Features of control of assemblage cylinder piston group

The article touches upon the problem of increase of assembly of cylinder heads during repair of combustion engines. It analyzes the influence connections on combustion engines safety. It describes the method of cylinder heads for improvement of combustion engines safety. The technical state repair process control results are outlined. The need to diagnose cylinders by structural parameters by direct measurements with partial or complete engines dismantling is justified. The description of cylinders direct measuring order, the forming of wearing, possible errors of cylinder group details surfaces and cylinder-piston group details axes mutual location, crank mechanism and their impact on the cylinder wearing process is made. It is stated results of control in the course of repair of technical condition of cylinders of engines. Need of diagnosing of cylinders in structural parameters by direct measurements with partial or fill dismantling of engines is proved. The description of an order of performance of direct measurements of cylinders, the formed wear forms, possible errors of a relative positioning of surfaces and axes of details of tsilindroporshnevy group, a crank - the conrod mechanism and their influence on process of wear of cylinders is made.
