Why is it difficult to start the rig and why is there black smoke from the exhaust pipe?
Difficulty in starting the engine and a lot of black smoke from the exhaust pipe are the result of incomplete combustion of diesel fuel.
① Poor quality of diesel fuel
② air intake is not smooth, air filter clogging.
③ Injector timing adjusted too early.
Injector needle valve sealing is poor, there are oil dripping and leaking phenomenon.
⑤ Injector pressure too low.
⑥ Injector pump oil supply too large, combustion deterioration.
⑦ Low cylinder pressure, poor atomization.
