How to save fuel in the motorcycle carburetor, how to adjust the scooter carburetor to save fuel

I just want to tell you that the idle speed is 1300-1500, the unadjustable is too low, and there are 800-1000, not to be gullible. My first car is the idle speed adjustment is too low and early overhaul, mainly the car idle speed is low, the oil can not reach the head, resulting in insufficient lubrication, acceleration valve, rocker arm, piston wear, please do not lose a small loss, and then say that the idle speed is high waste of this bit of oil, basically negligible, you step on the brakes urgently, the emergency fuel pedal to cost oil that is called more, the car is not good, usually develop a slow accelerator, often use the engine to brake, do not stop and go quickly, slam the accelerator, that is called the master of fuel economy, The carburetor is a high-precision Dongdong, generally the factory is carefully adjusted, do not mess with the adjustment, you look at those after-sales apprentices, a carburetor has a problem, happy to be very happy, so you can take your carburetor to practice, broken, it is said to be a big problem, to change. If you don't adjust it well, it will cost you more fuel, then the gains outweigh the losses, there are too many so-called "experts" on the Internet, don't blindly obey, in short, it's actually good, after all, it's your own car, and it's heartache!

The above content is purely a personal opinion, it is up to you whether you listen to it or not, in short, it will not harm you, this can be assured!

Adjust the idle speed a little lower, just steady, and not extinguish. Try to ride in the highest gear and try not to turn off the engine.

The hole was plugged with copper wire, and the fuel-saving power was almost there.

Scooters.

The carburetor can only be adjusted to the right extent, so that the normal performance can be guaranteed, and it is impossible to make it more fuel-efficient and energetic than normal through adjustment.

There are many kinds of scooters, and their carburetors are basically vacuum membrane carburetors, and the general carburetor can adjust the idle speed.

Screws, mix-ratio screws and oil needles. The mixing ratio of this Sunbi roughening carburetor is clockwise.

Twist and dilute, twist and adjust the concentration counterclockwise, most of which are to screw the mixed screw clockwise to the end, and then withdraw counterclockwise about two and a half turns.

After adjusting the mixing ratio, start the engine to preheat, and adjust the idle speed after the car is warmed up, and the idle speed can be maintained at about 1600 rpm. If there is no tachometer, it is necessary to adjust it in combination with the maintenance experience. The oil needle of the carburetor has generally been adjusted at the factory, and there is no need or should be adjusted casually without special circumstances.

The carburetor is a relatively delicate component, if it really needs to be adjusted, it should be carried out by a repair personnel with professional maintenance experience, combined with the actual vehicle condition. And the adjustment of the Huahui lead oiler should be carried out on the premise of ensuring that there are no problems in other parts, otherwise it will be inaccurate.

There are usually two ways to save fuel in a carburetor:

Wire teeth on the side of the main nozzle;

Normally, slowly adjust the damper screws to the highest point at idling, and then adjust the idling speed to a normal level.

The carburetor has a total of 2 adjusting screws, one is at the plunger position of the carburetor, which is used to adjust the idle speed, screwing to the right is to increase the idle speed, and screwing to the left is to decrease; The other is a copper screw embedded in the carburetor, (you can find it if you look closely, because there are many types of carburetors, so the position is also slightly different) is used to carefully adjust the concentration of the mixture.

Under normal circumstances, the concentration of the mixture is controlled by him, the mixture is thickened to the right, and the mixture is thinned to the left, and the adjustment method is: screw the screw to the right to the end, and then twist it to the left for one and a half turns. This is a general adjustment, but it needs to be fine-tuned depending on the condition of each vehicle.

Adjust the main oil needle of the motorcycle's carburetor. In fact, unless it is really necessary, it is recommended not to adjust, because the reduction of oil intake after adjustment will affect the normal operation of the engine, resulting in power decline, engine overheating and other adverse effects. Again, the carburetor assembly is a very delicate component, there are certain requirements for assembly, unless you have assembled, otherwise you had better go to the repair shop to check and repair, has kept your car in the best condition.

