Excuse me, Mr. Tan Xue: Which is better, the vacuum membrane carburetor or the plunger carburetor, and which is more fuel efficient?

The following information is for your reference.

Direct comparison between two carburetors in matching, price, use and performance ~ ~ ~;

1, support:

The plunger throttle carburetor is usually equipped with a chain-driven gearbox, and the isobaric vacuum diaphragm carburetor is usually equipped with a belt-driven scooter.

2. Price:

The plunger throttle carburetor is generally 40 ~ 80 RMB, and the isobaric vacuum diaphragm carburetor is generally 80 ~ 180 RMB.

Step 3 use:

Don't screw the throttle quickly, you need to add it slowly. The constant pressure vacuum diaphragm carburetor can fill the valve at will, which is suitable for beginners.

4. Performance:

Plunger throttle carburetors are usually more fuel efficient and easier to adjust. Constant pressure vacuum diaphragm carburetor usually consumes a lot of oil and is difficult to adjust.

5. Reliability:

The plunger throttle carburetor is simple in structure, stable in performance, reliable and durable. Isobaric vacuum diaphragm carburetor has complex structure and poor stability.

6. improvement:

The improvement of plunger throttle carburetor is mainly to change the oil concentration. The improvement of constant pressure vacuum diaphragm carburetor includes n aspects.

7. Improvement difficulty:

The plunger throttle carburetor is simple in structure and easy to replace. Isobaric vacuum diaphragm carburetor is complex in structure, difficult to refit and needs leveling.

8. Durability:

The plunger throttle carburetor has been used continuously for nine years. The satisfaction period of constant pressure vacuum diaphragm carburetor is usually only a few months.

9. Annex questions:

The plunger throttle carburetor has almost no parts quality problems, and the quality of the electrothermal enrichment acceleration pump of the isobaric vacuum diaphragm carburetor is very poor.

10, throttle line problem:

The throttle line of the plunger throttle carburetor should pass through the plunger hitch device, and the throttle line of the isobaric vacuum diaphragm carburetor can be hitched outside.

1 1, oil supply concentration problem:

The plunger carburetor will reduce the concentration of oil and gas when accelerating, and often reach a point of lean oil state to eliminate the carbon deposition in the spark plug and combustion chamber.

There is little chance that the vacuum membrane carburetor is poor in oil, and it is difficult to adjust it to a precise and accurate level, so the combustion chamber and spark plug often have carbon deposition problems.

12, carburetor maintenance and repair:

Plunger carburetor is easy to clean, maintain and refit itself, but it is more difficult to clean, maintain and repair isobaric vacuum diaphragm carburetor.
