What causes a gasoline generator to pop when it starts?

The reason why the car engine is loud:

1. The existence of most common abnormal noises of the engine depends on the speed state of the engine. Abnormal noise only exists when running at idle or low speed; The sound is disordered when it is maintained at a certain speed, and it makes a brief sound when it decelerates sharply; Abnormal noises occur when the engine accelerates sharply, and the sound persists when running at high speeds.

2. The abnormal noise failure of the engine is often obviously related to the working cycle of the engine, especially the abnormal noise of the crank connecting rod mechanism and the valve mechanism are related to the working cycle. Usually, the sound caused by clearances unrelated to the duty cycle is mostly due to faulty engine accessories; If there is a continuous metal friction sound emitted by a mechanical part that is not related to the duty cycle, it can be considered that some rotating part is faulty.

3. The problem of the filter collector, the rubber ring is not well sealed, so that the oil pump cannot suck up the oil normally and suck a lot of air when it is working, and the engine system is not lubricated enough, especially the hydraulic tappet part of the valve, which makes a metal knocking sound; The filter collector is clogged and does not properly draw oil into the engine lubrication system, resulting in poor lubrication.

4. The oil pump is not working properly and cannot suck the oil in. Poorly lubricates the engine lubrication system.

5. The valve hydraulic tappet is partially damaged, and the related system does not work properly for a long time, resulting in insufficient lubrication of the parts and causing damage.

After all, the engine is the power source of the car, which plays an absolute role in the car as a whole, and the abnormal engine noise is also much concerned by the owner, because the abnormal noise of the engine generally needs to break the bank. Engine squeak can be divided into cold car squeak and hot car squeak.

There is also an abnormal noise when the engine is hot.

This may be commonly known as a cannon, that is, the unburned mixture burns in the exhaust pipe, resulting in a popping sound. This situation is caused by poor ignition of the spark plug or too late ignition, too thick mixture, ablation of the exhaust valve or too much carbon deposit, stuck in the exhaust valve, and the exhaust valve is not closed tightly.

Summary. Hello, I am your exclusive technician, attentive, careful, dedicated to answering your car questions, for you to find the corresponding problem solutions and solutions! According to the reason for the pop sound when your car is ignited, the answer to the question is as follows: First, the engine intake system is caused by air leakage, and you need to check the water inlet pipe!

Second, if there is an air leak in the engine exhaust system, you need to check the exhaust pipe, and whether the exhaust manifold is leaking! Third, check if there is any noise caused by abnormal interference in the contact between the engine accessories and the gearbox, such as the engine underguard! The above analysis of the gradual overhaul, the car master will serve you wholeheartedly, I hope my answer can help you!

Hello, this question can give you a perfect reply, wait for me to sort out the information, I'm typing, 2-3 minutes, don't finish.

When the fire is lit and the hail is brightened, there is a popping sound in the sails, and the vehicle will also have a state collapse when the start is shaking and can't refuel, what is the reason for this, the vehicle is Beijing Hyundai Tucson 15 years 16t.

If there is an air leak, check the air intake pipe for air leakage.

In general, the cause of "buzzing" is mostly on the mechanical hinge. This phenomenon occurs when the bearing does not perform well, or when the tension is not suitable.

The motor is represented by the letter M in the circuit (the old standard is D), its main role is to generate driving torque, as the power source of electrical appliances or various machinery, the generator is represented by the letter G in the circuit, and its main role is to use mechanical energy to convert into electrical energy.

Maintenance method of the motor:

1. The use environment should always be kept dry, the surface of the motor should be kept clean, and the air inlet should not be hindered by dust and fibers.

2. When the thermal protection of the motor is continuously activated, it should be found out whether the fault comes from the motor or the overload or the setting value of the protection device is too low, and the fault can be put into operation only after the fault is eliminated.

3. Good lubrication of the motor during operation should be ensured. The general motor runs for about 5000 hours, that is, the grease should be supplemented or replaced, and when the bearing is found to be overheated or the lubrication deteriorates, the hydraulic pressure should change the grease in time.

4. When the life of the bearing ends, the vibration and noise of the motor operation will increase significantly, and the radial clearance of the bearing should be replaced when the radial clearance of the bearing reaches the following values.

Summary. Hello, master, the reason why the vehicle can't start, first of all, you need to check whether the battery voltage of the vehicle is sufficient. The battery voltage needs to be above 12V.

