I have a Quanjiao 1 130 single-cylinder diesel engine. It is difficult to start after changing the four-piece suit, and it is hot. Ask the elders.

The fault phenomenon is not detailed enough! Startup difficulty: Did the professional repairman change four channels? Unprofessional people will have poor installation when repairing. For example, the piston ring is installed in the wrong direction or the ring mouth is facing the piston pin, which will cause insufficient cylinder pressure, and it is difficult for the piston to burn diesel oil without sufficient compression force when compressing air. Unprofessional maintenance will lead to the wrong choice of accessories. For example, the matching pistons are inconsistent, and the pistons cannot reach the top dead center, which will also cause difficulties in starting. It is also a common example that the piston is installed backwards! High temperature problems: for example, the cylinder gasket will cause high temperature, and the low oil pressure will also cause high temperature (the journal and bearing bush are worn, and the oil path of the main bearing cover is worn), the ignition time is early, the machine temperature is high, and there is no nozzle hole, which will also cause high temperature! Hehe, according to the above, please check it from simple to complex!
