What is the reason for the black smoke emitted from the refueling of the Shifeng agricultural tricyc

The reasons are as follows: 1. The combustible mixture is too thick.

2. There is too much oil in the engine fuel.

3. Piston rings or crankshafts.

Poor sealing of oil seals.

4. There is moisture in the fuel.

5. a spark plug.

Undesirable. 6. Air filter.

Too dirty. Workaround:

1. For the inspection and diagnosis of excessive concentration of combustible mixture, the carburetor should be checked.

and air filters.

2. The mixture of mixed oil and engine oil is not compared, or the grade of engine oil used is incorrect. If the oil mixture contains too much oil or the oil quality is poor, the oil of the flammable mixture cannot be completely burned, resulting in black smoke. The above phenomenon can also occur in two-stroke engines with separate lubrication and oil pump misalignment and excessive oil supply.

At this time, the oil pump should be checked and adjusted according to the regulations to ensure that the lubricating oil is supplied proportionally at different throttle openings.

3. Excessive wear or fracture of the four-stroke engine, as well as too much oil in the crankcase, will cause the oil to enter the combustion chamber and make the oil in the mixture excessive. If the crankshaft oil seal of a two-stroke engine is broken, it will also make the transmission.

The oil is strung into the crankcase and enters the combustion chamber with the mixture.

4. The reason for the mixing of water in the fuel is that the fuel in the fuel tank itself contains water, so the fuel tank should be cleaned and the fuel should be replaced. Another reason is because the cylinder gasket of a water-cooled engine is broken, and cold water enters the cylinder. If, in the absence of leakage, the water in the tank is consumed too quickly, and the exhaust smoke from the exhaust pipe is slightly white, this is mostly the reason and the head gasket should be replaced.

There is a lot of black smoke from the exhaust of the diesel engine, which is mostly caused by the incomplete combustion caused by uneven or excessive oil supply to each cylinder, insufficient air intake, poor atomization, and premature fuel injection time. (1) Remove the air filter and observe the exhaust smoke. If the black smoke emission improves, the fault is that the air filter is heavily polluted; (2) Check whether the oil supply time is too early, and adjust it too early; (3) When the engine is running, the oil cut-off test can be carried out item by item.

When a cylinder is cut off, the engine speed decreases, the black smoke decreases significantly, and the knocking sound becomes weaker or disappears, indicating that the cylinder is supplied with too much oil. If the engine speed changes small and the black smoke disappears, it means that the injection quality of the cylinder injector is poor.

Once the faulty cylinder is located, disassemble the injector. If necessary, the injector can be replaced with a new one for comparison. If the fault goes away when using the new injector, the original injector is faulty.

If the above method cannot eliminate the fault, if the plunger tappet of the fuel injection pump has an adjustment screw, check whether the fuel injection of each cylinder is consistent, and adjust it if necessary.

Shifeng agricultural tricycle refueling black smoke, mainly the following reasons, the first may be the combustible mixture is too thick, or the engine fuel in the amount of oil is too much, there is also a possibility of piston ring or crankshaft oil seal seal seal, and there is also a possibility of water in the fuel, which is the reason for the black smoke of Shifeng agricultural tricycle refueling.

Summary. In general, this can be caused by carbon deposits in the gasoline and oil circuits or incorrect gasoline blending ratios. If the gasoline mixing ratio is incorrect, it can lead to incomplete combustion, resulting in black smoke.

In addition, if there is carbon deposits in the gasoline line, it can also lead to incomplete combustion, resulting in black smoke.

In general, this situation may be caused by carbon deposits in the gasoline and oil circuits or incorrect gasoline mixing ratios. If the gasoline mixing ratio is incorrect, it may result in incomplete combustion, resulting in skin-wide black smoke. In addition, if there is carbon deposits in the gasoline line, it can also lead to incomplete combustion, resulting in black smoke.

The tricycle can't hit now, and when it does, it hugs to death.

And I feel that when I am ignition, I feel that there is an abnormal noise in the diesel engine.

Is it diesel or petrol.

For diesel, the original cylinder gasket was broken, and water entered the oil, and it was like this after the change.

If the diesel tricycle feels that there is an abnormal sound in the diesel engine when it is ignition, it may be due to a failure inside the diesel engine, such as damage to the piston, piston ring, and cylinder liner, or damage to the piston ring, resulting in the loosening of the piston rod, so that the piston rod hits the piston ring, resulting in a sound that is more than a bird. In addition, it may be due to the fact that there is no lubrication oil inside the diesel engine, which causes friction between parts to occur, and abnormal noise will also occur.