If the voltage is insufficient, you need to find a battery to connect it. If the battery voltage is sufficient, you need to check whether the signal line of the starter is normal. Is there any response when you start?

If the engine can run, it just can't start and needs to be checked. Ignition coil and spark plug to check whether the fuel pressure is normal.

What is the reason for the popping sound when the gasoline engine starts, and the gasoline household generator slams when it pulls, but it can't catch fire.

Hello, master, the reason why the vehicle can't start late, first of all, you need to check whether the battery voltage of the vehicle is sufficient. The battery voltage needs to be above 12V. If the voltage is insufficient, you need to find a battery to connect it.

If the battery voltage is sufficient, you need to check whether the signal line of the starter is normal. Was there any anti-Huai deficiency when the lead Dan debate was launched? If the engine can run, it just can't start and needs to be checked.

Ignition coil and spark plug to check whether the fuel pressure is normal.

It's a household gasoline generator, the battery can't ignite, and then pull it by hand, and it will bang if you pull it a few times, but it won't catch fire, is it a problem?

Uh-huh. Focus on checking whether the oil circuit and carburetor are blocked.

At first, it was able to generate electricity, but suddenly it went out, and then it was such a failure.

In this case, it is recommended to clean the oil circuit and generator first.

What are the oil circuit cleaning circuits?

The main thing is the carburetor part.

Hello master, it's like this, isn't the fuel tank connected to this carburetor a transparent gasoline pipe, but there is no bubble in the middle of this part of the gasoline pipe.

In this case, it is normal if there are no bubbles, but if there are bubbles, it is caused by air. The main thing is to see that the carburetor or the device needs to be cleaned, and there may be slag blocking the fuel injection hole. At the moment, he just doesn't idle and will turn off automatically.

Summary. It should be that the valve clearance is wrong, tempering, and the clearance needs to be corrected.

It should be that the valve clearance is wrong, tempering, and the clearance needs to be corrected.

The sound is very loud, like a cannon, is it not gasoline bad and there is water.

1. At low speed, the speed is high and low, with an intermittent "abrupt" sound, and even unable to operate, which is caused by weak sparks or intermittent ignition, blocked oil circuits, and large throttle shaking. 2. There is a "coughing" sound at high speed, and the voltmeter pointer swings back and forth. This is caused by the weak person with the spark of the sun to hide the qing, continue to jump the fire, the spark plug gap is too large, too small, or leakage.

3. The speed and voltage of the machine change back and forth rhythmically or rhythmically, the exhaust does not smoke, does not discharge, and the exhaust sound changes according to the speed change of the device. This is caused by the improper position of the speed regulating spring frame or the excessive shaking of the speed control lever and throttle shaft, and the speed control lever and throttle valve can be seen shaking up and down.

After starting for a period of time, I forgot to open the damper, does it matter? Thank you<> when you start, you have to open the damper (move it up) and the air intake inside the carburetor lift die is closed! Because at this time, the noisy and slow aqi is very strong, and it is easy to start.

After starting, the damper is closed (removed) after a short period of warm-up. At this time, the inside is open. Because the engine needs fresh air to work properly.

You have to move the damper (down) when driving! The engine doesn't start, it doesn't work, the damper is open and closed!

Yes! Understood, is it that gasoline is not good and water, I used last year's oil in plastic barrels, does it matter! Thank you! <>

<> yes, yes, you need to change the container.

What is going on with the gasoline generator not ringing Hello dear, it may be due to the following reasons: 1. The belt is loose. 2. The battery is short of power.

3. Generator failure. 4. Charging line failure. 5. Controller failure.

6. The carbon brush of the starter is broken. 7. The motor starting gear is seriously worn and needs to be replaced. 8. There is a problem with the starting motor.

There is a problem with the starting motor, and the more common phenomenon is that the starting connection metal block in the control mechanism is seriously oxidized, resulting in poor starting contact. If the starter carbon brush is good, there is not enough voltage (rated voltage), and the starter will be difficult to work properly. The phenomenon is that when the fire is lit, there is no response.

It's also possible that there is a problem with the starter itself. For example, the flywheel of the starter does not swing, resulting in the starter and the engine not being connected together. The last thing is to check the battery to see if there is a problem with the battery.
