditions of the engine, move the No. 2 decompression piece so that it can seal 4 or 6 air intake holes. The air intake holes reduce or increase the amount of air entering the idle foam tube, effectively increasing the oil and gas concentration in the idle foam tube to meet the foam concentration of the engine in various working conditions.

At the same time, lower the main oil needle. Under the idle state, according to the actual gap between the main oil needle and the main nozzle after the main oil needle is lowered, then use the main nozzle shrinkage rod to reduce the inner diameter of the main nozzle to be consistent with the outer diameter of the main oil needle.

After warming up the car, adjust the fine-tuning screw to make the engine speed reach the highest point, and turn it slightly to a certain angle in the lean direction.

Check that the valve clearance and spark plug clearance must be within the standard range, the engine does not burn oil, and the electric enrichment valve is adjusted to a slightly open state.

After confirming the effect, after the car has been driven for 10 kilometers on normal road conditions, in order to discharge the carbon deposit or oil in the exhaust pipe, then, take a clean white paper, put the white paper on the tail of the exhaust pipe with one hand, and refuel with the other hand. There are dry black carbon marks on the white paper. Lower the main oil needle by one step, the carbon marks are slightly moist, and the engine lubricating oil is overfilled. The exhaust pipe with the echo chamber should have more moisture discharged, and the conventional exhaust pipe should have slight moisture on the paper.

Beneficial effects, using the present invention to improve the idling speed foaming tube of the carburetor can effectively solve the effects of gasoline and air being dilute due to foaming, causing power decline, unsmooth transition, and increased fuel consumption.

detailed description

A sliding type idling foam tube decompression sheet, composed of No. 1 decompression sheet 1 and No. 2 decompression sheet 2, characterized in that: said No. Rolled into a semicircular slotted cylinder, the No. 2 decompression piece 2 is sleeved on the outside of the No. 1 decompression piece 1 .

In FIG. 1 , No. 2 decompression sheet 2 shrinks to one side of No. 1 decompression sheet 1 .

In FIG. 2 , No. 2 decompression piece 2 protrudes to the other side of No. 1 decompression piece 1 .

The lower ends of the No. 1 decompression sheet 1 and the No. 2 decompression sheet 2 each have a groove.

The groove of the No. 2 decompression sheet 2 is smaller than the groove of the No. 1 decompression sheet 1, and the groove of the No. 2 decompression sheet 2 snaps into the groove of the No. 1 decompression sheet 1. The decompression piece 2 is tracked by the groove of the No. 1 decompression piece 1 to realize the movement of the No. 2 decompression piece 2 .

The No. 1 decompression piece 1 and the No. 2 decompression piece 2 are manganese steel, which are completed by stamping and heat treatment.

Case 1: A motorcycle with Wuyang Honda CG125 ejector rod engine, the idling speed is unstable, refueling is easy to turn off, the fine-tuning screw has little effect on adjustment, and the treatment method is to put the No. Snap in, the second decompression piece 2 is completely moved to the position of the first decompression piece 1, the first decompression piece 1 covers the air intake holes on each side, start the vehicle, screw the fine-tuning screw to the bottom and exit the engine for one turn The idling speed is very stable, and the engine does not tremble when the minimum speed is adjusted to 1000 rpm. The exhaust pipe of the refueling valve discharges more water vapor, and the power is increased by one gear than before.

Case 2: A Wuyang Honda curved beam C100 engine motorcycle needs to turn on the enrichment device every time it starts to start smoothly. The engine will turn off when the engine speed is lower than 2000 rpm. The adjustment of the fine-tuning screw has little effect. No. 1 decompression piece 1 snaps in from the left side of the waist of the idle foam tube, No. 2 decompression piece 2 moves halfway to increase the total area of No. 1 decompression piece 1 and No. 2 decompression piece 2, and No. 1 decompression piece 2 1. Cover one air intake hole on each side, No. 2 decompression plate 2 Cover the two air intake holes on the front, and lower the main oil needle to the most fuel-efficient position, start the vehicle, screw the fine-tuning screw to the end and exit halfway The idle speed of the engine is very stable, and the engine does not shake when the minimum speed is adjusted to 800 rpm. The exhaust pipe of the refueling valve emits more water vapor, and the acceleration from 0 to 60 kilometers is 1 second faster than before.

Case 3: A motorcycle with a CG150 engine, it is difficult to start when the car is cold, the engine cannot be controlled at medium and low speeds, and the fine-tuning screw has little effect on adjustment. The treatment method is to insert the No. 1 decompression piece 1 from the left side of the waist of the idle foam tube. , No. 2 decompression piece 2 moves to the end of No. 1 decompression piece 1 to maximize the total area. No. 1 decompression piece 1 covers each air intake hole on the side, and No. 2 decompression piece 2 covers the front The 2 air intake holes and the 2 air intake holes on both sides are covered, and the main oil needle is lowered to the most fuel-efficient position, start the vehicle, turn the fine-tuning screw to the end and exit one circle, the idle speed of the engine is very stable, and the minimum speed is adjusted to The engine does not shake at 1000 revolutions per minute, more water vapor is discharged from the exhaust pipe of the refueling valve, and the power returns to normal.