It is recommended to check whether the Nayuanshan piston, piston ring, cylinder liner and other parts of the diesel engine are damaged, and check whether the piston ring is loose, if there is a problem, replace the damaged parts in time, and check whether there is lubricating oil inside the diesel engine, if not, add lubricating oil in time.

Is it possible that there is a problem with the engine oil, and it feels like the piston is locked when you hit it.

After beating the belt gear, it does not rebound.

It is possible that it is caused by the damage of the piston ring, you can disassemble the piston ring to check whether the piston ring is worn or broken, if there is wear or fracture of the piston ring, you need to replace the piston ring more often.

Summary. There may be many reasons why a Shifeng agricultural tricycle emits black smoke, and some of the common ones include:1

The engine fuel mix is too thick. This can be caused by too much oil being added to the tank, or the oil pump and injector are not properly maintained. 2.

The air filter is clogged or damaged. A clogged air filter can cause air to not enter the engine, resulting in incomplete combustion and eventually black smoke. 3.

The spark plug is worn or incorrectly adjusted. This can cause the engine to burn incompletely, producing black smoke. 4.

Poor oil quality, such as the use of unclean oil or fuel. This affects engine combustion and can lead to black smoke. To solve these problems, it is recommended to check the fuel tank, oil pump and fuel injector, change the air filter, adjust or replace the spark plug, and use high-quality and clean oil.

A clogged air filter can cause air to enter the engine uncontrollably, resulting in incomplete combustion and eventually black smoke. 3.The spark plug is worn or incorrectly adjusted.

This may cause the engine to burn incompletely, producing black smoke. 4.Poor oil quality, such as the use of unclean oil or fuel.

This affects engine combustion and can lead to black smoke. To solve these problems, it is recommended to check the fuel tank, oil pump and fuel injector, change the air filter, adjust or replace the spark plug, and use high-quality and clean oil.

The tricycle is not emitting black smoke, and the black smoke is running out of oil.

Is the sound of the engine getting louder, dear?

The sound doesn't feel right.

Well, dear, you can check if the oil is insufficient, and because the valve clearance is too large.

As a result, the air intake is insufficient

I was tired halfway through, so I added some oil and walked for a while, and I couldn't walk.

Check if the oil is leaking, if the oil leaks, it will lead to the situation you said is how to repair it after it is finished.

It's been a year since I changed the oil, is there no oil, or how did I get it?

It's been a year, and that's a long time, dear

A big reason for your situation is the oil problem.

Because the oil has been used for a year, there is no lubrication effect.

It is necessary to drain all the old engine oil and then add the new oil parent

That's how to fix it.

Dredging the oil line

Then find the screws where the oil is placed.

Drain the old engine oil

After draining all the oil.

Add a new oil to you and you're pro

Summary. Hello dear! <>

Over-concentration of the mixture will also cause gasoline to exceed the standard, you can check these aspects separately, the focus is on the carburetor The following is the solution: replace the slightly smaller idle measuring hole. Adjust the height of the float, observe the oil level of the float chamber to the 2 5 places of the float chamber is the normal oil level, note that when the lower cover is removed to observe the oil level, the carburetor must be upright, in case the gasoline is spilled, resulting in inaccurate judgment of the oil level.

What is the cause of black smoke from a tricycle.

Hello dear! <>

Can you elaborate on your question? Whether it is an oil tricycle or an electric tricycle, it can better answer for you.

Hello dear! The causes of black smoke emitted by tricycles: blockage of air filter, too thick and wild carburetor mixing ratio, improper use of dampers, too high oil level to shout, wrong position of oil needle, excessive size of the main measuring hole or problems with the main measuring hole and foaming pipe, quality problems of the carburetor itself, etc., will cause black smoke from the tricycle.

Hello dear! <>

The mixture is too thick and will also cause the gasoline to exceed the standard, you can check these aspects separately, the focus is on the carburetor to Tong Jian as a solution: replace the slightly smaller idle measuring hole. Adjust the height of the float, observe the oil level of the float chamber to the 2 5 places of the float chamber is the normal oil level, pay attention, when removing the lower cover to observe the oil level, the carburetor must be upright, in case the gasoline is spilled out, and the bureau trousers cause inaccuracy in judging the oil level.
