What is the reason why the motorcycle carburetor sprays a lot of gasoline into the cylinder and does

Motorcycle carburetor.

If a lot of gasoline is sprayed into the cylinder and it does not catch fire, this situation may be caused by the carburetor oil level is out of control, and the cylinder is flooded due to excessive oil intake.

If there is too much oil in the cylinder of the motorcycle, you should check whether the oil level of the carburetor is too high, whether the float is damaged or stuck and cannot float with the oil surface, resulting in the loss of control of the oil level, whether the float needle valve is worn or stuck by the tiny impurities in the gasoline, resulting in poor closure, so that the oil level is out of control, whether the main measuring hole falls off, damaged or other reasons cause the nozzle hole to be too large, which will cause a lot of oil to enter the cylinder.

In addition, if the motorcycle is overturned, gasoline may flow directly into the cylinder from the fuel tank and carburetor through the intake pipe between the carburetor and the engine, causing excess gasoline in the cylinder. If too much gasoline enters the cylinder, it will wet the spark plugs.

And cause the mixture to be too thick and flooded the cylinder, so that the spark plug can not be ignited normally, resulting in the inability to start.

In addition, too much gasoline can leak into the engine crankcase and gearbox through the gap between the cylinder block and the piston and piston rings.

Internally, it is mixed with engine oil, resulting in more oil, thinner and worse lubrication effect, affecting the lubrication quality of the engine, and also causing oil leakage, increased engine wear and other failures. Therefore, in this case, after ruling out the fault of too much oil in the cylinder and unable to start, the oil condition in the engine should also be checked, and if the gasoline has penetrated into it and mixed with the oil, the oil must be replaced.

It's the float of the carburetor that's stuck.

Causing oil spills. That is, it is caused by not being cleaned.

Carburetor. The problem may be that the triangular needle of the carburetor is stuck by impurities in the gasoline and cleaned.

Will it jump over the fire to start, find a maintenance worker, this method can,

It is related to both the ignition system and the engine valve mechanism, so the specific fault needs to be specifically eliminated.

Under normal circumstances, replacing the carburetor is nothing more than oil leakage or poor atomization effect, and the matching degree when replacing the carburetor is definitely a problem that must be considered.

Although the shape of the carburetor is extremely similar, its internal main measuring hole, plunger size, and oil needle thickness are all different, so if the replacement carburetor does not match the engine model, it will not be able to fill the oil.

First, it is very important to choose the right model, since it is a motorcycle tour, it is generally more suitable to multi-functional recreational vehicles or ADV, these cars are generally targeted design, large fuel tank capacity, long endurance, high ground clearance, strong passing capacity, strong frame, comfortable sitting posture, for alleviating the fatigue of long-distance motorcycle travel is very meaningful.

Second, the brand is very important, the brand represents the quality, try to choose the brand with a large number of shares, these brands have been verified by the market, and most of them have been improved by manufacturers, and the quality is relatively more stable.

Third, protection is very important, long-distance motorcycle travel is generally far away from your familiar environment, in an unfamiliar environment, you must not be familiar with the road conditions, so try to wear as much protective equipment as possible, helmets, gloves, elbow pads, knee pads, professional riding boots, etc., motorcycles must be equipped with guards, can play a certain role in protection when falling.

There is no oil in the carburetor of the motorcycle, which is nothing more than that: 1, the fuel tank switch is broken, 2 the filter screen of the fuel tank switch is blocked, 3, the oil pipe is blocked, 4 the float needle is stuck, according to this procedure, check step by step, and find the problem. Just give the exclusion.

There are several reasons that can be excluded from the following aspects:

1.Carburetor measuring hole, needle valve hole blocked

2.The carburetor is not properly matched with the air filter or there is a connection installation problem, and there is an air leak, which makes the carburetor mixture too thin.

3.The fuel switch is not well oiled (if there is a negative pressure pipe leakage on the scooter, it will also cause a failure to get oiled) 4The oil level of the carburetor is too low (branded products are relatively rare).

5.The gasoline filter is clogged.

One is it! The switch is off! Or the oil road is blocked! There are only these 2 reasons.

The 125 scooter has gasoline in its carburetor, but it cannot supply fuel to the engine, which is usually caused by a clogged carburetor. You can remove the carburetor from the car and clean it carefully, clean the dirt in the carburetor with carburetor cleaner or gasoline, blow through the various nozzles and nozzles in the carburetor with the compressed air of the air pump or the daredevil, if the nozzle holes are seriously blocked, you can also use thin steel wire to dredge, but be careful not to scratch or scratch the nozzle holes, otherwise the carburetor will be damaged.

