The diesel generator light tower engine is difficult to start and the exhaust pipe emits a lot of black smoke, which is the result of incomplete diesel combustion
① The quality of light tower generator oil is inferior.
② The air intake is not smooth, and the air filter is blocked.
③ The injection timing is adjusted too early.
④ The needle valve of the injector has poor sealing and drip oil leakage.
⑤ The injection pressure is too low.
⑥ The light tower generator fuel supply of the fuel injection pump is too large, and the combustion deteriorates.
⑦ Low cylinder pressure, poor atomization.