This kind of inspection and adjustment is very cheap, only 20 to 30 yuan.

A carburetor is a mechanical device that mixes a certain proportion of gasoline with air under the action of vacuum generated by the operation of the engine. The carburetor is a delicate mechanical device that uses the kinetic energy of the inhaled air stream to atomize gasoline. Its important role in the engine can be called engine's"Heart"。

Its complete device should include a starting device, an idle device, a medium-load device, a full-load device, and an acceleration device. The carburetor will automatically mix out the corresponding concentration according to the different working state requirements of the engine, and output the corresponding amount of mixture, in order to make the mixture mix more uniformly, the carburetor also has the effect of atomizing the fuel for the normal operation of the machine.

A device that forms a combustible mixture between fuel oil such as gasoline and kerosene and air in a spark-ignition internal combustion engine (such as a gasoline engine), also known as a vaporizer. The function of the carburetor is: to provide the corresponding amount of fuel according to the requirements of different working conditions of the internal combustion engine; The fuel is atomized and evenly mixed with air to obtain a combustible mixture of a certain composition for good combustion; Ensure a smooth transition between the various operating conditions of the internal combustion engine.

In a spark-ignition internal combustion engine (such as a gasoline engine), a device that makes gasoline, kerosene and other fuel oil and air form a combustible mixture, Zhiyuan, also known as a vaporizer. The function of the carburetor is: to provide the corresponding amount of fuel according to the requirements of different working conditions of the internal combustion engine; The fuel is atomized and evenly mixed with air to obtain a combustible mixture of a certain composition for good combustion; Ensure a smooth transition between the various operating conditions of the internal combustion engine.

The pedal motorcycle suspects that the dust tray car is used to wait for the vacuum carburetor, and its socks can be adjusted by themselves only the mixing ratio screw, and the adjustment state is between the retract circles after screwing to the end, and there are almost no more than 2 circles of Qin Chan, more than 2 and a half turns of the carburetor may have some problems, and other positions should not be adjusted by themselves, otherwise it is easy to have some problems, and other vacuum carburetors are high-precision accessories, and non-professionals can not adjust or disassemble by themselves

It depends on whether there is anything wrong with the original carburetor. My scooter, the original fuel consumption liter liter 100 km, then rose and is not good for ignition, after changing the carburetor, the fuel consumption dropped to below.

It depends on whether it is the carburetor or not, if so, it will definitely save fuel if you change it.

To adjust the carburetor of the motorcycle, you need to clean the carburetor first, wipe the dust, etc., and then adjust it, the specific operation steps are as follows:

1. Install the plunger of the carburetor.

2. Install the plunger with an evolution oiler.

3. Install the carburetor on the engine.

4. Connect the oil pipe and open the oil valve.

5. Start the vehicle and use a special adjustment tool to rotate the mixer screw to the highest point of the engine speed.

6. Use a Phillips screwdriver, adjust the idle screw, adjust the idle speed to 1000 rpm, and complete the carburetor adjustment of the motorcycle.

If he didn't disassemble the carburetor is to adjust the adjusting screws of the mixer, use a small screwdriver, screw the screws of the mixer into the end, and then go ** to 3 turns, and there is another way, after the mixer is adjusted to the end, don't let the car turn off, turn the idle speed high, and then twist the mixer screws outward, adjust it to the highest idle speed, and then adjust the idle speed back, basically it's almost the same, it feels bad, and the mixer is fine-tuned.

It depends on whether you're a plug carburetor or an EFI! If it's an oil needle! Then you adjust the oil needle to the top one gram! That's the most fuel-efficient! But it may not be easy to ignite! Forget to adopt.

Not every carburetor can be tuned, not everyone can tune it!

1 Properly lower the oil level of the carburetor, this is a technical job, it is recommended not to move, let an experienced technician adjust it!