Check the carburetor mix ratio, oil level, oil needle, vacuum membrane and electronically controlled damper for problems, which can also affect the carburetor oil supply. Check whether the negative pressure fuel tank switch is damaged, as well as whether the suction pipe of the negative pressure fuel tank switch is leaking, whether the gasoline filter is blocked, whether there is no gasoline in the tank or there is too little gasoline, etc., these will also affect the fuel supply.

In addition, check whether the cylinder pressure is too low, whether the valve clearance is too small or the valve is not closed tightly due to carbon deposit, wear, ablation, etc., whether there is a slight leakage in the intake pipe and other hoses related to the engine, carburetor, secondary air intake system, negative pressure fuel tank switch, etc., and whether the gasoline oil quality is too poor, etc., which will also cause the failure of no oil supply or similar no oil supply.

Be. 1. The mixture is too thin: the mixture is too thin when the cold car starts, which is one of the reasons for the difficulty of starting, in this case, the concentration valve should be opened or the concentration of the carburetor mixture should be readjusted, and the starting automatic gas addition device should be checked for LK80T to see if it works normally.

There is a slight air leakage, which generally occurs at the carburetor and the intake pipe head or at the junction of the left and right crankcases. Apply some soapy water to the joint or joint seam and start it with a few clicks.

2. The spark plug was seriously drowned due to carbon deposits. The user should replace the spark plug.

3. Electronic ignition failure: In addition to checking whether the oil in the oil tank is mixed with water and whether the oil pipe is smooth, the oil supply system mainly checks the carburetor, and the carburetor is often due to too many impurities in the float chamber and blocking the main measuring hole, resulting in poor oil supply.

<> if there is oil leakage from the overflowing deflector pipe, it means that the oil level is high. After the oil level is high, it is possible to leak oil into the engine, and then it will not be able to start until it starts, and a lot of oil will accumulate in the cylinder, which will cause spark plugs.

Drown. Remove the spark plug, plug the spark plug hole with your hand, and activate it to let the air leak spray. Then change to a new spark plug to start the fire, if the fire is very strong, it can almost start, then the problem is solved, if it can't be started, you have to clean the carburetor again, remove the exhaust pipe to start!

You can consider cleaning the carburetor, pulling out the oil pipe to confirm that the oil is coming out of the oil pipe (the scooter should start the engine electrically), block the carburetor intake with your fingers (don't block it too tightly) and step on the starting lever (electric start engine), and the engine may start when you feel that there is oil on your hands

Reason: The carburetor is not sprayed, but sucked in by the negative pressure of the piston movement, just like a syringe absorbs water or inhales. If the tank runs out of oil, or the pipes in the carburetor are clogged, the mixer will not work.

The simple carburetor consists of three parts: the upper part has the air intake port and float chamber, the middle part has the throat, measuring hole and nozzle, and the lower part has the throttle valve.

The float chamber is a rectangular container that stores gasoline from a gasoline pump, and a float inside the container controls the amount of fuel intake by using the height of the float (oil level). One end of the nozzle is connected to the measuring hole of the float chamber, and the other end of the nozzle is at the throat of the throat.

1. The oil level is too low: the oil level of the carburetor is too low, which is mostly due to improper adjustment. In order to pursue the low fuel consumption of the vehicle, some riders and maintenance personnel blindly adjust the float to reduce the oil level in the float chamber, and use the engine to absorb less fuel at the same speed to reduce fuel consumption, in fact, this method does not outweigh the losses.

2. The oil level is too high: the needle valve and the needle valve seat oil sealing working surface are worn, and the wear of the needle valve is the most serious. When the needle valve is worn, a cut mark (introduced) is formed on the working face of the needle valve, because the needle valve and the needle seat can not be automatically centered, the fuel will continue to flow into the float chamber, resulting in the oil level being too high.

3. The replacement accessories are not suitable: the matching gap between the needle valve and the guide sleeve is, if the gap is too small, it will affect the start and close of the oil inlet, resulting in the loss of control of the carburetor oil level, but this kind of fault phenomenon is less.

The carburetor of the motorcycle is formed by the negative pressure of the piston, and the vacuum is sucked into the cylinder to form a good mixture, and then the spark plug point makes the car work. If it can't start normally, check 1, whether the oil is sufficient, whether the oil is qualified, and whether the air filter is blocked. 2. Whether the ignition of the spark plug is normal and what is the clearance.

3. If there is no problem with these two, look at whether the vacuum pipe on the carburetor is connected, whether it falls off, and whether the bolt is loose. If there is no problem to remove the carburetor, first see whether the oil surface at the bottom of the carburetor is sufficient, if it is insufficient, adjust the oil float height, and then decompose the oil to clean all the measuring holes with "carburetor cleaning agent" to keep all the measuring holes unobstructed.

No pressure!Just change it.

Why does gasoline not enter the engine after the carburetor is cleaned, and what is the reason?

My car has been on for a year, and it can't be bad.
