6 cylinder head flatness7, head of bolt preload8, cylinder head pad quality9 、 piston ring cylindricity and elasticity10 cylinder surface finish
1, piston and cylinder clearance2, piston ring end clearance3 、 piston ring backlash4 cylinder cylindricity5, valve tightness
Mainly machining accuracy, the sealing pad between the cylinders also plays a big role. There is the problem of design, basically mature products will not appear airtight problems
