What is the smoke of the Daewoo diesel engine at 3,000 rpm

What color smoke, big.

Hello dear, the reasons for the smoke of diesel engines may be:1Fuel filter clogged:

Filters in the diesel fuel system can become clogged, which can lead to a decrease in the fuel pressure of the diesel engine, which can cause the fuel to not enter the engine in time, resulting in insufficient combustion and thus smoke. 2.Insufficient fuel pressure:

Insufficient fuel pressure in a diesel engine may cause the fuel to fail to enter the engine in time, resulting in insufficient combustion and thus smoke. 3.Blocked intake tract:

The intake tract of a diesel engine may be blocked, affecting the air intake, resulting in insufficient combustion and thus smoke. 4.Piston rings or piston assembly wear:

Wear of the piston rings or piston components may cause the fuel of the diesel engine to not have enough time to enter the piston rings, resulting in insufficient combustion and thus smoke. 5.Timing gear damaged:

Damage to the timing gear can cause the fuel of the diesel engine to not have enough time to enter the piston rings, resulting in insufficient combustion and thus smoke. 6.Cylinder gasket damage:

Damage to the cylinder gasket will cause the fuel of the diesel engine to not enter the engine in time, resulting in insufficient combustion and smoking.

Pro, there are 1 reasons why diesel engines suddenly smokeThe cause of black smoke: It indicates that some diesel atomized particles are discharged without burning in the cylinder.

There are generally three reasons: (1) Excessive fuel supply and overload operation of the diesel engine. (2) The fuel injection pressure of the injector is low and the degree of diesel atomization is poor.

3) The oil supply is too late, and the temperature of the engine is low. 2. The cause of white smoke: it indicates that the atomized diesel injected into the cylinder is discharged before it is completely combusted.

There are three main reasons: (1) The fuel injector is stuck, the pressure is insufficient, and the diesel atomization is poor. (2) There is a lot of air in the oil circuit and water in the diesel.

3) The same reason as the black smoke, the oil supply is too late. 3. The cause of blue smoke: it indicates that the engine is burning oil.

There are three main reasons for this: the gap is too large.

Under the normal working temperature of the diesel engine, the exhaust smoke color should be colorless or light gray, the so-called colorless is not completely colorless, can not be as colorless as the gasoline engine, but is accompanied by a faint gray in the colorless, which is the normal exhaust smoke exhaust black smoke (soot) black smoke is also called soot, the black smoke from the exhaust of the diesel engine is mainly caused by the fuel mixture is too thick, the combustible mixture is not formed well or the combustion is imperfect.

When the diesel engine is in good technical condition and working normally, the diesel fuel injected into the combustion chamber can be fully mixed with the air and completely combusted, and the exhaust gas discharged should be colorless, or with a little light blue or light gray gas. If the exhaust gas emitted by the diesel engine is white, black and blue under common working conditions, it means that the exhaust of the diesel engine is abnormal, and the cause should be found and the fault should be eliminated.

The essential reason for the black smoke emitted from the exhaust gas is: too much fuel injected into the combustion chamber by the diesel engine, which is too high mixed with air or poorly mixed, resulting in incomplete diesel combustion, and the unburned diesel is decomposed by high temperature to form carbon black, and the exhaust gas is discharged together with the exhaust gas to form black smoke.

Summary. Hello kiss happy to answer for you, abnormal kiss. There are generally three reasons: first, the oil supply is too much, and the diesel engine is overloaded; Second, the injector oil pressure is low, and the degree of diesel atomization is poor; The third is that the oil supply is too late, and the temperature of the engine is low.

Hello. Hello, I am glad to answer for you, abnormal kiss. There are generally three reasons for this:

First, the oil supply is too much, and the diesel engine is overloaded; Second, the injector oil pressure is low, and the degree of diesel atomization is poor; The third is that the oil supply is too late, and the temperature of the engine is low.

Oh. What is normal.

The smoke you smoke is not too heavy, if not very heavy, it is a normal kiss.

That's the normal smoking kiss.

Generally, there are three kinds of smoke situations, (1) black smoke why diesel generators will emit black smoke, black smoke is because the diesel fuel is not fully combusted, the formation of carbon black is discharged, in fact, there are five factors that lead to the appearance of black smoke: piston rings, cylinder liners and other wear piston rings, cylinder liners wear out, causing insufficient compression pressure, so that the cylinder at the end of the compression stroke, the normal proportion of the mixture gas mixture changes, so that the fuel burns under oxygen-free conditions, resulting in carbon deposits. The injector works poorly, and the injector does not atomize or drip oil, so that the fuel cannot be fully mixed with the air in the cylinder, nor can it be fully burned.

The phenomenon of black smoke exhaust caused by poor injector operation is more obvious when the diesel engine is running at low speed. Because the intake vortex in the cylinder is weaker when running at low speeds, the possibility of oil droplets or oil bundles being washed away by the air flow is reduced and the residence time is longer, which makes it easier to form carbon black discharge. The shape of the combustion chamber changes the manufacturing quality of the combustion chamber shape does not meet the technical requirements, so that the compression gap is too large or too small and the piston position is installed incorrectly, which will change the shape of the combustion chamber, thereby affecting the mixed quality of fuel and air, and making the fuel combustion conditions worse.

Improper adjustment of the oil supply advance angle (1) The oil supply advance angle is too large, the fuel is sprayed into the combustion chamber too early, because the pressure and temperature in the cylinder are low at this time, the fuel can not be ignited and burned, when the piston goes up, the cylinder reaches a certain pressure and temperature, and the combustible mixture is combusted. (2) The advance angle of fuel supply is too small, the fuel injected into the cylinder is too late, and a part of the fuel is separated or discharged before it has time to form a combustible mixture, and the fuel discharged with the exhaust gas is decomposed by high temperature, and black smoke is formed. 5.

The oil supply is too large, so that the amount of oil entering the cylinder increases, resulting in more oil and less gas, and incomplete fuel combustion. In addition, excessive workload, poor fuel quality, and low operating temperatures can also cause black smoke from the exhaust. (2) Why does blue smoke appear in blue smoke, which is related to lubricating oil, which enters the cylinder and evaporates into blue oil and gas.

Blue smoke is emitted along with the exhaust gases, and the main causes are: blocked air filter, poor air intake, or high oil level in the oil basin (oil bath air filter). Lubricating oil is mixed into the fuel.

The piston rings are counterparted, and the cylinder gasket burns out near the oil passage of the machine body leading to the cylinder head. Piston rings, pistons, cylinder liners wear (3) white smoke and white smoke is because the diesel generator set is just started or in the cold state, the exhaust pipe emits white smoke, which is formed by the low temperature in the cylinder of the diesel engine, and the evaporation of oil and gas. This is especially noticeable in winter.

If white smoke still comes out of the exhaust pipe when the engine is warmed up, it is judged to be a diesel engine failure. The main reasons are as follows: the cylinder liner has cracks or the cylinder gasket is damaged, the cooling water enters the cylinder, and water mist or water vapor is formed when exhausting.

The injector is poorly atomized and has oil dripping. The oil supply advance angle is too small. There is water and air in the fuel.

The pressure of the fuel injection pump is too low or the piston and cylinder liner are seriously worn, resulting in insufficient compression force.
