The utility model relates to an improved configuration of an oil nozzle, which is assembled on a locomotive engine with a crankcase and a piston, and a crankshaft is arranged in the crankcase. The oil nozzle is fixed on the intake side of the line from the center of the crankshaft to the center of the piston, and the opening of the oil nozzle faces the bottom of the piston on the exhaust side of the line from the center of the crankshaft to the center of the piston. Therefore, it can effectively reduce the working temperature of the piston, prolong the service life of the piston, and reduce the wear and tear of parts.
Description
Technical field
The utility model, about a kind of improved arrangement of oil injection nozzle, espespecially relates to a kind of improved arrangement that is applicable to the oil injection nozzle of locomotive engine.
Background technique
, in locomotive engine, by cylinder head, cylinder block, crankcase, linked haply at present, and can in each parts, be pre-formed the internal oil passages that is connected to carry out lubricated as camshaft of long-range component.Due to the chamber at oil pump place be position in crankcase right-hand part, machine oil chamber normally utilizes an entity connecting tube to be communicated with between a crankcase internal oil passages (its end openings in crankcase top, and connect with cylinder block oil circuit entrance).
The shortcoming of above-mentioned existing lubricant oil road structure is, not only must make in addition connecting tube, also will make in addition relevant lock and pay seat, and then increase the demand for crankcase inner space.Certainly, follow various part and the assembling performance problem come and the consideration of each damage parts probability, showing the not desirable design of existing lubricant oil road structure.Given this, existing technology, as the model utility of " Lubricating oil circuit structure of engine " that Taiwan patent announcement number is announced for No. I373550 ties up to this problem of discussion, please refer to as follows.
Please refer to Fig. 2 and Fig. 3, it is existing locomotive engine sectional view and existing engine inner engine oil oil circuit schematic diagram.Shown in figure, locomotive engine is mainly sequentially linked by cylinder head 81, cylinder block 82, crankcase 83.In cylinder head 81, be provided with a camshaft mechanism chamber 811, camshaft mechanism chamber 811 has been installed with a camshaft 812.Cylinder block 82 has been installed with a piston rod member 821, and crankcase 83 has been installed with a bent axle 836.In addition, have a chain drive-belt 84 to extend in cylinder head 81, cylinder block 82, crankcase 83, see through sprocket wheel 85,86, one end is hung on bent axle 836, and the other end is hung on camshaft 812.
Moreover machine oil is sent by oil pump 91 (being positioned at crankcase) pressurization, injects the camshaft mechanism chamber 811 of cylinder head 81 through the interior oil circuit 92 of cylinder block 10.Machine oil slave oil-in chamber is pumped out, oil circuit 93 in elongated groove 94, crankcase and enter oil circuit 92 in cylinder block, and then be transported to that engine need to lubricate and each cooling position.After lubricated, be affected by gravity and be back to oil sump, so Zhou Erfu makes circulation.Complete machine oil is lubricated at piston rod member 821 bearing places, to splash mode cooling piston bottom, to reduce pistons work temperature, extends piston working life, reduces parts depreciation.
Hanging outdoor unit oil nozzle mode is also set in addition, with suitable angle, machine oil is sprayed to piston base, can reduce the high temperature that piston is caused by combustion chambers burn.It is better that it improves the more traditional mode of splashing of effect, but nozzle mounting point and oil spout angle can affect cooling effect.Common mode is that hanging outdoor unit oil nozzle structure is located at and the same side, oil spout position at present, to approach the angle of parallel rod, sprays to piston base, and in some engine, this kind of mode cooling effect is still limited.
Model utility content
Main purpose of the present utility model ties up to the improved arrangement that a kind of oil injection nozzle is provided, and can effectively reduce pistons work temperature, extends piston working life, reduces parts depreciation.
For reaching above-mentioned object, the improved arrangement of a kind of oil injection nozzle of the utility model, is mounted on one and has on the locomotive engine of a crankcase and a piston, and crankcase content is provided with a bent axle.It is characterized in that: oil injection nozzle is installed in crankshaft center to the online air inlet side in piston center, and the opening of oil injection nozzle is towards the piston base of crankshaft center online exhaust side to piston center.
Above-mentioned oil injection nozzle is installed in crankshaft center to the online air inlet side in piston center, and the opening of oil injection nozzle is towards the piston base of crankshaft center online exhaust side to piston center.
By the configuration of said engine oil nozzle, can effectively reduce pistons work temperature, extend piston working life, reduce parts depreciation.
In addition, on crankcase tank wall of the present utility model, also can be installed with a fixed plate, in order to fixation machine oil nozzle.
Moreover aforesaid fixed plate can have one and lock hole, in order to lock oil injection nozzle, lock the air inlet side that hole can be positioned at locomotive engine.

Embodiment
For the ease of persons skilled in the art, understand and realize the utility model, now describing by reference to the accompanying drawings embodiment of the present utility model.
Please refer to Fig. 1, is the planimetric map of one of the improved arrangement preferred embodiment of the utility model oil injection nozzle.The improved arrangement of a kind of oil injection nozzle of the present embodiment, is mounted on a locomotive engine, comprising: one has crankcase 1, a piston 3, an oil injection nozzle 5 and a fixed plate 4 of a bent axle 2.
The oil injection nozzle 5 of the present embodiment is an external hanging type oil injection nozzle, is fixedly arranged on the fixed plate 4 on crankcase 1 tank wall, and fixed plate 4 have one be positioned at locomotive engine air inlet side 6 lock hole 41, in order to lock oil injection nozzle 5.
Moreover the oil injection nozzle 5 of the present embodiment is positioned at bent axle 2 centers to the air inlet side 6 of the piston 3 online L in center, and the opening of oil injection nozzle 5 arrives piston 3 bottoms of the online exhaust side 7 in piston 3 centers towards bent axle 2 centers.
By the configuration of said engine oil nozzle 5, can effectively reduce piston 3 operating temperatures, extend 3 working lifes of piston, reduce parts depreciation.
Although described the utility model by embodiment, but those of ordinary skills know, in the situation that not departing from spirit of the present utility model and essence, just can make the utility model have many distortion and variation, scope of the present utility model is limited to the appended claims.
