Abstract
The utility model belongs to the technology of the automobile engine, and relates to an automobile engine cylinder block structure, in particular to an automobile engine cylinder block additionally provided with oil injection nozzles in a cylinder. The cylinder block comprises cylinder bores, a left suspension surface, a right suspension surface, a front end surface, a rear end surface, a cylinder block water cavity and main oil pipes, wherein the main oil pipes of the cylinder block are additionally provided with the oil injection nozzles. Because the main oil pipes of the cylinder block are additionally provided with the oil injection nozzles, engine oil flow quantity and flow velocity distribution can be optimized, the heat dissipation efficiency of each cylinder barrel is guaranteed to be consistent, the size change of each cylinder barrel of the cylinder block is even under the heat condition, and the defects of the scuffing, the engine oil burning and the abnormal sound of the engine can be effectively eliminated. Meanwhile, parts in the cavity are guaranteed to be fully lubricated, and the abrasion of the parts is lowered to the maximum extent.
Description
Technical field
The utility model belongs to car engine machine technology, relates to a kind of housing structure of motor car engine, is especially specifically related to a kind of automobile engine cylinder-body that increases cylinder-in oil-jet mouth.
Background technique
Motor car engine is the heart component of automobile, the complex machines being formed by a plurality of mechanisms and system, and its Main Function is to realize heat energy to the conversion of mechanical energy.Housing assembly is the skeleton of motor, and all major parts and the annex of motor is installed, and bears the various load in motion.Its structure has left and right side to hang face, front/rear end.The housing assembly of motor is mainly comprised of cylinder body, cylinder or cylinder liner, cylinder cap, head gasket and oil sump etc., and cylinder body is that gray cast iron or aluminum alloy are cast.Therefore cylinder body cylinder barrel inner body needs lubricated and heat radiation fully.
This engine cylinder-body is because power is large in the market, inner machine oil is cooling insufficient, the part lubricating systems such as cylinder inside crankshaft are preferential, can not be initiatively lubricated thoroughly, cause engine overheat, the pin of connection piston, bent axle owing to not obtaining the lubricated mechanical wear causing fully, has shortened the life-span of body in engine working process.
Model utility content
The utility model is for deficiency of the prior art, a kind of automobile engine cylinder-body that increases cylinder-in oil-jet mouth is provided, overcome the shortcoming on existing cylinder body, under the prerequisite that does not change engine cylinder body structure, optimize cooling machine oil velocity flow profile and flow, effectively eliminate the defects such as engine scuffing, burn oil, wearing and tearing.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
Increase an automobile engine cylinder-body for cylinder-in oil-jet mouth, on cylinder body, comprise that cylinder hole, left and right side hang face, front/rear end, also comprise cylinder body water cavity and main oil pipe, on cylinder body main oil pipe, increase oil nozzle.By to increasing main oil pipe oil nozzle in cylinder body, optimize oil flow rate and velocity flow profile, guaranteed that each cylinder barrel heat loss efficiency is consistent, each cylinder barrel of cylinder body dimensional changes under hot state is even, effectively eliminate engine scuffing, burn oil, abnormal sound defect, guarantee the sufficient lubrication of part in chamber simultaneously, reduced to greatest extent the wearing and tearing of part.
As preferably, connecting duct on oil nozzle.By oil nozzle and conduit by machine oil spray feed to before cannot sufficient lubrication position.
As preferably, on the main oil pipe of each cylinder, be equipped with oil nozzle.Described main oil pipe increases oil nozzle altogether everywhere, each place of one two three four cylinders, and oil nozzle is to increase on original main oil pipe basis, does not change main oil pipe shape and position.
According to a kind of automobile engine cylinder-body that increases cylinder-in oil-jet mouth of the technical solution of the utility model, compare with former cylinder body type, the utility model structure does not change former engine cylinder-body main oil pipe design size and oil pipe bore size, the oil nozzle at newly-increased optimization position is simple in structure, effectively eliminate engine scuffing, burn oil, abnormal sound, mechanicalness inordinate wear.
Accompanying drawing explanation
Fig. 1 is the structural representation of oil nozzle of the main oil pipe of automobile engine cylinder-body of the present utility model.
Fig. 2 is the main oil pipe of automobile engine cylinder-body of the present utility model and the left view of oil nozzle.
Fig. 3 is the main oil pipe of automobile engine cylinder-body of the present utility model and the plan view of oil nozzle.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail:
Increase an automobile engine cylinder-body for cylinder-in oil-jet mouth, on cylinder body, comprise that cylinder hole, left and right side hang face, front/rear end, also comprise cylinder body water cavity and main oil pipe 1, on cylinder body main oil pipe 1, increase oil nozzle 2, connecting duct on oil nozzle 2.By to increasing main oil pipe 1 oil nozzle 2 in cylinder body, optimize oil flow rate and velocity flow profile, guaranteed that each cylinder barrel heat loss efficiency is consistent, each cylinder barrel of cylinder body dimensional changes under hot state is even, effectively eliminate engine scuffing, burn oil, abnormal sound defect, guarantee the sufficient lubrication of part in chamber simultaneously, reduced to greatest extent the wearing and tearing of part.
On the main oil pipe 1 of each cylinder, be equipped with oil nozzle 2.Described main oil pipe increases 1 and adds oil nozzle 2 altogether everywhere, each place of one two three four cylinders, and oil nozzle 2 is to increase on original main oil pipe 1 basis, does not change main oil pipe 1 shape and position.
In a word, the foregoing is only preferred embodiment of the present utility model, all equalizations of doing according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
Claims (3)
1. increase an automobile engine cylinder-body for cylinder-in oil-jet mouth, on cylinder body, comprise that cylinder hole, left and right side hang face, front/rear end, also comprise cylinder body water cavity and main oil pipe (1), it is characterized in that: the upper oil nozzle (2) that increases of cylinder body main oil pipe (1).
2. engine cylinder-body according to claim 1, is characterized in that: the upper connecting duct of oil nozzle (2).
