The engine cylinder is compressed, burning and combustible gas expanding space. In the process of gas combustion, the highest temperature of 2 (c) XK ~ 3000 ~ degrees it directly affected by the wall, and high temperature and high pressure gas outer wall and wind (or water), the cooling cylinder under large mechanical stress and thermal stress, so liner will have the enough strength and rigidity, and work less distortion. In addition, the movement of the piston cylinder block, plays a guiding role of piston cylinder walls with side pressure, thought of piston cylinder wall, make speed movement was strongly friction, is the most serious engine wear one surface, therefore, request the cylinder block must have a certain resistance.
A product performance,
This company produces the gas cylinder magnificent using boron iron cylinder liner, double, with high hardness metal casting, oily, wear resistance and thermal capacity, precision and instances.some at 7 above level and distribution rules, enlarges honing oil film distribution uniformity can make a good lubrication, reciprocating and oil consumption is small.
Second, gas cylinder disassembly
Note: some of the vehicles can tear open outfit, some car engine will unload disassembly. For four; Intermediate engine cylinder head, to remove the timing chain component, guide roller (70, 100) or chain guide plate (125), with the box open cylinder connecting bolts, can block out.
For two medium-range engine exhaust muffler, need to put down (if the cylinder with the intake, will also removed) device, and remove the cylinder and the cylinder block and the crankcase removed the connecting bolts, can block will pull out.
Cylinder in reverse order to install, note:
1 o-rings, gasket, pins must be replaced with a new one.
2 Fou gas engine inside surface coating. I
3 the piston to the open position.
4 when not falling within the crankcase chain.
Three of the cylinder block and check
1 check diameter cylinder
With inner batches (or in), qianbanbiao piston pin direction and vertical direction, elected, in the next three, six points in diameter determination of cylinder, the maximum diameter values as cylinder. If this value has exceeded the limit, should be boring grinding increase or replacement of the cylinder.
2 check cylinder surface deformation
With straightedge and HouBoGui check cylinder liners (note: will end with viscose trace clean), if the deformation limits should be greater than using grinding or replacement.