2.The gas mixture screw (under the connection between the carburetor and the engine) is removed for one and a half turns (normally it is one and a half times to remove, if you want to save fuel, you need to remove it a few more times, but the idle speed will be increased, so you need to adjust the idle screw).

The oil needle of the throttle valve of 3 carburetors (normally in the middle gear, adjust up to save fuel, down to reduce fuel consumption!!) ）

Scooters.

The carburetor can only be adjusted to the right extent, so that it can be guaranteed to perform normally, including normal fuel consumption and power levels. But if you want to make it more fuel-efficient and more energetic than normal through adjustment, it is also impossible, and there is some contradiction between fuel-saving and energetic, if you want to be energetic, you have to consume more gasoline, otherwise the strength comes from the **? In order to save fuel, it is inevitable to have an adverse impact on the power performance.

But even so, no matter how you adjust the carburetor, it can't be more fuel-efficient or more powerful than normal.

The fuel consumption of scooters is relatively large, their fuel consumption is greater than the same displacement of straddle motorcycles and curved beam motorcycles, which is mainly the problem of its transmission mode, because its continuously variable transmission system is relatively simple and imperfect, so it will have an adverse impact on fuel consumption and power. Carburetor is one of the important parts of the motorcycle, it has a very important role in the fuel consumption and power of the motorcycle, if the quality of the carburetor itself is poor, or the carburetor hand base has improper debugging, it will also increase fuel consumption and damage power, so to ensure that the quality of the use is qualified, the appropriate model of the carburetor under the premise, but also to ensure the correct installation and commissioning.

There are not many parts of the scooter carburetor that can be adjusted, the main thing is idling.

Mixing ratio, throttle valve column Qing chaotic plug oil needle, float chamber oil level, etc., some can also adjust the accelerator pump, these aspects have a greater impact on fuel consumption and power is mainly the mixing ratio screw. Like the above aspects, they can only be correctly adjusted to the appropriate standard, and cannot be considered to exceed the range, otherwise it will not only fail to achieve the purpose of fuel saving and strength, but also lead to adverse reactions in other aspects.

Such as high fuel consumption, difficult starting, weak acceleration, unstable operation, etc. The mixing ratio of the scooter to the screws is clockwise.

If you screw in the thinning and counterclockwise out of the thickening, you can generally screw the mixing ratio to the end clockwise, and then withdraw counterclockwise for about two and a half turns. However, it should be noted that not all carburetors are the same, even if they are of the same brand and model, there will be individual differences. The carburetor has been adjusted at the factory, and there is no special situation that does not need to be adjusted, if it really needs to be adjusted, it should also be carried out by repair personnel with professional maintenance experience, combined with the actual vehicle condition.

Open the carburetor float chamber and check whether the inlet needle valve is driven to fall when the float falls. If the needle valve does not move with the float and is still tightly combined with the Shenxing needle seat, it can be judged that the oil inlet channel is blocked due to the bonding between the needle valve and the valve seat, which is generally caused by the condensation of gasoline gum between the needle valve and the valve seat. Can be cleaned with alcohol or acetone.

This type of malfunction often occurs on motorcycles that are not in use for long periods of time. In particular, if the engine factory and motorcycle factory do not quickly let the gasoline in the carburetor float chamber be exhausted after installation, the gasoline colloidal condensation will occur when the inventory or sales period is slightly longer, resulting in carburetor performance failure

Remove the float and needle valve, access the gasoline from the carburetor inlet port, observe the gasoline outflow from the valve seat, if there is no gasoline outflow, the mu bureau is blocked by the oil inlet channel, and compressed air can be used to blow in from the oil inlet inlet portion.

In addition, a blockage in the oil circuit indicates that a large amount of impurities have entered the carburetor. The root cause is a failure of the gasoline filter. Therefore, the gasoline filter needs to be checked at the same time as the carburetor is cleaned.
