Q: how to control the diesel generator set and eliminate the engine load size carbon?

Answer: diesel generating set at high load running, exhaust smoke, black smoke production process generally thought that the high diesel engine load, increase in the number of fuel spray into the combustion chamber, the temperature and combustion chamber is higher, and mixture form uneven characteristics of diesel engine, this will cause less air combustion, part of the combustion chamber fuel under the condition of high temperature anaerobic decomposition, the aggregation formation of charcoal smoke (black). Charcoal smoke is not pure carbon, but a kind of polymer, main component is carbon (85%), but also contains a small amount of oxygen, hydrogen and ash content, and its composition varies with the different load of diesel engine change.Will put the carbon black smoke through the filter smoke collected under the electron microscope observation, can see a big charcoal smoke particle diameter around 0.05 mm.Diesel engine combustion in high temperature cracking reaction is inevitable, especially in the space of mixed combustion of diesel engine, surrounded by a high temperature gas liquid droplets, caused the cracking reaction is the most favorable condition, high-speed photography, confirmed that the combustion process in the check point will appear a lot of black smoke around, but in general, charcoal smoke can be found in the subsequent combustion air and complete combustion, make no black smoke exhaust.But if lack of air cylinder, mixing process is slow, so negative cylinder temperature drops due to inflation, and the carbon does not be aggregated into charcoal smoke burning.Formation of charcoal smoke makes incomplete combustion, the efficiency drop, high exhaust temperature, exhaust smoke, carbon deposit on the surface of combustion chamber, and the load cannot progress.Coke will also cause the piston ring or piston, valve and killed, such as fault, so don't promise to diesel engine work under the state of the overload for a long time.
