Abstract
The utility model relates to a diesel engine oil nozzle, which belongs to the structural design creation of diesel engine parts. The diesel engine oil nozzle is mainly used to resolve the technical problem of piston cooling and lubricating of a horizontal diesel engine of horizontal diesel engines. The technical scheme comprises that the oil nozzle is a cylindrical hollow structure, an outer peripheral surface of one end of the oil nozzle is in spline shape 2, the other end is a cone, the hollow inner portion of the cylinder is a conical structure, namely, the circle area of an oil outlet 4 is smaller than that of an oil inlet 5. The utility model can be applied to an oil nozzle of a main bearing seat of a horizontal type single-cylinder or double-cylinder diesel engine body.
Description
Technical field
The present invention relates to a kind of nozzle, a kind of specifically horizontal cylinder diesel engine oil injection nozzle that is applicable to single cylinder or twin-tub.
Background technique
After diesel engine is invented generation, on over 100 years, just do not stop around its technology of constantly bringing forth new ideas, horizontal cylinder diesel engine promptly is wherein a kind of.
Obviously, a diesel engine relates to up to a hundred of component, owing to model, power, size, structure difference, especially updating of structure respectively has its superiority-inferiority naturally, is difficult to its quality of comment, meet the efficient height in a word, discharging is few, and the diesel engine that rate of fault is low just should be good.For this reason, many people and company have dropped into a large amount of research and development, have applied for that this type of technology of national patent is also a lot, can't discuss one by one.
The engine oil nozzle for diesel engine that cooperates engine oil nozzle hole to use is design first of the present invention, is to make an effectively cooling and a lubricated important structure design of moving element generation in the internal-combustion engine.
Traditional internal combustion engine cooling is the high speed rotating that relies on bent axle, machine oil on the crank throw has just produced a centrifugal force along with the bent axle high speed rotating time, under action of centrifugal force, machine oil has just been got rid of and has been gone out, major part has been fallen back oil sump, and fraction just has been splashed to the cooling of carrying out piston on the piston and has lubricated.Not only efficient is low for this mode cooling piston, and also insufficient to the cooling of piston, and this just causes the working life of piston short.
The present invention overcomes the shortcoming of prior art for this reason, proposed a kind of on the body main bearing seat machining piston cooling engine oil nozzle hole, the engine oil nozzle for diesel engine of packing in the hole again comes piston is cooled off and lubricates, and this cooling and lubricating system are that a kind of new design produces.
Summary of the invention
Goal of the invention of the present invention just provides a kind of cooling and lubricated all the comparing fully that can impel piston, can effectively improve the horizontal single-double cylinder diesel cooling and lubricating piston oil injection nozzle in the working life of piston.
Realize that technological scheme of the present invention is such: engine oil nozzle for diesel engine, concrete structure is that engine oil nozzle for diesel engine 1 is the cylindrical body hollow-core construction, one end outer circumferential face is that spline-shaped 2, an end are cone 3, and cylindrical boring is cone structure, is the area of a circle of the area of a circle of oil outlet 4 less than filler opening 5.This nozzle is made with engineering plastics, all can be provided with on single cylinder or two cylinder diesel engine.
Beneficial effect of the present invention is: this cooling piston oil injection nozzle comes machine oil generation pressure is sprayed cooling to piston again with the rotation of bent axle, not only improved efficient, and to the cooling of piston and lubricated all compare fully, be more favourable this working life to raising cylinder liner and piston.
Description of drawings
Fig. 1 is the perspective view of engine oil nozzle for diesel engine of the present invention;
Fig. 2 is the generalized section of engine oil nozzle for diesel engine of the present invention.
Among the last figure, the 1st, engine oil nozzle for diesel engine, the 2nd, spline-shaped, the 3rd, cone, the 4th, oil outlet, the 5th, filler opening.
Embodiment
Below in conjunction with accompanying drawing of the present invention, further describe its embodiment.
Embodiment: engine oil nozzle for diesel engine, concrete structure is that engine oil nozzle for diesel engine 1 is the cylindrical body hollow-core construction, one end outer circumferential face is that spline-shaped 2, an end are cone 3, and cylindrical boring is cone structure, is the area of a circle of the area of a circle of oil outlet 4 less than filler opening 5.This nozzle all can be provided with on single cylinder or double-cylinder horizontal diesel.
Claims (1)
1, a kind of engine oil nozzle for diesel engine, it is characterized in that: engine oil nozzle for diesel engine (1) is the cylindrical body hollow-core construction, one end outer circumferential face is that spline-shaped (2), an end are cone (3), and cylindrical boring is cone structure, is the area of a circle of the area of a circle of oil outlet (4) less than filler opening (5).
