Description

Technical Field

[0001] The present application relates to the technical field of piston ring gap measurement assistance. Specifically, it relates to a sleeve for simulating the measurement of piston ring gap under the condition of the engine cylinder. Background Art

[0002] A piston ring is a metal ring used to be embedded inside a piston groove. The piston rings are divided into two types: compression rings and oil rings. The compression rings can be used to seal the combustible mixture in the combustion chamber; the oil rings are used to scrape off the excess oil on the cylinder. Currently, under the traditional condition, the measurement of the piston ring gap needs to be carried out before the piston ring is installed inside the engine cylinder block. When the piston ring is placed inside the engine cylinder block, the operator cannot actually detect the gap of the piston ring inside the engine cylinder block, making it difficult to adjust the gap of the piston ring and affecting the actual installation effect between the piston ring and the inside of the engine cylinder block.
