Weichai Power always sends me short messages.

The new cylinder gasket doesn't match the old one, so the power will accelerate if there is a traffic jam. It doesn't matter, just run in for a while. In fact, changing the cylinder pad has little to do with power, but there will definitely be minor problems in the car after the year. If the power is weak, it does not rule out that the mechanic made some low-level mistakes during the installation, such as the bolt not being tightened and not being installed according to the regulations, which will cause it. Thanks for the car that has been fitted, no matter how hard it is repaired, it can't be returned! When replacing the cylinder gasket, tighten the diagonal of a single cylinder head first, and then tighten it clockwise one by one. Tighten the entire cylinder head in turn from front to back until it reaches the middle, and then tighten it from both sides of the middle image. As for the replacement of the four sets, there will be a running-in period for a while, and it will gradually become stronger after a while. The cylinder pad is located between the cylinder head and the cylinder block, also known as the cylinder seat. Its function is to fill the micro-pores between the cylinder block and the cylinder head, ensure the good sealing of the joint surface, and then ensure the sealing of the combustion chamber, and prevent the cylinder from leaking and the water jacket from leaking. If the power before replacing the cylinder gasket is normal and the power decreases after replacing it, the following possibilities are mainly considered: First, during the installation process, the cylinder head is not tightened to the required kilograms, resulting in poor sealing; Second, the quality of the new cylinder gasket is not good; Third, there is something wrong with the valve assembly. Fourth, the general cylinder gasket does not need to disassemble the valve train. Arguably, it will not be a problem with the valve train. If the repairman moves the valve mechanism, it may be that the gap between the intake and exhaust valves is wrong, and the valve gap should be readjusted. In addition, measure the cylinder pressure. If the cylinder pressure is normal, the timing may be wrong, resulting in poor power. Also, plug in all the sensors and read the data stream to see if the data is normal. You can also adjust the fuel supply or try to raise the valve a little.
