Measures To Prevent Early Wear Of Cylinders

1 It is forbidden to run the engine for a long time. Because the engine is running rapidly for a long time, the nozzle is poorly atomized, the fuel and air are not uniformly mixed, the combustion is incomplete, and the cylinder is prone to coke formation, which intensifies the cylinder wear. In addition, long-term idle operation also accelerates wear and tear.

2 Start properly and minimize the number of starts. If the machine stops for less than 15 minutes, do not turn off the fire to reduce the number of starts. When starting the engine, do not put the throttle to the maximum position forcibly starting, otherwise the diesel fuel injected into the cylinder will be too much, resulting in no starting. Even if it can be started, due to excessive fuel in the cylinder, the combustion is incomplete, causing coke and increasing wear. . Generally speaking, when the temperature is below 15 °C, do not add the throttle at the start of the start, idle the crankshaft for a few turns, feel relaxed and then add a small throttle to start.

3 Do not bomb the throttle. The bombing not only causes deformation of the connecting rod and the crankshaft, but even the crankshaft is broken, and the combustion is incomplete.

4 It is strictly forbidden to carry sick work. Maintenance should be strengthened and repaired in time. If the gap of the piston ring is kept in compliance with the regulations, do not use the piston ring that does not meet the requirements to reduce the carbon deposit in the cylinder; check the piston "offset cylinder" according to the engine assembly process; check the high-speed valve clearance and oil supply regularly. The advance angle makes the fuel and air mix evenly, the combustion is normal, and the carbon deposition is reduced; when the connecting rod and the crankshaft are bent and twisted, it should be corrected in time, and the axial clearance of the crankshaft is guaranteed to meet the technical requirements.
