Maintenance Of Engine Cylinder

  • For heavy-duty trucks, the maintenance of diesel engine cylinder blocks is essential, which can extend the service life of the cylinder blocks  of engine cylinder.
  • For different seasons, maintenance varies. Before starting the truck, the diesel engine must be filled with sufficient coolant to avoid starting without water. Do not add cold water when the body temperature is too high to prevent the cylinder from cracking.
  • Pay attention to water (or add antifreeze) during outdoor low-temperature parking in winter to prevent the cylinder from freezing and cracking; the vehicle must be operated at a specified temperature, and cooling water is indispensable to prevent the engine from being too cold or overheating; before starting, check the oil level and the amount of oil reach the scale specified on the oil dipstick, add or replace if necessary; engine maintenance must strictly abide by the operating procedures to avoid undue human damage.
  • At the same time, the maintenance of the engine cylinder gasket is also very important. The engine cylinder gasket is mainly used to ensure the sealing between the cylinder block and the cylinder head joint surface to prevent air leakage and water leakage. However, because the cylinder gasket directly contacts the high temperature and high pressure gas, it is easy to be ablated during use, especially around the cylinder mouth curling. Once the cylinder gasket is burned, the working condition of the engine will be seriously deteriorated, and it is also easy to cause failure or damage of other related parts.
Maintenance Of Engine Cylinder
  1. The cylinder gasket is not installed evenly on the joint surface of the cylinder block and the cylinder head.
  2. The cylinder head is warped and deformed, the cylinder block is too uneven and the cylinder head is loosened, resulting in a leaky seal.
  3. Improper driving operation method, accustomed to violently increasing the accelerator, rapid acceleration, and high-speed running. Excessive pressure aggravates the broken of the cylinder gasket.
  4. Cylinder gaskets are of poor quality and uneven thickness; there are air bubbles in the mouth of the bag, uneven laying of asbestos or not tight hemming, etc.

So Regular Maintenance Is Very Important Of Engine Cylinder

  1. Check the surface of the cylinder head gasket for depressions, bumps, damage, etc.; check whether the flatness of the cylinder head and cylinder body meets the requirements, and then clean the cylinder head gasket, cylinder head and cylinder body, and blow them dry with high-pressure air to avoid dirt.
  2. The selected cylinder head gasket must be the original parts that meet the requirements (specifications and models) with reliable quality. When installing, pay attention to its up and down direction marks to prevent reverse installation and avoid man-made failures.
  3. Tighten the cylinder head bolts according to the technical specifications. As the center extends symmetrically to the two ends, the bolts are tightened to the specified torque in 2 to 4 times; it is more reliable to tighten it once in the hot state.

Therefore, when replacing the cylinder head gasket, you must be patient and careful to operate strictly in accordance with the technical standards, especially in strict accordance with the order, tightening torque and tightening methods specified by the engine manufacturer to tighten the cylinder head bolts. Only in this way can the high-quality seal of the cylinder head gasket be guaranteed. Avoid brutal operation to effectively extend the service life of the cylinder head gasket.
