Why diesel smokes black smoke
Diesel often smokes black smoke as a result of incomplete fuel combustion. The reason for this color of the exhaust are hydrocarbons, which did not burn in the cylinder. These elements in this case are converted into soot. These elements in this case are converted into soot. Lack of oxygen or excess diesel fuel equally lead to black diesel exhaust.
Lack of oxygen or excess diesel fuel equally lead to black diesel exhaust, associated with the appearance of blue or blue exhaust of the diesel engine. In this article you will learn about it, associated with the appearance of blue or blue exhaust of the diesel engine, associated with the appearance of blue or blue exhaust of the diesel engine.
Black smoke from diesel is clearly visible during the day, Black smoke from diesel is clearly visible during the day. Black smoke from diesel is clearly visible during the day. Black smoke from diesel is clearly visible during the day, that the diesel fuel in the cylinder does not burn completely. that the diesel fuel in the cylinder does not burn completely, that the diesel fuel in the cylinder does not burn completely. that the diesel fuel in the cylinder does not burn completely, diesel does not start on "hot". diesel does not start on "hot", diesel does not start on "hot", power is lost due to large deviations in the composition of the working fuel-air mixture from the optimal parameters.
Black color of diesel exhaust: main reasons
One of the most harmless causes of black smoke is the low quality of diesel fuel (One of the most harmless causes of black smoke is the low quality of diesel fuel) One of the most harmless causes of black smoke is the low quality of diesel fuel. Exhaust color gradually normalizes after the immediate transition to better diesel.
Exhaust color gradually normalizes after the immediate transition to better diesel. Also the cause of a small amount of soot in the exhaust is clogging of the engine exhaust system. In other cases, the presence of black smoke from the diesel exhaust indicates that, what:
- there are problems with the fuel or air supply system of the diesel engine;
- there are problems with the fuel or air supply system of the diesel engine (there are problems with the fuel or air supply system of the diesel engine);
- there are problems with the fuel or air supply system of the diesel engine;
Black diesel exhaust is often caused by a clogged air filter or difficult air entry into the intake air., inaccuracies in the regulation of valve clearances or failures in the installation of gas distribution phases. inaccuracies in the regulation of valve clearances or failures in the installation of gas distribution phases. A black diesel exhaust also occurs when the boost pressure adjustment system fails, A black diesel exhaust also occurs when the boost pressure adjustment system fails (A black diesel exhaust also occurs when the boost pressure adjustment system fails, changing the shape of the diesel fuel torch, changing the shape of the diesel fuel torch).
changing the shape of the diesel fuel torch
changing the shape of the diesel fuel torch, changing the shape of the diesel fuel torch, the drop of compression in cylinders acts. the drop of compression in cylinders acts. the drop of compression in cylinders acts. The efficiency of self-ignition of the fuel-air mixture depends on the temperature of the compressed air at the time of fuel injection. At low compression, the temperature will not be enough for full combustion, At low compression, the temperature will not be enough for full combustion. A low-compression diesel engine is often not started in winter.
We also recommend reading the article about it, A low-compression diesel engine is often not started in winter. In this article you will learn about the basic nuances and the necessary equipment for measuring the pressure in the cylinders in the process of self-measurement of engine compression.

The diesel also has black exhaust smoke due to pump failures, The diesel also has black exhaust smoke due to pump failures. The diesel also has black exhaust smoke due to pump failures (early fuel supply) severe detonation may occur, increased noise when the engine is running in different modes. In the list of breakdowns of the fuel equipment note wear of nozzles and disturbance of the form of a torch of a saw, In the list of breakdowns of the fuel equipment note wear of nozzles and disturbance of the form of a torch of a saw. Prolonged driving on low-quality fuel quickly disables the pump, as low-grade diesel does not provide proper pump oil.
Turbocharger
Black diesel exhaust can also be caused by problems with the turbocharger, Black diesel exhaust can also be caused by problems with the turbocharger. Lack of tightness of the inlet tract often leads to this, that black smoke comes from the exhaust pipe of the diesel engine. Such smoke in this case can be seen at the time of regasification. On turbodiesel fuel supply at regasification increases, On turbodiesel fuel supply at regasification increases. For this reason, there is a lack of air in the cylinder for complete combustion of the fuel-air mixture, For this reason, there is a lack of air in the cylinder for complete combustion of the fuel-air mixture.
Prolonged driving with an early injection angle or faulty diesel injectors can cause prechamber burnout or bridge breakage. It is also likely to burn and destroy the pistons.
It is also likely to burn and destroy the pistons
It is also likely to burn and destroy the pistons, diesel injectors, diesel injectors. diesel injectors. Soot also penetrates the engine oil and quickly contaminates the engine. There is a violation of heat exchange, piston rings are quickly coked, clogged filters.
Clogging of oil channels of the internal combustion engine leads to a decrease in pressure in the lubrication system and increased wear of engine parts. Clogging of oil channels of the internal combustion engine leads to a decrease in pressure in the lubrication system and increased wear of engine parts (CPG), and valves (Timing). and valves. and valves, and valves, antiwear properties of additives in motor oil are lost.
The problem is diagnosed by the method of analysis of the state of engine oil. Just take out the probe and look at its viscosity. If the oil in the diesel is very liquid and even in the cold drips profusely from the probe, If the oil in the diesel is very liquid and even in the cold drips profusely from the probe, If the oil in the diesel is very liquid and even in the cold drips profusely from the probe. An increase in oil level also directly indicates the ingress of fuel into the crankcase.
An increase in oil level also directly indicates the ingress of fuel into the crankcase. An increase in oil level also directly indicates the ingress of fuel into the crankcase, as diesel oil washes away oil, as diesel oil washes away oil. as diesel oil washes away oil. It is problematic to operate a diesel engine with this fault, It is problematic to operate a diesel engine with this fault, It is problematic to operate a diesel engine with this fault.
