What happens when a diesel generator smokes?

There are generally three smoke situations. (1) Black smoke Why does a diesel generator emit black smoke when it is working well? The black smoke is caused by the diesel not being completely burned, forming black carbon and being discharged? this is the factor that causes black smoke. There are the following five types: Wear of piston rings and cylinder liners After the piston rings and cylinder liners are worn, the compression pressure is insufficient, resulting in a change in the normal mixture ratio. the end of the cylinder's compression stroke, causing the fuel to burn under anaerobic conditions. Produce carbon deposits. The fuel injector is not working properly. The fuel injector does not atomize or drip oil, so the fuel cannot be completely mixed with the air in the cylinder and cannot be completely burned. The phenomenonThe black smoke caused by a malfunctioning fuel injector is more evident when the diesel engine is running at low speeds. Since the air intake vortex in the cylinder is small during low speed operation, the possibility of oil droplets or oil jets scattered by the air flow is reduced and the droplets Oil remains longer, making it easier for black carbon discharges to form. The shape of the combustion chamber changes. The manufacturing quality of the combustion chamber shape does not meet technical requirements. If the compression gap is too large or too small and the piston is installed in the wrong position, the combustion will form. The chamber will be changed, thereby affecting the quality of the fuel and air mixture and worsening the fuel combustion conditions. Incorrect adjustment of the advance angle of the fuel supply (1) The advance angle of theFuel supply is too large and fuel is injected prematurely into the combustion chamber. Since the pressure and temperature in the cylinder are low at this time, the fuel cannot ignite and burn. When the piston rises, the cylinder reaches a certain pressure and temperature, the combustible mixture burns. (2) The fuel supply advance angle is too small, and the fuel injected into the cylinder is too late. Part of the fuel does not have time to form a combustible mixture and is separated or discharged. The fuel discharged with the exhaust gases is decomposed. at high temperature, forming black smoke. 5. The fuel supply is too large, which increases the amount of oil entering the cylinder, resulting in more oil and less gas and incomplete combustion of the fuel. Additionally, excessive workload, poor fuel quality and low temperatureand operating conditions can also cause black smoke from the exhaust. (2) Blue smoke Why does blue smoke appear? This is related to lubricating oil. The lubricating oil enters the cylinder and is heated and evaporates into blue oil vapor. Blue smoke is emitted with the exhaust gases. The main reasons are: the air filter is clogged, the air inlet is not regular or the oil level in the oil basin is too high (oil bath air filter). Lubricating oil is mixed with fuel. The piston rings are aligned and the cylinder gasket near the oil passage from the body to the cylinder head is blown. Wear of piston rings, pistons and cylinder liners (3) White smoke White smoke is caused by the white smoke emitted from the exhaust pipe of the diesel generator set when it is just started or when it is cold . It is formed by evaporation. oil and gas due tolow temperature in the cylinder of the diesel engine. This is especially true in winter. If the exhaust pipe still emits white smoke when the engine is hot, the diesel engine is considered defective. The main reasons are: the cylinder liner is cracked or the cylinder seal is damaged, cooling water enters the cylinder, and water mist or water vapor is formed when exhaust. Fuel injector has poor atomization and oil dripping. The fuel feed advance angle is too small. There is water and air in the fuel. The fuel injection pump pressure is too low or the piston, cylinder liner, etc. is damaged. are severely worn, resulting in insufficient compression force.
