Measures to prevent early wear of the cylinder

1. New or major overhaul of the diesel engine must be strictly running after the test run in order to formally put into operation.

2. Regular maintenance of the air filter, oil filter, diesel filter, make it in good condition, this is to prevent dust and impurities into the cylinder by air, fuel and oil channel, reduce cylinder wear, prolong the service life of the engine is one of the important measures.

3. Replace the oil pan oil regularly, and the oil must be in accordance with the specification. Replace the oil pan, the oil pan should be cleaned carefully and lubrication, its method is to do with a clean diesel oil deterioration, the same amount is poured into the oil pan, start the engine idle running for 3-5 minutes, then wash out the diesel, wipe the oil pan, and clean the oil filter finally, the prescribed amount of oil.

4. The non first starting with the water, otherwise easy to make the cylinder and quench crack.

5. Keep the normal engine operating temperature, high dilution oil, lubricating condition deterioration; too low to produce acid corrosion caused by pitting spalling. General suitable working temperature of 70-80 degrees Celsius, evaporation type engine can be a bit higher.

6. When starting the engine should be pre lubrication, because when the engine flameout, the lubrication system oil flow to the vast majority of the oil pan, the surface of pairs in dry friction and semi dry friction, if immediately start, is bound to exacerbate the cylinder wear rate, so when starting the first crank crankshaft dozens of circle, the advance by certain lubrication motor side surface.

7. After starting the engine warm-up time, when the engine temperature is low, the cylinder and other parts has not got sufficient lubrication, or accelerate the cylinder liner, piston and piston ring, shaft and bearing wear neck. When the engine temperature reached 40 degrees Celsius, 60.

8. Forbid long time overload operation.

9. Prohibit the engine from running for a long time. Because the engine rapid long-term operation, poor atomization nozzle, mixture of fuel and air is not uniform, the incomplete combustion in the cylinder is easy to produce coke, exacerbated by cylinder wear. In addition to the long run idle speed up wear and tear.

10. To start, and to minimize the number of starting times, such as the shutdown is not more than 15 minutes, do not have to extinguish, to reduce the number of starting. When starting the engine throttle to maximum position will not be forced to start, or sprayed into the cylinder of the diesel engine can not start too much, cause, even to start, because too much fuel in cylinder, incomplete combustion, coke formation and increased wear. Generally speaking, when the air temperature is below 15 DEG C, don't start refueling door, idling crankshaft laps, feel relaxed after the small throttle starting.

11. No boom. Boom not only caused the connecting rod, crankshaft deformation, and even breaking the crankshaft, and the burning is not complete.

12. Is strictly prohibited to stop operation. We should strengthen the maintenance, timely maintenance, such as keeping the piston ring gap is not in conformity with the provisions, does not meet the requirements of the piston ring and cylinder to reduce carbon deposition; according to the engine assembly process inspection of piston cylinder offset ", if not in conformity with the provisions, timely find the reason to exclude; high speed valve clearance and fuel supply advance angle to make regular inspection. Uniform mixture of fuel and air combustion, reduce carbon deposition; connecting rod, crankshaft bending and twisting, should be promptly corrected, and ensure the axial clearance of the crankshaft with the technical requirements.

13. When the operation is not allowed to change the accelerator, as a result of changes in the work load to change the throttle, it should be slow to carry out.

14. Establish a clean consciousness. Maintenance, just keep the tools and parts of body, clean, lest the iron, silt and other debris into the cylinder and the cylinder to produce early wear
