Abstract
The utility model relates to a double-nozzle piston cooling nozzle assembly, and belongs to the technical field of engines. The double-nozzle piston cooling nozzle assembly comprises a nozzle body, a hexagon bolt is fixed at the upper end of the nozzle body, a positioning pin is arranged at the lower end of the nozzle body, the nozzle body is connected with a spraying pipe, the spraying pipe is connected with a split-flow pipe, and a main spraying hole and an auxiliary spraying hole are formed in the split-flow pipe. Oil sprayed through the main spraying hole enters an internal cooling oil channel through an oil inlet of a piston and is used for cooling the piston, and engine oil sprayed through the auxiliary spraying hole directly collides into the bottom of the piston and is used for cooling the bottom of the piston. The oil sprayed through the main spraying hole is different from the oil sprayed through the auxiliary spraying hole in amount, and oil spray sprayed through the main spraying hole is different from oil spray sprayed through the auxiliary spraying hole in direction. By the adoption of the spraying pipe with the main spraying hole and the auxiliary spraying hole, cooling flow is increased, the phenomenon that targeting efficiency is low because the oil spray is scattered when the amount of the oil sprayed through one spraying hole is too large is avoided, and targeting efficiency is improved.
Description
Technical field
The utility model relates to the piston cooling nozzle assembly of two spray orifices of an a kind of jet pipe band major-minor, for meeting a kind of piston cooling jet nozzle assembly of high performance diesel steel pistons cooling requirement, belongs to technical field of engines specifically.
Background technique
For reducing pollution protection environment, national Abgasgesetz is increasingly strict, diesel engine is carried out to height and strengthen that to meet emission request also extremely urgent.
For meeting highly-intensified diesel engine performance requirement, generally adopt steel pistons, steel pistons heat-conducting property is not as aluminium piston, and temperature drift, to its cooling having relatively high expectations.In the past for the designed spray orifice of jet pipe of cooling jet band of aluminium piston, the machine oil being sprayed by spray orifice enters oil duct in piston, near piston base oil inlet hole, arrange an aperture, flow out for cooling piston pin and lining of connecting rod small end from this aperture via the machine oil of oil duct in piston.Because steel pistons self-temperature is high, machine oil viscosity via oil cooling passage in it is lower, be not suitable for for cooling piston pin and lining of connecting rod small end, and the required Coolers oil mass of steel pistons is larger than aluminium piston, therefore the cooling jet of a spray orifice of a jet pipe band can not meet the cooling usage requirement of highly-intensified diesel engine steel pistons in the past.
Model utility content
The purpose of this utility model is to meet highly-intensified diesel engine steel pistons cooling requirement, simultaneously better lube pistons pin and lining of connecting rod small end, the piston cooling nozzle assembly that adopts two spray orifices of an a kind of jet pipe band major-minor, has increased cooling flow, has improved cooling effect.
The technological scheme providing according to the utility model, two spout piston cooling nozzle assemblies, comprise nozzle body, and hex head bolt is fixed in nozzle body upper end, and nozzle body lower end is provided with locating stud;
Described nozzle body is connected with jet pipe, and jet pipe is connected with ram's horns; On described ram's horns, be provided with main jet hole and secondary spray orifice.
The oil mass of described main jet hole ejection enters interior oil cooling passage by piston oil inlet hole, and for cooling piston, the machine oil being sprayed by secondary spray orifice is directly beaten in piston base, for cooling piston bottom.
Oil mass and the oily Shu Fangxiang of described main jet hole and the ejection of secondary spray orifice are all not identical.
The beneficial effects of the utility model: it adopts two spray orifices of a jet pipe band major-minor, has increased cooling flow, oil miconvergence of beams and cause the phenomenon that target practice efficiency is low while avoiding a spray orifice oil mass excessive, thus improve target practice efficiency; The machine oil of pair spray orifice ejection is directly used in cooling piston bottom, has realized the outer cold combination of cold-peace in piston, and reinforcement is cooling to piston, simultaneously lube pistons pin and lining of connecting rod small end; Consider diesel engine mucosal structure compactness, arrange that single jet pipe evaded the interference of piston cooling nozzle and all the other correlated parts, simple in structure.
Accompanying drawing explanation
Fig. 1 is the utility model structural front view.
Fig. 2 is the utility model structure worm's eye view.
Embodiment
As shown in Figure 1-2: two spout piston cooling nozzle assemblies, comprise nozzle body 1, nozzle body 1 upper end arranges hex head bolt 2, and nozzle body 1 lower end is provided with locating stud 3;
Described nozzle body 1 is connected with jet pipe 4, and jet pipe 4 is connected with ram's horns 5; On described ram's horns 5, be provided with main jet hole 6 and secondary spray orifice 7.
The oil mass that described main jet hole 6 sprays enters interior oil cooling passage by piston oil inlet hole, and for cooling piston, the machine oil being sprayed by secondary spray orifice 7 is directly beaten in piston base, for cooling piston bottom.
The oil mass that described main jet hole 6 and secondary spray orifice 7 spray and oily Shu Fangxiang are all not identical.
Working principle of the present utility model: piston cooling nozzle assembly is arranged on body inner chamber by the utility model, when diesel engine running, piston cooling nozzle commencement of fuel injection when main oil gallery reaches certain pressure, the oil mass difference spraying under different pressures, increases but be fuel injection quantity with the rising of pressure.
The oil mass being sprayed by main jet hole 6 enters interior oil cooling passage by piston oil inlet hole, for cooling piston, the machine oil being sprayed by secondary spray orifice 7 is directly beaten in piston base, for cooling piston bottom, realize the outer cold combination of cold-peace in piston, promote cooling effect, beat at the lubricating oil splash of piston base and for lube pistons pin and lining of connecting rod small end simultaneously.
