Description
Technical field
The present invention relates to auto parts machinery technical field, more particularly, relate to a kind of automobile with sending outEngine block structure.
Background technology
At present, in the cylinder barrel of automobile engine cylinder-body, cylinder sleeve is installed, common with piston and cylinder capComposition combustion chamber. Cylinder sleeve is divided into dry sleeve and the large class of wet sleeve two. The back side of dry sleeve does not contactCooling water, and the back side of wet sleeve contact cooling water. Dry sleeve thin thickness, simple in structure, addWork is convenient. Wet sleeve directly contacts cooling water, so be conducive to the cooling of engine, is conducive toThe miniaturization and of engine. The cylinder sleeve choosing, is to ensure the normal prerequisite using of engine,If liner backs can not overlap internal surface of hole laminating with machine body cylinder, will affect the heat transfer of cylinder sleeve,Cause cylinder sleeve, piston, piston ring thermic load to increase, and this situation is anti-with water-thermometer thermometricDo not reflect cylinder sleeve and obtain true temperature, therefore will accelerate carbon distribution and the snap ring of piston ring groove machine oil,Under duty, cannot ensure the sealing property between piston, piston ring, cylinder sleeve, early stageLubricating oil carry-over phenomenon will unavoidably occur; And cylinder sleeve of the prior art mainly contain Cast iron liner,Metallurgical cylinder cover and stainless steel cylinder sleeve, the Cast iron liner production cycle is long, and processing capacity is large, material profitLow by rate, and Cast iron liner is cast directly in engine cylinder-body blank adding man-hour requirement,Reach again the technical indicator of designing requirement by machining operation; Metallurgical cylinder cover needs special establishingStandby production, cost is high; It is more that stainless steel cylinder sleeve adds man-hour clout, and stock utilization is low.Existing cylinder sleeve is all difficult to meet the requirement of automobile engine, especially to intensity, hardness, resistance toThe requirement of the performances such as mill property and corrosion resistance.
Therefore, owing to there is above-mentioned technological deficiency in prior art, be, technology people in this areaThe technical problem that member is urgently to be resolved hurrily.
Summary of the invention
Object of the present invention, for a kind of engine for automobile housing structure is provided, is intended to solve existingThe technical problem existing in technology.
For achieving the above object, the invention provides following technical scheme:
A kind of engine for automobile housing structure, comprises cylinder body body, cylinder hole, wearing layer, potteryEnamel coating, copper coating and aluminium alloy layer, described cylinder body body is provided with cylinder hole, described cylinder hole inwallBe provided with wearing layer, described wearing layer is cast iron layer, described wearing layer and described cylinder hole inwall itBetween be provided with ceramic layer, copper coating and aluminium alloy layer, described wearing layer contact ceramic layer, described cylinderHole inwall contact aluminium alloy layer, is provided with copper coating between described ceramic layer and aluminium alloy layer.
Preferably, described wearing layer thickness is 2.5 millimeters.
Preferably, described ceramic layer thickness is 1.0 millimeters.
Preferably, described aluminium alloy layer thickness is 0.5 millimeter.
Preferably, described copper coating thickness is 0.2 millimeter.
Usefulness of the present invention is: the inwall in cylinder block arranges wearing layer, not only solvesIn prior art cylinder block from lining during due to the different burning of material coefficient of thermal expansion inconsistentProblem, has effectively reduced the heat distortion amount in cylinder hole, has improved engine cylinder-body simultaneouslyThe accuracy of manufacture, extended service life; The aluminium alloy layer and the ceramic layer that arrange have reduced cylinderOverall weight, reduced fuel consume; And be provided with copper between ceramic layer and aluminium alloy layerCoating, has improved radiating effect, has broad prospects. The present invention is simple in structure, userJust, wear-resisting effective, long service life, weight is little, and fuel consume is few.
