The reason for the big waste is that the syringe is not easy to use. Improper adjustment of fuel supply advance angle. The fuel supply of the fuel injection pump is too large. The air filter is clogged. The diesel engine is overloaded. Other reasons: insufficient compression ratio, too large or too small valve clearance, valve sticking or lax sealing between valve and valve seat, and wear of piston ring and cylinder liner are all important reasons for diesel engine to emit black smoke. Therefore, when judging, we should analyze the symptoms and troubleshoot in time.

What should I do if the diesel exhaust is big? Generation of waste gas: Due to the work done by combustion, the remaining non-combustible gases are basically waste gas. If the combustion is not good, the exhaust gas will not meet the standard. Can check the ignition, fuel injection, electronic control system and cylinder mechanical parts. After the waste gas is generated, it needs to be converted into air-friendly gas through a three-way catalyst. If there is a problem in the conversion process, the exhaust gas will not meet the standard, and the most common one is the damage of the three-way catalyst. It is suggested to go to the maintenance station to analyze the exhaust gas, see which exhaust gas composition has problems (which is CH\CO\NO), and then carry out maintenance.
