Abstract
The engine cylinder liner of the utility model is the cylinder-shaped structure, and the top of the cylinder liner (3) is embedded with an abrasion reduction ring (6) whose inner diameter is less than that of the cylinder liner and more than the outer diameter of the piston. When the piston moves upward, the abrasion reduction ring (6) can scrape away carbon deposition outside the piston head and decrease the wear between the piston and cylinder liner, thereby prolonging the service life of the engine piston and the cylinder liner components and lowering the oil consumption.
Description
Technical field
The utility model belongs to technical field of engines, relates in particular to a kind of novel engine cylinder liner.
Background technique
The cylinder liner of motor plays supporting and leading role when pistons work.Because the work characteristics of piston, its head outside easily forms carbon distribution, thereby cause end mill phenomenon on the top of cylinder liner, be piston motion corresponding cylinder cover position serious wear when arriving top dead center, can cause like this and scurry on gas leakage, the machine oil and then crankcase pressure increases, consumption of lubricating oil is big consequence.
Summary of the invention
The purpose of this utility model overcomes the deficiency of above-mentioned prior art exactly, the new work engine cylinder liner that a kind of generation that reduces cylinder liner end mill is provided, reduces consumption of lubricating oil, prolong diesel engine piston and cylinder liner assembly working life.
The purpose of this utility model is existing like this: a kind of air cylinder sleeve of engine, be cylinder-like structure, and be inlaid with its internal diameter on the top of cylinder liner matrix less than the cylinder sleeve internal diameter and greater than the wearing ring of piston external diameter.
Adopt the technical solution of the utility model, when piston moved upward, wearing ring can scrape off the carbon distribution of piston crown periphery, had reduced the wearing and tearing between piston and the cylinder sleeve, thereby prolonged the working life of engine piston and cylinder liner assembly, also reduced the consumption of machine oil in addition.
Description of drawings
Accompanying drawing 1 is the utility model embodiment's a principle schematic.
Embodiment
Referring to Fig. 1, the matrix of air cylinder sleeve of engine of the present utility model (1) is a cylinder-like structure, and the to-and-fro motion of piston is played supporting and leading role.Ponding ring set (2) forms endless belt water cavity (4) in the outside on cylinder liner matrix (1) top (3) with cylinder liner matrix (1), gives sealing by O RunddichtringO (5).The barrel dliameter on cylinder liner matrix (1) top (3) is slightly larger than the following barrel dliameter in top, forms the convex-down structure, and the wearing ring of thin walled cylinder type (6) is embedded in the top (3) of cylinder liner matrix (1).Wearing ring (6) the internal diameter barrel dliameter following than cylinder liner matrix (1) top (3) is smaller and greater than piston external diameter, thereby has formed a positive convex structure again.When reciprocating motion of the pistons, the carbon distribution of piston crown is constantly wiped off by wearing ring (6), and is deflated immediately and takes away.
Claims (1)
1, a kind of air cylinder sleeve of engine is cylinder-like structure, it is characterized in that being inlaid with on the top (3) of cylinder liner matrix (1) its internal diameter less than the cylinder sleeve internal diameter and greater than the wearing ring (6) of piston external diameter.
